Strictly typed Coinbase data in Pydantic AI

Every response from `get_buy_price` or `get_sell_price` gets validated against your Pydantic models. If the exchange returns a malformed price, your agent catches it instantly. This stops bad data from propagating through your system. You define the schema, and the agent enforces it, ensuring your logic only operates on verified, clean numbers.

Pydantic AI agents querying asset info

Fetch currency metadata using `get_currencies` and validate the result against your strict type definitions. Your agent knows exactly what to expect for precision and sort order. Use `get_exchange_rates` to get conversion factors for your calculations. Because you use Pydantic AI, any type mismatch triggers an immediate error, preventing silent failures in your financial logic.

Reliable Coinbase interaction in Pydantic AI

Sync your agent operations using `get_time`. It provides the reliable timestamp you need for your validation logic to work correctly. Compare multiple assets across your portfolio using `get_public_prices`. The server returns the data, and your agent validates the entire set before making a single decision.

Setup guide

Set up Coinbase 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": {
        "coinbase-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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

Common questions about Coinbase MCP in Pydantic AI

The framework automatically maps server responses to your defined Pydantic models. If the API output doesn't match your fields, the agent raises a validation error.

Yes, use the `MCPToolset` class. It supports both Streamable HTTP and SSE transports for your agent connection.

By using strict Pydantic models, you force the agent to reject any data that doesn't fit your schema. It keeps the agent grounded in the actual API response.

You can configure your agent to call the server multiple times, passing different parameters to check limits and status across various payment methods.

The server runs in a Vinkius-managed sandbox. Your Pydantic models validate the structure of the currency data, and the data itself is never stored persistently within the agent's memory.
