Connect Claude or ChatGPT to Arbitron

What you get

Arbitron can be added to an AI assistant as a connector (the technical name is an MCP server). After that you ask Claude, ChatGPT or another assistant a question in your own words, and it takes the answer from Arbitron instead of guessing.

Market data

Funding rates on every venue, one coin's funding across exchanges, funding history, live spreads, spread backtests, the listings calendar and your API usage.

Your account

Your trading cards, trades and PnL by day or month, balances and positions, balance history, connected exchange accounts, your place on the leaderboard, and your plan and payments.

Knowledge base

It searches this knowledge base and reads any article in English, Russian, Ukrainian or French, so it can explain how a setting works.

Read-only

Every Arbitron tool only reads. The assistant can't place orders, start or stop a card, or change a setting, and it never sees your exchange API keys.

Connecting takes about a minute. You paste one address into the assistant, sign in to Arbitron and click "Allow" on the approval page. You don't copy any password or key.

How the connection works

You ask in plain words. The assistant asks Arbitron and shows you the answer.

The address to paste

Every assistant in this guide uses the same one.

Before you start

You need two things: an Arbitron account and an assistant that can add a custom connector. Every Arbitron plan works, including an account with no plan at all.

Every lookup uses your API quota

Each time the assistant asks Arbitron for something, that is one API request on your plan, and one answer can take several. Without a plan you get 3,000 requests a month and 20 a minute, market data is 15 minutes delayed, funding history goes back 7 days and the spread backtest hides its top rows. Scanner gives 30,000 a month (60 a minute), Trader 100,000 (120) and Prime 500,000 (300). Details on Pricing.

Not every assistant can add a connector, and some need a paid plan. The table shows where each one stands.

Which assistants work

Checked in September 2026. After you sign in, each of them can also read your own account, as long as the approval page lists it. Plans and menus change, so check your assistant if something looks different.

Not supported yet

Gemini Microsoft Copilot DeepSeek

These apps can't add a custom connector on a personal account yet. Their business versions are set up by a company admin and aren't covered here.

Claude: web, desktop app and phone

These steps are for Claude Free, Pro and Max. A Free account can have one custom connector.

1
Open Connectors
In Claude on the web or in the desktop app, go to "Customize", then "Connectors". Direct link: claude.ai/customize/connectors.
2
Add a custom connector
Click "+", then "Add custom connector".
3
Enter the name and address
Name: Arbitron. URL: https://arbitron.app/mcp. Leave "Advanced settings" empty and click "Add".
4
Connect and sign in
Click "Connect". Claude opens Arbitron in a new window: sign in and click "Allow".
5
Switch it on in a chat
In a chat, click "+" at the bottom left (or type "/"), open "Connectors" and turn Arbitron on. If Arbitron isn't used in a new chat, check this toggle there.

The fields say "Detected"?

Claude is rolling out a new version of this dialog. If you see it, keep the defaults: "Sign in now" and "Use Claude's published identity (recommended)".

Tool approvals

Claude asks before it uses a tool. Every Arbitron tool only reads, so "Always allow" is safe. To set it once for all chats, open "Customize" → "Connectors" → Arbitron and pick "Always allow", "Needs approval" or "Blocked" for each tool.

Claude Team and Enterprise

Only an Owner or Primary Owner can add the connector. They open "Organization settings" → "Connectors" → "Add" → "Custom" → "Web", paste the address and click "Add". Then each member opens "Customize" → "Connectors", finds the entry labeled "Custom" and clicks "Connect".

On your phone

Add Arbitron on the web or in the desktop app first. The desktop app shares the same connectors, and they show up in the phone app after you sign out and back in. Adding a connector on the phone itself is still in beta.

ChatGPT

Custom connectors need ChatGPT Plus, Pro, Business, Enterprise or Edu. The Free plan can't add them. Set it up on chatgpt.com in a browser; after that it should also appear in the ChatGPT apps. These steps are for Plus and Pro.

1
Turn on Developer mode
Open "Settings" → "Security and login" → "Developer mode". If you don't see it there, look in "Settings" → "Apps" (or "Apps & Connectors") → "Advanced settings". OpenAI moved it in mid-2026.
2
Create a new app
Open "Plugins" at chatgpt.com/plugins and click "+". In older versions it is "Settings" → "Apps" → "Create".
3
Enter the name and address
Name: Arbitron. URL: https://arbitron.app/mcp.
4
Choose OAuth
Set "Authentication" to OAuth. Leave the client ID and client secret empty. If ChatGPT asks how to register the client, keep the automatic option.
5
Create and sign in
Click "Create", sign in to Arbitron and click "Allow". The list of Arbitron tools appears.
6
Use it in a chat
In the message box, click "+" → "Developer mode" and select Arbitron. In older versions: "+" → "More" → Arbitron. Starting your message with "Using Arbitron, …" helps ChatGPT pick the right tool.

The "elevated risk" warning is expected

OpenAI shows this warning for Developer mode and for every custom app, whoever made it. It doesn't point to a problem with Arbitron. Arbitron's tools only read data.

ChatGPT Business, Enterprise and Edu

On Business, only admins and owners can use Developer mode. An admin creates the app, then publishes it for the workspace in "Workspace settings" → "Apps" → "Drafts" → "Publish". On Enterprise and Edu, an admin first turns on Developer mode in "Workspace Settings" → "Permissions & Roles" → "Connected Data" and can give it to members.

Perplexity, Mistral Le Chat and Grok

Perplexity works on paid plans. On Enterprise, an admin has to allow custom connectors first.

1
Open "Account settings" → "Connectors", click "+ Custom connector" and choose "Remote".
2
Enter the name Arbitron and the URL https://arbitron.app/mcp. Set "Authentication" to OAuth and the transport to Streamable HTTP.
3
Tick the acknowledgement box and click "Add".
4
Click Arbitron in the connector list, sign in to Arbitron and click "Allow".
5
In a chat, turn Arbitron on under "Sources".

Mistral Le Chat works on every plan, including Free. The feature is in beta, and Mistral renames parts of the app from time to time: if a menu looks different, look for the "Connectors" section. On Team and Enterprise, a workspace admin adds it.

1
On chat.mistral.ai, open "Connectors" and click "+ Add Connector".
2
Open the "Custom MCP Connector" tab. Enter a name without spaces, such as Arbitron, and the Server URL https://arbitron.app/mcp.
3
Click "Connect", sign in to Arbitron and click "Allow".

Grok is set up on grok.com. It may need a paid plan. On Grok Business and Enterprise, an admin adds the connector first.

1
Open grok.com/connectors and click "New Connector".
2
Choose "Custom" and paste https://arbitron.app/mcp.
3
Sign in to Arbitron and click "Allow".

Grok asks for a Client ID?

Then Grok can't connect to Arbitron yet. Use Claude or ChatGPT for now.

For developers: Claude Code, Codex, Cursor and more

Coding tools use the same address. The first time, each one opens your browser so you can sign in to Arbitron and click "Allow". Copy the snippet for your tool below.

Gemini CLI

Gemini CLI works only for Gemini Code Assist and paid Gemini API users. Since June 18, 2026 it no longer serves free accounts or individual Google AI Pro and Ultra plans.

API key instead of sign-in

A tool that can't sign in with OAuth can use an API key from AI assistants & API, sent as the header Authorization: Bearer arb_live_…. When you create the key, keep "MCP server (assistants using this key)" ticked. Through MCP, a key gives market data and the knowledge base only; reading your account there needs the sign-in. Never paste a key into a shared config file, a repository or an install link.

Setup snippets

Copy, paste, then sign in to Arbitron when the browser opens.

Claude Code

Run it in the terminal. Then type /mcp in a Claude Code session, pick arbitron and sign in. "claude mcp list" should show "✔ Connected". If Claude Code uses your claude.ai login, connectors you added on claude.ai appear here too.

Terminal

claude mcp add --transport http --scope user arbitron https://arbitron.app/mcp

Codex

Then run "codex mcp login arbitron" to sign in in your browser. The Codex CLI and the IDE extension share this setting. Check it with "codex mcp list".

Terminal

codex mcp add arbitron --url https://arbitron.app/mcp

Cursor

Add to Cursor

Use the button, or add this to ~/.cursor/mcp.json. Then open "Settings" → "Tools & MCP" and click the server to sign in.

~/.cursor/mcp.json

{
  "mcpServers": {
    "arbitron": { "url": "https://arbitron.app/mcp" }
  }
}

VS Code

Add to VS Code

For GitHub Copilot agent mode. Use the button, add this to .vscode/mcp.json, or run "MCP: Add Server" from the Command Palette, choose HTTP, paste the address and pick Global. If sign-in gets stuck, run "Authentication: Remove Dynamic Authentication Providers".

.vscode/mcp.json

{
  "servers": {
    "arbitron": { "type": "http", "url": "https://arbitron.app/mcp" }
  }
}

Windsurf

Add this to ~/.codeium/windsurf/mcp_config.json, then click "Authenticate" in the MCPs panel.

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "arbitron": { "serverUrl": "https://arbitron.app/mcp" }
  }
}

Zed

Add this to your settings, or go to "Settings" → "AI" → "MCP Servers" → "Add Remote Server".

~/.config/zed/settings.json

{
  "context_servers": {
    "arbitron": { "url": "https://arbitron.app/mcp" }
  }
}

Gemini CLI

Only for Code Assist and paid Gemini API users. Run the first line, then the second inside Gemini CLI.

Terminal

gemini mcp add --transport http arbitron https://arbitron.app/mcp

Gemini CLI

/mcp auth arbitron

Any other app

For apps that can only run a local server, such as JetBrains AI Assistant, use this bridge as the command. It opens your browser to sign in. To reset the sign-in, delete the ~/.mcp-auth folder.

Terminal

npx -y mcp-remote@latest https://arbitron.app/mcp

What to ask

Ask the way you would ask a colleague. The assistant picks the Arbitron tools itself and often combines several in one answer. Each answer carries the time the data was taken and a link to the matching Arbitron page, and most assistants show them.

Getting better answers

If the assistant answers from memory, start with "Using Arbitron, …". Trade history comes in pieces of up to 31 days and balance history up to 180 days, so ask for one month of trades at a time.

Questions to try

Type them as they are, or change the coin, exchange and dates.

Market

What's the funding on BTC across exchanges right now?
Which coins have the widest spreads between two exchanges at the moment?
Show ETH funding history on Binance for the last week.
What's listing on futures in the next few days?

Your account

Which of my cards made the most today and which lost on fees?
Show my balances and how close I am to liquidation.
Compare my PnL this month with last month.
Where am I on the leaderboard?

Learning

How does the close spread work?
Explain Auto mode like I'm new to arbitrage.
Which permissions should my exchange API key have?

Privacy and control

What the assistant can see

Funding, spreads, listings and your plan usage
Your own cards, trades, PnL, balances and positions
The names of your connected exchange accounts
Your plan, payments and leaderboard place

What it never sees or does

Your exchange API keys
Who other traders are: on the leaderboard they appear as "trader #N"
Anything about Arbitron's servers
Placing orders, starting cards or changing settings

Every lookup counts against your plan's API quota, and one answer can use several. Assistant requests are counted on the "Assistants (OAuth)" row of the AI assistants & API page.

Disconnect one assistant

Remove or disconnect Arbitron in that assistant's connector settings. Other assistants stay connected.

Disconnect every assistant

Open AI assistants & API in the menu. In the "Assistant sign-in" section, find "Assistants (OAuth)" and click "Revoke". Every connected assistant loses access at once. The section appears after your first assistant connects. To use an assistant again after revoking, connect it again.

Connected before September 24, 2026?

Those connections only see market data. Disconnect Arbitron in the assistant and connect again. The approval page should now list reading your own account. If it doesn't, that assistant only asks for market data.

Troubleshooting

The assistant shows no Arbitron tools

Check that Arbitron is switched on in this chat. In ChatGPT, open the app's settings and click "Refresh".

"Couldn't reach" or "connection failed"

Check that the address is exactly https://arbitron.app/mcp. Claude's error message includes a reference that starts with ofid_: send it to Arbitron support.

Sign-in keeps starting over

Clear cookies for arbitron.app or try another browser, then disconnect Arbitron in the assistant and connect again.

A Claude Team member can't find "Add custom connector"

On Team and Enterprise only an Owner can add connectors. Ask them to add Arbitron, then click "Connect" on the entry labeled "Custom".

ChatGPT has no Developer mode

Look in both places: "Settings" → "Security and login", and "Settings" → "Apps" → "Advanced settings". Check that you're on Plus or higher. On a work plan, ask your admin.

ChatGPT says "Something went wrong" after sign-in

Delete the Arbitron app in ChatGPT and create it again.

It says it can't see my account

You may have connected before September 24, 2026, or with an API key. Disconnect, connect again with sign-in, and check that the approval page lists reading your own account. If it doesn't, that assistant only asks for market data.

Rate limited

You've used your plan's requests for the minute or the month (the monthly count resets on the 1st, UTC). Questions about cards, trades, PnL and history also have their own limit of 20 a minute on every plan. Wait a minute, check usage on AI assistants & API, or see Pricing for higher limits.
