Integration for requesting API tokens through Molecule's Discord server for authentication against the PoI API References repository hosting for the MCP POI Server code Provides integration with npm package registry for dependency installation and package distribution Mentioned as compatible with the mcp-server-fetch Python package from PyPI Defines input/output schemas for the tool using TypeScript type definitions

How do I use Proof of Invention?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Proof of Invention create a proof of invention for my patent draft document" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

Environment Variables

API_TOKEN: Your API bearer token for authentication against the PoI API. You can request a new token on Molecule's Discord Server: https://discord.gg/k4ER7vZcj8

Usage

The server provides a tool called create_proof_of_invention_request that accepts a file path returns prepared transaction data suitable for blockchain execution. This can be reused by your favorite tool that can sign and submit transactions. The binary content should be provided by the MCP client (e.g., Claude Desktop or Cursor).

Adding to Claude Desktop

"poi": { "command": "npx", "args": ["mcp-poi"], "env": { "API_TOKEN": "the api token" } }

Plays nicely with other MCP servers

Our complete Claude desktop config looks:

{ "mcpServers": { "mcp-cryptowallet-evm": { "command": "npx", "args": ["@mcp-dockmaster/mcp-cryptowallet-evm"], "env": { "PRIVATE_KEY": "" } }, "filesystem": { "command": "npx", "args": [ "-y", "@modelcontextprotocol/server-filesystem", "/Users/stadolf/Downloads", "/Users/stadolf/Documents" ] }, "poi": { "command": "npx", "args": ["-y", "mcp-poi"], "env": { "API_TOKEN": "" } } } }

Prompts

| Create a poi hash from the "idea.md" file in my Documents folder ... | send and Eth transation with the poi hash to the poi's to address on the base blockchain

Tool Schema

Input:

{ filepath: string; // A path of a binary }

Output:

{ transaction_request: { to: string, // a PoI anchoring address (usually starts with 0x1dea) data: string, // the merkle root hash that represents the PoI value: string, // 0 } }
