@mhdd_24/flyway-mcp

MCP server that runs Flyway repair + migrate across multiple database projects for QA or Development environments. Use it from Cursor, Claude Desktop, VS Code Copilot, or any MCP-compatible client.

Say "QA Flyway Migration" or "Dev Flyway Migration" in chat — the assistant calls the matching tool automatically.

Full documentation: docs/WIKI.md

How it works (30 seconds)

You (chat) → MCP client → flyway-mcp → discover projects under FLYWAY_ROOT
                                    → flyway repair + migrate (per project)
                                    → auto-remediate common errors → retry

1. Discovery — finds subfolders with flyway.toml and flyway_qa.toml / flyway_dev.toml

2. Repair — fixes schema history checksums before migrate

3. Migrate — applies pending migrations per environment config

4. Remediation — on failure, attempts automatic fixes (duplicate versions, placeholders, missing tables) and retries

Prerequisites

Expected project layout

Each project is a subfolder under FLYWAY_ROOT:

flyway-projects/
├── service-a-db/
│   ├── flyway.toml
│   ├── flyway_qa.toml
│   ├── flyway_dev.toml
│   └── migrations/
└── service-b-db/
    ├── flyway.toml
    └── migrations/

Install

Option A — npm (recommended)

npm install -g @mhdd_24/flyway-mcp

Option B — npx (no global install)

npx @mhdd_24/flyway-mcp

Option C — clone and build (contributors)

git clone https://github.com/Mhdd-24/Flyway-MCP.git
cd Flyway-MCP
npm install
npm run build
node dist/index.js

Configure your MCP client

Cursor

Edit Cursor Settings → MCP or ~/.cursor/mcp.json:

{
  "mcpServers": {
    "flyway": {
      "command": "npx",
      "args": ["-y", "@mhdd_24/flyway-mcp"],
      "env": {
        "FLYWAY_ROOT": "/path/to/your/flyway-projects",
        "FLYWAY_CLI": "flyway",
        "FLYWAY_MAX_RETRIES": "3"
      }
    }
  }
}

After global install:

"command": "flyway-mcp"

Local development:

"command": "node",
"args": ["C:/path/to/flyway-mcp/dist/index.js"]

Restart Cursor after saving.

Optional: limit projects

"FLYWAY_PROJECTS": "service-a-db,service-b-db"

Environment variables

Never commit database credentials. Keep connection strings in flyway_qa.toml / flyway_dev.toml inside each project (not in MCP env).

Optional parameters

Usage

Automatic remediation

On migration failure, the server may automatically:

Some errors (e.g. missing database plugins) cannot be auto-fixed and are reported in the summary.
