ontomcp-driver from mareasw/ontoskills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add mareasw/ontoskills/ontomcp-driver@git:20260428.35e38bfPins git:20260428.35e38bf in mdr.lock. Pin the fingerprint instead.

Use OntoSkills MCP tools to discover and apply structured skill knowledge.
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
## Tools - **prefetch_knowledge** — One call: search + fetch context + compact. **Use this first.** - **search** — Find skills by keyword, alias, or structured filters. - **get_skill_context** — Full skill context with knowledge nodes (procedures, constraints, anti-patterns). - **evaluate_execution_plan** — Validate a multi-skill plan against state chains. - **query_epistemic_rules** — Cross-skill knowledge rules filtered by kind/severity. Responses are compact by default. Use `format: "raw"` for full JSON. ## Workflow 1. Call `prefetch_knowledge` with a query describing the task goal. 2. Read the returned knowledge nodes — they contain procedures, constraints, and anti-patterns. 3. For multi-skill plans: call `evaluate_execution_plan` to validate state chains. 4. Write code following the knowledge nodes. ## Critical rules - **Always prefetch first** — don't guess skill names. - **CRITICAL/HIGH severity nodes are hard constraints** — never skip them. - **Check requiresState** — skills fail without their preconditions. ## State semantics Skills form a state machine: `requiresState` (preconditions) / `yieldsState` (outcomes). …

How to install
mdr add mareasw/ontoskills/ontomcp-driver@sha256:537aa2fe4445d77dThe line at the top of this page pins the label git:20260428.35e38bf, 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.
