Let your AI agent turn text into audio
Voxi.fm ships an MCP server, so agents like Claude Code, Claude Desktop and Cursor can generate natural-sounding audio directly — no browser, no copy-paste. Ask your agent to narrate a draft and the MP3 lands in your Voxi.fm library.

The Model Context Protocol is an open standard for connecting AI agents to external tools. A Voxi.fm API key plus one config line gives your agent a set of audio tools it can call on its own — the agent decides when to list voices, start a generation, and check whether it finished.

What is MCP?
The Model Context Protocol is an open standard for connecting AI agents to external tools. Once an agent speaks MCP, it can call any MCP server — including Voxi.fm — without custom integration code.
Which agents can use the Voxi.fm MCP server?
Any MCP client that supports the Streamable HTTP transport, including Claude Code, Claude Desktop, Cursor, and custom agents built on the MCP SDKs.
What does it cost?
The same as generating audio in the app: 1 credit per article. New accounts get 5 free credits, and paid plans start low. There is no extra charge for agent access.
How long does a generation take?
Generation is asynchronous. generate_audio returns an audio id immediately; the agent polls get_audio_status until the MP3 URL appears, typically after 1–5 minutes depending on article length.
Is it safe to give an agent an API key?
A key can only generate and read audio for your own account — it cannot change billing or delete your data. Keys are stored hashed, never in plaintext, and you can revoke one at any time from the Agent Access page.
Where does the generated audio end up?
In your normal Voxi.fm library, alongside audio created in the app. You get the same MP3, embed player, and podcast options.
