What the publisher says
From the Prism — Crossdeck repository's README, as published. We do not edit it. Read it on GitHub
Prism — Crossdeck's intelligence layer for AI
Ask your app anything — revenue, errors, database read-cost, growth — in plain English, and get rendered charts and dashboards back.
"Which paying customer did this crash hit, and how much revenue is at risk?" — one question, answered across error, identity, and revenue. No single-layer tool can do that.
What Prism does → · Developer docs · Crossdeck
Why Prism is different
Most MCP servers are a connector to one system. Prism is an intelligence layer over your whole app — because Crossdeck already joins the layers about your users (identity · revenue · entitlements · errors · analytics · database read-cost) into one source of truth, by identity.
The point isn't "let AI read my data." It's the crossing: one question can span layers no other tool joins —
"This error a1b2c3 — who did it hit, and how many of them pay us?"
→ the named paying users behind the crash, each with their monthly revenue at risk, sorted by what's on the line.
That's the moat sentence. Prism gives it a voice in Claude, ChatGPT, Cursor, or any MCP client.
Permissions & data access
Secure, read-only access to your live Crossdeck workspace. Prism reads; it never writes.
Prism can see (the layers Crossdeck already owns about your app):
Row-level customer identity is returned only when your connection was explicitly granted that scope — otherwise Prism answers from aggregates and tells you so. That boundary is enforced by Crossdeck, not left to the model.
Prism cannot create, modify, delete, or configure anything in your projects. There is no write path — every tool is read-only (readOnlyHint: true). Ask it to change something and it will tell you it can't.
Data is fetched live at question time over an OAuth-protected endpoint; the connector stores nothing.
Connect in 60 seconds
Remote (recommended) — one-click OAuth, no keys to paste
Prism is a hosted, OAuth-protected MCP endpoint:
https://api.cross-deck.com/mcpAdd it as a connector in your client, sign in with your Crossdeck account, pick a project, and approve. That's it — the client receives a short-lived, scoped workspace credential automatically.

- ChatGPT: Settings → Connectors → Add → paste the URL.
- Cursor: Settings → MCP → Add → paste the URL.
Or open your dashboard at app.cross-deck.com → Developers → Prism → Connect AI for one-click "Add to Claude / ChatGPT / Cursor".
Local (Claude Desktop / Cursor / Claude Code) — stdio + a secret key
No install step — npx fetches the package and its dependencies on each launch, so it self-heals and stays current (nothing local to go stale):
Shortened. The full README is on GitHub.
Nothing above is checked by us. What we check is on the safety report.
