MCP server for Substrate-based chains

[jakehemmerle]

Project Abstract

mcp-polkadot aims to expose any Substrate-based chain's on-chain state to AI agents via the Model-Context Protocol (MCP). More examples of MCP can be found here

Grant level

• Level 1: Up to $10,000, 2 approvals
• Level 2: Up to $30,000, 3 approvals
• Level 3: Unlimited, 5 approvals (for >$100k: Web3 Foundation Council approval)

Application Checklist

• The application template has been copied and aptly renamed (project_name.md).
• I have read the application guidelines.
• Payment details have been provided (Polkadot AssetHub (USDC & DOT) address in the application and bank details via email, if applicable).
• I understand that an agreed upon percentage of each milestone will be paid in vested DOT, to the Polkadot address listed in the application.
• I am aware that, in order to receive a grant, I (and the entity I represent) have to successfully complete a KYC/KYB check.
• The software delivered for this grant will be released under an open-source license specified in the application.
• The initial PR contains only one commit (squash and force-push if needed).
• The grant will only be announced once the first milestone has been accepted (see the announcement guidelines).
• I prefer the discussion of this application to take place in a private Element/Matrix channel. My username is: @_______:matrix.org (change the homeserver if you use a different one)

Hi @jakehemmerle nice to talk to you again. I see you marked 0% for DOT payment, however at least 50% DOT (vested linearly over two years) is mandatory now for the grants program. Would you be willing to accept half the payment in DOT and if so could you update this?

Hey Kegan! I hope all is well in your world. Just updated it.

Another thing, I now realize that grants for individual contributors might aim for a max $10k grant instead of max $30k. Would it be better to decompose this into a smaller set of milestones and aim for the $10k instead?

Thanks @jakehemmerle much appreciated. I have marked the application as ready for review and will ping the rest of the committee for comment.

To answer your question, I would leave as is for now and you can always change it down the line if it isn't accepted. Thanks!

A small suggestion from me would be to not call it mcp-substrate but rather mcp-polkadot. Would that work?

Is there a reason, semantically, that mcp-polkadot is more descriptive? This would work for any Substrate-based runtime (eg. Polkadot, Astar, Entropy, etc).

Developer tooling & resources will benefit from consolidation around the Polkadot brand, given the branding overhaul initiated across the ecosystem in the past months/year.

These two non-exhaustive links might provide a bit more context:

• https://forum.polkadot.network/t/one-repo-to-rule-them-all-a-data-driven-look-at-polkadot-s-monorepo/5976
• https://forum.polkadot.network/t/polkadot-developers/9788

Ideally you want to reduce possible confusion and reduce cognitive load on people that don't have the full history in mind.

In short, it's all Polkadot.

@KarimJedda Right on, thanks for the context. Happy to change to mcp-polkadot.

@keeganquigley can you let me know what is missing from the review? If payment details are the bottleneck, can you let me know what email to send them to?

[keeganquigley]

Thanks @jakehemmerle yes can you please send them to [email protected]

Much of the team is ooo this week, sorry for the delay.
