  Handler function for the 'search-docs' tool. Connects to the Pinecone docs MCP server and calls its 'get_context' tool.

  server.tool('search-docs', INSTRUCTIONS, SCHEMA, async ({query}) => {
    const httpTransport = new StreamableHTTPClientTransport(new URL(DOCS_MCP_URL));
  
    const client = new Client({
      name: 'pinecone-docs',
      version: PINECONE_MCP_VERSION,
    });
  
    await client.connect(httpTransport);
  
    return (await client.callTool({
      name: 'get_context',
      arguments: {query},
    })) as SearchDocsResult;
  });

• src/tools/docs/search-docs.ts:8-12 (schema)

  Instructions and Zod input schema for the 'search-docs' tool.

  const INSTRUCTIONS = 'Search Pinecone documentation for relevant information';
  
  const SCHEMA = {
    query: z.string().describe('The text to search for.'),
  };

• src/tools/docs/search-docs.ts:21-37 (registration)

  Registration of the 'search-docs' tool via the addSearchDocsTool helper function called from docs/index.ts and ultimately from src/server.ts.

  export function addSearchDocsTool(server: McpServer) {
    server.tool('search-docs', INSTRUCTIONS, SCHEMA, async ({query}) => {
      const httpTransport = new StreamableHTTPClientTransport(new URL(DOCS_MCP_URL));
  
      const client = new Client({
        name: 'pinecone-docs',
        version: PINECONE_MCP_VERSION,
      });
  
      await client.connect(httpTransport);
  
      return (await client.callTool({
        name: 'get_context',
        arguments: {query},
      })) as SearchDocsResult;
    });
  }

• src/tools/docs/index.ts:4-6 (helper)

  Helper function addDocsTools that calls addSearchDocsTool to register the tool.

  export default async function addDocsTools(server: McpServer) {
    addSearchDocsTool(server);
  }

• src/server.ts:45-46 (registration)

  Top-level call to addDocsTools during server setup, which triggers the tool registration.
