Summary
This connects AI agents to live prediction market infrastructure on Kalshi and Polymarket. You get 40 tools covering world state queries, market inspection, orderbook data, and trading operations. It's a compatibility layer over SimpleFunctions CLI, which is the actual product center here. The MCP endpoint exists for Claude Desktop and similar hosts, but if you're scripting or building services, you want the CLI itself (sf status, sf world, sf inspect) or their HTTP API. Reach for this when you need an LLM to query market odds, discover contracts by quality signals, or inspect specific tickers as part of a reasoning loop. The underlying CLI exports structured JSON and keeps execution explicit.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.

SimpleFunctions CLI (sf)
Reference and issue mirror for @spfunctions/cli, the supported SimpleFunctions command-line interface for prediction-market infrastructure.
The current CLI is distributed through npm. Install the package and treat the installed sf binary as the source of truth:
npm i -g @spfunctions/cli
sf login
sf status --json
sf world --json
sf describe --all --json
sf is the primary local surface for SimpleFunctions. It queries live Kalshi + Polymarket state, inspects markets and orderbooks, exports structured JSON for coding agents, runs thesis and portfolio workflows, and keeps execution commands explicit and permission-gated.
What this repository is
- Public reference page for the npm package.
- Issue tracker for
@spfunctions/cli. - Installation, support, and discovery pointer for the current
sfsurface.
What this repository is not
- It is not the current full operator-runtime source tree.
- It is not the canonical command inventory.
- It should not be used to infer current command counts, market counts, or execution behavior.
Use sf describe --all --json for the installed command manifest. Use https://simplefunctions.dev/api/internal/statistics for current public surface counts.
First useful workflow
sf status --json
sf world --json
sf discover --quality --json
sf inspect <ticker> --json
If a command is unavailable in your installed version, run:
npm i -g @spfunctions/cli@latest
sf describe --all --json
Product surface order
- CLI: primary local control plane for humans, shell scripts, cron, Claude Code, Codex, and other coding agents.
- HTTP/Data API: network surface for services, dashboards, notebooks, and remote workers.
- SDKs and agent runtime: planned wrappers over stable CLI/API object contracts.
- MCP: compatibility adapter for MCP-only hosts, not the canonical product center.
