Implementation Reference

• src/local/index.js:127-160 (registration)

  Registers the 'transaction' tool using server.tool, including inline schema and handler function.

  server.tool(
    "transaction",
    { transactionId: z.string() },
    async ({ transactionId }) => {
      try {
        const metadataResponse = await fetch(
          `https://arweave.net/tx/${transactionId}`
        );
        const metadata = await metadataResponse.json();
        const dataResponse = await fetch(
          `https://arweave.net/raw/${transactionId}`
        );
        const data = await dataResponse.text();
        const transactionInfo = {
          id: metadata.id,
          owner: metadata.owner,
          recipient: metadata.target,
          quantity: metadata.quantity,
          fee: metadata.reward,
          data_size: metadata.data_size,
          data: data.substring(0, 1e3),
          tags: metadata.tags || [],
        };
        return {
          content: [{ type: "text", text: cleanOutput(transactionInfo) }],
        };
      } catch (error) {
        return {
          content: [
            { type: "text", text: `Error: ${error?.message || String(error)}` },
          ],
        };
      }
    }

• src/local/index.js:129-129 (schema)

  Input schema for the 'transaction' tool, requiring a transactionId string.

  { transactionId: z.string() },

• src/local/index.js:130-160 (handler)

  Handler fetches Arweave transaction metadata and raw data, constructs transactionInfo object, and returns formatted content or error.

  async ({ transactionId }) => {
    try {
      const metadataResponse = await fetch(
        `https://arweave.net/tx/${transactionId}`
      );
      const metadata = await metadataResponse.json();
      const dataResponse = await fetch(
        `https://arweave.net/raw/${transactionId}`
      );
      const data = await dataResponse.text();
      const transactionInfo = {
        id: metadata.id,
        owner: metadata.owner,
        recipient: metadata.target,
        quantity: metadata.quantity,
        fee: metadata.reward,
        data_size: metadata.data_size,
        data: data.substring(0, 1e3),
        tags: metadata.tags || [],
      };
      return {
        content: [{ type: "text", text: cleanOutput(transactionInfo) }],
      };
    } catch (error) {
      return {
        content: [
          { type: "text", text: `Error: ${error?.message || String(error)}` },
        ],
      };
    }
  }
