# Security & Compliance Agent Plugins — page 3 of 3

Plugins for defending software: vulnerability scanning, dependency and supply-chain auditing, secrets detection, authentication and authorisation, threat modelling, privacy and regulatory compliance.

| Name | Description | Repo |
| --- | --- | --- |
| [protect-main-branch](https://agentpluginsdirectory.com/plugins/protect-main-branch) | Block direct commits and pushes to main or master. Enforced at commit time by reading the current branch, and at push time by parsing the refs the agent is pushing. | open-coder-ai/chock-catalog |
| [scan-secrets](https://agentpluginsdirectory.com/plugins/scan-secrets) | Blocks known credential patterns -- vendor key prefixes, private-key blocks, and key/token/password assignments -- at two enforcement points: at commit (the git hook, over staged changes) and at agent tool-use (the mcp-gateway / agent write guard, over a tool call's arguments), so a secret is caught as the agent writes it, before it ever reaches a commit. Matched by pattern, not by entropy analysis. Best-effort guard; not a replacement for a dedicated secret scanner. | open-coder-ai/chock-catalog |
| [verify-dependency-exists](https://agentpluginsdirectory.com/plugins/verify-dependency-exists) | Block hallucinated or unknown dependencies before they enter the repo. Watches requirements.txt, pyproject.toml, package.json, and go.mod, and blocks any newly added dependency not present in the allowlist file. Opt-in: disabled by default because it requires a curated allowlist. Enable with `chock enable verify-dependency-exists` after populating .chock/dependency-allowlist.txt. | open-coder-ai/chock-catalog |
