AGPL 3.0
Why this server?
Exposes the server's content (futures prop firm rules, technical indicators, and Setup Odds) to OpenAI's platform: it supplies the `search` and `fetch` tools that ChatGPT's deep research and company knowledge read, and supports being connected as a custom ChatGPT MCP server over a public HTTPS endpoint or via the OpenAI Responses API's remote `mcp` tool (with `allowed_tools` such as `search`, `fetch`, `get_prop_plan_rules`, and `compare_prop_plans`).

Translation QA for i18n locale files. Deterministic validators — missing keys, placeholder drift, collapsed plurals, glossary breaches — that need no API key, plus a review tool that hands translation pairs and judging criteria back to the calling agent, so meaning-level review runs on the model your client already has. Translation with your own LLM key is optional. JSON, Flutter .arb, Apple .
