List every app (project) in your Crossdeck portfolio that this connector can read — the same set your Pulse dashboard shows. Returns an array of { id, name } per app. Call this FIRST when a workspace key (cd_wk_) is connected, then pass an id to other tools or set a default with use_project. With a single-app key it returns just that one app. Read-only; takes no arguments.

Set the current app for this conversation so later tools default to it without repeating project. Behaves as session state: it persists until you call this again and applies to every subsequent tool call. Returns { currentProject } — the project id now in effect. Use when the user says 'switch to ' or names an app to focus on; call list_projects first for valid ids. No effect with a single-app key (the project is fixed).

Get an app's recurring revenue from its maintained revenue ledger (a point-read, never a scan). Returns MRR in cents, the paying-customer count, and the per-rail split across Stripe, Apple, and Google; with granularity='day' it adds a daily time series over the window. Use for 'what's our MRR', 'how many paying customers', or revenue-trend questions. An app with no revenue yet returns zeros, not an error.

Get an app's database read-cost over the last days days, split into per-user reads vs un-attributed overhead, plus a breakdown by operation. Per-user attribution works because Crossdeck joins read-cost to the SDK's identity, so you can see which operations drive the bill. Returns the per-user-vs-overhead totals and the by-operation breakdown. Use for 'what's driving our database reads' or 'which operation costs the most'.

For one error (by fingerprint/issue id), get its blast radius joined to identity. Returns distinct users affected, how many of those are PAYING customers, and the error's type, status, occurrence count, and first/last-seen timestamps — counts only. Use to size an error's impact. For the NAMED paying users behind the counts (and their revenue at risk), call get_error_affected_users instead.

For one error (by fingerprint), get the PAYING users it actually hit — the row-level moat answer: which paying customer broke, and how much are they worth. Returns a list sorted by revenue at risk (highest first), each row with your own user id, monthly revenue in cents, and when they last hit the error. Joins the error layer to identity and revenue. Returns only your own identifiers — never emails or names you didn't provide. Use when you need the actual customers, not just the counts from get_error_impact.

Cross-match one customer across every layer Crossdeck joins by identity. Returns what they pay (monthly cents), their active entitlement count, and their database read-cost — in one view. Identify the person by ANY ONE of the identifiers below; they all resolve to the same canonical customer. Use for 'how much does this user pay and what do they cost us?'. If no customer resolves, returns a no-match result, not an error.

Get headless web analytics for one host/subdomain the app owns (e.g. a tenant's subdomain). Returns page views and unique visitors with totals; granularity='day' adds a daily series. The host MUST be a verified origin of the project, or the request is rejected (403). Use for per-tenant or per-subdomain traffic questions.

Get the top pages or top referrers for one host the app owns, ranked and paginated. Returns rows of { key, views } highest-first, where key is a page path (default) or a referrer. Set dimension='top_referrers' for traffic sources. The host must belong to the selected app. Use for 'most-viewed pages on this subdomain' or 'where its traffic comes from'.

Render an interactive line chart of unique visitors and page views over time for a host you own, and return the period totals as text. Returns a rendered chart in MCP-Apps-capable hosts (a text summary elsewhere) plus the totals. Use when asked to chart, graph, draw, or visualize growth or traffic for a subdomain. The host must be a verified origin of the project, or the request is rejected.

Render a customer's cross-layer dashboard — what they pay (monthly), their active entitlements, and their database read-cost, joined by identity — and return the same as a text summary. Returns a rendered dashboard in MCP-Apps-capable hosts (a text summary elsewhere). Identify the customer by ANY ONE of the identifiers below; they all resolve to the same canonical customer. Use when asked to show, open, or visualize a customer's full picture. Returns a no-match result if no customer resolves.
