Type-safe chain metrics via this Pydantic AI MCP Server

The `get_chain_stats` tool fetches aggregate blockchain ecosystem data and validates it against strict runtime schemas. Your Pydantic AI agent ensures that transaction volumes and wallet counts match your expected types before passing them to your application. If the DappRadar API format ever changes, the validation layer catches it instantly. Your system fails loudly with a clear traceback, preventing corrupted data from entering your production databases.

Strict dapp metrics validation

The `get_dapp_metrics` tool retrieves historical activity for specific decentralized applications directly into your typed Python models. Your agent parses user counts and transaction volumes with full IDE autocompletion and static analysis support. You initialize this toolset using the unified MCP toolset class. This connects your agent to the external server over a secure HTTP stream, ensuring type safety without adding overhead.

Validate NFT collections with Pydantic AI

The `get_nft_collection_metrics` tool pulls historical floor prices and trade volumes into your validated agent workflows. Your agent uses these metrics to calculate market trends, confident that every float and string is perfectly typed. Because Pydantic AI is model-agnostic, you can switch between Anthropic and OpenAI models. The validation rules remain exactly the same, protecting your application from model-specific parsing errors.

Setup guide

Set up DappRadar (Web3 Dapp & NFT Analytics) 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": {
        "dappradar-web3-dapp-nft-analytics-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

agent = Agent(
    "openai:gpt-4o",
    toolsets=[toolset],
    system_prompt="You have access to DappRadar (Web3 Dapp & NFT Analytics) tools.",
)

result = await agent.run("List recent DappRadar (Web3 Dapp & NFT Analytics) transactions")
print(result.output)
