As Decided MCP Server

Engineering decisions your agents can follow. Build, as decided. AsDecided keeps requirements, decisions, designs, roadmaps, and prompts as typed Markdown in your repository. Its native Rust engine validates that knowledge, retrieves relevant decisions deterministically, and serves it read-only to agents over MCP.

People who need documentation tools inside Claude, Cursor, VS Code, or another MCP client. The project is written in Rust.
