  • query_signalsGeolocated world events from global news media, AI-enriched with severity/GEOINT scores and collection recommendations.
  • query_statsRoll-ups over the corpus: totals plus per-category and per-day breakdown. `total` counts the same events query_signals returns, so it matches its meta.total_count for the same query.
  • query_hotspotsWhere activity concentrates: density grid-binned into ranked cells with peak severity, categories and representative event_ids. Events too coarse to place are counted in meta.dropped_by_plottable_count, not spread over the grid.
  • get_world_briefAI world brief: daily (prior UTC day, all plans) or weekly/monthly by plan. freshness.is_stale: no newer day, so relay as stale.
  • get_usageThe calling key's remaining token balance and plan capabilities. Pre-flight a metered call with it.
  • search_imagerySearch the imagery catalog over an area and window. Metadata only, no pixels. eventDate tags each scene pre/post — **a same-day scene is same_day_unknown, never post** — and eventPoint/eventAoi add target_relation, so a scene that only clips the bbox is not read as covering the event.
  • plan_event_imageryThe deterministic imagery plan for ONE event: checks BOTH sensors exactly once — sentinel-1-grd (SAR, the only look that survives cloud and night) and sentinel-2-l2a — against the event footprint and a pre/post window. **A VHR recommendation never invalidates what the free catalog showed.**
  • rank_imaging_priorityWHERE, and with what class of satellite, observation is most worthwhile now: composite IMPORTANCE crossed with the SPEC CLASS the required resolution demands — coarse, hr (free Sentinel-class) or vhr. Deterministic.
  • survey_observable_eventsWhich events a sensor can actually RESOLVE, over the FULL set. **The population is ungated by tasking readiness**, so its total sits above rank_imaging_priority and counts a different unit from query_signals clusters.
  • predict_satellite_passesWHEN a place can next be imaged and by WHAT: 13 free-systematic and commercial-taskable families. **Every pass is a GEOMETRIC access opportunity** — no operator plan is consulted. retrieval_ok:false means timing is UNAVAILABLE, never "no passes".
  • assess_signalAI remote-sensing deep-dive for one signal: what to observe, sensors, a collection window. Also returns a deterministic `context` whose `imagery_handoff.parameters` are the exact search_imagery inputs. Cached per signal; not-observable signals are rejected before any charge.
  • ask_analystAsk the Delta Analyst an OSINT/GEOINT question; returns a structured brief. **Durable async**: {status:"processing", job_id} comes back immediately and the run finishes in a background worker. Fetch with get_analyst_job, or re-send the SAME idempotencyKey (no second charge).

Frequently asked questions

Geomelon MCP is categorized under Location Services and uses a local stdio subprocess. Offnadir Delta MCP belongs to Location Services and uses a local stdio subprocess. Pick Geomelon MCP for location services work and Offnadir Delta MCP for location services.

Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.

Geomelon MCP is listed as freemium — a free tier with paid plans. Auth: api key required. Offnadir Delta MCP is listed as freemium — a free tier with paid plans. Auth: other. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.

Yes. MCP clients support multiple servers: add 930m310n-geomelon-mcp and off-nadir-lab-offnadir-delta-mcp as separate keys in the same mcpServers object, and your assistant will call tools from either one.
