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.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

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.

Agent Margin Router — questions

Answers built from our own checks of this server.

What can Agent Margin Router do?
It exposes 53 tools, read directly from the server on our last check. Among them: agent_wallet_snapshot, arxiv_search, best_price, contract_info, crypto_ohlcv, currency_convert and 47 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 Agent Margin Router mostly used for?
Its tools cluster around web, dns and defi. 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 Agent Margin Router working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 283 ms. The bar chart above shows every period we have measured.
Is Agent Margin Router still maintained?
The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.
How do I connect Agent Margin Router?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Agent Margin Router need an API key?
No. Agent Margin Router completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 53 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Agent Margin Router?
It answers our handshake in 283 ms on average, which is faster than 52% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
