From the repository

- Java 21+ - Download from Adoptium
- Verify installation: java -version
- Should show Java 21 or higher
- Node.js 18+ - Download from nodejs.org
- Verify installation: node --version
- Should show v18.0.0 or higher

npm install -g @jakarta-migration/mcp-server

npx -y @jakarta-migration/mcp-server



See Local Setup (STDIO) below for client configuration.
For local development, use STDIO transport which works with Cursor, Claude Code, and Antigravity. This is the recommended approach for maximum privacy and performance.
Option 1: Global Install (Recommended)
Install the package globally for system-wide access:

bash
npm install -g @jakarta-migration/mcp-server

After installation: - The JAR file will be automatically downloaded from GitHub releases on first use - JAR is cached in your home directory for faster subsequent runs - You can use the command directly: jakarta-migration-mcp Option 2: npx (No Installation) Use npx to run without installing:

bash
npx -y @jakarta-migration/mcp-server



The -y flag automatically accepts the package download. The JAR will be downloaded and cached on first use.
Option 3: Local Development Build
If you're building from source or want to use a local JAR:

bash

export JAKARTA_MCP_JAR_PATH=/path/to/build/libs/jakarta-migration-mcp-1.0.0-SNAPSHOT.jar

$env:JAKARTA_MCP_JAR_PATH = "E:\Source\JakartaMigrationMCP\build\libs\jakarta-migration-mcp-1.0.0-SNAPSHOT.jar"

jakarta-migration-mcp --download-only

You should see: - Java version detection - JAR download or cache confirmation - No errors To use a custom JAR path or override transport, see NPM Installation Configuration. For local HTTP-based testing or development:

1. Build the project:

bash
./gradlew bootJar



2. Start server with Streamable HTTP:
Windows (PowerShell):

powershell
java -jar build\libs\jakarta-migration-mcp-1.0.0-SNAPSHOT.jar --spring.profiles.active=mcp-streamable-http



   Mac/Linux:

bash
java -jar build/libs/jakarta-migration-mcp-1.0.0-SNAPSHOT.jar \
--spring.profiles.active=mcp-streamable-http



   Or with SSE (legacy):
Windows (PowerShell):

powershell
java -jar build\libs\jakarta-migration-mcp-1.0.0-SNAPSHOT.jar --spring.profiles.active=mcp-sse



   Mac/Linux:

bash
java -jar build/libs/jakarta-migration-mcp-1.0.0-SNAPSHOT.jar \
--spring.profiles.active=mcp-sse



3. Test the endpoint:
Windows (PowerShell):

powershell

Once configured, you can use the MCP tools in your AI assistant:

`analyzeJakartaReadiness`

Comprehensive project analysis with readiness score

`detectBlockers`

Find dependencies and patterns that prevent migration

`recommendVersions`

Get Jakarta-compatible version recommendations

`createMigrationPlan`

Generate phased migration plan with risk assessment

`analyzeMigrationImpact`

Analyze full migration impact combining dependency analysis and source code scanning

`verifyRuntime`

Test migrated application execution

| Tool | Description |
|------|-------------|
| analyzeJakartaReadiness | Comprehensive project analysis with readiness score |
| detectBlockers | Find dependencies and patterns that prevent migration |
| recommendVersions | Get Jakarta-compatible version recommendations |
| createMigrationPlan | Generate phased migration plan with risk assessment |
| analyzeMigrationImpact | Analyze full migration impact combining dependency analysis and source code scanning |
| verifyRuntime | Test migrated application execution |

See MCP Tools Documentation for detailed tool descriptions and parameters.

1. Restart your IDE completely - MCP servers load on startup
2. Check MCP server status - Look for errors in IDE logs
3. Verify configuration - Ensure JSON syntax is correct
4. Check prerequisites - Java 21+ and Node.js 18+ must be installed

Claude Desktop / Cursor

Paste into your MCP client config file to install this server.
