delimit-mcp-server

Overview

Delimit MCP server provides governance for AI-written code across Claude Code, Codex, Cursor, and Gemini CLI. It offers breaking-change detection, deploy gates, and multi-model consensus, delivering signed, replayable attestations for every AI coding operation. The server wraps any AI coding assistant with a governance chain that runs policy checks, records changes, and creates verifiable receipts. It operates as an MCP server, CLI tool, and GitHub Action, providing comprehensive control over AI-assisted development workflows.

FAQ

What AI assistants does Delimit support?

Delimit supports Claude Code, Codex, Cursor, and Gemini CLI, with cross-agent handoff capabilities between them.

How does the attestation system work?

Delimit creates HMAC-SHA256 signed attestations containing repo state before/after, changed files, gate results, and replay URLs for verification.

Can Delimit enforce policies or is it advisory only?

Delimit operates in advisory mode by default but can be configured to enforce policies with the --enforce flag that blocks CI on policy violations.
