Best Code Intelligence AI Skills & MCP Servers

Your AI agent has read your codebase but still can't safely change it. unerr is a local guardrail that hands the agent the call graph and your rules at the moment it edits.

OpenCodeHub — stdio MCP server exposing code-graph + group tools

CLI/MCP tool providing TypeScript code intelligence via the TypeScript Language Service. Analyze exports, imports, resolve symbols, and check type errors.

MCP server for RepoMap — code intelligence via AST-based repository analysis

Repo memory for coding agents. Local-first MCP for Claude Code, Cursor, Windsurf, and Codex CLI: symbol graph, blast radius, diff-aware review, and git-pinned decisions. MIT; no API keys or code upload.

Code intelligence toolkit for AI agents — extract functions, trace call chains, find callers, detect dead code without reading entire files. Works as MCP server, CLI, or agent skill. Supports JS/TS, Python, Go, Rust, Java.
