### Description (declared)

# Safe Migrations MCP

**The safety layer the agent ecosystem needs.**

Stops Claude Code, Cursor, OpenClaw, and other AI coding agents from quietly breaking your database schema or config files.

Every proposed change is diffed, risk-flagged, and requires a fresh simulation-issued confirmation token before a single byte is written.

An MCP server that gives AI coding agents a safe, auditable, human-in-the-loop way to propose and execute DB schema changes **and** everyday config edits — the exact class of change that silently corrupts production when an agent gets overconfident.

---

## Why this exists

Agents are great at *proposing* changes and terrible at *understanding the
blast radius* of those changes. A one-word YAML typo, a helpful `DROP COLUMN`,
a missing `WHERE` in an `UPDATE` — any of these can take a project down while
the agent cheerfully reports success.

Safe Migrations MCP puts a mandatory checkpoint between the agent and your
disk:

1. **Propose** — agent sends an intent (natural language or raw SQL, or a
   new config file); server returns a `proposal_id` plus a redacted preview
   and SHA-256 hash of the SQL/edit and its rollback. Full payload is stored
   server-side, never echoed back.
2. **Simulate** — dry-run inside a rolled-back transaction; count affected
   rows; surface every DROP, TRUNCATE, NOT-NULL-without-default, secret-key
   removal, etc. On success, returns a one-time `confirmation_token` bound
   to the proposal's fingerprint.
3. **Apply** — only runs with that fresh `confirmation_token`. Snapshots
   the file or DB first. Logs everything to an append-only audit trail.

Local-first. Zero cloud dependency. ~2k LOC of Python, hardened against the usual footguns (symlink writes, silent SQLite creation, MySQL DDL auto-commit, token replay, secret leakage in diffs).

Born from watching an OpenClaw agent break its own config file trying to make a "small" change. The fix is universal: any agent that can edit anything should have to slow…
