Modelbound Mcp
A local-first MCP server that stores and syncs agent skills across Cursor, Claude, Kiro, Windsurf, VS Code, and Amazon Q. Exposes tools for validation, linting (front-matter, token counts, broken links), format conversion between IDE conventions, and diff operations. All core functions run offline over stdio with no API key required. Add MODELBOUND_API_KEY to unlock cloud sync, marketplace installs, and team resource trees grouped by platform hierarchy. Useful if you switch between AI coding tools frequently and don't want to rewrite rules and context files for each one. Also works as a standalone CLI for batch operations on skill directories.

Readme
modelbound-mcp
Local-first MCP server for agent skills. Validate, lint, diff, and convert agent skill files across Cursor, Claude, Codex, Kiro, Windsurf, VS Code, and Amazon Q — no account required. Optional cloud sync with ModelBound.
Why ModelBound?
AI tools come and go. You might use Cursor today, switch to Claude Code tomorrow, and try Kiro next week — but your skills, rules, and context shouldn't be locked into any one of them. ModelBound gives you a single place to store and manage your agent skills, so you can move between tools freely without rebuilding your setup each time. Write a skill once, sync it everywhere, and get more value out of every AI subscription you're already paying for.
