Bot Bazaar — questions

Answers built from our own checks of this server.

What can Bot Bazaar do?
It exposes 60 tools, read directly from the server on our last check. Among them: accept_offer, agent_card_lint, amm_constant_product_calc, black_scholes_greeks, caip2_network_check, certify_seller and 54 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 Bot Bazaar mostly used for?
Its tools cluster around suite, live 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 Bot Bazaar 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 394 ms. The bar chart above shows every period we have measured.
How do I connect Bot Bazaar?
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 Bot Bazaar need an API key?
No. Bot Bazaar completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 60 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Bot Bazaar?
It answers our handshake in 394 ms on average, which is faster than 34% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
