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.

Tools each declares
The marketplaces of PostgreSQL MCP Server publish no list of tools, so we do not compare tools.
Settings each asks for
Only CockroachDB asks for
CRDB_DATABASECRDB_HOSTCRDB_PORTCRDB_PWD (secret)CRDB_SSL_CA_PATHCRDB_SSL_CERTFILECRDB_SSL_KEYFILECRDB_SSL_MODECRDB_USERNAME
