What is openquant CLAUDE.md?

Project instructions for OpenQuant, a service that provides stock research and trading analysis through an MCP server. MCP is a way for an AI agent to call tools provided by another program.

Use them to configure OpenQuant locally and analyse a stock, inspect insider buying or selling, or assess portfolio risk before a trade.

They explain how to connect the server and which analysis tools to use for prices, insider activity, risk, and trade preparation. This reduces guesswork when setting up or using the trading tools.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.01636	$0.01636
Opus 5.5	$0.00654	$0.00654
Sonnet 5.5	$0.00327	$0.00327

Security

Grade A, and why

openquant CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

92% identical to openquant AGENTS.md — 12 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

OpenQuant — Claude Code Instructions

This file tells Claude Code how to use OpenQuant's trading tools via the MCP server.

MCP Server Connection

OpenQuant exposes an MCP server with SSE transport. Start it with:

pip install openquant-cli[mcp]
openquant-mcp

The server runs at http://localhost:8000/sse by default.

Claude Code MCP Config

Add to your .claude/settings.json or project .mcp.json:

{
  "mcpServers": {
    "openquant": {
      "url": "http://localhost:8000/sse",
      "transport": "sse"
    }
  }
}

If running locally with stdio transport instead:

{
  "mcpServers": {
    "openquant": {
      "command": "openquant-mcp",
      "transport": "stdio"
    }
  }
}

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
