🧹 Nitpick comments (9)
airbyte/secrets/util.py (1)

15-29: Useful utility function with minor style improvement opportunity.

The function correctly checks secret availability by calling get_secret with allow_prompt=False. Would you consider simplifying the control flow by removing the unnecessary else clause, wdyt?

def is_secret_available(
    secret_name: str,
) -> bool:
    """Check if a secret is available in any of the configured secret sources.

    This function checks all available secret sources for the given secret name.
    If the secret is found in any source, it returns `True`; otherwise, it returns `False`.
    """
    try:
        _ = get_secret(secret_name, allow_prompt=False)
-    except exc.PyAirbyteSecretNotFoundError:
-        return False
-    else:
-        # If no exception was raised, the secret was found.
-        return True
+        return True
+    except exc.PyAirbyteSecretNotFoundError:
+        return False
airbyte/mcp/server.py (1)

25-37: Good error handling with a minor improvement opportunity.

The function handles both KeyboardInterrupt and general exceptions appropriately. Would you consider being more specific about which exceptions to catch in the general case, or perhaps logging the full traceback for debugging purposes, wdyt?

def main() -> None:
    """Main entry point for the MCP server."""
    print("Starting Airbyte MCP server.", file=sys.stderr)
    try:
        asyncio.run(app.run_stdio_async())
    except KeyboardInterrupt:
        print("Airbyte MCP server interrupted by user.", file=sys.stderr)
-    except Exception as ex:
-        print(f"Error running Airbyte MCP server: {ex}", file=sys.stderr)
+    except Exception as ex:
+        import traceback
+        print(f"Error running Airbyte MCP server: {ex}", file=sys.stderr)
+        traceback.print_exc(file=sys.stderr)
        sys.exit(1)

    print("Airbyte MCP server stopped.", file=sys.stderr)
airbyte/mcp/_local_dev.py (2)

47-52: Consider consistent return structure for error cases.

The error returns use {"error": "..."} structure while success returns {"code": "...", "instructions": "...", "filename": "..."}. For better API consistency, should we standardize on a common response structure that includes status indicators, wdyt?

Also applies to: 55-60


64-66: Empty config dictionaries might be confusing in generated code.

The template uses empty dictionaries {} as placeholders for source and destination configs. Users might not realize they need to fill these in. Could we add comments in the template or use more descriptive placeholders like {"config_key": "config_value"}, wdyt?

airbyte/mcp/_cloud_ops.py (2)

28-37: Consider making api_root parameter optional with default.

The api_root parameter is annotated as optional (str | None) but seems to always be used with a fallback to CLOUD_API_ROOT. Should we make it truly optional by defaulting to None in the function signature, wdyt?

def get_cloud_sync_status(
    workspace_id: Annotated[str, Field(description="The ID of the Airbyte Cloud workspace.")],
    connection_id: Annotated[str, Field(description="The ID of the Airbyte Cloud connection.")],
-   api_root: Annotated[str | None, Field(description="Optional Cloud API root URL override.")],
+   api_root: Annotated[str | None, Field(description="Optional Cloud API root URL override.")] = None,
    job_id: Annotated[int | None, Field(description="Optional job ID. If not provided, the latest job will be used.")] = None,
) -> JobStatusEnum | None:

39-43: Enhance docstring to explain secret fallback behavior.

The docstring mentions environment variables but doesn't explain the full secret resolution process. Could we clarify that it will use any configured secret managers first, then fall back to environment variables, wdyt?

airbyte/mcp/_local_code_templates.py (1)

23-23: Long lines in template strings

Lines 23 and 32 exceed the 100 character limit. Since these are within template strings that will be written to files, would it make sense to keep them as-is to maintain the intended formatting in the generated scripts? Alternatively, we could break them into multiple lines, but that might affect the output formatting. wdyt?

Also applies to: 32-32

airbyte/secrets/hydration.py (1)

17-17: Consider making the global mask URL configurable?

The URL is currently hardcoded. Would it be beneficial to allow this to be configured via an environment variable for flexibility in different environments? wdyt?

airbyte/mcp/_local_ops.py (1)

87-111: Consider extensibility for other secret managers

The function currently only handles GoogleGSMSecretManager. Would it make sense to add a comment indicating that support for other secret managers could be added here in the future, or perhaps create a more generic interface? wdyt?

🔇 Additional comments (44)
airbyte/__init__.py (1)

158-158: LGTM! Clean integration of the MCP module.

The addition follows the established pattern for exposing submodules in the public API. Nice and consistent!

Also applies to: 179-179

tests/integration_tests/test_all_cache_types.py (2)

20-23: Clean import organization.

The explicit imports and reorganization improve readability. Good refactoring!


144-144: Excellent migration to public API.

Switching from the private _config attribute to the public get_config() method is the right approach. This aligns well with the secret hydration changes throughout the codebase, wdyt?

airbyte/destinations/base.py (1)

267-267: Perfect use of hydrated config for connector execution.

Using _hydrated_config instead of _config ensures that secret references are properly resolved before being passed to the destination connector. This is exactly what we want for secure operations, wdyt?

pyproject.toml (2)

78-78: Good use of extras for development dependency.

Adding pydantic-ai with the mcp extra as a dev dependency is a clean approach for MCP-related development tooling.


178-178: CLI script entry point follows established patterns.

The airbyte-mcp script entry point is consistent with the existing pyairbyte and pyab scripts. Nice consistency!

airbyte/constants.py (1)

128-143: Excellent documentation for the secret hydration feature.

The SECRETS_HYDRATION_PREFIX constant is well-defined with comprehensive documentation. The JSON example makes it crystal clear how to use secret references in configuration. The docstring follows good practices by referencing the relevant module for more details, wdyt?

airbyte/sources/base.py (2)

295-295: LGTM! Security improvement by using hydrated config for discovery.

This change ensures that secret references are properly resolved before passing the config to the connector subprocess during discovery operations. This aligns well with the new secret hydration architecture introduced in the PR.


641-641: LGTM! Consistent use of hydrated config for read operations.

Similar to the discovery method, this ensures that secret references are resolved before execution. This maintains consistency across all connector operations and improves security by preventing raw secret references from being passed to subprocesses.

airbyte/sources/registry.py (3)

15-15: Great migration to Pydantic BaseModel!

The switch from dataclass to Pydantic provides better data validation, serialization, and integration with the MCP tooling. This is a solid architectural improvement, wdyt?

Also applies to: 72-72


90-92: Nice addition of suggested streams metadata.

The new suggested_streams field will be helpful for MCP tools to provide better guidance to users about which streams to select. The optional typing with default None is appropriate here.


157-157: Correct extraction of nested suggested streams.

The extraction logic properly handles the nested "suggestedStreams" -> "streams" path from the registry entry. The use of .get() with fallback to None is safe and appropriate for optional data.

airbyte/secrets/util.py (1)

49-53: Excellent secret reference handling implementation.

The logic properly strips the SECRETS_HYDRATION_PREFIX and handles the secret reference format. This integrates well with the broader secret hydration architecture introduced in this PR.

airbyte/records.py (1)

151-155: Excellent defensive programming improvement!

The switch from direct dictionary access to .get() with a fallback prevents potential KeyError exceptions when keys are missing from the pretty case lookup. This makes the method more robust and aligns with the updated docstring, wdyt?

airbyte/mcp/server.py (1)

16-22: Well-structured MCP server initialization!

The module-level initialization of secrets and tool registration is clean and follows a logical order. The separation of tools into different modules promotes good code organization.

airbyte/secrets/__init__.py (1)

59-83: Excellent documentation of the new secret reference feature!

The documentation clearly explains the secret reference mechanism and provides a helpful JSON example. One minor suggestion - would it be worth mentioning that secret references are processed recursively in nested configurations, wdyt? This could help users understand that the feature works with complex nested config structures.

airbyte/cloud/workspaces.py (2)

160-160: Good alignment with the secret hydration architecture.

Using _hydrated_config ensures that secrets are properly resolved before deployment to the cloud. The lint suppression is appropriate here since this is an intentional use of the internal API designed for this purpose.


208-208: Consistent pattern for destination deployment.

Same good pattern as the source deployment - using the hydrated config ensures secrets are resolved for cloud deployment operations.

airbyte/_connector_base.py (6)

127-127: Smart approach to validate hydrated config during setup.

Validating the hydrated config ensures that secret references are resolved and valid before storing the raw config. This catches secret resolution issues early, wdyt?


132-143: Well-documented distinction between raw and hydrated config.

The documentation clearly explains that get_config() returns the raw config without secrets hydrated. This preserves the external API contract while enabling internal secret hydration.


145-151: Clean internal API for hydrated configuration.

The _hydrated_config property provides a clean interface for internal operations that need resolved secrets. The property pattern ensures lazy evaluation and consistency.


163-163: Good choice to hash hydrated config.

Using hydrated config for hashing ensures that the hash represents the actual configuration that will be used by the connector, including resolved secrets. This makes the hash more meaningful for caching and comparison purposes.


175-175: Consistent pattern for validation with secret hydration.

The validation logic correctly handles both explicit config parameters and stored config, ensuring secrets are hydrated in both cases before validation.


323-323: Appropriate use of hydrated config for connector execution.

Using _hydrated_config for the check operation ensures the connector receives fully resolved configuration with secrets available.

airbyte/mcp/_local_dev.py (1)

84-86: Clean registration pattern for MCP tools.

The registration function follows a clean pattern for integrating with FastMCP. This looks good for modularity and testing.

airbyte/mcp/_cloud_ops.py (2)

54-56: Clean and concise sync status retrieval logic.

The logic for getting sync results and returning job status is well-structured and handles the optional job_id parameter correctly.


59-61: Consistent registration pattern with other MCP modules.

The registration function follows the same clean pattern as the local dev tools, maintaining consistency across the MCP module architecture.

airbyte/mcp/__init__.py (1)

174-180: Clean module structure!

The module properly imports and exports the server submodule with clear documentation.

airbyte/mcp/_local_code_templates.py (2)

1-1: Copyright year appears to be in the future?

The copyright year shows 2025. Should this be 2024 to match the current timeframe? wdyt?


178-190: Well-structured template generation function

The get_full_script_text function provides a clean interface for generating scripts with proper parameter substitution.

airbyte/mcp/_util.py (2)

19-27: Robust dotenv loading with proper error handling

Good implementation with type flexibility and clear error messaging.


46-106: Comprehensive config resolution with security considerations

Excellent implementation that:

  • Handles multiple config sources (dict, Path, secret name)
  • Detects and rejects hardcoded secrets
  • Provides helpful error messages with guidance on using environment variables
  • Properly merges configurations using deep_update
airbyte/secrets/hydration.py (2)

20-55: Well-implemented recursive hydration logic

The hydration functions properly handle nested structures and create deep copies to avoid mutating the original config.


140-171: Excellent secret detection implementation

The function comprehensively detects hardcoded secrets by checking against both global and connector-specific masks, encouraging the use of secret references.

airbyte/mcp/_connector_registry.py (4)

1-1: Inconsistent copyright year

This file shows 2024 while other new files show 2025. Should these be consistent? wdyt?


84-91: Pylint warning is a false positive

The warning about too few public methods can be safely ignored - ConnectorInfo is a Pydantic data model that doesn't require additional methods.


108-116: Smart use of contextlib.suppress for resilient metadata retrieval

Good defensive programming - the function continues gracefully even if metadata or config spec retrieval fails.


18-81: Well-designed connector filtering logic

The list_connectors function provides flexible filtering with clear logic flow - filtering by install types, then keyword, then connector type. The documentation is comprehensive and helpful.

airbyte/mcp/_local_ops.py (6)

1-43: Clear and comprehensive configuration documentation!

The CONFIG_HELP provides excellent guidance on how to use configuration options, including secret references and layering configs. This will be very helpful for users.


45-85: Well-structured validation function with proper error handling!

The function cleanly separates concerns: connector loading, config resolution, and validation check. The tuple return pattern (is_valid, message) is clear and useful.


113-142: Clean stream listing implementation!

Good job on keeping this function focused and simple. The configuration resolution and stream retrieval flow is clear.


144-172: Good schema retrieval implementation!

The function follows the same clean pattern as the others, with proper config resolution before accessing stream metadata.


225-277: Excellent sync implementation with smart defaults!

I really like the "suggested" streams feature with graceful fallback to all streams. The flexible stream parameter handling (string or list) is also user-friendly.


279-294: Clean tool registration logic!

Good separation between the tool that doesn't need CONFIG_HELP (list_connector_config_secrets) and those that do. The description concatenation approach is elegant.

🛠️ Refactor suggestion

Consider consistent return types and remove unnecessary else

Two suggestions here:

  1. The function returns either list[dict[str, Any]] or str, which could make it harder for callers to handle. Would it be better to raise an exception or return a typed result object? wdyt?
  2. The static analysis correctly identifies that the else block is unnecessary after the return statement.

🧹 Nitpick comments (3)
airbyte/mcp/_local_code_templates.py (3)

23-23: Line length exceeds 100 characters - could we break this up?

The logging warning message is quite long. What do you think about breaking it into multiple lines for better readability, wdyt?

-    logging.warning("'.env' file not found. Please ensure it exists and contains the necessary credentials.")
+    logging.warning(
+        "'.env' file not found. Please ensure it exists and contains the necessary credentials."
+    )

32-32: Another line length issue - could we format this more readably?

Similar to the previous comment, this error message is quite long. Would you consider breaking it up for better readability, wdyt?

-        sys.exit(f"Error: Environment variable '{var_name}' not set. Please add it to your .env file.")
+        sys.exit(
+            f"Error: Environment variable '{var_name}' not set. "
+            f"Please add it to your .env file."
+        )

31-31: Consider using f-strings consistently throughout the template

I noticed mixed usage of f-strings and .format() placeholders. For consistency within the generated script, would you consider standardizing on f-strings throughout, wdyt? This would make the generated code more modern and consistent.

For example:

-        logging.error(f"Missing required environment variable: {var_name}")
+        logging.error(f"Missing required environment variable: {var_name}")
-            logging.info(f"Using default value for optional environment variable: {var_name}")
+            logging.info(f"Using default value for optional environment variable: {var_name}")
-            logging.info(f"Optional environment variable not set: {var_name}")
+            logging.info(f"Optional environment variable not set: {var_name}")

1-3: Nice file structure and clear purpose!

The copyright header and docstring clearly establish the file's purpose. Good foundation for the template system.


4-26: Clean template setup with good error handling

The script template has solid foundations with proper imports, logging configuration, and environment file handling. The optional exit approach for missing .env files is thoughtful - gives users flexibility while providing clear warnings.


28-44: Excellent environment variable helper functions

These utility functions provide robust error handling and clear logging. The distinction between required and optional variables is well-implemented. The default value handling in get_optional_env is particularly thoughtful.


46-80: Comprehensive source configuration with excellent error handling

The source configuration section is well-structured with proper exception handling, connection verification, and stream selection. The comments providing alternative stream selection options are helpful for users. The logging throughout provides good visibility into the pipeline execution.


82-119: Well-designed data processing section with good user guidance

The data reading and DataFrame conversion logic is solid. I particularly appreciate:

  • Clear error handling for each stream conversion
  • Informative logging with row counts
  • The prominent comment directing users to add their processing logic
  • Defensive programming with the if results.streams: check

121-151: Thoughtful destination handling with practical considerations

The destination configuration mirrors the source setup well. The commented-out alternative approach for destination check failures (lines 147-149) shows good awareness of real-world connector behavior. The conservative approach of exiting by default is appropriate for safety.


153-174: Clean pipeline execution with appropriate error handling

The final pipeline execution section is well-structured. The separation of read and write operations with individual logging provides good visibility. The error handling ensures failures are properly logged and the script exits gracefully.


178-210: Comprehensive documentation template

The documentation template covers all essential aspects:

  • Installation instructions
  • Configuration guidance
  • Running instructions
  • Best practices
  • Helpful links to official documentation

This will provide users with a complete getting-started experience. The use of placeholders for dynamic content is well-designed.

39-44: Consider edge cases in pipeline name generation?

The pipeline name generation logic looks good, but I'm wondering about potential edge cases. What happens if the connector names contain special characters or if the generated pipeline_id becomes too long for filesystem constraints? Should we add some validation or sanitization here? wdyt?

 pipeline_id = pipeline_name.lower().replace(" ", "_").replace("'", "")
+# Sanitize pipeline_id to ensure it's filesystem-safe
+pipeline_id = "".join(c for c in pipeline_id if c.isalnum() or c in "_-")
+pipeline_id = pipeline_id[:50]  # Limit length for filesystem compatibility

10-12: Placeholder function looks good for now.

The placeholder structure is clean and ready for future implementation. The docstring accurately describes the intended purpose.

airbyte/mcp/_coding.py (3)

13-28: Great function signature with comprehensive annotations.

The use of Annotated with Field descriptions provides excellent type hints and documentation for the MCP tool interface. This will help users understand what each parameter expects.


77-81: Excellent return structure for MCP tool.

The return dictionary structure is well-designed, providing the generated code, setup instructions, and a suggested filename. This gives users everything they need to get started.


84-86: Clean tool registration implementation.

The registration function is concise and follows the FastMCP pattern correctly.

airbyte/mcp/_coding_templates.py (2)

4-175: Comprehensive and well-structured script template.

The generated script template is excellent! It includes:

  • Proper error handling and logging
  • Environment variable management with helpful utilities
  • Connection verification for both source and destination
  • Flexible stream selection
  • Data processing with DataFrame conversion
  • Clear comments and structure

This will generate very usable pipeline scripts for users.


178-210: Helpful documentation template with clear instructions.

The documentation template provides excellent step-by-step instructions covering installation, configuration, and usage. The links to connector-specific documentation are particularly valuable.

Check template variable consistency?

I noticed the template is being formatted with source_connector_name and destination_connector_name, but looking at the template in _coding_templates.py, it uses {source_name} and {destination_name}. Should we verify these variable names match between the template and the formatting call? wdyt?


🏁 Script executed:

#!/bin/bash
# Check template variable consistency between files
echo "Variables used in _coding.py formatting:"
grep -n "\.format(" airbyte/mcp/_coding.py -A 5

echo -e "\nVariables expected in template:"
grep -n "{.*}" airbyte/mcp/_coding_templates.py | head -20

Align pipeline template variables with SCRIPT_TEMPLATE placeholders
It looks like SCRIPT_TEMPLATE in _coding_templates.py uses {source_name} and {destination_name} (along with {source_config_dict} and {destination_config_dict}), but in airbyte/mcp/_coding.py (lines 62–67) we’re calling:

SCRIPT_TEMPLATE.format(
  source_connector_name=source_connector_name,
  source_config_dict={},
  destination_connector_name=destination_connector_name,
  destination_config_dict={},
)

This mismatch will raise a KeyError at runtime. Should we update it to:

- pipeline_code: str = SCRIPT_TEMPLATE.format(
-   source_connector_name=source_connector_name,
-   source_config_dict={},
-   destination_connector_name=destination_connector_name,
-   destination_config_dict={},
- )
+ pipeline_code: str = SCRIPT_TEMPLATE.format(
+   source_name=source_connector_name,
+   source_config_dict={},
+   destination_name=destination_connector_name,
+   destination_config_dict={},
+ )

wdyt?

SCRIPT_TEMPLATE.format do not match the placeholders defined in SCRIPT_TEMPLATE,
causing a KeyError. Update the keys in the format call to match the placeholders
exactly: replace source_connector_name with source_name and
destination_connector_name with destination_name, while keeping
source_config_dict and destination_config_dict as is.

Fix line length to satisfy linting rules?

The linter is flagging line 23 as too long (109 > 100 characters). Should we break this into multiple lines? wdyt?

Same template variable issue for destination.

Similar to the source configuration, the destination template uses {destination_name} but the formatting call uses destination_connector_name. Should we fix this consistency issue? wdyt?
