Exa MCP Server vs Orbit Sentinel MCP
A side-by-side look at the Exa MCP Server 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 Exa MCP Server for search & data extraction 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.

Tools & capabilities
Exa MCP Server tools 2
web_search_exaSearch the web for any topic and get clean, ready-to-use content. Best for: Finding current information, news, facts, people, companies, or answering questions about any topic. Returns: Clean text content from top search results. Query tips: describe the ideal page, not keywords. "blog post comparing React and Vue performance" not "React vs Vue". Use category:people / category:company to search through Linkedin profiles / companies respectively. If highlights are insufficient, follow up with web_fetch_exa on the best URLs.web_fetch_exaRead a webpage's full content as clean markdown. Use after web_search_exa when highlights are insufficient or to read any URL. Best for: Extracting full content from known URLs. Batch multiple URLs in one call. Returns: Clean text content and metadata from the page(s).
Orbit Sentinel MCP tools 22
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.

Frequently asked questions
Exa MCP Server is categorized under Search & Data Extraction and uses a local stdio subprocess. Orbit Sentinel MCP belongs to Aerospace & Astrodynamics and uses a remote HTTP/SSE transport. Pick Exa MCP Server for search & data extraction work and Orbit Sentinel MCP for aerospace & astrodynamics.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Exa MCP Server is listed as free. Auth: no auth required. Orbit Sentinel MCP has no declared pricing — check the project's own site. Auth: api key required. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add exa-labs-exa-mcp-server and viventine-space-orbit-sentinel-mcp as separate keys in the same mcpServers object, and your assistant will call tools from either one.
