Quantustik API & MCP server for AI agents

A public, read-only JSON API for Quantustik's quantum-model forecasts and market-aware signals — no API key required to start. Every signal response includes verdict, conviction, an explicit entry/stop/take-profit plan, and the CI90 forecast band. OpenAPI 3.1 schema at https://quantustik.com/api/v1/openapi.json.

MCP server for AI agents

Quantustik also runs a hosted MCP (Model Context Protocol) server at https://quantustik.com/mcp (streamable-HTTP, no API key required to start) so Claude and other MCP-compatible agents can call get_signal, get_forecast, get_market_indicators, scan_universe, get_correlation_map, and related tools directly — grounded, risk-first data with the uncertainty attached, so an agent can't over-claim on a user's behalf. The hosted endpoint is the only transport we operate: there is nothing to install and no local process to run. Every keyed response carries X-Quota-Remaining / X-Quota-Limit headers; anonymous callers get 1000 requests/hour, free API keys get 20,000/day. See API add-on plans for higher quota tiers.

Install in your MCP client

No API key is required to start — anonymous access is rate-capped at 1000 requests/hour per IP; a free key raises that to 20,000/day. Every client below points at the same hosted endpoint, https://quantustik.com/mcp.
