"A tool or information about Playwright" matching MCP connectors:

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.

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.

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.

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

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.

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.

Pre-flight MCP security. Blocks compromised deps + tool drift. HMAC-signed. Dredd judges.

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

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.

Live PR/MR code reviews via review_url_code. OAuth or portal Bearer auth.

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