"A lightweight, self-hosted Git service" 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.

14 hosted MCP servers with free tiers: code review, time ops, data, business ops, education, more.

Hosted MCP server to lint SKILL.md files: packaging checks, regex tests, JSON validation, diffs.

Hosted MCP server for structured code review passes on human- and AI-written code. Free tier.

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.

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

Design review for UI code: 291 rules, scored 0-100 with fixes and git-applyable patches.

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.

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

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

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

Stop your AI agents from writing sloppy TypeScript. A toolkit that teaches coding agents like Claude Code, Codex, Cursor, Amp, and more to ship production-ready code in half the time, at half the cost. Docs are available at https://convention.sh/docs

Code intelligence for LLMs. Analyze, search, and retrieve code from any public git repository.

Send a coupling matrix, get zone classifications and optimal factorization strategy.

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

Ask a codebase what calls what: search, blast radius, paths between symbols, and diffs.

Give your AI agent a persistent map of your project's structure, dependencies, and bugs.

Enterprise code intelligence for M&A, security audits, and tech debt. Hosted server with 200k free.
