Perplexity

Collaborative blockchain research in CrewAI

Assign research agents to use `get_block` and `get_transaction` for deep dives. The crew shares this memory so the analyst agent has the context it needs. Your agents work in sequence. One finds the raw data, the other writes the summary report.

Autonomous monitoring with CrewAI

Let a monitor agent track address activity using `get_address`. If it sees an anomaly, it passes the data to a moderator agent to take action. You define the rules of engagement. The crew handles the constant checking while you focus on the results.

Escalation workflows in CrewAI

Configure your agents to broadcast transactions via `push_transaction` only after a verification agent approves the payload. It creates a secure pipeline for your operations. No action hits the network without meeting the standards you set for your crew.

Setup guide

Set up Blockchair (Universal Blockchain Search Engine & 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 Blockchair (Universal Blockchain Search Engine & API) tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

task = Task(
    description="List recent Blockchair (Universal Blockchain Search Engine & 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="Blockchair (Universal Blockchain Search Engine & API) Analyst",
        goal="Access and analyze Blockchair (Universal Blockchain Search Engine & API) data via MCP.",
        backstory="Expert analyst with direct Blockchair (Universal Blockchain Search Engine & API) access.",
        tools=mcp_tools,
    )

    task = Task(
        description="List recent Blockchair (Universal Blockchain Search Engine & 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 Blockchair (Universal Blockchain Search Engine & API) MCP in CrewAI

Yes. Add the server to your agent configuration. Each agent in the crew can then use the provided tools independently.

Pass the server URL to your agent's MCP list. Once connected, your agents can call any of the 11 tools during their execution.

It does. Agents can retrieve data with one tool and broadcast a transaction with another to complete an automated task.

You can use a tool filter in your agent setup. This limits the crew to only the specific data tools you authorize.

All interactions are ephemeral. The server processes public address data and network stats without keeping a record of your tasks.
