Frequently Asked Questions
How do I connect Cartesia to my app?
Use Weavz Hosted Connect for API Key authentication. Install the SDK, create a connection through the connect portal or API, then execute tools programmatically.
What tools does Cartesia support?
Cartesia supports 6 tools including Synthesize Speech, Transcribe Audio, List Voices, Get Voice, Delete Voice, and more.
Can I use Cartesia with AI agents?
Yes. Add Cartesia to an MCP server in Tool Mode or Code Mode. Code Mode provides 3 meta-tools with on-demand API discovery so agents can compose stateful workflows without loading every action schema up front.
How do I connect Cartesia to ChatGPT or Claude?
Open the Weavz connector setup, sign in, choose a workspace, and add Cartesia as an approved app. ChatGPT, Claude, and other remote MCP clients can then call the scoped Cartesia tools exposed by that workspace.
Does Cartesia work with Claude Code, Cursor, Codex, and local agents?
Yes. Remote and local MCP clients can connect to a Weavz MCP endpoint for the workspace. Local coding agents can also use the Weavz CLI to inspect apps, discover actions, run approved Cartesia work, and execute Code Mode workflows from a terminal.
What can I ask an AI agent to do with Cartesia?
Cartesia exposes 6 tools, including Synthesize Speech, Transcribe Audio, List Voices, Get Voice, Delete Voice, and more. Use Weavz to keep credentials scoped, require approval for sensitive work, and audit what the agent did.
Can Cartesia be used in stateful agent workflows?
Yes. Agents can combine Cartesia tools with Filesystem, State KV, Human Gates, input partials, and other workspace integrations while keeping execution scoped to the selected workspace or end user.
What authentication does Cartesia use?
Cartesia uses API Key. Weavz stores credentials securely and uses them for authorized action execution.
