Cartesia AI for your agents.
Connect Cartesia AI once and every agent you run inside Even (Claude Code, Codex, OpenCode, Even Agents) can use it: 6 curated tools, discovered on demand, with your key stored on your machine and every call going direct to Cartesia AI.
What agents can do with Cartesia AI
Curated for agents: the calls that matter, with schemas and descriptions written for tool use, not an endpoint dump.

cartesia_list_voicesList available voices for speech synthesis.
