Prefect Horizon
What is Prefect Horizon?
Prefect Horizon is an enterprise platform for deploying, cataloging, and governing Model Context Protocol (MCP) servers. It provides an MCP gateway that controls agent access to MCP tools through identity-based policies, authentication, and audit logging.
Key Capabilities
- MCP Server Deployment: Builds, containerizes, and deploys MCP servers from connected source-code repositories.
- MCP Server Registry: Maintains a catalog of internal and third-party MCP servers with ownership, version, and approval-status information.
- MCP Gateway: Routes MCP client requests to available tools and enforces access policies for tool calls.
- Identity Integration: Integrates with identity providers through SAML, OpenID Connect (OIDC), OAuth, SCIM, and directory synchronization.
- Access Controls: Supports OAuth 2.1 authentication and role-based access control (RBAC) at the tool level.
- Audit Logging: Records access and policy events for MCP-server and MCP-tool usage.
- Tool Composition: Combines tools from multiple MCP servers into a governed endpoint for a specific team or use case.
- Protocol Compatibility: Supports MCP-compliant clients, including Claude, Cursor, Visual Studio Code, Amazon Bedrock, and OpenAI agent tooling.
Audience & Use Cases
- Audience: Platform engineers, AI engineers, security teams, and IT administrators responsible for internal AI-agent infrastructure.
- Use Case: Deploying MCP servers, discovering approved tool endpoints, limiting agent permissions, and auditing agent access to MCP tools.
