MCP Time server error

[polymathematic]

What happened?

MCP integration is working great overall. Big fan. I hit a simple one that seems to throw an error, though:

Adding the time mcp server to librechat.yaml causes the following error:

LibreChat  | 2025-02-12 02:36:01 info: [MCP][datetime] Connection state: connecting
LibreChat  | 2025-02-12 02:36:01 info: [MCP][datetime] Connection state: error
LibreChat  | 2025-02-12 02:36:01 error: [MCP][datetime] Connection failed: spawn python ENOENT

Thank you. Python based MCP servers are not supported yet, simply because the core project that spawns the processes have no Python dependencies. You can work around this with MCP Gateway MCP supergateway (other projects that bridge MCP connections)

I will look into this. Thank you.
