Implementation Reference
- The tool handler function that executes the core logic: calls wagmi's getTransactionReceipt with the provided args and wagmiConfig, then returns the result as MCP text content using JSONStringify.
execute: async (args) => { const result = await getTransactionReceipt(wagmiConfig, args); return { content: [ { type: "text", text: JSONStringify(result), }, ], }; }, - Tool schema including name, description, and Zod input parameters schema (hash: TransactionHash, optional chainId: number).
name: "get-transaction-receipt", description: "Fetch the Transaction Receipt given a Transaction hash.", parameters: z.object({ hash: TransactionHash.describe("A transaction hash."), chainId: z.coerce.number().optional().describe("The ID of chain to return the transaction receipt from."), }), - src/tools/get-transaction-receipt.ts:8-28 (registration)The registration function that defines and adds the 'get-transaction-receipt' tool to the FastMCP server.
