Type-safe synthesis tools

Every response from `create_tts_job` is validated against your Pydantic models. If the API returns malformed data, your agent catches it immediately. This approach eliminates silent failures. You define the schema, the agent enforces it, and the synthesis pipeline remains stable even if the API changes.

Structured voice metadata

Use `get_speaker` to pull detailed speaker information that maps perfectly to your Python objects. You get full type safety for every field returned by the engine. `list_voices` returns a clean, validated list of options. Your agent filters these using standard Python logic, ensuring only authorized voices are used.

Reliable job status checks

The `get_tts_job` tool ensures your agent knows exactly when audio is ready. By checking the job status within your Pydantic-validated flow, you avoid handling incomplete audio URLs. This keeps your agent's decision-making robust. It won't hallucinate a successful result if the underlying synthesis job is still pending.

Setup guide

Set up Lovo AI (Genny TTS & Voice Synthesis API) 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": {
        "lovo-ai-genny-tts-voice-synthesis-api-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

agent = Agent(
    "openai:gpt-4o",
    toolsets=[toolset],
    system_prompt="You have access to Lovo AI (Genny TTS & Voice Synthesis API) tools.",
)

result = await agent.run("List recent Lovo AI (Genny TTS & Voice Synthesis API) transactions")
print(result.output)

Common questions about Lovo AI (Genny TTS & Voice Synthesis API) MCP in Pydantic AI

Pydantic AI ensures every piece of data from the synthesis tools is validated. This prevents your agent from acting on corrupt audio URLs or invalid speaker IDs.

Use the `MCPToolset` to import the server. The framework automatically maps the tools and validates their input and output against your defined models.

It does. Because the server follows the protocol, Pydantic AI validates the structure of every tool response, including the status object from `get_tts_job`.

Yes. Pydantic AI is model-agnostic, so you can pair it with any local LLM while keeping the same type-safe interface for your synthesis tools.

The server treats your text as an ephemeral payload. It only touches the content required for the job, and your Pydantic schemas ensure that no unexpected fields are ever processed.
