How to Use the Bobascan (Boba L2 Network Block Explorer API) MCP in Pydantic AI

Q: How do I initialize the Bobascan (Boba L2 Network Block Explorer API) toolset in Pydantic AI?

Use the unified MCPToolset class pointing to your Vinkius HTTP endpoint. This registers the MCP Server tools directly into your Agent's toolsets list to make all 25 blockchain explorer tools available to your model.

Perplexity

Type-Safe Contract Auditing and ABI Parsing

`get_abi` and `get_source_code` stop malformed contract data from breaking your agentic loops. Pydantic AI validates every byte of the contract ABI and the source code against strict Python types. If the Bobascan API returns an unexpected schema, the framework raises a validation error immediately. This prevents your agent from hallucinating contract structures or trying to execute invalid methods.

Validate Multi-Wallet Balances at Runtime

`get_ether_balance_multi` and `get_token_balance` ensure your wallet queries are accurate before taking action. Your agent gets wallet balances, and Pydantic AI ensures the returned values are valid integers and strings. This strict validation is crucial for financial agents. By wrapping the MCP Server tools in type-safe schemas, you prevent silent data corruption when checking balances across dozens of Boba L2 addresses.

Strict Transaction Monitoring with Pydantic AI

`get_token_nft_tx` and `get_token_tx` monitor ERC721 and ERC20 transfers without worrying about broken data fields. Your agent can read transfer events, with every event field validated against your Pydantic models. This ensures that block numbers, transaction hashes, and gas costs fetched via `proxy_get_transaction_receipt` are formatted correctly. Your agent can confidently parse transaction histories without risking runtime crashes.

Setup guide

Set up Bobascan (Boba L2 Network Block Explorer 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": {
        "bobascan-boba-l2-network-block-explorer-api-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

agent = Agent(
    "openai:gpt-4o",
    toolsets=[toolset],
    system_prompt="You have access to Bobascan (Boba L2 Network Block Explorer API) tools.",
)

result = await agent.run("List recent Bobascan (Boba L2 Network Block Explorer API) transactions")
print(result.output)

Common questions about Bobascan (Boba L2 Network Block Explorer API) MCP in Pydantic AI

Pydantic AI enforces type safety at the application boundary. When your agent calls `get_tx_list`, the framework validates the transaction list structure, ensuring your agent never processes corrupt block explorer data.

Use the unified `MCPToolset` class pointing to your Vinkius HTTP endpoint. This registers the MCP Server tools directly into your Agent's toolsets list to make all 25 blockchain explorer tools available to your model.

The framework raises a validation error immediately. This stops the agent from making decisions based on incomplete or wrongly parsed data, which is vital when handling raw transaction receipts.

Yes, Pydantic AI is model-agnostic. You can pair this server with local models or commercial APIs to query Boba block data, verify smart contracts, and check transaction statuses.

The MCP Server only queries public ledger data like contract ABIs and transaction histories. No private keys or seed phrases are ever processed or transmitted, keeping your wallet credentials completely secure.
