Overview

AI-generated overview

Arbitron gives an assistant read-only crypto perpetual futures market data: funding rates, venue spreads, backtests, listings and usage.

What you can do
  • Search coins and look up funding rates, per-coin funding and funding history
  • Compare current spreads between venues and review backtested spread results
  • Check the listings calendar and the exchanges Arbitron tracks
  • Review your own API usage and plan limits
When to use it
Useful when you want an assistant to answer questions about crypto perpetual futures funding, cross-venue spreads or new listings, or to pull those figures into research and reporting without writing API calls yourself.
Requirements
Remote Streamable HTTP endpoint at arbitron.app/mcp. Interactive clients connect with OAuth 2.1 using an Arbitron account; programs use an Arbitron API key as a bearer token. A free Demo plan exists; paid plans unlock more history and commercial use.
Before you install
Data is read-only, but access is tied to your Arbitron account and API key, so treat the key as a secret. The free Demo plan returns 15-minute delayed data, 50 rows per page and no history. Returned data is subject to Arbitron's terms, and republished figures must be attributed with the source link and timestamp.

Installation

In SourceWeft

  1. Open Arbitron in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/app.arbitron%2Fmcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

README

Arbitron API and MCP server

Read-only market data for crypto perpetual futures across the venues Arbitron tracks: current funding rates, funding history, the spread between two venues right now, the scanner's backtested spreads, and the listings calendar. Two doors to the same data: a REST API for programs and an MCP server for AI assistants.

This repository holds the public artefacts of that product so they can be pinned, diffed and cited. The service itself is closed source.

MCP in one minute

Claude Desktop, Cursor and ChatGPT connect with OAuth 2.1 (sign in with your Arbitron account); a program connects with the same API key as a bearer token. Client configurations are in mcp/clients/. Nine read-only tools: arbitron_search_coins, arbitron_get_funding_rates, arbitron_get_coin_funding, arbitron_get_funding_history, arbitron_get_spreads, arbitron_get_spread_backtest, arbitron_get_listings, arbitron_get_exchanges, arbitron_get_usage.

Plans

The Demo plan is free: 15-minute delayed data, 50 rows per page, no history. Paid plans (Developer, Pro, Business) are live, reach further back, and include commercial use. Details at https://arbitron.app/developers#plans.

Citing

Attribute republished figures as "Data: Arbitron" with a link to meta.url, and keep meta.as_of with the number. Name the exchange and the settlement interval beside any funding rate.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
