Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

StockFloc is the most visual stock watchlist, an app where performance is temperature: any US stock that moves 10% or more in a day catches fire (a big gain) or freezes into ice (a big loss). These read-only tools return today's fire and ice movers and the Floc Heat Index, a 0 to 100 daily market-breadth gauge. They return ticker symbols, percent changes and counts only: no share prices, no quotes for a specific ticker, and no recommendations. Data is derived from a commercially licensed feed delayed about 15 minutes and is for information and entertainment only, not investment advice. More at https://stockfloc.com/hot.

get_market_heat — Get the StockFloc market heat

Advertised by the server during the last successful anonymous check.

Advertised read-only

Today's StockFloc Floc Heat Index, a 0 to 100 daily market-breadth gauge (50 is neutral; above 50 the market ran hot, below 50 it froze), plus how many of the most-traded US stocks are on fire (up 10% or more) versus frozen (down 10% or more). Use this when someone asks how hot or cold the stock market is today, or how many stocks made big moves. US stocks only, delayed about 15 minutes; returns the index and counts, not prices.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http stockfloc-mcp https://api.stockfloc.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add stockfloc-mcp --url https://api.stockfloc.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable stockfloc-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "stockfloc-mcp": {
      "url": "https://api.stockfloc.com/mcp"
