Onepin

Onepin MCP

Client configuration for the Onepin MCP server — a hosted, remote Model Context Protocol server that turns scripts into speech.

Endpoint	https://mcp.onepin.ai (Streamable HTTP)
Authentication	OAuth 2.0 — browser sign-in, no API key to copy
Registry entry	ai.onepin/onepin
Smithery listing	smithery.ai/servers/podonos/onepin
Documentation	https://docs.onepin.ai

An Onepin account is required. The server is hosted by Podonos; this repository contains only the client-side configuration, not the server implementation.

What it does

Onepin workflows are graphs of nodes that normalize text, synthesize audio, translate, and validate the result. Through MCP you can:

• Browse workflows and templates, and build a new workflow from a template or from intent
• Search voices and preview them before committing to one
• Run a workflow over a script and poll the run to completion
• Fetch the resulting audio, per line or as a download
• Check credit balance and usage

Runs are asynchronous: start one, then poll it. Every result is a plain audio file on a presigned URL.

Install

Cursor

Install from the Cursor Marketplace, or add the server manually:

{
  "mcpServers": {
    "onepin": {
      "url": "https://mcp.onepin.ai"
    }
  }
}

Gemini CLI

gemini extensions install https://github.com/podonos/onepin-mcp

Then authenticate when prompted, or run /mcp auth onepin.

Claude

Add https://mcp.onepin.ai as a custom connector.

Note that Onepin serves a second, reduced surface at https://mcp.onepin.ai/studio, covering everything up to the point audio is generated. It has its own OAuth resource identifier and is the URL used for directory submissions — see docs/surfaces.md. The full surface above is the one to add by hand.

Any other MCP client

Point the client at https://mcp.onepin.ai using the Streamable HTTP transport. The server advertises its authorization server via RFC 9728 (/.well-known/oauth-protected-resource), so clients that support OAuth discovery and dynamic client registration need no further configuration.

server.json is the entry published to the official MCP Registry as ai.onepin/onepin; CI publishes it when its version changes. The namespace proof behind that name — a TXT record on the onepin.ai apex — lives in the Onepin backend repository's Terraform, not here. See docs/mcp-registry.md.
