Mempool MCP Server

Implementation Reference

• src/interface/controllers/AddressToolsController.ts:47-58 (handler)

  MCP tool handler registration for 'get-address-txs-chain', including input schema (address: string) and execution logic that delegates to AddressService.getAddressTxsChain and returns MCP-formatted response.

  private registerGetAddressTxsChainHandler(): void {
    this.server.tool(
      "get-address-txs-chain",
      "Returns chain transactions for an address",
      {
        address: z.string().describe("The address to get chain txs for"),
      },
      async ({ address }) => {
        const text = await this.addressService.getAddressTxsChain({ address });
        return { content: [{ type: "text", text }] };
      }
    );

• src/application/services/AddressService.ts:23-29 (helper)

  Helper method in AddressService that fetches chain transactions via request service and formats the response.

  async getAddressTxsChain({ address }: IAddressParameter): Promise<string> {
    const data = await this.requestService.getAddressTxsChain({ address });
    return formatResponse<IAddressTxResponse[]>(
      "Address Chain Transactions",
      data
    );
  }

• src/infrastructure/services/requests/AddressRequestService.ts:19-21 (helper)

  Core helper implementation: performs API request to retrieve chain transactions for the address.

  async getAddressTxsChain({ address }: { address: string }): Promise<IAddressTxResponse[] | null> {
    return this.client.makeRequest<IAddressTxResponse[]>(`address/${address}/txs/chain`);
  }
