Best Graph 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.

MCP tools that search, write, and auto-link your Obsidian vault — and learn from your edits.
