About
1MCP is a unified Model Context Protocol runtime for aggregating multiple MCP servers behind a single `1mcp serve` process. It supports static servers loaded at startup, template servers resolved from client or session context, and instruction aggregation to reduce the tool surface exposed to agents. The project also includes CLI mode for agent workflows such as `instructions`, `inspect`, and `run`, plus a stdio proxy for clients that need broader compatibility. It is intended for Claude Code, Cursor, Codex, and other MCP-capable agent clients that need a shared runtime with filtering, presets, and project context.
