Assign On-Chain Research Tasks

Give your CrewAI agents specialized roles for blockchain analysis. A 'Watcher' agent can constantly monitor an address for new transactions using `get_tx_list` and `get_tx_list_internal`. When it finds something, it passes the transaction hash to an 'Analyst' agent. The Analyst agent then takes over, using `proxy_eth_get_transaction_by_hash` and `get_tx_receipt_status` to get the full details. This division of labor is what CrewAI is built for, and this MCP server gives them the specific tools they need to do their jobs on the Cronos chain.

Multi-Agent Contract Auditing

Assemble a crew to perform preliminary smart contract analysis. One agent can be tasked with fetching the contract's source with `get_source_code`. A second, more specialized agent can then analyze that code for common patterns or potential issues. A third 'Reporter' agent can summarize the findings. This collaborative process, powered by CrewAI's shared memory and the Cronoscan tools, lets you build a basic, automated audit pipeline that runs without any human input.

Build an Autonomous Cronos Monitor with an MCP Server

Let a crew manage itself. A 'Supply' agent's only job could be to track the total supply of CRO with `get_eth_supply` and an ERC20 token with `get_token_supply`. It reports changes to a 'Price' agent, which checks `get_eth_price`. Based on the data, a 'Decision' agent can then decide if the market movement is significant. This is how you build autonomous systems with CrewAI. Each agent has a narrow focus, using one or two tools from this MCP, and collaborates for a higher-level outcome.

Setup guide

Set up Cronoscan (Cronos Block Explorer) 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 Cronoscan (Cronos Block Explorer) tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

task = Task(
    description="List recent Cronoscan (Cronos Block Explorer) 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="Cronoscan (Cronos Block Explorer) Analyst",
        goal="Access and analyze Cronoscan (Cronos Block Explorer) data via MCP.",
        backstory="Expert analyst with direct Cronoscan (Cronos Block Explorer) access.",
        tools=mcp_tools,
    )

    task = Task(
        description="List recent Cronoscan (Cronos Block Explorer) transactions",
        agent=agent,
        expected_output="A summary of recent activity",
    )

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

Common questions about Cronoscan (Cronos Block Explorer) MCP in CrewAI

It's straightforward. You can pass your Vinkius MCP URL directly into the `mcps` list when defining an Agent. For more control, use the `MCPServerHTTP` class from `crewai.mcp` to filter which specific tools an agent can access.

Yes, that's the recommended approach. You can create a 'Balance Checker' agent that only has access to `get_balance` and a 'Transaction Digger' agent that only uses `get_tx_list`. This role-based specialization makes your crew more efficient and secure.

A great example is a security crew. One agent monitors for large transfers with `get_token_tx`. If it spots one, it alerts a second agent to fetch the contract source code with `get_source_code` for analysis. A final agent can then report the findings.

No. Vinkius handles the authentication. You just need the single MCP Server endpoint URL and token, which you provide to CrewAI. All agents in your crew will use that same authenticated connection.

Data such as wallet addresses and transaction IDs are handled within the Vinkius execution sandbox. While CrewAI agents share memory to collaborate, the actual tool execution happens on our secure, ephemeral infrastructure. All traces of the operation are wiped after the tool call is complete.
