How to Use the ElevenLabs MCP in Pydantic AI

Q: How do I set up ElevenLabs with Pydantic AI?

Install the package and initialize MCPToolset with your Vinkius HTTP endpoint. Pass the toolset instance into your Agent's toolsets parameter to expose all twelve tools.

Q: Does Pydantic AI validate ElevenLabs API responses?

Yes, the framework intercepts responses from tools like getvoicesettings and validates them against runtime schemas. This ensures your agent never processes corrupt voice configurations.

Q: How does Pydantic AI handle ElevenLabs voice cloning?

Your agent uses getvoice to load a target voice and verify its parameters. You can delete outdated clones by calling deletevoice within a validated workflow.

Q: How does the ElevenLabs MCP Server secure subscription and account data?

Subscription limits and account profiles retrieved via getsubscriptioninfo are processed over encrypted HTTPS channels. Vinkius runs the MCP server in an isolated container that discards session data immediately after execution.

Type-safe voice generation with Pydantic AI

The `text_to_speech` tool converts text into audio while the framework validates the output payload against strict Pydantic models. If the server returns unexpected metadata, your application raises a validation error immediately rather than corrupting your downstream audio players. This strict verification ensures that your runtime code only processes valid audio assets. You define the exact output schema, and the framework guarantees compliance before any playback begins.

Schema-validated ElevenLabs MCP Server voice inventory

The `list_voices` tool on this MCP server returns available neural profiles directly into structured Python models for instant type checking. Your code inspects voice details using `get_voice` to ensure the selected voice matches your application's required gender, language, and age attributes. That's what keeps your agent from hallucinating voice IDs or passing malformed parameters to the generation engine. Any unexpected change in the voice configuration schema is caught at the API boundary.

Safe account and subscription auditing

The `get_subscription_info` tool fetches your current character usage metrics and returns them as typed Pydantic objects. Your agent parses this data alongside `get_account_info` to programmatically monitor your remaining quota. If your subscription tier changes, the runtime validates the new limits against your configuration schemas. This prevents silent failures when your application hits character caps during heavy generation runs.

Setup guide

Set up ElevenLabs MCP in Pydantic AI

Prerequisites

Python 3.10+ installed
pydantic-ai-slim[fastmcp] package
Active Vinkius subscription with a valid endpoint token

1

Install Pydantic AI with FastMCP
Run pip install "pydantic-ai-slim[fastmcp]". The FastMCP toolset replaces the deprecated MCPServerHTTP class with full protocol support.
2

Configure the FastMCPToolset
Pass a JSON-style config dict to FastMCPToolset with your Vinkius URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports Streamable HTTP, SSE, and Stdio transports.
3

Create and run your agent
Pass the toolset to Agent(toolsets=[toolset]) and call agent.run(). Swap openai:gpt-4o for any supported model — Anthropic, Google, Mistral, or Groq.

agent.py

from pydantic_ai import Agent
from pydantic_ai.toolsets.fastmcp import FastMCPToolset

toolset = FastMCPToolset({
    "mcpServers": {
        "elevenlabs-alternative-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

agent = Agent(
    "openai:gpt-4o",
    toolsets=[toolset],
    system_prompt="You have access to ElevenLabs tools.",
)

result = await agent.run("List recent ElevenLabs transactions")
print(result.output)
