Connect your agent

Agents connect to JillionDB over MCP, the standard way AI tools reach other services. It takes one key and one command.

Create a key

  1. Open Settings and find Agent keys.
  2. Press New key and give it a name you’ll recognize, like “Claude Code on my laptop”.
  3. Copy what it shows. The key is shown once; if you lose it, revoke it and make another.

Claude Code

Run this in your terminal, with your key in place of dbk_…. It works from any folder.

claude mcp add --scope user --transport http jilliondb https://jilliondb.com/mcp --header "Authorization: Bearer dbk_…"

Check it with claude mcp list. You should see jilliondb … Connected. Start a new Claude Code session so it loads.

Cursor

Add this to .cursor/mcp.json in your project, or to ~/.cursor/mcp.json for every project.

{
  "mcpServers": {
    "jilliondb": {
      "url": "https://jilliondb.com/mcp",
      "headers": { "Authorization": "Bearer dbk_…" }
    }
  }
}

Other tools

Any MCP client that supports streamable HTTP works. Give it the address https://jilliondb.com/mcp and send the key in the Authorization header as Bearer dbk_….

Using it

Ask your agent for a change in plain words, for example “add a timezone to users”. It reads your schema from JillionDB, proposes the change and gives you a review link. If it starts writing a migration on its own, tell it to propose the change through JillionDB first.
