Autonomous blockchain research with CrewAI

Assign a research agent to query chain state using `get_block_by_height` or `get_blockchain`. The crew gathers the info, while your analyst agent interprets the findings. This division of labor means your agents can monitor market trends or network health 24/7. They work together to turn raw chain data into actionable intelligence.

Collaborative transaction monitoring

Set up a monitor agent to watch addresses with `get_address` and report back to the lead agent. Your crew can detect suspicious behavior or balance changes in real-time. Shared memory allows the crew to remember previous transactions while investigating new ones. It builds a persistent record of activity without human intervention.

Automated testnet funding

Give your test agents access to `fund_beth_test_address` or `fund_bcy_test_address` to keep your dev environment running. Your agents will top off their own wallets as needed. This allows your crew to run thousands of test transactions without you ever needing to manually top up a testnet balance. It keeps the development cycle moving fast.

Setup guide

Set up BlockCypher (Multi-chain Blockchain Developer API) 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 BlockCypher (Multi-chain Blockchain Developer API) tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

task = Task(
    description="List recent BlockCypher (Multi-chain Blockchain Developer API) 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="BlockCypher (Multi-chain Blockchain Developer API) Analyst",
        goal="Access and analyze BlockCypher (Multi-chain Blockchain Developer API) data via MCP.",
        backstory="Expert analyst with direct BlockCypher (Multi-chain Blockchain Developer API) access.",
        tools=mcp_tools,
    )

    task = Task(
        description="List recent BlockCypher (Multi-chain Blockchain Developer API) transactions",
        agent=agent,
        expected_output="A summary of recent activity",
    )

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

Common questions about BlockCypher (Multi-chain Blockchain Developer API) MCP in CrewAI

Pass the server URL into the agent's MCP configuration list. The agents will then gain access to the full suite of blockchain tools for their tasks.

Yes, CrewAI uses shared memory to store outputs. One agent can query the chain, and the others can access that data in their own prompts.

Absolutely, your manager agent can delegate specific chain tasks to specialized workers. This hierarchical structure keeps your agent tasks organized and efficient.

Use the tool_filter option in your agent setup to specify exactly which tools each agent can use. This prevents agents from performing actions they don't need.

Your private keys and address information are encrypted at rest and never shared between agents. The sandbox keeps your credentials isolated from the agent memory logs.
