fabric-mcp-server

The server utilizes official Hyperledger Fabric SDKs and loads all critical configuration (e.g., wallet paths, connection profiles, user IDs) from environment variables, preventing hardcoded secrets. It functions as a bridge, meaning the overall security posture heavily relies on the proper setup and security of the underlying Hyperledger Fabric network and the management of the user identity wallet. The HTTP transport, built with Express, handles basic error responses. While `express-rate-limit` is a dependency of the MCP SDK, no explicit rate limiting or advanced authentication for the `/mcp` endpoint is configured within the provided server code. This implies that the server expects to operate in a controlled environment where the AI assistant's access is implicitly authorized. Chaincode arguments are passed directly, making the security of the smart contracts' input validation critical.
