Stock market data your agents can reason with.

Integrate StockContext into this project so you can pull US stock and ETF context from an agent.

Step 1: Read the canonical skill
Read https://stockcontext.com/SKILL.md and follow it. If you cannot access it,
continue with the instructions below.

Step 2: Understand the project
If this is an existing codebase, inspect the language, framework, package
manager, environment-variable conventions, MCP/agent config, and current
market-data or finance code. Ask what stock-market workflow StockContext should
support unless I only asked you to connect MCP.

Step 3: Add hosted MCP
Endpoint: https://api.stockcontext.com/mcp
Header:   X-API-Key: $STOCKCONTEXT_API_KEY
Store the key in the project's normal secret/env system. Do not commit it.

Claude Code:
claude mcp add --transport http StockContext https://api.stockcontext.com/mcp \
  --header "X-API-Key: $STOCKCONTEXT_API_KEY"

Generic MCP JSON:
{
  "mcpServers": {
    "StockContext": {
      "url": "https://api.stockcontext.com/mcp",
      "headers": { "X-API-Key": "$STOCKCONTEXT_API_KEY" }
    }
  }
}

Step 4: Verify
Confirm the stockcontext_* tools loaded. Then call stockcontext_snapshot with:
{ "symbol": "AAPL" }

The response should include { "data": ... }, freshness, and as_of. If it
fails, diagnose the key/header/env/client config before trying other tools.

Step 5: Usage rules
MCP is read-only. REST/OpenAPI is the source of truth. Default sequence:
search if the user gave a company name, then coverage, then snapshot. Add
deeper routes only when needed. Preserve freshness, as_of, units, signs,
unsupported reasons, and unavailable/null explanations. Never invent data.
