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.

How to run each
WolframAlpha As a local MCP server: Docker image
claude mcp add --env "WOLFRAM_API_KEY=<YOUR_WOLFRAM_API_KEY>" --transport stdio wolfram-alpha -- docker run -i --rm -e WOLFRAM_API_KEY mcp/wolfram-alphaRequires: WOLFRAM_API_KEY (secret)
io.github.cyanheads/nasa-power-mcp-server As a local MCP server: npm package
claude mcp add --transport stdio nasa-power-mcp-server -- npx -y @cyanheads/nasa-power-mcp-serverCommands built only from what the marketplaces declare; the full set for every client is on each card.
Tools each declares
The marketplaces of io.github.cyanheads/nasa-power-mcp-server publish no list of tools, so we do not compare tools.
Settings each asks for
Only WolframAlpha asks for
WOLFRAM_API_KEY (secret)
Only io.github.cyanheads/nasa-power-mcp-server asks for
CANVAS_ABSOLUTE_CAP_MSCANVAS_DEFAULT_MEMORY_LIMIT_MBCANVAS_MAX_CANVASES_PER_TENANTCANVAS_PROVIDER_TYPECANVAS_TTL_MSMCP_AUTH_MODEMCP_HTTP_ENDPOINT_PATHMCP_HTTP_HOSTMCP_HTTP_PORTMCP_LOG_LEVELMCP_TRANSPORT_TYPENASA_POWER_DATAFRAME_DROP_ENABLED
Settings as each marketplace publishes them. Asking for fewer is not better in itself.
