How to Use the Conflux MCP in VS Code Copilot

Q: How do we configure the Conflux MCP Server for our entire team in VS Code Copilot?

Create a .vscode/mcp.json file in your repository root and commit it to Git. Every team member with the Copilot extension will automatically load the server. This ensures everyone has access to the same blockchain debugging tools.

Q: What is the difference between Core Space and eSpace tools?

Core Space tools use the cfx prefix and support the native Conflux account model. eSpace tools use the eth prefix and offer EVM compatibility. This server supports both spaces, letting you interact with either environment.

Give your VS Code Copilot agent direct access to Conflux Core and eSpace networks.

Share Conflux node status with your team

This tool tracks node status and client versions across your local Conflux network. Your agent calls `cfx_get_status` to pull current epoch heights, network IDs, and node versions into Copilot Chat. You can also check the client version using `cfx_client_version` to ensure everyone is running matching configurations. This eliminates debugging issues caused by mismatched local nodes.

Track transaction receipts inside VS Code Copilot

This tool monitors the execution status of your smart contract deployments in real time. Our MCP tool calls `cfx_get_transaction_receipt` to see if your transaction succeeded or reverted. If you are working on the EVM-compatible eSpace, it uses `eth_get_transaction_receipt` instead. You get clear, readable execution details directly in your chat sidebar.

Query contract logs using this MCP Server

This MCP Server decodes and filters smart contract logs from either network space. The agent executes `cfx_get_logs` or `eth_get_logs` to retrieve historical event data. This allows the model to analyze emitted events and explain state changes. You do not have to copy-paste hex logs into an external decoder anymore.

Setup guide

Set up Conflux MCP in VS Code Copilot

Prerequisites

VS Code 1.99 or later with GitHub Copilot extension
Active Vinkius subscription with a valid endpoint token

1

Open MCP configuration

Open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and run "MCP: Add Server". Select HTTP (Streamable) as the server type. VS Code will create .vscode/mcp.json in your workspace.
2

Add the Conflux MCP

Paste the JSON snippet shown on the right into your .vscode/mcp.json. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Switch to Agent mode

Open Copilot Chat (Cmd+Shift+I / Ctrl+Shift+I) and switch to Agent mode using the dropdown. MCP tools are only available in Agent mode — they do not appear in Edit or Ask modes.
4

Verify the connection

In the Copilot Chat input, type # to list available tools. You should see the Conflux tools listed. Try asking: "List my recent Conflux transactions" and Copilot will invoke them automatically.

.vscode/mcp.json

{
  "mcpServers": {
    "conflux-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
  }

Common questions about Conflux MCP in VS Code Copilot

Create a `.vscode/mcp.json` file in your repository root and commit it to Git. Every team member with the Copilot extension will automatically load the server. This ensures everyone has access to the same blockchain debugging tools.

Yes, the agent can check balances across both spaces. It uses `cfx_get_balance` for Core Space addresses and `eth_get_balance` for eSpace addresses. The results are formatted and displayed directly in your active chat.

The agent queries the next available nonce to prevent transaction collisions. It calls `cfx_get_next_nonce` for Core Space or `eth_get_transaction_count` for eSpace. This helps you write deployment scripts that execute in the correct order.

Core Space tools use the `cfx_` prefix and support the native Conflux account model. eSpace tools use the `eth_` prefix and offer EVM compatibility. This server supports both spaces, letting you interact with either environment.

No, the server only processes public blockchain data, such as contract addresses, block hashes, and transaction receipts. It operates in a secure sandbox and never uploads your local source files or private keys. All queries are executed over encrypted endpoints to maintain total development privacy.
