Each figure is the marketplace's own and is never added up across marketplaces. A marketplace that publishes no figure shows none: no number is not zero.

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
PostgreSQL Performance (read-only)
No data for an automatic command: what its marketplaces declare does not say unambiguously how to connect it.
Requires: MCP_API_KEY (secret), PGPERF_DB_PASSWORD (secret), PGPERF_DB_URL, PGPERF_DB_USER
io.github.mongodb-js/mongodb-mcp-server As a local MCP server: npm package
claude mcp add --env "MDB_MCP_API_CLIENT_ID=<YOUR_MDB_MCP_API_CLIENT_ID>" --env "MDB_MCP_API_CLIENT_SECRET=<YOUR_MDB_MCP_API_CLIENT_SECRET>" --env "MDB_MCP_CONNECTION_STRING=<YOUR_MDB_MCP_CONNECTION_STRING>" --env "MDB_MCP_CONNECTION_STRINGS=<YOUR_MDB_MCP_CONNECTION_STRINGS>" --env "MDB_MCP_VOYAGE_API_KEY=<YOUR_MDB_MCP_VOYAGE_API_KEY>" --transport stdio mongodb-mcp-server -- npx -y mongodb-mcp-serverRequires: MDB_MCP_API_CLIENT_ID (secret), MDB_MCP_API_CLIENT_SECRET (secret), MDB_MCP_CONNECTION_STRING (secret), MDB_MCP_CONNECTION_STRINGS (secret), MDB_MCP_VOYAGE_API_KEY (secret)
