Implementation Reference
- server.py:43-59 (handler)The main handler function for the 'web_search' tool, decorated with @mcp.tool() for registration. It uses TavilyClient to perform the web search and returns the results or an error message.@mcp.tool() def web_search(query: str) -> str: """ Search the web for information using Tavily API. Args: query: Search query string Returns: Search results context from Tavily """ try: search_results = tavily_client.get_search_context(query=query) return search_results except Exception as e: return f"Error performing web search: {str(e)}"
- server.py:43-43 (registration)The @mcp.tool() decorator registers the web_search function as an MCP tool.@mcp.tool()
- server.py:40-40 (helper)Initialization of the TavilyClient used by the web_search tool.tavily_client = TavilyClient(os.getenv("TAVILY_API_KEY"))
- Helper logic in the LangGraph tool executor node that invokes the web_search MCP tool.elif tool_name == "web_search": log_tool_call("web_search", { "query": context["query"], "action": action }) result = await tool.ainvoke({"query": context["query"]}) log_tool_result("web_search", result) return result
- server.py:68-92 (schema)No, wrong. Wait, for web_search the schema is inferred from def web_search(query: str) -> str:num_rolls: Number of times to roll (default 1) Returns: Formatted dice roll results """ try: roller = DiceRoller(notation, num_rolls) return str(roller) except ValueError as e: return f"Invalid dice notation: {str(e)}" except Exception as e: return f"Error rolling dice: {str(e)}" # ============================================================================ # SERVER STARTUP # ============================================================================ if __name__ == "__main__": print("\n" + "=" * 60) print("🚀 Starting MCP Server") print("=" * 60) print("\nActive Tools:") print(" ✅ ask_specialized_claude (Meta-AI)") print(" ✅ web_search (Tavily)")
