A side-by-side look at the Spaceflight News and Orbit Sentinel MCP MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Spaceflight News for aerospace & astrodynamics work as a local process; choose Orbit Sentinel MCP for aerospace & astrodynamics over a hosted endpoint. You can also run both side by side in one mcpServers block.

search_articlesFull-text search spaceflight news articles aggregated from dozens of sources (Spaceflight Now, NASASpaceflight, NASA, SpaceX, Blue Origin, ESA, and more). Filter by source, publish date, and featured status. Newest first. Keyless.get_articleGet a single spaceflight news article by its numeric id, with the full untruncated summary plus any associated launches and events. Keyless.latest_reportsLatest long-form spaceflight mission reports (longer than standard news articles), newest first. Keyless.list_sourcesList every news source the Spaceflight News API aggregates, plus the API version. Use the names to filter search_articles by news_site. Keyless.get_bond_portfolioGet FCC surety bond portfolio for satellite operators. Two distinct figures per operator: the POSTED bond, which is an amount an FCC document states and is absent for most authorizations, and the COMPUTED 47 CFR 25.165 liability, which is Orbit Sentinel's own arithmetic and is not a bond anyone has posted. Never report a computed figure as an operator's actual bond, and read 'not documented' as unknown rather than zero. Also returns summary statistics and FAA financial responsibility data. Use for questions about satellite operator financial obligations, bond compliance, or TPL coverage.get_entity_dossierGet a cross-source dossier for an entity (by UUID): regulatory filings, SEC financial signals, sanctions/export-control screening hits, and asset footprint (satellites, ground stations, federal awards, surety bonds) — counts plus recent samples in one call. The most complete single view of an operator. Set include_family=true to roll the totals up across the entity's corporate family.get_entity_profileGet a detailed entity profile including filing history by agency, related entities (co-filers), linked satellites, and cross-references.get_filing_detailGet full details of a specific regulatory filing, by UUID or agency file number, including spectrum data, orbital parameters, ground stations, signals, related filings, attachments, and (for policy filings) executive summary, overall stance, and structured arguments.get_filing_distributionGet filing count distribution by filing type. Filter by agency and date range. Use for questions about what types of filings are most common.get_filing_trendsGet filing volume trends over time periods with optional top movers (entities with biggest changes). Use for questions about growth, trends, emerging players, or year-over-year comparisons.get_launch_historyGet launch history for a space entity. Returns launches from the FAA/GCAT database including vehicle type, launch site, outcome, and date. Requires entity_id.get_system_statusGet system health status including database connectivity, pipeline queue depth, and per-source crawl health.get_top_filersGet the top filing entities ranked by number of filings. Filter by agency and date range. Use for questions about who files the most, biggest players, or filing rankings.milestone_adherenceFCC deployment milestone adherence (47 CFR 25.164): which authorized satellite systems met their deployment milestones. Grading is deliberately asymmetric — an adverse grade must be earned, a favourable grade must be labelled. 'missed' and 'met_late' appear only where a human verified a cited FCC document; otherwise the row reads 'verification_required', which asserts nothing about the operator and must not be reported as a miss. Favourable grades are never withheld, so read verification_status: 'arithmetic_corroborated' means the deployment counts independently agree — a computation, not a person, did the corroborating — and 'uncorroborated' means the arithmetic is SILENT, not that it disagrees; no favourable grade is currently contradicted by the data. computed_grade always carries the raw arithmetic even where classification withholds it. Filter by call_sign, classification, is_ngso; set summary=true for aggregate counts, which include withheld_adverse and uncorroborated_favourable.researchPrimary research tool — searches filings, entities, and semantic index in parallel. Use this FIRST for any question. Pass the agency parameter for agency-specific questions (e.g., agency="FCC" for FCC questions).search_entitiesSearch regulatory entities (companies, operators, manufacturers, governments) by name, type, or country. Supports fuzzy name matching.Paste either block (or both) into your client config, e.g. claude_desktop_config.json or ~/.cursor/mcp.json. We only show a config when the install command is confirmed.
