Read-only sensor that detects MCP tool-poisoning / rug-pull attacks: alerts when a trusted tool's schema or description changes silently.
mcp-schema-sentinel is an MCP server entry in ChatHome Skills, sourced from GitHub MCP Search and scored 34/100. Read-only sensor that detects MCP tool-poisoning / rug-pull attacks: alerts when a trusted tool's schema or description changes silently. As a Model Context Protocol server, it exposes tools that MCP-compatible LLM clients such as Claude, Cursor, and Copilot can call directly, extending an agent's reach beyond its built-in capabilities. ChatHome Skills discovered this entry through its daily ingest of official registries and GitHub discovery queries, and re-verifies repository facts, freshness signals, and install metadata on every run. The quality score weighs official-registry presence, a working install command, license clarity, GitHub star trajectory, and repository freshness — the full formula is on the Sources page. The install command above is ready to copy. Review the last-pushed date and repository status before adding mcp-schema-sentinel to a production agent workflow; the snapshot facts below are point-in-time values from the most recent ingest.
