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.

claude mcp add --env "OSINTSX_API_KEY=<YOUR_OSINTSX_API_KEY>" --transport stdio osintsx-mcp -- npx -y osintsx-mcpRequires: OSINTSX_API_KEY (secret)
Commands built only from what the marketplaces declare; the full set for every client is on each card.
Tools each declares
Neither one's marketplaces publish a list of tools, so there is nothing to compare.
Settings each asks for
Only OpenOSINT asks for
ABUSEIPDB_API_KEY (secret)ANTHROPIC_API_KEY (secret)HIBP_API_KEY (secret)IP2LOCATION_API_KEY (secret)IPINFO_TOKEN (secret)
Only OSINT.SX asks for
OSINTSX_API_KEY (secret)
Settings as each marketplace publishes them. Asking for fewer is not better in itself.
