Common questions

Is Headless Oracle safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (5.0.0) reached the registry 9 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Headless Oracle

Ed25519-signed market-state attestations for 28 global exchanges.

What It Does

Autonomous trading agents need to know if an exchange is open before executing trades. Headless Oracle answers that question with a cryptographically signed receipt that any agent can verify independently — no trust in the operator required. UNKNOWN states are always treated as CLOSED (fail-closed).

Quick Start

# MCP (Claude Desktop, Cursor, any MCP client)

npx headless-oracle-mcp

REST API — demo receipt (no auth required)

curl https://headlessoracle.com/v5/demo?mic=XNYS

Sandbox key (200 calls, 7 days, no card) - POST with an email

curl -X POST https://headlessoracle.com/v5/sandbox \ -H 'Content-Type: application/json' \ -d '{"email":"you@example.com"}'

Architecture

Single TypeScript Cloudflare Worker. Ed25519 signing via @noble/ed25519. Three KV namespaces (overrides, API keys, telemetry). Two Durable Objects (webhooks, SSE streams). Runs on Cloudflare's edge network - no origin server.

4-tier fail-closed: KV override check -> schedule engine -> UNKNOWN fallback -> unsigned critical failure.

See docs/architecture/overview.md for the full architecture.

API

Four MCP tools - get_market_status, get_market_schedule, list_exchanges, get_payment_options. Receipt verification is REST-only (POST /v5/verify) or offline with @headlessoracle/verify.

The REST surface is enumerated in the OpenAPI 3.1 spec, which is served live and is the list of record. Full references:

REST API Reference
MCP Reference
OpenAPI 3.1 Spec

Exchanges

23 traditional markets (XNYS, XNAS, XLON, XJPX, XPAR, XHKG, XSES, XASX, XBOM, XNSE, XSHG, XSHE, XKRX, XJSE, XBSP, XSWX, XMIL, XIST, XSAU, XDFM, XNZE, XHEL, XSTO) plus 5 extended (XCBT, XNYM, XCBO, XCOI, XBIN). DST handled automatically via IANA timezone names. Lunch breaks, half-days, and holidays for 2026-2027.

Testing

npm test              # the full unit/integration suite

npm run test:smoke # 11 smoke tests against live production

The passing count is published by the worker itself at /v5/metrics/public as tests_passing, and CI fails if that number and the suite disagree. It is not restated here, because a number in a README is a number nothing checks.

Security

Ed25519 signatures on every response. 60-second receipt TTL. Fail-closed architecture (UNKNOWN = CLOSED). Security headers on all responses (HSTS, CSP, X-Content-Type-Options, X-Frame-Options).

See SECURITY.md for the responsible disclosure policy.
