Browse all Model Context Protocol servers with quality scores, stars, languages and maintenance activity.
vet-mcp checks open source packages—like those suggested by AI coding tools—for vulnerabilities and malicious code. It supports npm and PyPI, and runs locally via Docker or as a standalone binary for fast, automated vetting.
Exposes the RSigma Sigma detection-engineering toolkit to AI agents over stdio or Streamable HTTP with `rsigma mcp serve`. Tools to author, lint, validate, and convert Sigma detection rules, evaluate and explain detections against log events, and inspect correlation state, all backed by a native Rust engine.
[Mobb Vibe Shield](https://vibe.mobb.ai/) identifies and remediates vulnerabilities in both human and AI-written code, ensuring your applications remain secure without slowing development.
Embeds Snyk's security engines into agentic workflows. Secures AI-generated code in real-time and accelerates the fixing vulnerability backlogs.
MINT Protocol — universal work attestation for autonomous agents. Cryptographically attest, verify, rate, and discover agent work to build portable, on-chain trust and reputation across the agent economy. 6 tools.
Human-in-the-loop approval inbox for AI agents. An agent submits a proposed action (send email, post comment, run a command) via `impri_push_action`, a human approves, rejects, or edits it from a web, mobile, or Slack/Discord/Telegram inbox, and the agent only proceeds on an approved decision. The gate is a data dependency, not a prompt. Full audit trail, self-hostable (MIT, Docker Compose). `npx
Compliance and identity for AI agents — verify an agent's certificate scope, read its behavioral risk score, and append to an immutable audit trail. X.509 identity issued via AWS KMS; MiCA / EU AI Act aligned. `npx -y @kakunin/mcp`
SSRF-hardened web gateway MCP** — `web_fetch`, `web_search`, `metis_verify`; one audited security core for Metis, ARGUS, and the ecosystem. stdio + optional HTTP · Python · [Glama](https://glama.ai/mcp/servers/alexar76/aimarket-mcp) · Registry `io.github.alexar76/aimarket-mcp`.
Agent identity, scoped delegation, and governance: issue passports, build and verify narrowing-only delegation chains, enforce policy at a gateway, and emit signed admission and outcome records. 150 tools. `npx -y agent-passport-system-mcp`
ARGUS-3 as a stdio MCP server** (`argus mcp` → `argus_ask`, `argus_status`). **WARDEN** vets third-party MCP servers before any tool runs (LUMEN-scored firewall, tool-def pinning, drift sentinel). Distinct from `aimarket-oracle-gateway` (oracle tools) and `aimarket-plugins` (hub packager). npm `@alexar76/argus3` · [live](https://magic-ai-factory.com/argus/).
Official [Shieldly](https://www.shieldly.io) MCP server: `analyze_iam_policy` and `analyze_cloudformation_template` tools flag AWS IAM privilege-escalation paths, wildcards, and over-permissive access. Free demo mode, no signup or API key needed. `npx -y @shieldly/mcp`.
Check the reputation of an AI microservice or public API *before* calling it, and submit ratings afterward — from a free, open trust registry (no account or API key). Scores combine Bayesian reputation and EigenTrust, strengthened by cryptographically signed service receipts and a Merkle audit trail. Install: `npx -y @trustscoreagent/mcp-server`.
