Installation

In SourceWeft

  1. Open Off-Nadir Delta in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Other MCP clients

Add this to your client's mcpServers config.

README

Off-Nadir Delta MCP

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.

What it does

Seeing the event is easy. Knowing what you can prove — and what evidence is still missing — is the product. Delta:

  • monitors emerging world events and geolocates them
  • checks claims against source-linked open data, and reports the source breadth behind each one
  • assesses whether the event is observable from space, at what resolution, and by which sensor
  • returns a collection-ready recommendation: what to collect, where, and when

Connect

Hosted server — recommended

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):

https://offnadir-delta.com/api/v1/mcp

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:

bash
claude mcp add --transport http off-nadir-delta https://offnadir-delta.com/api/v1/mcp

This package — local stdio

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:

bash
docker run -i --rm -e OFFNADIR_DELTA_API_KEY=ond_... offnadir-delta-mcp

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.

First call — free

21 of the 35 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.

Tools

Discover

What is happening, what changed, and what today looks like.

ToolWhat it doesCost
query_signalsGeolocated world events from global news media, AI-enriched with severity/GEOINT scores and collection recommendations.3 tok
get_world_briefAI world brief: daily (prior UTC day, all plans) or weekly/monthly by plan.free
query_developmentsWhat actually CHANGED about the events in an area, not which articles are new.3 tok
get_event_threadOne event end to end: state plus every change in order — the "new event or update" distinction a feed cannot make.free
search_entitiesFind a named place (airport, base, plant, port, dam, strait…) in any language or by IATA/ICAO code.1 tok
get_entityWhat has happened at one place: the registry record plus its most recent linked events, each with HOW it was linked.1 tok
get_related_eventsThe relations recorded for one event: others at the same registry facility, naming the same place, or stored as the same campaign, each saying what is shared; plus reports merged into it.1 tok

Plan

Whether a satellite can resolve it, which one, and when it next passes.

ToolWhat it doesCost
search_imagerySearch the imagery catalog over an area and window.2 tok
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.4 tok
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.1 tok
survey_observable_eventsWhich events a sensor can actually RESOLVE, over the FULL set.1 tok
predict_satellite_passesWHEN a place can next be imaged and by WHAT: 13 free-systematic and commercial-taskable families.2 tok
lookup_elevationTerrain 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_terrainCompute FROM the terrain.free

Analyze

Turn reporting into a cited assessment you can audit afterwards.

ToolWhat it doesCost
assess_signalAI remote-sensing deep-dive for one signal: what to observe, sensors, a collection window.5/15 tok
ask_analystAsk the Delta Analyst an OSINT/GEOINT question; returns a structured brief.5–123 tok
get_analyst_jobStatus and result of an ask_analyst run.free
measure_index_seriesMeasure a spectral index over an area scene by scene through the Sentinel-2 archive.0.5 tok
detect_shipsCount vessel-like targets in ONE Sentinel-1 SAR scene by CFAR detection — radar sees through cloud and at night.5 tok

Watch

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.

ToolWhat it doesCost
create_standing_orderPut an area under CONTINUOUS watch (the app’s "Watch this area"): checked weekly, notifying only when new events cross the bar.free
list_standing_ordersThe 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
list_monitored_areasPlaces under continuous satellite measurement: metric, latest value, change, anomaly flag, coverage.free
get_monitored_areaOne monitored area with its full measurement history.free
create_monitored_areaPut a place under continuous satellite measurement — every new Sentinel-1/2 or VIIRS acquisition (or FIRMS fire detection) is measured.free
list_watchesThe Watchlist as one list, each entry with a state bucket.free
get_watchOne watch end to end: target, state, latest change, measurements with recent series, standing-order questions, and for an event watch its stage, developments and thread, plus this account's notes.free
create_watchAdd a target to the Watchlist.free
update_watchPause, resume or close a watch.free
delete_watchDelete a watch and its underlying resources — bound monitored areas with their history, and standing orders.free
add_noteAdd a note to a watch, start a thread, or reply.free
delete_noteDelete one note from a watch.free

Workspace

The map assets you own — saved layer sets and your own uploaded data.

ToolWhat it doesCost
list_layer_setsThe layer sets saved on this account.free
get_layer_setOne saved layer set by id.free
list_uploaded_layersThe data this account uploaded to the map, plus the formats the uploader accepts.free

Account

Pre-flight your token balance before a metered call.

ToolWhat it doesCost
get_usageThe calling key's remaining token balance and plan capabilities.free

Pricing and metering

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.

Authentication

Two credentials are accepted on the hosted endpoint:

  • OAuth 2.1 with PKCE and Dynamic Client Registration — for interactive clients
  • Bearer API key (Authorization: Bearer ond_...) — for servers, CI, and this stdio package

Keys are shown once at creation, hashed at rest, and revocable at any time from /account/api.
