Perplexity

Generate code with actual Conflux contract data

This tool fetches real-time contract states to replace static mocks in your development environment. Your Cursor agent calls `cfx_call` or `eth_call` to retrieve real values and injects them directly into your editor. This means your generated scripts use actual on-chain variables. You write cleaner code because the AI references active contract values instead of outdated documentation.

Debug eSpace transactions directly in Cursor

This tool retrieves transaction receipts and execution logs directly inside your editor. When a test transaction fails, this MCP integration uses `eth_get_transaction_receipt` to pull the execution status right into your terminal chat. It can also check the transaction count using `eth_get_transaction_count` to find nonce mismatches. You fix deployment errors faster when the debugging data is right in your editor.

Inspect Core Space account states using this MCP Server

This tool retrieves Core Space account states and sponsorship details for your active workspace. Your agent invokes `cfx_get_account` to retrieve the balance, nonce, and storage root. It also checks sponsorship status with `cfx_get_sponsor_info` to see if your contract's gas is covered. You get all this data without leaving your active code file.

Setup guide

Set up Conflux MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the Conflux MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent Conflux transactions." If the MCP tools are loaded correctly, Cursor will call the Conflux tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

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

Common questions about Conflux MCP in Cursor

Add the server configuration to your `.cursor/mcp.json` file in your project root or global directory. Once added, enable Agent mode in your editor chat. The model will immediately gain access to all twenty-five blockchain tools.

Yes, the agent can broadcast pre-signed transactions to the blockchain. It uses `cfx_send_raw_transaction` or `eth_send_raw_transaction` to send the payload. You handle the signing locally, keeping your keys secure while the editor handles the transmission.

The agent calls the estimation tools to calculate gas limits before you run deployment scripts. It invokes `cfx_estimate_gas_and_collateral` for Core Space and `eth_estimate_gas` for eSpace. This prevents out-of-gas errors during local testing.

You can query any epoch to analyze block distribution. The agent calls `cfx_get_blocks_by_epoch` or `cfx_get_block_by_epoch_number` to gather hashes and block details. This is useful for tracking down transaction latency.

The server never accesses your private keys or local wallet files. It only processes public blockchain queries, transaction hashes, and smart contract addresses that you explicitly request. Your workspace environment remains isolated, ensuring no sensitive credentials leave your machine.
