Discovers MCP servers and reads tool schemas before calling MCP tools. Use for: mcp tools, MCP schema, discover MCP, which MCP tool.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# MCP Tool Scout ## When to Use - User says **mcp tools** or task matches this capability - User says **MCP schema** or task matches this capability - User says **discover MCP** or task matches this capability - User says **which MCP tool** or task matches this capability ## Workflow 1. List MCP server folders (e.g. mcps/<server>/tools/*.json). 2. Match user task keywords to available tool names and descriptions. 3. Read full inputSchema for chosen tool before any CallMcpTool. 4. Report missing auth or server instructions; do not guess parameters. 5. Prefer least-privilege tool selection. ## Integrations - `tool-discovery-engine` - `defensive-mcp-audit` - `hitl-approver` ## Error Handling | Failure | Response | |---------|----------| | Schema missing | Stop; do not call tool without reading descriptor. | | Auth required | Ask user to complete auth out-of-band; never embed secrets in skill. | ## Gotchas - Mandatory schema read prevents parameter injection mistakes. ## Safety & Ethics (Publication-Ready) This skill is designed for public distribution. Constraints: - Read-only discovery; no MCP calls without user task context. …

How to install
mdr add stijnman/grok-custom-skills/mcp-tool-scout@sha256:cb7eb26312c95fdaThe line at the top of this page pins the label v1.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
