Key Features
- User JWT Token Authentication
- Comprehensive Keycloak Operations (users, realms, clients, roles, groups, etc.)
- SSE Transport for HTTP-based communication
- Production-ready OpenShift/Kubernetes deployment
- Multi-architecture container images
- GraalVM native image support
Quick Start
Using Docker
docker run -d \
--name keycloak-mcp-server \
-p 8080:8080 \
-e KC_URL=https://keycloak.example.com \
-e KC_REALM=master \
-e OIDC_CLIENT_ID=mcp-server \
quay.io/sshaaf/keycloak-mcp-server:latest
Authentication
Users authenticate with their own JWT tokens from Keycloak:
# Get your token
./scripts/get-mcp-token.sh \
--keycloak-url https://keycloak.example.com \
--username your-username \
--password your-password
Configure in your MCP client (~/.cursor/mcp.json):
{
"mcpServers": {
"keycloak": {
"transport": "sse",
"url": "https://mcp-server.example.com/mcp/sse",
"headers": {
"Authorization": "Bearer <your-jwt-token>"
}
}
}
}
