How to Use the Gong MCP in Pydantic AI

Q: How does Pydantic AI handle validation errors from the Gong MCP Server?

If a tool like getcallstats returns data that violates your Python model, the framework throws a validation error immediately. This prevents your agent from making decisions based on malformed or incomplete sales data.

Q: Can I use the deprecated HTTP client with this Gong integration in Pydantic AI?

No, you should use the unified MCPToolset class pointing to your Vinkius HTTP URL. This is the recommended approach for modern setups and ensures compatibility with all 14 sales tools.

Q: How do I initialize the Gong MCP server toolset within a Pydantic AI agent?

Instantiate MCPToolset with your server's endpoint and pass it to the Agent constructor via the toolsets argument. The agent will validate all incoming payloads from tools like listusers at runtime.

Validate Gong sales transcripts and deal metrics at runtime using Pydantic AI agents that fail loudly instead of passing bad data.

Type-Safe Gong Data Validation with Pydantic AI

Stop worrying about your agent hallucinating mock fields from your sales pipeline. When your Pydantic AI agent queries `list_deals`, every single returned field is validated against strict Python type schemas at runtime. If the Gong API returns an unexpected payload structure, the framework raises a validation error immediately. This prevents corrupted data from polluting your downstream databases or breaking your production agent pipelines.

Audit Sales Coaching with Strict Schemas

Ensure your automated feedback loops are built on clean data. Your Pydantic AI agent can retrieve structured scores using `list_call_scores` and verify that every scorecard matches your exact internal metrics. By parsing the output of `list_scorecards` through a validated schema, you guarantee that coaching recommendations are based on actual performance metrics. The agent will refuse to process incomplete or malformed scorecards.

Track Call Performance Without Silent Failures

Build monitoring systems that fail loudly when things go wrong. When querying call statistics using `get_call_stats` or listing user directories with `list_users`, this MCP Server ensures your agent receives strongly typed responses. If a network glitch or API change alters the structure of `get_call`, your system catches the discrepancy instantly. You get a clean stack trace instead of an agent silently guessing what the missing data meant.

Setup guide

Set up Gong 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": {
        "gong-alternative-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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