Space economy data, wherever your team thinks.
Off Earth Data is now available as an MCP server. Query 5,700+ entities across 27 sectors and the spaceport registry from inside Claude, Copilot, and Cursor. Paid plans add activity, SEPI scores, and rankings.

}Authenticate with an API key from your account page. Every account can connect — your plan sets the data boundary and the monthly allowance. Horizon (free) keys return directory-tier fields; every paid plan returns full data.
Claude Desktop and claude.ai can skip the key entirely — add Off Earth Data as a custom connector and sign in. Step-by-step in the setup guide (sign-in required).
Why MCP access
Research workflows increasingly run inside AI assistants. MCP puts the same company data, activity, and SEPI scores from the dashboard into those conversations.
Frequently asked questions
MCP (Model Context Protocol) is an open standard that lets AI assistants connect to daily-updated external data sources. For space sector analysts, this means you can query OED data directly from Claude or Cursor without leaving your workflow. No more tab switching or copy-pasting between tools.
OED works with Claude Desktop, claude.ai, Claude Code, Cursor, and other MCP clients that connect over Streamable HTTP. ChatGPT is not verified yet.
Every MCP tool call is a request against your API key, metered the same way as direct REST API calls. Your plan sets the monthly allowance and the per-minute rate limit: Horizon 100 units/mo at 5/min, Aperture 1,000 units/mo at 30/min, Meridian 10,000 units/mo at 60/min, Constellation 50,000 units/mo at 120/min, Observatory unmetered at 300/min. Queries are counted per tool invocation, not per conversation turn.
Yes. Observatory (enterprise) customers can connect OED to internal AI systems via the same MCP protocol. We provide dedicated endpoints and can work with your security team on custom authentication flows.
MCP serves the same company directory, activity feed, SEPI scores and rankings, and spaceport data that you see in the OED dashboard, under the same field-level access as the site: Horizon (free) keys return the directory boundary (identity, classification, and the SEPI tier badge), while every paid plan returns numeric scores, exact values, and full history. The difference is how you access it: through natural language queries in your AI assistant instead of clicking through a UI.
Create one from the API Keys section of your account page — any active workspace with MCP Lite access can mint a key. The full key is shown once at creation; copy it into your client config as the X-API-Key header. Horizon keys return directory-boundary data; every paid plan returns full data at its monthly allowance. You can revoke or rotate keys from the same page at any time.
