Scan code for quantum-vulnerable cryptography and get NIST post-quantum migration guidance.

Hosted, OAuth-gated endpoint for quantakrypto's post-quantum crypto tools: scan code for quantum-vulnerable cryptography (RSA/ECDH/ECDSA/DH) and get NIST ML-KEM/ML-DSA/SLH-DSA migration guidance over authenticated HTTP — nothing to install. Sign-in required (Google/GitHub/email). Same tools as the open-source @quantakrypto/mcp server; source at github.com/quantakrypto/pqc-tools.

Scan GitHub-hosted AI skills for vulnerabilities: prompt injection, malware, OWASP LLM Top 10.

Check that your AI is being logical. Free tool that mathematically catches contradictions in agent reasoning. No account needed. Also offers paid guardrails that converts natural language to formal verification proofs, that anyone can check succinctly.

Check if a dependency's license obligates you, based on how you ship. npm, PyPI, Go.

The official Svelte MCP server providing docs and autofixing tools for Svelte development

Lint a SKILL.md for frontmatter, structure, secrets and size. All 6 tools free.

Risk-scan a diff, flag AI-generated-code tells, find secrets. 5 of 7 tools need no account.

Format/lint JS, Python, HubL for automation platforms. Tools: format_code, format_json, ask_codefmt

A skeptical senior-engineer code reviewer over MCP: risk-scans unified diffs, flags AI-generated-code tells, reports complexity hotspots, scans for leaked secrets, and runs an OWASP security pass — real analyzers, no external APIs. Free tier, no signup.

A fully free linter for agent skill files: lint_skill validates YAML frontmatter, structure, size budgets, and safety phrasing with a pass/fail verdict; packaging_check validates zip layout against marketplace rules; plus regex_test, json_validate, diff_texts, and cron_explain for skill authors. No license or account required.

Honest library picks for coding agents in 25-360 tokens. Tells your agent what NOT to install.

Statically audits MCP tool surfaces for token cost, schema quality, and design issues.

Security + bug + perf + refactor audit for Python. Returns 0-10 score + MD report.

The official e18e MCP server keeping your agent in check from installing bloated dependencies.

CVE lookups (NVD) and dependency-manifest audits (OSV) for AI agents. No API keys.

Score the privilege a Chrome MV3 extension takes from its manifest, and diff permission sets.

Ground-truth code graph for your codebase: exact callers, callees, symbols & dependencies.

Packagephobia MCP — install-size analysis for npm packages

Repository evidence for agents before they adopt dependencies, enter codebases, compare, or merge.
