RGB Lightning Network MCP Server

Instructions

Implementation Reference

• src/server.ts:137-150 (registration)

  Registration of the 'rgb_list_transactions' MCP tool with empty input schema and inline handler that lists on-chain transactions using rgbClient.listTransactions() and returns formatted JSON or error.

  server.tool(
    'rgb_list_transactions',
    'List on-chain transactions',
    {},
    async ({}) => {
      try {
        const transactions = await rgbClient.listTransactions();
        return { content: [{ type: 'text', text: JSON.stringify(transactions, null, 2) }] };
      } catch (error) {
        const errorMessage = error instanceof Error ? error.message : String(error);
        return { content: [{ type: 'text', text: `Error: ${errorMessage}` }], isError: true };
      }
    }
  );

• src/server.ts:141-149 (handler)

  Inline handler function executing the tool logic: calls rgbClient.listTransactions(), stringifies result as text content, handles errors.

  async ({}) => {
    try {
      const transactions = await rgbClient.listTransactions();
      return { content: [{ type: 'text', text: JSON.stringify(transactions, null, 2) }] };
    } catch (error) {
      const errorMessage = error instanceof Error ? error.message : String(error);
      return { content: [{ type: 'text', text: `Error: ${errorMessage}` }], isError: true };
    }
  }

• src/rgb-client.ts:73-75 (helper)

  Supporting method in RGBApiClientWrapper class that wraps and calls the underlying SDK client.onchain.listTransactions() method.

  async listTransactions() {
    return await this.client.onchain.listTransactions();
  }
