README 快速开始

Marketcaper MCP

Marketcaper MCP gives AI agents fresh market data and something worth posting: cited cross-asset comparisons, asset snapshots, ready-to-publish comparison packs, and hosted stock heatmap images.

It is built for social-content agents, Telegram and Discord finance bots, newsletters, research assistants, and coding assistants that need current, source-linked finance context.

Docs: https://marketcaper.com/mcp
MCP endpoint: https://marketcaper.com/api/mcp
Server card: https://marketcaper.com/.well-known/mcp/server-card.json
Website: https://marketcaper.com

No API key is required for public read-only MCP access. Rate limits apply to protect the service.

What it is good for

Create cited BTC vs ETH, NVDA vs AAPL, or USD vs BTC comparison posts.
Generate Telegram or Discord finance bot replies with canonical Marketcaper source links.
Build newsletter sections with comparison images and stock heatmap visuals.
Let research assistants answer cross-market size questions without relying on stale model memory.
Produce market recap cards with hosted PNG images.

What it is not for

Marketcaper MCP is not a trading system, investment adviser, portfolio monitor, backtesting engine, technical-analysis feed, news feed, or bulk extraction API. Do not use it to scrape all assets, power high-frequency workflows, automate trades, or monitor portfolios.

Tools

The public MCP server currently exposes:

get_asset_snapshot - resolve one asset and return current size context with source links.
compare_assets - compare two assets on one size scale.
compare_assets_pack - generate a content-ready comparison pack with short copy, citations, canonical URLs, and optional hosted image metadata.
get_stock_heatmap - return stock heatmap summaries and optional hosted heatmap image metadata.

See docs/tools.md for input and output guidance.
