MCP · v0

DexRay as a tool.

A read-only Model Context Protocol server over Streamable HTTP (protocol revisions 2025-06-18 / 2025-11-25 — what today's Claude and ChatGPT connectors speak). Add it as a custom connector and ask about a game, a wallet, or the house strategy — no API key, free-tier data only.

Endpoint

https://dexray.org/mcp

Streamable HTTP, JSON-RPC 2.0. No auth for v0 — every tool reads the same free-tier data already public on the site.
Stateless: no session id is assigned, and no server-initiated stream — every request gets a single JSON response.
Modest per-IP rate limit. 429s carry a Retry-After header; back off and retry.

Add it to Claude

claude.ai → Settings → Connectors → Add custom connector.
Name it DexRay, paste the endpoint URL above, leave auth off.
Enable it in a chat and ask something like “what’s the consensus line on BUF/HOU” or “show me DexRay’s house strategy gate”.

Add it to ChatGPT

Enable developer mode (Settings → Connectors → Advanced → Developer mode), or use a custom connector where offered.
Add a connector, paste the endpoint URL above, no auth.
Reference it in a chat the same way as any other connector tool.

Data & license

Every tool returns DexRay’s own derived values — de-vigged consensus medians and n_books counts, our CLV grades and verdicts, public Polymarket data. Raw per-book odds quotes are licensed from our odds provider and are never returned by any tool, in bulk or otherwise — the same boundary drawn on /data. Output is CC BY 4.0 with attribution to dexray.org. Snapshots, not a live feed — see methodology for refresh cadences.

Full REST access (auth, higher limits, model lines) is the /api/v1 product; this server is the free, no-key surface for LLM assistants.
