Marketcaper MCP

What Marketcaper MCP does

Marketcaper MCP is reached at the endpoint https://marketcaper.com/api/mcp and is listed in the official MCP Registry as com.marketcaper/mcp. It exposes four tools: get_asset_snapshot, compare_assets, compare_assets_pack and get_stock_heatmap. The pack tool returns short copy, citations, canonical URLs and optional hosted image metadata, and the heatmap tool returns summaries with optional hosted PNG images.

It is aimed at social-content agents, Telegram and Discord finance bots, newsletters and research assistants, and its citation rule asks you to cite the returned source_url, canonical_url or citation_text. Public read-only access needs no API key but is limited to 60 requests per minute and 10 hosted images per day per IP, and image requests may take about 20 seconds. The README says it is not a trading system, investment adviser, portfolio monitor or bulk extraction API.

How it fits with Hermes Agent

A general MCP server for MCP-compatible clients; the repository description names Hermes and OpenClaw, but the README shows configuration examples for Cursor, VS Code and Codex CLI and none for Hermes.

Note: Public access is rate limited (the README gives 60 requests per minute and 10 images per day per IP, subject to change), and the service is not a trading system or investment adviser.
