"Managing Multiple MCP Servers" matching MCP connectors:

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.

DBRE-grade SQL analysis inside any MCP client. No connection. No install. Paste a query.

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.

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

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

Static linter for CLAUDE.md-style agent constitution files: 10 operational-guardrail checks.

Read-only AI coding tools for change verification, release readiness, capacity, and guidance.

Rams is a design reviewer for UI code. The MCP server puts the hosted engine inside a coding agent: the agent passes files to the review_files tool and gets back a 0–100 score with file:line issues and concrete fixes — accessibility, color, typography, spacing, components, UX, motion, craft, and native SwiftUI. Same engine and scoring as the Rams GitHub App. 258 rules, published at rams.ai/rules. Free tier: 30 reviews/month.

OSS libs in your stack, really used: source, tests, callers. C#, Java, TS, Python, Rust, PHP+.

Design review for UI code: 258 rules across 9 categories, scored 0-100 with concrete fixes.

Package intelligence for AI agents across npm, PyPI, crates.io and deps.dev. No API keys.

GitHub project health, package dependency risk, trending repos, license & package comparison.

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

Pre-flight check for AI coding agents: hallucinated packages + hardcoded secrets. Free, no account.

AI-native git hosting — repos, PRs, issues, CI gates, and AI code review over MCP (60 tools).

Runs your code against a contract; returns HELD or BROKE at the exact input. Deterministic.

Read-only, source-backed compatibility lookups and approved changes for ResolveMesh's catalog.

65+ free in-browser developer tools (JSON, Base64, JWT, hash, regex…) callable over MCP.

Multi-model code review: a panel of models + detectors return a pass/fail verdict. Paid via x402.

PQC scanner for GitHub repos and smart contracts. Detects quantum-vulnerable ECDSA/RSA.
