Scans an AI agent's instruction and tool-config files (CLAUDE.md, AGENTS.md, skills, slash commands, subagents, Cursor and Cline rules, hooks, MCP server configs) for prompt injection, hidden Unicode or HTML-comment instructions, exfiltration commands, and risky permissions or unpinned MCP packages, then recommends what to remove or quarantine. Use when the user installs third-party skills or plugins, clones an unfamiliar repo, adds an MCP server, or asks whether their agent setup is safe to…
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
# Prompt Injection Scanner Check the files an agent reads as instructions, and the configs that decide what it can run, before trusting them. ## 1. Scan ```bash python3 scripts/scan_agent_config.py # this project's agent files python3 scripts/scan_agent_config.py --user # + ~/.claude skills, commands, agents, settings, MCP servers python3 scripts/scan_agent_config.py --user --plugins # + installed plugins in ~/.claude/plugins/cache python3 scripts/scan_agent_config.py ~/Downloads/some-skill # just what you downloaded ``` Exit codes: `0` nothing at or above `--fail-on` (default `medium`) · `1` findings at or above it · `2` nothing to scan. Add `--json` for tooling and `--exclude GLOB` to skip paths. The script only reads text and parses JSON. It never runs, imports or sources what it scans, and it masks secret values in its output. …

How to install
mdr add milad-ahmd/agent-skills/prompt-injection-scanner@sha256:5120d7e8dff018c6The line at the top of this page pins the label git:20261029.e53e3bd, 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.
