Keycloak MCP Server
MCP server for Keycloak — the leading open-source Identity and Access Management (IAM) platform — enabling AI agents to manage Keycloak realms, users, roles, clients, and authentication flows. Allows agents to automate identity management tasks: creating users, assigning roles, configuring OAuth clients, managing realm settings, and querying authentication policies.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Admin access to identity infrastructure. Extremely sensitive credentials. Require human approval for any identity changes. Use minimal-scope service accounts. Self-hosted — your security responsibility.
⚡ Reliability
Best When
An organization running Keycloak for IAM wants AI agents to assist with user management, role configuration, and realm administration — particularly for automating repetitive identity management tasks.
Avoid When
You use commercial IAM providers (Okta, Auth0, Azure AD) — each has its own management API. Only relevant for Keycloak/Red Hat SSO deployments.
Use Cases
- • Managing Keycloak users and role assignments from user administration agents
- • Configuring OAuth clients and authentication flows from DevOps agents
- • Auditing realm security settings and user permissions from security assessment agents
- • Automating Keycloak configuration for new environments from infrastructure agents
- • Querying user authentication status from incident response agents
Not For
- • Teams using Auth0, Okta, or other commercial identity providers (different MCPs needed)
- • Production IAM changes without human review (identity changes have security implications)
- • Organizations not running Keycloak (requires self-hosted or Red Hat SSO)
Interface
Authentication
Keycloak admin credentials required (master realm admin or per-realm admin). Client credentials or username/password flow. Configure KEYCLOAK_URL, KEYCLOAK_REALM, admin credentials.
Pricing
Keycloak is free and open source (Apache 2.0). Red Hat SSO (commercial version) has subscription pricing. MCP server is free open source from sshaaf (Red Hat developer).

Known Gotchas
- ⚠ CRITICAL SECURITY: Identity changes (user creation, role assignment) have production security implications — require human review
- ⚠ Keycloak admin credentials have full realm control — use dedicated service accounts with minimal permissions
- ⚠ Keycloak REST API behavior varies between versions (18, 19, 20+) — test with your exact version
- ⚠ From sshaaf (Red Hat developer) — good quality with Red Hat Keycloak expertise
