Offnadir Delta MCP

What Off-Nadir-Lab/offnadir-delta-mcp MCP server does

Off-Nadir-Lab/offnadir-delta-mcp MCP server connects an AI agent to the Off-Nadir Delta intelligence workflow. It starts with source-linked, geolocated signals covering geopolitical, security, disaster, and infrastructure events. Agents can inspect event trends, geographic concentrations, related events, entity histories, and the full sequence of changes for an individual event.

The service also supports evidence planning. An agent can search Sentinel-1, Sentinel-2, and NISAR imagery, predict when a place may be imaged, assess whether an event is observable, and generate a collection recommendation. Terrain analysis uses the Copernicus DEM GLO-30. Other tools measure Sentinel-2 spectral-index time series and detect vessel-like targets in a Sentinel-1 SAR scene.

For analysis and auditability, the server provides a Daily World Brief, an OSINT/GEOINT analyst, claim records with evidence classifications, and tools for refining an event location or testing competing hypotheses.

How it works

The hosted MCP endpoint is available at https://offnadir-delta.com/api/v1/mcp. MCP clients connect over HTTP and authenticate through OAuth 2.1; Dynamic Client Registration is supported. This is the recommended route when the client supports remote OAuth connections.

A local stdio option is also available through the offnadir-delta-mcp npm package. The package forwards tool calls to the hosted service using the caller's API key. Tool discovery is available locally from a generated catalog, so clients can inspect the tool list without credentials, but calls require the configured key.

The service uses token metering for many operations. The README states that 23 of 41 tools are free, while other calls have costs listed in tokens. Creating and listing standing orders is free, and continuous-watch charges apply when a check fires or a new acquisition is measured.

Setup and configuration

For a remote connection, configure the endpoint URL in a compatible MCP client and approve the OAuth request. The README gives Claude and ChatGPT connector instructions, and identifies Cursor and VS Code one-click installation options on the documentation site.

For local stdio, run:

{
  "command": "npx",
  "args": ["-y", "offnadir-delta-mcp"],
  "env": {
    "OFFNADIR_DELTA_API_KEY": "ond_..."
  }
}

The API key is obtained from the Off-Nadir Delta account API page. Docker is also documented with the same OFFNADIR_DELTA_API_KEY environment variable.

Tools and capabilities

The Off-Nadir-Lab/offnadir-delta-mcp MCP server groups its tools into four practical areas:

• Discover: Query signals, statistics, hotspots, developments, entities, related events, event threads, and the Daily World Brief.
• Plan: Search imagery, plan event imagery, rank imaging priorities, survey observable events, predict satellite passes, test hypotheses, and analyze elevation or terrain.
• Analyze: Assess signals, ask the Delta Analyst questions, retrieve analyst jobs, inspect claims, refine locations, measure index series, and detect ships.
• Watch: Create, list, pause, resume, and delete standing orders; create monitored areas and inspect their latest values or measurement histories.

Tool costs vary. Analyst questions, remote-sensing assessments, location refinement, imagery planning, and ship detection are metered according to the published tool reference.

Limitations and notes

Results are intended for current OSINT/GEOINT workflows rather than a static training snapshot, but the material does not describe the underlying source coverage, update latency, or guaranteed availability. Satellite tools recommend or analyze available observations; they do not claim that every event can be resolved or that imagery collection will occur automatically.

The local package is a forwarding client for the hosted service, not a separately described data backend. A client that cannot perform remote OAuth can use the API-key-based stdio configuration instead. Token requirements and tool pricing should be checked before using metered operations at scale.
