Implementation Reference
- src/index.ts:194-224 (handler)The handler for the 'decodeTransactionData' tool. It performs a POST request to the Safe API's data-decoder endpoint with the transaction data (and optional 'to' address), handles specific HTTP errors, and returns the decoded transaction data as a JSON string.
case "decodeTransactionData": { const { data, to } = args as any; const response = await fetch(`${SAFE_API_URL}/data-decoder/`, { method: "POST", headers: { "Content-Type": "application/json" }, body: JSON.stringify({ data, to }), }); if (!response.ok) { if (response.status === 404) { throw new McpError( ErrorCode.InternalError, "Cannot find function selector" ); } if (response.status === 422) { throw new McpError(ErrorCode.InvalidParams, "Invalid data"); } throw new McpError( ErrorCode.InternalError, `Decoder API error: ${response.statusText}` ); } const decodedData = await response.json(); return { content: [ { type: "text", text: JSON.stringify(decodedData, null, 2) }, ], }; } - src/index.ts:143-160 (registration)Tool registration in the ListTools response, defining the name, description, and input schema for 'decodeTransactionData'.
