Implementation Reference
- src/index.ts:110-128 (handler)Handler for the rpc_discover tool. Extracts the server URL from arguments, creates an HTTPTransport and OpenRPC Client, calls rpc.discover method on the server, and returns the formatted result.
case "rpc_discover": { const server = String(request.params.arguments?.server); if (!server) { throw new Error("Server is required"); } let transport = new HTTPTransport(server); let client = new Client(new RequestManager([transport])); const results = await client.request({ method: "rpc.discover" }); return { toolResult: { content: [{ type: "text", text: JSON.stringify(results, null, 2) }], isError: false } }; } - src/index.ts:68-82 (registration)Tool registration in the ListToolsRequestHandler. Defines the name, description, and inputSchema (requiring 'server' URL) for the rpc_discover tool.
