Mcp Poi

What is Mcp Poi?

Mcp Poi is a Model Context Protocol server that processes binary files and prepares blockchain transactions for the Proof of Invention (PoI) protocol. It integrates with the PoI API to generate Merkle root hashes and returns formatted transaction data for blockchain execution. It is designed for developers and users who need to anchor digital inventions on a blockchain using Claude Desktop or other MCP clients.

How to use Mcp Poi?

Clone the repository, install dependencies with npm install, and build the server with npm run build. Set the API_TOKEN environment variable with a bearer token obtained from Molecule’s Discord. Add the server to your MCP client (e.g., Claude Desktop) using the npx mcp-poi command with the token. The server exposes the tool create_proof_of_invention_request, which accepts a file path and returns a transaction request object containing the recipient address, Merkle root hash, and value.

Key features of Mcp Poi

• Outputs a formatted transaction request (to, data, value).
• Integrates with the PoI API via bearer token authentication.
• Works with Claude Desktop, Cursor, and other MCP clients.
• Can be combined with wallet and filesystem MCP servers.

Use cases of Mcp Poi

• Anchoring a digital invention (e.g., an idea file) as a Proof of Invention on blockchain.
• Preparing transaction data for automated submission via an EVM wallet MCP server.
• Building a pipeline where a file is processed, hashed, and the hash is sent to the PoI anchoring address.
• Verifying the integrity of a document by creating an on-chain timestamp with its Merkle root.

FAQ from Mcp Poi

What tool does Mcp Poi provide?

The server provides one tool: create_proof_of_invention_request. It accepts a file path and returns a transaction request object.

What environment variable is required?

The API_TOKEN environment variable must be set to a valid bearer token for the PoI API.

How do I get an API token?

You can request a new API token on Molecule’s Discord Server at https://discord.gg/k4ER7vZcj8.
