scan_mcp_server
shallowdev.fetchgate/fetchgate · Verify this server
Connect to a remote Streamable HTTP MCP server, fetch its tools/list (sends only initialize, notifications/initialized and tools/list — never tools/call) and scan every tool name, description, parameter description and the server's initialize `instructions` string for tool-poisoning patterns: hidden-instruction markers, invisible Unicode, directives aimed at the model, credential/secret references, exfiltration shapes and instructions about other tools. Returns per-tool findings with severity, excerpt and a score band. Use it before installing or trusting a third-party server. Heuristic: a clean result means nothing obvious in what the server declares about itself, not that it is safe. Wraps GET /v1/mcp-scan. Free, rate-limited per caller; private/internal-network hosts are rejected.
