Connect your agent

Let your AI coding agent draft a build receipt for your project. You review and approve it before anything is published. We never receive your code or prompts.

1. Create a token

Go to Settings → Agent tokens, create a token and copy it. Keep it private: anyone with it can publish receipts as you. You can revoke it at any time.

2. Add cobuilt to your agent

Server URL: https://cobuilt.dev/mcp. Replace YOUR_TOKEN with your token, or keep it in the environment variable shown.

Claude Code

Terminal

claude mcp add --transport http --scope user cobuilt https://cobuilt.dev/mcp \
  --header "Authorization: Bearer YOUR_TOKEN"

Cursor

Set COBUILT_TOKEN in your environment, then restart Cursor.

~/.cursor/mcp.json

{
  "mcpServers": {
    "cobuilt": {
      "url": "https://cobuilt.dev/mcp",
      "headers": {
        "Authorization": "Bearer ${env:COBUILT_TOKEN}"
      }
    }
  }
}

VS Code (GitHub Copilot)

VS Code asks for the token when the server starts and stores it securely.

.vscode/mcp.json

{
  "inputs": [
    {
      "type": "promptString",
      "id": "cobuilt-token",
      "description": "cobuilt token",
      "password": true
    }
  ],
  "servers": {
    "cobuilt": {
      "type": "http",
      "url": "https://cobuilt.dev/mcp",
      "headers": {
        "Authorization": "Bearer ${input:cobuilt-token}"
      }
    }
  }
}

OpenAI Codex

Set COBUILT_TOKEN in your environment.

~/.codex/config.toml

[mcp_servers.cobuilt]
url = "https://cobuilt.dev/mcp"
bearer_token_env_var = "COBUILT_TOKEN"

Another MCP client? Any client that supports remote (Streamable HTTP) MCP servers with a bearer token header should work. If yours doesn't, tell us.

3. Ask your agent

When a project (or a milestone) is done, say:

Prompt

Publish this project to cobuilt.

The agent checks your existing projects, drafts what it did, what you did and what went wrong, proposes an AI level for you to confirm, and shows you the full draft. It only submits after you approve. New projects are reviewed within 24 hours.

How receipts work : evidence levels and exactly what is sent.
