README Documentation
Space Frontiers MCP Server
A retrieval layer for AI agents over peer-reviewed papers, books, patents, Wikipedia, Reddit, Telegram, and YouTube. Returns full text and canonical source URIs for citation.
Hosted at https://mcp.spacefrontiers.org/ (Streamable HTTP transport, OAuth 2.1 with PKCE or Bearer API key).
Tools
All four tools are read-only, idempotent, and prefixed spacefrontiers_ to avoid collisions in multi-server agent setups.
| Tool | When to use |
|---|---|
spacefrontiers_search_documents | Peer-reviewed papers, books, patents, Wikipedia. Use for citations and prior art. |
spacefrontiers_search_social | Reddit, Telegram channels, YouTube transcripts. Use for news and community discussion. |
spacefrontiers_fetch_document | Full text + references for one canonical URI (DOI, arXiv, PMID, ISBN). |
spacefrontiers_search_in_document | Passages within one document by query. Use for documents over ~20K tokens. |
Every search hit includes source_uri, score, snippet, authors, issued_date, and content_size_tokens for typed parsing and citation.
Install
The hosted server has its own /mcp install page with one-click links for Cursor, VS Code, and Smithery.
