• packages/metamask-mcp/src/tools/get-token.ts:16-30 (handler)

  The execute function (handler) for the 'get-token' tool. Fetches token information using wagmi's getToken for the given address and optional chainId, then stringifies and returns the result.

  execute: async (args) => {
    const address = args.address as Address
    const chainId = args.chainId as typeof wagmiConfig['chains'][number]['id']
    const result = await getToken(wagmiConfig, {
      address,
      chainId,
    })
    return {
      content: [
        {
          type: "text",
          text: JSONStringify(result),
        },
      ],
    }

• packages/metamask-mcp/src/tools/get-token.ts:12-15 (schema)

  Zod schema defining input parameters: address (string) and optional chainId (number).

  parameters: z.object({
    address: z.string(),
    chainId: z.coerce.number().optional(),
  }),

• packages/metamask-mcp/src/tools/get-token.ts:9-32 (registration)

  Registers the 'get-token' tool on the FastMCP server, including name, description, parameters schema, and execute handler.

  server.addTool({
    name: "get-token",
    description: "Get the token information",
    parameters: z.object({
      address: z.string(),
      chainId: z.coerce.number().optional(),
    }),
    execute: async (args) => {
      const address = args.address as Address
      const chainId = args.chainId as typeof wagmiConfig['chains'][number]['id']
      const result = await getToken(wagmiConfig, {
        address,
        chainId,
      })
      return {
        content: [
          {
            type: "text",
            text: JSONStringify(result),
