Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.

What each says it does

VeyraX

How to run each

VeyraX As a local MCP server: Docker image

Claude Code

claude mcp add --env "VEYRAX_API_KEY=<YOUR_VEYRAX_API_KEY>" --transport stdio veyrax -- docker run -i --rm -e VEYRAX_API_KEY mcp/veyrax

Requires: VEYRAX_API_KEY (secret)

io.github.cyanheads/astronomy-mcp-server As a remote MCP server

Claude Code

claude mcp add --transport http astronomy-mcp-server https://astronomy.caseyjhand.com/mcp

Commands built only from what the marketplaces declare; the full set for every client is on each card.

Only io.github.cyanheads/astronomy-mcp-server has a remote endpoint we check. How we check endpoints

Tools each declares

Only VeyraX has

get_flow
get_tools
tool_call

Only io.github.cyanheads/astronomy-mcp-server has

astronomy_find_events
astronomy_get_ephemeris
astronomy_get_moon_phase
astronomy_get_rise_set
astronomy_get_satellite_passes
astronomy_get_sky_position
astronomy_list_visible

Both have

None

Tool names as the marketplaces declare them and as Ext Ops observed them on the endpoints (io.github.cyanheads/astronomy-mcp-server as of 2026-10-17). More tools is not better in itself: compare what each needs for the job.

Settings each asks for

Only VeyraX asks for

VEYRAX_API_KEY (secret)

Only io.github.cyanheads/astronomy-mcp-server asks for

ASTRONOMY_DEFAULT_TIMEZONE
ASTRONOMY_ENABLE_HORIZONS
ASTRONOMY_ENABLE_SATELLITES
MCP_AUTH_MODE
MCP_HTTP_ENDPOINT_PATH
MCP_HTTP_HOST
MCP_HTTP_PORT
MCP_LOG_LEVEL
MCP_TRANSPORT_TYPE

Settings as each marketplace publishes them. Asking for fewer is not better in itself.
