The Spice Melange Trading Desk: DeepBook market data connector — questions

Answers built from our own checks of this server.

What can The Spice Melange Trading Desk: DeepBook market data connector do?

It exposes 31 tools, read directly from the server on our last check. Among them: build_bm_deposit_tx, build_bm_withdraw_tx, build_cancel_order_tx, build_create_balance_manager_tx, build_limit_order_tx, build_swap_tx and 25 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 The Spice Melange Trading Desk: DeepBook market data connector mostly used for?

Its tools cluster around build, template and pool. 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 The Spice Melange Trading Desk: DeepBook market data connector working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 92 checks got a reply (98.9%), average response time 650 ms. The bar chart above shows every period we have measured.

Is The Spice Melange Trading Desk: DeepBook market data connector 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 The Spice Melange Trading Desk: DeepBook market data connector?

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 The Spice Melange Trading Desk: DeepBook market data connector need an API key?

No. The Spice Melange Trading Desk: DeepBook market data connector completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 31 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is The Spice Melange Trading Desk: DeepBook market data connector?

It answers our handshake in 650 ms on average, which is faster than 15% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
