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.
