Implementation Reference
- mcp_simple_tool/server.py:8-39 (handler)Core implementation of the mcp_fetch tool: asynchronously fetches website content using httpx, handles errors, and returns TextContent.async def fetch_website( url: str, ) -> list[types.TextContent | types.ImageContent | types.EmbeddedResource]: headers = { "User-Agent": "MCP Test Server (github.com/modelcontextprotocol/python-sdk)" } try: timeout = httpx.Timeout(10.0, connect=5.0) async with httpx.AsyncClient( follow_redirects=True, headers=headers, timeout=timeout ) as client: response = await client.get(url) response.raise_for_status() return [types.TextContent(type="text", text=response.text)] except httpx.TimeoutException: return [types.TextContent( type="text", text="Error: Request timed out while trying to fetch the website." )] except httpx.HTTPStatusError as e: return [types.TextContent( type="text", text=(f"Error: HTTP {e.response.status_code} " "error while fetching the website.") )] except Exception as e: return [types.TextContent( type="text", text=f"Error: Failed to fetch website: {str(e)}" )]
- mcp_simple_tool/server.py:72-78 (handler)Dispatch logic in the registered call_tool handler: validates 'url' argument and invokes fetch_website for mcp_fetch.if name == "mcp_fetch": if "url" not in arguments: return [types.TextContent( type="text", text="Error: Missing required argument 'url'" )] return await fetch_website(arguments["url"])
- mcp_simple_tool/server.py:95-108 (registration)Registers the mcp_fetch tool in list_tools(): defines name, description, and inputSchema.types.Tool( name="mcp_fetch", description="Fetches a website and returns its content", inputSchema={ "type": "object", "required": ["url"], "properties": { "url": { "type": "string", "description": "URL to fetch", } }, }, ),
- mcp_simple_tool/server.py:98-107 (schema)Input schema for mcp_fetch: object requiring 'url' string with description.inputSchema={ "type": "object", "required": ["url"], "properties": { "url": { "type": "string", "description": "URL to fetch", } }, },
