How to Use the Moonriver (Moonriver Block Explorer API) MCP in OpenAI Agents SDK

Q: How do I register the Moonriver (Moonriver Block Explorer API) MCP Server with the OpenAI Agents SDK?

Install openai-agents and initialize MCPServerStreamableHttp pointing to your Vinkius endpoint. Pass the server instance inside the mcpservers list when instantiating your Agent.

Q: Can my OpenAI Agents SDK system handle high-volume block queries using this MCP Server?

Yes. You should set cacheToolsList=True in your configuration to avoid fetching the tool schema on every agent turn. The server handles concurrent calls to listblocks and listextrinsics efficiently.

Q: How does the Moonriver (Moonriver Block Explorer API) handle runtime upgrades in OpenAI Agents SDK?

The getmetadata tool pulls the active runtime metadata directly from the network. Your agent reads this data to adapt to upgrades without requiring manual code changes or SDK updates.

Q: How is my blockchain query data secured when using this server?

This server only processes read-only queries like getaccountinfo and transfer lookups, so your private keys are never exposed. Vinkius runs the server in an isolated sandbox, ensuring zero-trust execution for all network requests.

Get live Moonriver blockchain data directly inside your production OpenAI Agents SDK workflows using this MCP Server without writing custom RPC parsers.

Perplexity

Audit network blocks and extrinsics directly

`get_block` fetches raw block details while `list_blocks` pages through recent network activity. Your agent uses these tools to track finality and inspect specific block headers during execution. For granular transaction checks, `get_extrinsic` pulls the exact execution status of any Substrate extrinsic. This lets your agent verify that a transaction actually cleared before moving to the next workflow step.

Track EVM tokens and account transfers in OpenAI Agents SDK

`list_evm_tokens` exposes the active token contracts deployed on the Moonriver network. Your agent pulls this list to identify assets, while `list_transfers` monitors the flow of funds across specific account addresses. The agent combines these tools with `get_account_info` to read the native balance and nonce of any wallet. This MCP integration gives your system real-time visibility into account states without managing external database syncs.

Inspect active runtime metadata

`get_metadata` retrieves the current runtime metadata from the Moonriver network. Your agent parses this schema to understand active pallet configurations and call structures dynamically. Combined with `list_extrinsics`, this tool lets your agent construct or verify transaction payloads based on the exact runtime rules of the active block. It prevents execution failures caused by outdated chain specs.

Setup guide

Set up Moonriver (Moonriver Block Explorer API) MCP in OpenAI Agents SDK

Prerequisites

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

1

Install the SDK

Run pip install openai-agents to install the OpenAI Agents SDK. The MCP integration is built-in — no extra dependencies needed.
2

Connect via SSE transport

Use MCPServerSse with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. The SDK auto-discovers all Moonriver (Moonriver Block Explorer API) tools at runtime.
3

Create your Agent

Pass the MCP to Agent(mcp_servers=[server]). The agent receives Moonriver (Moonriver Block Explorer API) tools as native definitions — JSON schemas resolve automatically.
4

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate Moonriver (Moonriver Block Explorer API) tools and returns structured results. Copy the full example on the right to get started.

agent.py

import asyncio
from agents import Agent, Runner
from agents.mcp import MCPServerSse

async def main():
    async with MCPServerSse(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ) as server:
        agent = Agent(
            name="Moonriver (Moonriver Block Explorer API) Agent",
            instructions="You have access to Moonriver (Moonriver Block Explorer API) tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())

Common questions about Moonriver (Moonriver Block Explorer API) MCP in OpenAI Agents SDK

Install `openai-agents` and initialize `MCPServerStreamableHttp` pointing to your Vinkius endpoint. Pass the server instance inside the `mcp_servers` list when instantiating your Agent.

Yes. You should set `cacheToolsList=True` in your configuration to avoid fetching the tool schema on every agent turn. The server handles concurrent calls to `list_blocks` and `list_extrinsics` efficiently.

The `get_metadata` tool pulls the active runtime metadata directly from the network. Your agent reads this data to adapt to upgrades without requiring manual code changes or SDK updates.

Yes. You can filter the tools exposed by the MCP Server configuration before passing them to the Agent constructor. This limits the agent to reading blocks with `get_block` while blocking account balance checks.

This server only processes read-only queries like `get_account_info` and transfer lookups, so your private keys are never exposed. Vinkius runs the server in an isolated sandbox, ensuring zero-trust execution for all network requests.
