Capabilities
What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

This code can reach further than it looks
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

It exposes 26 tools, read directly from the server on our last check. Among them: api_reference, bitcoin_treasuries, company_financials, corporate_events, cot_positioning, crypto_market and 20 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
What is XOOMAR market data mostly used for?
Its tools cluster around insider, fund and short. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is XOOMAR market data working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 421 ms. The bar chart above shows every period we have measured.
How do I connect XOOMAR market data?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does XOOMAR market data need an API key?
No. XOOMAR market data completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 26 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is XOOMAR market data?
It answers our handshake in 421 ms on average, which is faster than 30% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use XOOMAR market data?
The npm package xoomar-mcp was installed 80 times in the last week. Week over week that is -17%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is XOOMAR market data open source?
The code is open source: it is published under the Apache-2.0 licence, written in TypeScript and 1 stars on GitHub. The licence covers the code in the repository, not the hosted service at xoomar.com, which runs on its operator's own terms.
