Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).
claude mcp add --transport http trkr 'https://www.trkr.ai/api/mcp'

"mcpServers": {

TRKR agents
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 that learns from three decades of macro history and two decades of asset prices. 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.
Install (Claude)
/plugin marketplace add trkr-ai/trkr-agents
/plugin install trkr
Then set your API key, which you can create at trkr.ai/app/agents:
export TRKR_API_KEY=trkr_sk_...
Or, without the plugin, point any MCP client at the endpoint directly:
claude mcp add --transport http trkr https://www.trkr.ai/api/mcp \
--header "Authorization: Bearer $TRKR_API_KEY"
ChatGPT
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.
- Turn on developer mode in ChatGPT's settings. OpenAI has moved this between Security and login, Connectors → Advanced settings and Apps → Advanced, so follow their help article rather than a path written here. It is on chatgpt.com only (not the mobile app), needs a paid plan, and on a Business or Enterprise workspace an admin must allow custom connectors first.
- Create a connector pointing at
https://www.trkr.ai/api/mcp, authentication OAuth. - You will land on trkr.ai to sign in and approve the connection, then return to ChatGPT with the tools available.
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.
Google Antigravity
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.
curl -fsSL https://antigravity.google/cli/install.sh | bash
agy install
Then, one command — flags must come before the name, and an http URL is
detected without --type:
agy mcp add --header "Authorization: Bearer $TRKR_API_KEY" \
trkr https://www.trkr.ai/api/mcp
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:
{
"mcpServers": {
"trkr": {
"serverUrl": "https://www.trkr.ai/api/mcp",
"headers": { "Authorization": "Bearer trkr_sk_..." }
}
}
}
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.
What you can ask
- "Why does future #42 crash in 2031?" — it reads the regimes, macro paths and prices behind that specific simulation.
- "Critique 60/30/10 SPY/AGG/GLD." — run through every future at once, with the outcome distribution rather than a single backtest.
- "Build something for a client retiring in five years." — co-build the allocation, then test it.
- "Is this data credible?" — the quality scorecard, per asset, rather than an assurance.
What's in here
trkr/.mcp.json | The MCP server: eight 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.

Frequently asked questions
What is io.github.trkr-ai/trkr?
Stress-test portfolios against hundreds of regime-aware simulated futures for real markets.
How do I install io.github.trkr-ai/trkr?
It runs as a remote server. In Claude Code: claude mcp add --transport http trkr 'https://www.trkr.ai/api/mcp'. For other clients, paste the JSON configuration from this page into their MCP settings.
Does io.github.trkr-ai/trkr need an API key?
Its registry entry lists no required key or secret. Some features may still need an account with the service it connects to.
Is io.github.trkr-ai/trkr open source?
Its code is public on GitHub, but the repository does not declare a standard license.
Who maintains io.github.trkr-ai/trkr?
It is published by trkr-ai. AI.tn lists it but does not maintain or endorse it.
From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
