Web Researcher MCP

Web Researcher MCP runs locally from a container image in an OCI registry such as Docker Hub or GitHub Container Registry: ghcr.io/zoharbabin/web-researcher-mcp:1.49.4. It speaks MCP over stdio, so the client starts it as a program and talks to it through standard input and output. It needs Docker or another OCI container runtime; started with docker run — the usual command is docker run -i --rm -e GOOGLE_CUSTOM_SEARCH_API_KEY -e GOOGLE_CUSTOM_SEARCH_ID -e SEARCH_PROVIDER -e SEARCH_ROUTING -e BRAVE_API_KEY -e SERPER_API_KEY -e SEARCHAPI_API_KEY -e SEARXNG_URL -e TAVILY_API_KEY -e EXA_API_KEY -e XQUIK_API_KEY -e EDGAR_CONTACT_EMAIL -e COURTLISTENER_API_TOKEN -e FRED_API_KEY ghcr.io/zoharbabin/web-researcher-mcp:1.49.4. It reads these environment variables: GOOGLE_CUSTOM_SEARCH_API_KEY (secret), GOOGLE_CUSTOM_SEARCH_ID, SEARCH_PROVIDER, SEARCH_ROUTING, BRAVE_API_KEY (secret), SERPER_API_KEY (secret), SEARCHAPI_API_KEY (secret), SEARXNG_URL, TAVILY_API_KEY (secret), EXA_API_KEY (secret), XQUIK_API_KEY (secret), EDGAR_CONTACT_EMAIL, COURTLISTENER_API_TOKEN (secret) and FRED_API_KEY (secret); set them in the client's configuration for this server.
