How to Use the Kynver MCP Server in Cursor and Claude

If you build AI agents in Cursor, Claude Desktop, or VS Code, you can manage your entire Kynver presence without ever leaving your coding environment — registering agents, checking verification status, starting KYC, even getting ready-to-use tracking setup code.

What Is the Kynver MCP Server?

MCP stands for Model Context Protocol — a standard that lets AI coding tools connect to external services as tools the AI can call on your behalf.

The Kynver MCP server gives your AI assistant a set of Kynver-specific tools: - Register an agent on Kynver without filling out a form - Look up any agent — profile, trust score, verification status - Advance your verification — start KYC, pass the ownership challenge, submit the questionnaire - Get execution tracking setup code pre-filled with your agent's DID

In plain terms: your AI assistant becomes a hands-free way to manage your Kynver account while you are building.

What You Need Before Starting

  • Node.js 18 or later on your computer. Not sure if you have it? Open a terminal and type node --version. If you see something like v20.x.x, you are set. If not, download it from nodejs.org and restart your IDE after installing.
  • Cursor, Claude Desktop, or VS Code with GitHub Copilot.
  • A Kynver account.
  • A Kynver API key if you want write tools (register, verify, etc.). Read-only tools work without one.
To get an API key: Dashboard → your agent → Settings → API Keys → Create key. See Kynver API Keys api keys for the full guide.

Setting Up in Cursor

Option A — using the settings UI: - Open Cursor → Settings → MCP → Add new MCP server - Name: kynver, Command: npx, Arguments: -y @kynver-app/mcp-server - Add an env var: KYNVER_API_KEY = your key - Save. Cursor downloads and starts the server automatically.

Option B — using a config file. Create .cursor/mcp.json in your project root:

{
  "mcpServers": {
    "kynver": {
      "command": "npx",
      "args": ["-y", "@kynver-app/mcp-server"],
      "env": {
        "KYNVER_API_KEY": "<your-api-key>"
      }
    }
  }
}

Leave out the KYNVER_API_KEY line entirely if you do not have one yet — read-only tools still work.

Setting Up in Claude Desktop

Step 1 —
Open Claude Desktop → Settings → Developer → Edit Config. This opens a JSON config file.
Step 2 —
Add the Kynver section inside "mcpServers":
{
  "mcpServers": {
    "kynver": {
      "command": "npx",
      "args": ["-y", "@kynver-app/mcp-server"],
      "env": {
        "KYNVER_API_KEY": "<your-api-key>"
      }
    }
  }
}
Step 3 —
Save and fully restart Claude Desktop (quit and reopen — it must restart completely to pick up the new server).

Config file location: - macOS: ~/Library/Application Support/Claude/claude_desktop_config.json - Windows: %APPDATA%\Claude\claude_desktop_config.json

Setting Up in VS Code

Create .vscode/mcp.json in your project root:

{
  "servers": {
    "kynver": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@kynver-app/mcp-server"],
      "env": {
        "KYNVER_API_KEY": "<your-api-key>"
      }
    }
  }
}

Save the file. VS Code detects the server and connects automatically.

What You Can Ask It to Do

Once connected, just ask your AI assistant naturally. Examples: - "Register my agent on Kynver — it's called [name], a [description] at [URL]." - "What's the verification status of the agent with slug my-agent?" - "Start the KYC process for my agent." - "Show me the execution tracking setup code for my LangChain agent." - "List verified agents in the productivity category."

The AI calls Kynver on your behalf and summarizes the result in the chat.

What npx Does

npx is a tool that comes with Node.js. When your IDE runs npx -y @kynver-app/mcp-server, it automatically downloads the latest version of the Kynver MCP server from the npm registry and runs it. You do not need to install anything separately. The -y flag means "yes, proceed" so it does not pause to ask.

Troubleshooting

"command not found: npx" Node.js is not installed or not in your PATH. Download it from nodejs.org and restart your IDE after installing.

Tools do not appear in Cursor Go to Settings → MCP and check that the server shows a green dot. If it is red or missing, click the refresh icon to restart the server.

Claude Desktop does not show Kynver tools Make sure you fully quit and reopened Claude Desktop after editing the config. Also check the JSON carefully for missing commas or brackets — a single syntax error prevents the file from loading.

API key errors Check that the key is copied correctly (no extra spaces) and belongs to the agent you are working with. Write tools require KYNVER_API_KEY; read-only tools do not.
