Connection guides

In claude.ai or the Claude Desktop app, open Customize → Connectors → + → Add custom connector (older versions place Connectors under Settings).

Paste the Brainbox connector URL:

https://brainbox-mcp.thexi.dev/mcp

Sign in with the Brainbox owner account (Google) and approve access when prompted.

Create a Project and paste the memory rules into its instructions (Part 2 below).

Add the server (user scope loads it in every folder):

claude mcp add --transport http --scope user brainbox https://brainbox-mcp.thexi.dev/mcp

Start Claude Code, type /mcp, select brainbox, and choose Authenticate — this is what opens the browser to sign in. The add command alone opens nothing.

Run /mcp again to confirm brainbox shows connected.

Paste the memory rules into CLAUDE.md (project root, or ~/.claude/CLAUDE.md for everywhere).

In ChatGPT (or the Codex app) open Settings → Connectors — enable developer mode first if you don't see it.

Add a custom connector with the Brainbox URL:

https://brainbox-mcp.thexi.dev/mcp

Sign in with the Brainbox owner account (Google) and approve.

Added Brainbox in ChatGPT before? Open the connector's settings and choose Reconnect, then sign in once — no new connector needed.

Paste the memory rules into your custom instructions (or AGENTS.md for Codex projects). ChatGPT may ask permission before individual tool calls depending on your settings — approving is the normal flow.

Add Brainbox to your MCP config:

codex mcp add brainbox --url https://brainbox-mcp.thexi.dev/mcp

Sign in (a separate step — without it Codex reports “MCP startup incomplete (failed: brainbox)”):

codex mcp login brainbox

Headless / CI: skip OAuth entirely and use a machine key via an environment variable:

codex mcp add brainbox --url https://brainbox-mcp.thexi.dev/mcp --bearer-token-env-var BRAINBOX_KEY

Export BRAINBOX_KEY with a key from Part 4, and paste the memory rules into AGENTS.md.

Add Brainbox to your opencode config (~/.config/opencode/opencode.json):

{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "brainbox": {
      "type": "remote",
      "url": "https://brainbox-mcp.thexi.dev/mcp",
      "enabled": true
    }
  }
}

Authenticate once — this opens the browser and stores the tokens:

opencode mcp auth brainbox

Paste the memory rules into AGENTS.md (OpenCode reads it each session).

Run goose configure → Add Extension → Remote Extension (Streamable HTTP), name it brainbox, paste the URL:

https://brainbox-mcp.thexi.dev/mcp

Or edit ~/.config/goose/config.yaml directly:

extensions:
  brainbox:
    name: Brainbox
    type: streamable_http
    uri: https://brainbox-mcp.thexi.dev/mcp
    enabled: true
    timeout: 300

For a one-off session: goose session --with-streamable-http-extension with the same URL. Tip: disable goose's built-in memory extension so the two don't overlap.

Add Brainbox:

amp mcp add brainbox https://brainbox-mcp.thexi.dev/mcp

Start the Amp TUI — for remote OAuth servers Amp opens the browser and stores the tokens automatically.

Paste the memory rules into AGENTS.md.

Reportedly: grok.com/connectors → New Connector → Custom → paste the Brainbox URL → sign in:

https://brainbox-mcp.thexi.dev/mcp

If the connectors panel is absent or behind a paid tier in your account, that is the current limit — nothing here is confirmed by Grok's documentation.

Where supported, paste the memory rules into a Project's or your custom instructions.

There are two apps — the Antigravity agent manager and the Antigravity IDE; set up whichever you use (the panel exists in both).

Agent Manager → ••• → Customizations → Add MCP → command npx with these args:

-y mcp-remote@latest https://brainbox-mcp.thexi.dev/mcp

Sign in with the Brainbox owner account when the browser opens.

Customizations → Rules → + Global, and paste the memory rules.

There is no verified Gemini app setup in this guide yet.

For a connection you can use now, choose one of the verified guides above. The Antigravity guide is also available, marked as a legacy recipe.

Add the server with a machine key from Part 4:

openclaw mcp add brainbox --url https://brainbox-mcp.thexi.dev/mcp --transport streamable-http --header "Authorization=Bearer <bbk_key>"

Verify the connection — it should list the registered Brainbox tools:

openclaw mcp probe brainbox

Paste the memory rules into ~/.openclaw/workspace/AGENTS.md and keep that config private — it holds your key.

Add to ~/.hermes/config.yaml — the ${…} substitution keeps your key out of the file:

mcp_servers:
  brainbox:
    url: "https://brainbox-mcp.thexi.dev/mcp"
    headers:
      Authorization: "Bearer ${BRAINBOX_KEY}"

Export BRAINBOX_KEY with a machine key from Part 4, then test — it should list the registered Brainbox tools:

hermes mcp test brainbox

Paste the memory rules into your Hermes profile / system prompt.
