mcp-index SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
mcp-index from arasz/ai-badger is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add arasz/ai-badger/mcp-index@v0.1.0Pins v0.1.0 in mdr.lock. Pin the fingerprint instead.

Use when MCP tool selection needs help — the agent keeps picking the wrong tool, server tool definitions are bloating the prompt, or MCP servers were just added or removed. Manages .ai-badger/mcp-tools.json: tags, intent descriptions, and the hook that recommends tools per turn.
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 Index ## Prerequisites The index itself is JSON — no dependency needed to read, tag, intent, or list it. PyYAML is only needed to read a project's not-yet-migrated legacy `mcp-tools.yaml`: ```bash python3 -m pip install pyyaml # also in $AI_BADGER/engine/requirements.txt ``` Without it, a legacy-YAML-only project falls back to a stricter built-in parser and, if that can't safely read the file, refuses with a hint rather than a traceback (see `migrate` below). Manage `.ai-badger/mcp-tools.json` — a machine-readable index that maps every MCP server tool to tags (for filtering) and intent (for semantic matching). The index feeds the `ai_badger_hooks.py` plugin's `pre_llm_call` hook, which injects relevant tool recommendations into every LLM turn. ## Overview MCP servers expose 40+ tools per server. Agents scan ALL tool definitions in the system prompt, wasting tokens and sometimes picking the wrong tool (e.g., `search_text` when `search_in_files_by_text` is faster). The index solves this by: 1. **Tagging** each tool with category labels (`[build]`, `[database, sql]`, `[diagnostic]`) …

How to install
mdr add arasz/ai-badger/mcp-index@sha256:150a84060c432ee4The line at the top of this page pins the label v0.1.0, 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.
