MCPO
MCPO is a proxy that converts MCP servers into OpenAPI-compatible HTTP endpoints, allowing standard REST clients and LLM agents expecting OpenAPI interfaces to consume MCP tools without protocol-specific integration.
Best When
You want to bridge MCP tools into an existing OpenAPI ecosystem, especially Open WebUI, and need auto-generated /docs without writing any adapter code.
Avoid When
Your agents already support MCP natively, or you need advanced gateway features like rate limiting, RBAC, or observability.
Use Cases
- • Exposing stdio-based MCP tools as standard REST endpoints for Open WebUI or other LLM frontends
- • Making MCP tools accessible to any OpenAPI-compatible agent framework or tool
- • Running multiple MCP servers behind a single HTTP proxy with auto-generated interactive documentation
Not For
- • Native MCP clients that already speak the MCP protocol directly
- • Users who need aggregation logic, RBAC, or multi-tenancy beyond basic API key auth
- • Production deployments requiring high-availability or SLA guarantees
