How to Use the Blockscout MCP in CrewAI

Q: Can I monitor live event logs?

Use the getlogs tool to pull event logs matching specific topics. Your agents can parse these logs to track mint events, transfers, or smart contract state changes in real-time.

Deploy autonomous multi-agent teams to monitor blockchains with CrewAI and Blockscout.

Perplexity

Coordinate multi-agent blockchain investigations

The `get_account_transactions` tool retrieves transaction histories for any suspect wallet address. They share memory dynamically, letting them cross-reference internal contract calls retrieved via `get_account_internal_transactions`.

Deploy a CrewAI monitoring team with the Blockscout MCP Server

The `get_total_supply` tool fetches the total circulating supply of native network tokens. By using this MCP Server, your autonomous agents can spot supply anomalies or indexing delays.

Audit smart contracts autonomously

The `get_contract_abi` tool extracts the application binary interface for any smart contract. Solidity files are read directly by the security agent using `get_contract_source_code`.

Setup guide

Set up Blockscout MCP in CrewAI

Prerequisites

Python 3.10+ installed
crewai package (pip install crewai)
Active Vinkius subscription with a valid endpoint token

1

Install CrewAI
Run pip install crewai to install the framework. MCP support is built-in via the mcps parameter.
2

Add the MCP URL to your agent
Pass your Vinkius endpoint directly to the mcps list. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. CrewAI handles tool discovery and caching automatically.
3

Kick off your crew
Create a Crew with your agent and tasks. Call crew.kickoff() — the agent will automatically invoke Blockscout tools as needed.

crew.py

from crewai import Agent, Task, Crew

agent = Agent(
    role="Blockscout Analyst",
    goal="Access and analyze Blockscout data via MCP.",
    backstory="Expert analyst with direct Blockscout access.",
    mcps=[
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ],
)

task = Task(
    description="List recent Blockscout transactions",
    agent=agent,
    expected_output="A summary of recent activity",
)

crew = Crew(agents=[agent], tasks=[task])
result = crew.kickoff()
print(result)

Prerequisites

Python 3.10+ installed
crewai + crewai-tools packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install crewai crewai-tools. The MCPServerAdapter handles lifecycle management and tool conversion.
2

Connect with MCPServerAdapter
Use MCPServerAdapter as a context manager with SseServerParameters pointing to your Vinkius endpoint. The adapter automatically manages connection lifecycle.
3

Assign tools and run
Pass the returned mcp_tools to your agent's tools parameter. The adapter converts MCP tools to native BaseTool objects compatible with all CrewAI agents.

crew.py

from crewai import Agent, Task, Crew
from crewai_tools import MCPServerAdapter
from mcp import SseServerParameters

server_params = SseServerParameters(
    url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)

with MCPServerAdapter(server_params) as mcp_tools:
    agent = Agent(
        role="Blockscout Analyst",
        goal="Access and analyze Blockscout data via MCP.",
        backstory="Expert analyst with direct Blockscout access.",
        tools=mcp_tools,
    )

    task = Task(
        description="List recent Blockscout transactions",
        agent=agent,
        expected_output="A summary of recent activity",
    )

    crew = Crew(agents=[agent], tasks=[task])
    result = crew.kickoff()
    print(result)

Common questions about Blockscout MCP in CrewAI

You simply pass your Vinkius HTTP URL directly into the agent's mcps parameter. The framework automatically discovers all fourteen tools and makes them available to the crew.

Yes, you can use the MCPServerHTTP class from the framework to apply a tool filter. This prevents a research agent from executing raw json_rpc commands while still letting it query balances.

The crew uses a shared memory system to pass outputs from tools like get_transaction between agents. An investigator agent can fetch the tx details, and an analyst agent can immediately read them.

Use the get_logs tool to pull event logs matching specific topics. Your agents can parse these logs to track mint events, transfers, or smart contract state changes in real-time.

Vinkius executes the MCP Server within a zero-trust, ephemeral sandbox. Your Ethereum addresses, transaction hashes, and smart contract ABIs are transmitted securely via encrypted endpoints and never stored.
