Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.03412 | $0.03412 |
| Opus 5 | $0.01706 | $0.01706 |
| Sonnet 5 | $0.00682 | $0.00682 |
| Haiku 4.5 | $0.00341 | $0.00341 |
Grade A, and why
robinhood-mcp AGENTS.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 4d 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.
How it starts
The opening of the file, as written. The whole thing — 179 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
This file provides guidance to coding agents (Claude Code, Cursor, Codex, etc.) when working with this repository. It is the single source of truth; CLAUDE.md imports it via @AGENTS.md.
Project Overview
robinhood-mcp is a read-only MCP (Model Context Protocol) server that wraps the robin_stocks Python library to expose Robinhood portfolio data as research tools for AI assistants. It is strictly a research/educational tool — no trading functionality is exposed.
Core purpose:
- Translate MCP tool calls into
robin_stocksRobinhood API requests over stdio - Provide read-only portfolio, quote, fundamentals, news, and order-history research
- Support multi-account Robinhood logins (taxable, IRA, etc.) via optional account selection
Read-only is a hard invariant
The server never exposes order placement, cancellation, or any account-modifying call. There are no order_buy_*, order_sell_*, or cancel_* tools, and none should ever be added. Every tool delegates to read-only robin_stocks endpoints (rh.profiles.*, rh.stocks.*, rh.account.* getters, rh.orders.get_all_stock_orders, rh.options.get_open_option_positions). When adding a tool, preserve this invariant; the order-history tool explicitly documents "Read-only — this never places or cancels orders" (tools.py:639).

robinhood-mcp
robinhood-mcp is the console-script entry point, wired to robinhood_mcp.server:main (pyproject.toml:36-37). Python >= 3.11 is required (pyproject.toml:11). Runtime dependencies: fastmcp, robin_stocks, python-dotenv, pyotp (pyproject.toml:21-26).
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.

robinhood-mcp AGENTS.md is an instructions file published in the GitHub repository verygoodplugins/robinhood-mcp (39 stars, last pushed 1mo ago), licensed MIT. It adds 3,412 tokens to every session, about $0.0171 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
