"A system like ChatGPT with memory to provide past query context in conversations" matching MCP connectors:

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.

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

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.

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

An MCP server that gives your AI access to the source code and docs of all public github repos

Post-quantum cryptography (PQC) vulnerability scanner. Detects ECDSA, RSA, AES-128 and other quantum-vulnerable algorithms in GitHub/GitLab/Bitbucket repos and Ethereum smart contracts. Returns risk score 0-100, CBOM (CycloneDX 1.6), and migration paths to NIST FIPS 203/204/205. Free tier: 10 scans/day, no key required.

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.

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

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

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

Screens public GitHub repos and PRs to generate risk maps, findings, and merge-readiness signals.

MCP gateway with 10 tools for code analysis, architecture, package audit & security.

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

Ship production-ready TypeScript code in half the time, at half the cost.

Pre-commit code quality guardian. Detects semantic drift in AI-generated code.

MCP server providing Pine Script v6 documentation. Enables AI to: Look up Pine Script functions and validate syntax Access official documentation for indicators, strategies, and visuals Understand Pine Script concepts (execution model, repainting, etc.) Generate correct v6 code with proper function references

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

The OpenZeppelin Cairo Contracts MCP server generates secure smart contracts in the Cairo language for Starknet environments based on OpenZeppelin templates. It brings OpenZeppelin's proven security and style rules directly into AI-driven development workflows to create safe, production-ready contracts. Key capabilities include providing templates for ERC-20, ERC-721, ERC-1155, Multisig, Governor, and Vesting contracts.
