Sevalla MCP Server
Give AI agents full access to the Sevalla PaaS API. Just 2 tools.
A remote Model Context Protocol server that exposes the entire Sevalla PaaS API through just 2 tools instead of ~200. AI agents write JavaScript that runs in sandboxed V8 isolates to discover and call any API endpoint on demand.
search- query the OpenAPI spec to discover endpoints, parameters, and schemasexecute- run JavaScript in a sandboxed V8 isolate that calls the API viasevalla.request()
This reduces context window usage by ~99% compared to traditional one-tool-per-endpoint approaches.
Background
Cloudflare came up with the Code Mode MCP pattern: instead of registering one tool per API endpoint, you give the agent two tools. One to search the API spec, one to execute code against it. Simple idea, massive difference in practice.
As a Cloudflare partner, we took this pattern and built it for the Sevalla PaaS API. The sandbox architecture and tool design are inspired by codemode, an open-source implementation of the same pattern.
