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

How to run each
API Gateway As a local MCP server: Docker image
claude mcp add --transport stdio mcp-api-gateway -- docker run -i --rm mcp/api-gatewayM3 Memory As a local MCP server: PyPI package
claude mcp add --transport stdio m3-memory -- uvx m3-memoryCommands built only from what the marketplaces declare; the full set for every client is on each card.
Tools each declares
The marketplaces of M3 Memory publish no list of tools, so we do not compare tools.
