Why switch from Smithery?
Use 0mcp when you need a hosted MCP layer built from your own API spec, with deployment, versioning, and operational visibility in one workflow.
Detailed one-on-one comparisons to help you choose the best way to turn existing APIs into governed, hosted MCP servers.
Use 0mcp when you need a hosted MCP layer built from your own API spec, with deployment, versioning, and operational visibility in one workflow.
0mcp focuses on turning existing APIs into hosted MCP servers, so teams can expose agent-ready capabilities without shifting their whole SDK workflow.

Choose 0mcp when the priority is a managed MCP surface for AI clients, not only generating language SDKs around an API contract.
0mcp gives API teams a spec-first MCP path with hosted infrastructure, playground testing, and controls for what agents can call.
0mcp is built for teams that want conversion plus the surrounding product layer: hosted servers, revisions, analytics, and client-ready access.
Use 0mcp when you want to add an MCP interface alongside your API gateway strategy without turning MCP into a platform rebuild.
0mcp pairs API-to-MCP generation with practical hosting, playground validation, and usage signals for production-facing teams.
0mcp is a narrower, API-first fit when your goal is to expose product APIs to AI agents rather than manage a broader AI platform.
0mcp gives builders a focused route from OpenAPI specs to governed hosted MCP servers, with the API remaining the source of truth.
0mcp is for teams that already have APIs and want production MCP infrastructure, not a no-code app builder as the center of gravity.
FastMCP is useful for code-first MCP projects; 0mcp is the managed path when you want to start from an API spec and host the result.
0mcp keeps the workflow centered on API teams: import a spec, shape capabilities, deploy an MCP server, and monitor usage.
Use 0mcp when the job is agent-facing API access through MCP, not building automation workflows across many connected apps.
0mcp is a strong fit when you need a hosted MCP server for your API with controlled capability exposure and production feedback loops.
0mcp goes beyond generating an MCP shape by adding hosted deployment, playground testing, revisions, and usage analytics.
0mcp is the better fit when conversion is only step one and you also need a managed, customer-ready MCP server.
Create your workspace to import an API spec, test capabilities, and deploy a hosted MCP endpoint.
