"How to connect to a REST API" matching MCP connectors:
Matching Connector Tools:
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.
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.
Hosted MCP server to lint SKILL.md files: packaging checks, regex tests, JSON validation, diffs.
Format/lint JS, Python, HubL for automation platforms. Tools: format_code, format_json, ask_codefmt
Proves AI-generated Python does what you asked: lint, types, security, sandbox run, exact fixes.
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.
The official Svelte MCP server providing docs and autofixing tools for Svelte development
Statically audits MCP tool surfaces for token cost, schema quality, and design issues.
JSON/YAML, regex, diff, JWT, SQL dialects — the keyless millisecond ops an agent needs mid-task.
CVE lookups (NVD) and dependency-manifest audits (OSV) for AI agents. No API keys.
Honest library picks for coding agents in 25-360 tokens. Tells your agent what NOT to install.
Score the privilege a Chrome MV3 extension takes from its manifest, and diff permission sets.
Repository evidence for agents before they adopt dependencies, enter codebases, compare, or merge.
