Marketcaper MCP missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

compare
compare_assets
Compare two Marketcaper assets and return the live what-if market cap scenario, canonical pair URL, and optional hosted image URL. Hosted images are PNG, generated on demand, share a 10 images/day/IP limit, and may require a longer timeout than the MCP JSON call. Always cite the returned source_url when using the data.
compare_assets_pack
Compare two Marketcaper assets and return the same cited comparison data plus a ready-to-publish short post and share payload with the hosted comparison image URL. Always cite the returned source_url when using the data.
asset
get_asset_snapshot
Resolve one Marketcaper asset and return its live market cap snapshot. Always cite the returned source_url when using the data.
stock
get_stock_heatmap
Return a current Marketcaper stock heatmap summary plus a hosted dark-theme PNG image URL. Supports US or global universes, classic or bubble views, optional sector/category filtering, and capped summary rows. Hosted images share a 10 images/day/IP limit. This is not a bulk feed extraction tool.

Marketcaper MCP — questions

Answers built from our own checks of this server.

What can Marketcaper MCP do?
It exposes 4 tools, read directly from the server on our last check. Among them: compare_assets, compare_assets_pack, get_asset_snapshot, get_stock_heatmap. 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 →
Is Marketcaper MCP 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 259 ms. The bar chart above shows every period we have measured.
How do I connect Marketcaper MCP?
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 Marketcaper MCP need an API key?
No. Marketcaper MCP completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Marketcaper MCP?
It answers our handshake in 259 ms on average, which is faster than 56% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
