Implementation Reference
- index.js:733-735 (handler)Handler for get_block_info tool: extracts 'block' argument and makes API request to ChainFetch for block details.case 'get_block_info': const { block } = args; return await this.makeRequest(`/api/v1/ethereum/blocks/${block}`, 'GET', {}, null, token);
- index.js:368-381 (schema)Input schema definition for get_block_info tool, requiring a 'block' string parameter.{ name: 'get_block_info', description: 'Get detailed information about a specific block', inputSchema: { type: 'object', properties: { block: { type: 'string', description: 'The block number to get info for', }, }, required: ['block'], }, },
- index.js:368-381 (registration)Registration of get_block_info tool in the listTools response, including name, description, and schema.{ name: 'get_block_info', description: 'Get detailed information about a specific block', inputSchema: { type: 'object', properties: { block: { type: 'string', description: 'The block number to get info for', }, }, required: ['block'], }, },
- index.js:634-682 (helper)Shared helper method makeRequest used by get_block_info (and other tools) to perform authenticated API calls to ChainFetch endpoints.async makeRequest(endpoint, method = 'GET', params = {}, body = null, token = null) { const chainfetchToken = token || process.env.CHAINFETCH_API_TOKEN; if (!chainfetchToken) { throw new McpError( ErrorCode.InvalidRequest, 'CHAINFETCH_API_TOKEN is required' ); } const url = new URL(`${API_BASE_URL}${endpoint}`); // Add query parameters for GET requests if (method === 'GET' && Object.keys(params).length > 0) { Object.entries(params).forEach(([key, value]) => { if (value !== undefined && value !== null) { if (Array.isArray(value)) { value.forEach(v => url.searchParams.append(`${key}[]`, v)); } else { url.searchParams.append(key, value.toString()); } } }); } const fetchOptions = { method, headers: { 'Authorization': `Bearer ${chainfetchToken}`, 'Content-Type': 'application/json', }, }; if (body && method !== 'GET') { fetchOptions.body = JSON.stringify(body); } const response = await fetch(url.toString(), fetchOptions); if (!response.ok) { const errorText = await response.text(); throw new McpError( ErrorCode.InternalError, `API request failed: ${response.status} ${response.statusText} - ${errorText}` ); } return await response.json(); }
