Use Case Recommendations
Best for: CuratedMCP
CuratedMCP addresses a blind spot that appeared as soon as MCP took hold: servers are configured per-machine and per-client, which makes them invisible to any network-side AI gateway. CuratedMCP puts an open-source agent on the endpoint instead. One command discovers every MCP server configured across Claude Code, Claude Desktop, Cursor, Windsurf, GitHub Copilot and Gemini, flags the shadow servers nobody approved, and grades the machine A–F against a risk-classified catalog of over 70 human-reviewed servers — in roughly 60 seconds, entirely locally, with no configuration data leaving the machine and no account required. The scan exits non-zero on high-risk findings, which makes it usable directly as a CI gate rather than only as a report. The same catalog is queryable from an AI client via CuratedMCP's own MCP server, so an agent can check a server's risk classification before installing it. The Hub component installs a server once and syncs it across every client, replacing the per-client config sprawl that causes shadow servers in the first place. Two further components are in earlier stages: Sentinel, a local policy guard in early access, and TokenShield, a measured token ledger in beta. The product is MIT licensed and free for individual developers; the commercial tier is fleet-wide visibility, an org allowlist pushed to every machine, and an audit log of MCP tool calls for engineering organisations.
Ideal use cases:
- •Teams or individuals who need one-command discovery of mcp servers across six ai clients
- •Teams or individuals who need a–f machine grade against a risk-classified catalog of 70+ reviewed servers
- •Teams or individuals who need runs locally; no config data leaves the machine, no account needed
- •Teams or individuals who need non-zero exit on high-risk findings for use as a ci gate
- •Anyone focused on mcp workflows
- •Anyone focused on security workflows
Best for: LangSmith
