🟢 8w | 2 |
| MyMCPTools | Tracks the health of remote MCP servers across a catalog of 2,467 entries: hourly handshake probes, uptime history, incident timelines, and tool-schema drift detection against the previous probe. Queryable over HTTP or as an MCP server itself. | |
🟢 0d | 2 |
| Junctio | Self-hosted MCP gateway that puts stdio, Docker and remote servers behind one endpoint per client, with API keys or a built-in OAuth authorization server downstream and proactive upstream OAuth refresh. | |
🟢 3d | 2 |
| Agent Guard | MCP security scanner and runtime governance gateway for AI agents. Detects tool poisoning, prompt injection, typosquatting, hidden unicode, and schema abuse in MCP tool definitions. Also provides policy enforcement, rate limiting, and kill switch. | |

| mcp-drift | Offline, read-only CLI that scans MCP client configs for unpinned npx/uvx and @latest launches, inline tokens, broad filesystem scope and drift from an approved baseline, with SARIF output. | |
🟢 3d | 0 |
| mcp-cassette | Records a real MCP session and replays it as an MCP server over stdio or Streamable HTTP for offline tests, gates tool-contract drift against a committed snapshot, and lints tool, prompt and resource descriptions and recorded tool results for prompt injection. | |
