How to Use the BlockCypher (Multi-chain Blockchain Developer API) MCP in AutoGen

Q: How do I register the BlockCypher (Multi-chain Blockchain Developer API) tools in AutoGen?

Install autogen-extmcp. Use the mcpservertools adapter with your Vinkius HTTP URL, and pass the resulting tool list directly into your AssistantAgent constructor.

Q: Do I need a token for every tool in this server?

No. Public read tools like getblockbyhash and getaddressbalance do not require a token, but write operations like createwebhook and sendtransaction do.

Let multiple AutoGen agents debate, verify, and execute multi-chain transactions through a secure consensus workflow.

Multi-Agent Transaction Consensus via AutoGen

This BlockCypher MCP Server allows your AutoGen agents to coordinate complex blockchain operations. One agent uses `get_address_balance` to verify funds, while a compliance agent reviews the transaction details before letting a third agent execute `new_transaction`. This multi-agent debate ensures no single agent can unilaterally broadcast a transaction. They must agree on the gas fees and destination address before passing the raw hex to `send_transaction`.

Automated Testnet Faucet Management

The `fund_bcy_test_address` and `fund_beth_test_address` tools allow your automated QA agents to provision their own test environments. An agent detects a low balance, triggers the faucet, and verifies the credit using `get_address`. This makes integration testing completely autonomous. Your agents don't stop working when they run out of test tokens; they simply request more and resume their verification steps.

Smart Contract Auditing and Deployment

The `create_eth_contract` tool is managed by a deployment agent, but only after a critic agent reviews the contract bytecode. Once consensus is reached, the deployment agent executes the tool and monitors the block height via `get_block_by_height`. After deployment, a verification agent calls `call_eth_contract_method` to run live sanity checks. If any test fails, the agents log the error and halt the pipeline.

Setup guide

Set up BlockCypher (Multi-chain Blockchain Developer API) MCP in AutoGen

Prerequisites

Python 3.10+ installed
autogen-ext[mcp] package
Active Vinkius subscription with a valid endpoint token

1

Install AutoGen with MCP
Run pip install "autogen-ext[mcp]" autogen-agentchat. The MCP extension includes mcp_server_tools for stateless tool access.
2

Fetch tools from the MCP
Call mcp_server_tools(SseServerParams(url=...)) with your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Run your agent
Pass the tools to AssistantAgent and call agent.run(). The agent invokes BlockCypher (Multi-chain Blockchain Developer API) tools and returns structured results.

agent.py

from autogen_ext.tools.mcp import SseServerParams, mcp_server_tools
from autogen_agentchat.agents import AssistantAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient

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

tools = await mcp_server_tools(server_params)

agent = AssistantAgent(
    name="BlockCypher (Multi-chain Blockchain Developer API)_assistant",
    model_client=OpenAIChatCompletionClient(model="gpt-4o"),
    tools=tools,
)

result = await agent.run("List recent BlockCypher (Multi-chain Blockchain Developer API) data")
print(result.messages[-1].content)

Prerequisites

Python 3.10+ installed
autogen-ext[mcp] + autogen-agentchat
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Same packages as above. McpWorkbench is ideal when your agent needs stateful sessions across multiple tool calls.
2

Use McpWorkbench as context manager
Wrap your agent in async with McpWorkbench(...) to maintain shared state and resources. The workbench manages the full MCP session lifecycle.
3

Run with workbench
Pass workbench=workbench to your agent. State is preserved across multiple tool calls within the same session.

agent.py

from autogen_ext.tools.mcp import McpWorkbench, SseServerParams
from autogen_agentchat.agents import AssistantAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient

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

async with McpWorkbench(server_params) as workbench:
    agent = AssistantAgent(
        name="BlockCypher (Multi-chain Blockchain Developer API)_assistant",
        model_client=OpenAIChatCompletionClient(model="gpt-4o"),
        workbench=workbench,
    )

    result = await agent.run("List recent BlockCypher (Multi-chain Blockchain Developer API) data")
    print(result.messages[-1].content)

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

Install autogen-ext[mcp]. Use the mcp_server_tools adapter with your Vinkius HTTP URL, and pass the resulting tool list directly into your AssistantAgent constructor.

No. The MCP Server generates the unsigned transaction skeleton via `new_transaction`. Your local application must sign the transaction before an agent can broadcast it using `send_transaction`.

They share the tools list generated by the MCP adapter. Each agent can call tools like `get_blockchain` or `get_transaction` independently based on their assigned roles.

No. Public read tools like `get_block_by_hash` and `get_address_balance` do not require a token, but write operations like `create_webhook` and `send_transaction` do.

The token is kept inside the Vinkius MCP sandbox. It is never exposed in the chat history or agent prompts, preventing agents from leaking your secrets during their debates.
