Koskamo

codemcp MCP

A vendor-neutral proxy for MCP that aggregates multiple servers into a single namespace, reducing token usage by starting with minimal tool definitions. It features a credential-isolating QuickJS sandbox for executing model-written code, governance rules for approvals, and supports clients like Claude Code, Cursor, and VS Code.
