Agents onboard themselves

No browser needed. The user only reads a 6-digit code from their email.

pip install renda
renda signup you@example.com     # emails a 6-digit code
renda verify 123456              # saves an API key
renda render robot.glb -o renders/

Or plug in the MCP server

Local stdio (uploads local files) or remote at /api/mcp. Tools: signup, verify, render, estimate, jobs, usage, billing.

Formats

Converted through a lightweight scene IR, so a .blend can render in Mitsuba and an STL can render in Cycles.
