What the publisher says
From the astrodynamics-mcp repository's README, as published. We do not edit it. Read it on GitHub
astrodynamics-mcp
A Model Context Protocol server that gives any MCP-capable LLM client (Claude Code, Cursor, ChatGPT desktop, custom agents) authoritative astrodynamics tools: TLE/SGP4 propagation, Lambert solving, ground-station access, time-scale and coordinate-frame conversions, porkchop scans, B-plane targeting, satellite metadata, and — with optional extras — full NASA GMAT mission execution ([gmat]), NASA SPICE / NAIF kernel queries ([spice]), and trajectory visualisation ([viz]).
Why
LLMs reason well about astrodynamics concepts but cannot do the numerical work — they cannot propagate orbits, solve Lambert problems, or query SPICE ephemerides. astrodynamics-mcp lets you plug authoritative tools into any MCP-capable client so the LLM calls vetted upstream libraries instead of fabricating numbers. Every result carries explicit units; every tool description tunes against an Inspect AI eval suite that measures whether the LLM picks the right tool and binds the right arguments.
Tools
† Credentialed source. Pass credentials as environment variables for the stdio transport, or in the session-init _meta block for HTTP — see Credentials. A tool called without its credential returns a typed CredentialRequiredError, never a silent failure.
GMAT tools (optional [gmat] extra)
Install the [gmat] extra and have a local NASA GMAT install, and five more tools register for driving real GMAT missions (they stay hidden otherwise):

astrodynamics-mcp: common questions
- Is astrodynamics-mcp server safe?
- Mostly: it is graded B (72/100). Read the astrodynamics-mcp safety report
- How do I install astrodynamics-mcp?
- It runs on your machine. Copy the Claude Code, Cursor, VS Code or Claude Desktop config from the install section.
- Does astrodynamics-mcp need an API key?
- Not as far as the registry entry and our scan can tell: no credentials are declared or required.
- Is astrodynamics-mcp maintained?
- The last commit was 150 days ago (2026-06-07). The latest release is v0.4.0.
- How does astrodynamics-mcp compare with other MCP servers?
- safety score 72/100 (higher than 38% of 48,255 servers); github stars 2 (more than 75% of 28,688 servers); downloads a week 39 (more than 30% of 12,191 servers with a package). Full comparison.
