What your agent can do

Certta gives your agent 0 tools it calls directly — pick the ones it needs, in Claude, Cursor, or any MCP client.

Example call
// Your agent calls a tool directly — no glue code.
// CodeSpar's managed tier handles OAuth2, token rotation and rate limits.
const result = await session.call("list_resources", { /* ... */ });

Install

terminal
$ npm install @codespar/mcp-certta
