## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-05.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 72/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 2434 tokens (~173/item across 14 items; 14 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 17/100
  - Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 14 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 15 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (14)

### `next_launches` (~297 tokens)

Next launches

Upcoming orbital launches from the SpaceNexus manifest (the next 50 scheduled), filterable by provider, rocket, launch site and country. Each launch has its NET date and precision, status, the date changes our ledger recorded, and its page URL. realSlips and otherDateMoves count only changes our sync saw when they happened; caughtUpDateMoves counts changes it only caught up with late (made earlier, on a day we do not know), which are never counted as slips.

Input parameters:

- `country` (string): Country of the launch site, by name or code, e.g. "United States", "China", "France" (Kourou), "NZL".
- `include_recent_outcomes` (boolean): Also return launches flown in the last 30 days with their outcome.
- `limit` (integer): How many launches to return (1 to 20).
- `provider` (string): Launch provider: a name or common short name, e.g. "SpaceX", "ULA", "ISRO", "CASC", "Rocket Lab".
- `rocket` (string): Rocket, matched as a substring, e.g. "Falcon 9", "Starship", "Long March".
- `site` (string): Launch site: a spaceport name or slug ("Cape Canaveral" includes Kennedy, "vandenberg", "Starbase", "Andoya") or any pad name.

### `launch_slips` (~209 tokens)

Launch slip ledger

Recent launch date changes as the SpaceNexus slip ledger recorded them (old date, new date, size of the move, kind of move), with totals since recording began and the provider scorecard once the ledger is large enough. Each change carries observation: live (our sync saw it when it happened) or catch-up (our sync only caught up late, so observedAt is when we saw it, not when it changed). Caught-up changes are returned apart in caughtUpChanges and never counted in the summary figures.

Input parameters:

- `limit` (integer): How many recent date changes to return (1 to 25).
- `provider` (string): Only moves by this provider: a name or common short name (ULA, ISRO, CASC).
- `real_moves_only` (boolean): Leave out placeholder moves (a "NET 2026" style date firming or rolling); keep slips, pull-ins and adjustments.
- `rocket` (string): Only moves of this rocket (substring).

### `launch_on_time_record` (~123 tokens)

Launch on-time record

How often launches fly on time: the share of flown launches that lifted off within 1 day and within 7 days of the first firm date on record, with mean and median delay, grouped by provider, vehicle or launch site.

Input parameters:

- `group_by` (string): Group the on-time record by launch provider, vehicle or launch site.
- `limit` (integer): How many groups to return (1 to 25).
- `name` (string): Only groups whose name contains this text, e.g. "SpaceX" or "Falcon 9".

### `recent_funding_rounds` (~149 tokens)

Recent funding rounds

Closed private funding rounds into space companies in the last 90 days, newest first, with amount (null when undisclosed, never estimated), stage, investors, how the round is evidenced and its source link.

Input parameters:

- `limit` (integer): How many rounds to return (1 to 25).
- `min_amount_usd` (number): Only rounds with a disclosed amount at or above this, in US dollars.
- `stage` (string): Round stage, matched as a substring, e.g. "Seed", "Series B".

### `company_lookup` (~128 tokens)

Company lookup

Public profile facts for a space company: what it does, sector, country, headquarters, founding year, public or private, ticker, funding and last round as shown on its profile (for a listed company the funding figure is the private rounds it raised before listing, and fundingBasis says which rule applies), and its Space Score when it is ranked.

Input parameters:

- `limit` (integer): How many matching companies to return (1 to 5).
- `query` (string, required): Company name, profile slug or stock ticker, e.g. "Rocket Lab", "rocket-lab" or "RKLB".

### `space_jobs_count` (~79 tokens)

Space jobs count

How many open roles the SpaceNexus jobs board lists right now (mirrored daily from employers' careers pages), how many employers are hiring, how many roles are new this week or remote, and optionally one employer's open roles.

Input parameters:

Needs a SpaceNexus API key (a free key is enough). The full Launch Ledger record: every launch date change our ledger holds since recording began, one row per launch per UTC observation day, with the observation fields (live or catch-up, the catch-up reason, Launch Library 2's last-updated time), both dates at their precision and its basis, the size and kind of the move, and whether it counts as a slip. Filter by launch, provider, rocket, observation, kind and day; page with offset. The same rows as the free launch-slips dataset.

Input parameters:

- `kind` (string): Only this kind of move: slip, pull-in, adjust, firmed, loosened or placeholder.

- `since` (string): Only changes observed on or after this UTC day (YYYY-MM-DD).

### `promise_ledger_entries` (~209 tokens)

Promise Ledger entries

### `space_score_history` (~124 tokens)

Space Score history

Needs a SpaceNexus API key whose owner has SpaceNexus Research (the Space Score history is a Research product).

## Common questions

### What is the SpaceNexus space data MCP server?

SpaceNexus space data is an MCP server listed in the public MCP registry as us.spacenexus/spacenexus. Read-only space industry data: launches, slips, funding, companies, space weather, Moon race, jobs. This page covers its hosted endpoint (https://spacenexus.us/api/mcp).

### Is the SpaceNexus space data MCP server safe to use?

SpaceNexus space data scores 75 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the SpaceNexus space data MCP server expose?

SpaceNexus space data exposes 14 tools: next_launches, launch_slips, launch_on_time_record, recent_funding_rounds, company_lookup, and 9 more. Their descriptions and schemas cost roughly 2,225 tokens of context every time the server is loaded.

### Does the SpaceNexus space data MCP server require authentication?

No. We connected to SpaceNexus space data without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the SpaceNexus space data MCP server still maintained?

SpaceNexus space data is still listed as active in the MCP registry. We last reached this channel on 5 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
