execute: async () => { const result = getChainId(wagmiConfig) return { content: [ { type: "text", text: result.toString(), }, ], } }, - Zod schema defining the input parameters for the 'get-chain-id' tool: an empty object indicating no parameters are required.
parameters: z.object({}), - packages/metamask-mcp/src/tools/get-chain-id.ts:6-23 (registration)Local registration function for the 'get-chain-id' tool, exported for use in the main server setup. Includes name, description, schema, and handler.
export function registerGetChainIdTools(server: FastMCP): void { server.addTool({ name: "get-chain-id", description: "Get the current chain id", parameters: z.object({}), execute: async () => { const result = getChainId(wagmiConfig) return { content: [ { type: "text", text: result.toString(), }, ], } }, }); }; - packages/metamask-mcp/src/index.ts:47-47 (registration)Calls the registerGetChainIdTools function to add the 'get-chain-id' tool to the main FastMCP server instance.
