Connect your own AI assistant to TRKR's synthetic market data.
TRKR simulates hundreds of complete alternative futures for real assets — every one a full ten years of daily prices, anchored to today's market and generated by a regime-aware, macro-driven engine calibrated against two decades of history. This plugin lets Claude query that data directly; ChatGPT and any other MCP client can reach the same endpoint (see below).
The simulations stay on TRKR's servers; the thinking happens in the assistant you already pay for. TRKR sends small, reduced answers — quantile bands, summary statistics, downsampled series — never the raw grid. That keeps your context small and your bill low.
Then set your API key, which you can create at trkr.ai/app/agents:
Or, without the plugin, point any MCP client at the endpoint directly:
ChatGPT cannot send an API key to an MCP server — OpenAI's connectors support OAuth only — so it signs you in instead. There is no key to copy.

OAuth.The skill in this repo is a Claude format, so a ChatGPT connector does not
install it. The same rules travel in the server's own instructions, which
ChatGPT reads at connection time — but if you use TRKR in a ChatGPT Project,
pasting trkr/skills/reading-synthetic-markets/SKILL.md into the project's
custom instructions is the closest equivalent.
Gemini CLI was retired in June 2026 and replaced by Antigravity (the agy
command). The consumer app at gemini.google.com still has no way to add a
connector, so Antigravity is the route for Google users — and it is free.
Then, one command — flags must come before the name, and an http URL is
detected without --type:
Or write it to ~/.gemini/config/mcp_config.json yourself (.agents/mcp_config.json
for one workspace). The field is serverUrl; Antigravity rejects the url and
httpUrl spellings Gemini CLI used, and the wrong one fails as though the server
were down:
Drop the header entirely and Antigravity handles OAuth by itself — it registers dynamically and sends you to trkr.ai to approve, the same flow ChatGPT uses.
trkr/.mcp.json | The MCP server: seven tools over the current run |
trkr/skills/reading-synthetic-markets/ | How to read an ensemble without drawing false conclusions — the spread vs the median, unit conventions, and why filtering futures by realized returns invalidates a benchmark comparison |
The skill matters as much as the tools. Simulated ensembles invite a specific class of confident, wrong conclusion, and the skill is what stops your assistant producing them.
