Implementation Reference
- src/serper_mcp_server/core.py:14-19 (handler)Handler function that implements the core logic for google_search_lens: extracts 'lens' from tool name to call Serper API at https://google.serper.dev/lens with the request payload.async def google(tool: SerperTools, request: BaseModel) -> Dict[str, Any]: uri_path = tool.value.split("_")[-1] url = f"https://google.serper.dev/{uri_path}" return await fetch_json(url, request)
- Pydantic model defining the input schema for the google_search_lens tool.class LensRequest(BaseModel): url: str = Field(..., description="The url to search") gl: Optional[str] = Field( None, description="The country to search in, e.g. us, uk, ca, au, etc." ) hl: Optional[str] = Field( None, description="The language to search in, e.g. en, es, fr, de, etc." )
- src/serper_mcp_server/server.py:25-38 (registration)Mapping dictionary that registers google_search_lens to its LensRequest schema, used for input validation and tool listing.google_request_map = { SerperTools.GOOGLE_SEARCH: SearchRequest, SerperTools.GOOGLE_SEARCH_IMAGES: SearchRequest, SerperTools.GOOGLE_SEARCH_VIDEOS: SearchRequest, SerperTools.GOOGLE_SEARCH_PLACES: AutocorrectRequest, SerperTools.GOOGLE_SEARCH_MAPS: MapsRequest, SerperTools.GOOGLE_SEARCH_REVIEWS: ReviewsRequest, SerperTools.GOOGLE_SEARCH_NEWS: SearchRequest, SerperTools.GOOGLE_SEARCH_SHOPPING: ShoppingRequest, SerperTools.GOOGLE_SEARCH_LENS: LensRequest, SerperTools.GOOGLE_SEARCH_SCHOLAR: AutocorrectRequest, SerperTools.GOOGLE_SEARCH_PATENTS: PatentsRequest, SerperTools.GOOGLE_SEARCH_AUTOCOMPLETE: AutocorrectRequest, }
- src/serper_mcp_server/server.py:41-60 (registration)MCP list_tools handler that registers the google_search_lens tool with its name, description, and input schema from the mapping.@server.list_tools() async def list_tools() -> List[Tool]: tools = [] for k, v in google_request_map.items(): tools.append( Tool( name=k.value, description="Search Google for results", inputSchema=v.model_json_schema(), ), ) tools.append(Tool( name=SerperTools.WEBPAGE_SCRAPE, description="Scrape webpage by url", inputSchema=WebpageRequest.model_json_schema(), )) return tools
- src/serper_mcp_server/core.py:25-40 (helper)Utility function that performs the HTTP POST request to Serper API with API key, handling SSL and timeout for google_search_lens results.async def fetch_json(url: str, request: BaseModel) -> Dict[str, Any]: payload = request.model_dump(exclude_none=True) headers = { 'X-API-KEY': SERPER_API_KEY, 'Content-Type': 'application/json' } ssl_context = ssl.create_default_context(cafile=certifi.where()) connector = aiohttp.TCPConnector(ssl=ssl_context) timeout = aiohttp.ClientTimeout(total=AIOHTTP_TIMEOUT) async with aiohttp.ClientSession(connector=connector, timeout=timeout) as session: async with session.post(url, headers=headers, json=payload) as response: response.raise_for_status() return await response.json()
