The full upstream README, mirrored here for reference. Install config, tool schemas, adoption signals, and an original overview live on the Offnadir Delta MCP listing page.
From first signal to satellite evidence. Give an AI agent a live intelligence workflow: discover an event, verify the reporting, identify what evidence is missing, determine whether a satellite can actually resolve it, and produce a collection-ready plan.
Real-time event and geospatial intelligence for OSINT, geopolitical risk, and GEOINT work — source-linked, geolocated, and current, not a training snapshot.
42 tools · MCP server version 1.31.0 · full reference
Seeing the event is easy. Knowing what you can prove — and what evidence is still missing — is the product. Delta:
No install. Point any MCP client at the remote endpoint and approve once over OAuth 2.1 (Dynamic Client Registration is supported, so most clients need only the URL):
In the Claude or ChatGPT apps: Settings → Connectors → Add custom connector, paste that URL. Cursor and VS Code have one-click installs on the docs page.
Claude Code:
Use this when your client cannot do remote OAuth, or you would rather hold an API key in an environment variable and pin a version. Get a key at offnadir-delta.com/account/api.
Docker:
The package forwards tools/call to the hosted server with your key. tools/list answers
locally from a generated catalog, so registries can introspect it without credentials.
23 of the 42 tools cost nothing, so the first thing you run is free:
Give me the latest Daily World Brief. Lead with the three most significant developments, explain why each matters, and cite the supporting signals.
Then try the full signal-to-satellite workflow:
Find the highest-priority observable event from the last 24 hours, verify the reporting, and recommend the best available satellite collection plan.
What is happening, where it concentrates, and what today looks like.

get_world_brief | The Daily World Brief — an AI digest of the previous UTC day. | free |
query_developments | What actually CHANGED about the events in an area, not which articles are new. | 3 tok |
get_event_thread | One event end to end: state plus every change in order — the "new event or update" distinction a feed cannot make. | free |
search_entities | Find a place in the location registry — ports, bases, airfields, power plants, chokepoints, named seas. | 1 tok |
get_entity | What has happened at one place: the registry record plus every linked event with HOW it was linked. | 1 tok |
get_related_events | What else connects to one event, and what came before and after. | 3–8 tok |
Whether a satellite can resolve it, which one, and when it next passes.
| Tool | What it does | Cost |
|---|---|---|
search_imagery | Search the imagery catalog over an area and window. | 2 tok |
plan_event_imagery | The 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. | 4 tok |
rank_imaging_priority | WHERE, 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. | 1 tok |
survey_observable_events | Which events a sensor can actually RESOLVE, over the FULL set. | 1 tok |
predict_satellite_passes | WHEN a place can next be imaged and by WHAT: 13 free-systematic and commercial-taskable families. | 2 tok |
test_hypotheses | Given competing statements, the observation that would REFUTE the most — and those that would refute none. | 3 tok |
lookup_elevation | Terrain height from the Copernicus DEM GLO-30 for a point, bbox or polygon, with relief — the number that governs SAR layover and shadow. | free |
analyze_terrain | Compute FROM the terrain. | free |
Turn reporting into a cited assessment you can audit afterwards.
| Tool | What it does | Cost |
|---|---|---|
assess_signal | AI remote-sensing deep-dive for one signal: what to observe, sensors, a collection window. | 5/15 tok |
ask_analyst | Ask the Delta Analyst an OSINT/GEOINT question; returns a structured brief. | 5–123 tok |
get_analyst_job | Status and result of an ask_analyst run. | free |
query_claims | The ledger of claims this key was given, each with its evidence class, independent source families and publishers. | free |
refine_location | Research one signal's location further and store a better coordinate if the sources genuinely narrow it. | 3–29 tok |
measure_index_series | Measure a spectral index over an area scene by scene through the Sentinel-2 archive. | 0.5 tok |
detect_ships | Count vessel-like targets in ONE Sentinel-1 SAR scene by CFAR detection — radar sees through cloud and at night. | 5 tok |
Stand up continuous coverage and be told only when the answer changes. Creating and listing cost nothing — you are metered only when a check actually fires, or a new acquisition is actually measured.
| Tool | What it does | Cost |
|---|---|---|
create_standing_order | Put an area under CONTINUOUS watch: a question plus a bbox, re-answered on a schedule, notifying only when the answer changed. | free |
list_standing_orders | The standing orders on this key: cadence, area, last check, last actual fire, and quiet_checks — a high quiet_checks means the watch is not earning its place. | free |
delete_standing_order | Delete a standing order, or pause/resume with active=false/true. | free |
list_monitored_areas | Places under continuous satellite measurement: metric, latest value, change, anomaly flag, coverage. | free |
get_monitored_area | One monitored area with its full measurement history. | free |
create_monitored_area | Put a place under continuous satellite measurement — every new Sentinel-1/2 or VIIRS acquisition is measured. | free |
list_watches | The Watchlist as one list, each entry with a state bucket. | free |
get_watch | One watch end to end: target, state, latest change, measurements with recent series, standing-order questions, and for an event watch its verification state, developments and thread, plus this account's notes. | free |
get_decision_package | Everything needed to decide what to collect next about one watch, in one object. | 5 tok |
create_watch | Add a target to the Watchlist. | free |
update_watch | Rename, pause or resume a watch. | free |
delete_watch | Delete a watch and its underlying resources — bound monitored areas with their history, and standing orders. | free |
add_note | Add a note to a watch, start a thread, or reply. | free |
delete_note | Delete one note from a watch. | free |
The map assets you own — saved layer sets and your own uploaded data.
| Tool | What it does | Cost |
|---|---|---|
list_layer_sets | The layer sets saved on this account. | free |
get_layer_set | One saved layer set by id. | free |
list_uploaded_layers | The data this account uploaded to the map, plus the formats the uploader accepts. | free |
Pre-flight your token balance before a metered call.
| Tool | What it does | Cost |
|---|---|---|
get_usage | The calling key's remaining token balance and plan capabilities. | free |
Usage-based Delta tokens, identical over REST and MCP. Costs above are generated from the same constant the biller reads, and every metered result carries the exact charge it incurred — so you never have to trust a number in a README. Free tools never touch the balance.
ask_analyst is hybrid-async: it enqueues a run and returns a job_id immediately; poll
get_analyst_job (free — the run is charged once, on completion). Most questions finish in
~30–90s; a brief with satellite-imagery lookups or many sources can take 2–3 minutes.
The API and the MCP server are available on every plan, including Free — the only gate is
your token balance. Call get_usage (free) to pre-flight. Current limits and package prices:
offnadir-delta.com/pricing.
Two credentials are accepted on the hosted endpoint:
Authorization: Bearer ond_...) — for servers, CI, and this stdio packageKeys are shown once at creation, hashed at rest, and revocable at any time from /account/api.
