From the repository
Add the server to Claude Code with claude mcp add --transport http spacefrontiers https://mcp.spacefrontiers.org. For Cursor, VS Code, Cline, or Windsurf, configure the MCP client with the HTTP URL and a Bearer API key. Self-host by cloning the repo, running uv sync, and starting with uv run fastmcp run mcp_server.py after setting the API key.

}Interfaces with the Space Frontiers API, enabling language models to interact with its data sources.
A retrieval layer for AI agents over peer-reviewed papers, books, patents, standards, Wikipedia, Reddit, Telegram, Discord, and YouTube. Returns bounded full text and canonical source URIs for citation.
Hosted athttps://mcp.spacefrontiers.org/(Streamable HTTP transport, OAuth 2.1 with PKCE or Bearer API key).
All four tools are read-only, idempotent, and prefixedspacefrontiers_to avoid collisions in multi-server agent setups.
Search defaults to 10 compact, hybrid-ranked results and is capped at 30. Every hit includes a canonicalsource_uri, one snippet (up to 900 characters), an abstract preview (up to 800 characters), score, authors, date, type, and estimated full-text size. Citation backlinks are opt-in onspacefrontiers_fetch_documentbecause they add another billed search.
The hosted server has its own/mcp install pagewith one-click links for Cursor, VS Code, and Smithery.

- Search: $0.01 base + $0.001 per returned result (the 10-result MCP default costs $0.02).
- Full document fetch: $0.05.
- In-document passage search: $0.015.
- referenced_by_limit > 0on a fetch adds a separately billed search.
