Questions

API and MCP, answered

Which AI assistants work with Caplia?+

Any client that speaks MCP over streamable HTTP, including Claude Desktop, Claude Code, Cursor, Codex and Windsurf. Founders can also add Caplia as a custom connector in Claude and ChatGPT using OAuth.

What's the difference between founder and venture keys?+

Founder keys (cap_fnd_) are scoped to your own company. Venture keys (cap_inv_) work across your team's pipeline, theses and views, with the same row-level permissions as the web app.

Can an agent change my data?+

Only with a write-scoped key. Read keys can only fetch data. Write keys can update profiles, upload documents and submit or publish decks.

Is there a sandbox?+

Yes. Test keys work on the sandbox hosts for the API and MCP, so you can build and test without touching live data.
