Wire it into the AI you already use.

ChatGPT Plus · Pro · Business · Enterprise

Set up on chatgpt.com on a computer — once added there, it’s available in the ChatGPT phone app too (confirmed on-device).

1. On chatgpt.com: Settings → find and turn on Developer mode. OpenAI moves this switch around — it’s currently under Security and login; on some accounts it’s under Apps → Advanced settings.
2. Settings → Apps (some accounts say Plugins) → the + / Create button → name it exascale, paste your personal link as the MCP server URL, Authentication: None → Create. ChatGPT lists our tools — that means you’re connected.
3. In a new chat: click the + next to the message box → enable exascale. (Developer-mode connectors are chosen per chat — if ChatGPT isn’t using the tools, this step is the one that was missed.)

Steps checked against OpenAI’s docs 10 Jul 2026; phone availability confirmed on-device 13 Jul 2026.

Claude Every plan — including Free

Add it once on claude.ai — it then shows up in the Claude apps on your phone automatically (confirmed on-device).

1. Open claude.ai/settings/connectors → Add custom connector.
2. Paste your personal link → Add. Authentication: None — nothing else to fill in.
3. In any chat, the tools are under the + menu → Connectors. On your phone: log out and back in if it doesn’t appear right away.

Grok Custom connectors — paid tier reported

Setup at grok.com/connectors; connectors work on Grok web, iOS, and Android. xAI’s docs don’t state the plan requirement — third-party reporting says paid SuperGrok.

1. Go to grok.com/connectors → New Connector → Custom.
2. Paste your personal link as the MCP server URL — Authentication: None.

Steps checked against xAI’s docs 10 Jul 2026; plan gate unverified.

Perplexity Pro · Max · Enterprise

Custom connectors need a paid Perplexity plan.

1. Account Settings → Connectors → + Custom connector → Remote.
2. Name it exascale, paste your personal link, Authentication: None → Add.

Gemini Honest answer: limited

The regular Gemini app cannot add custom connectors — that’s gated to the Google AI Ultra tier via Spark. Your options:

1. Google AI Ultra: gemini.google.com → Settings & help → Connected Apps → Custom apps for Spark → Add a custom app → paste your personal link. Once added on web, it works in the Gemini phone app too.
2. Gemini CLI (terminal): see the Terminal agents card.
3. No Ultra? See the data in the live demo, or connect a different AI above.

Terminal agents One line each

Terminal agents take your key as a header. Swap exa_your-code for the key in your welcome email:

# Claude Code
claude mcp add --transport http exascale https://api.exascale.build/mcp \
  --header "Authorization: Bearer exa_your-code"

# Codex CLI
codex mcp add exascale --url https://api.exascale.build/mcp \
  --header "Authorization: Bearer exa_your-code"

# Gemini CLI — add to ~/.gemini/settings.json under mcpServers:
#   "exascale": { "httpUrl": "https://api.exascale.build/mcp",
#                 "headers": { "Authorization": "Bearer exa_your-code" } }

Or just paste your personal link (key in the URL) if the agent prefers a bare URL. Commands checked 10 Jul 2026.
