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.

What each says it does

Hoverfly

In its own words, on Docker MCP Catalog:

A Model Context Protocol (MCP) server that exposes Hoverfly as a programmable tool for AI assistants like Cursor, Claude, GitHub Copilot, and others supporting MCP. It enables dynamic mocking of third-party APIs to unblock development, automate testing, and simulate unavailable services during integration.

Postman MCP Server

In its own words, on Official MCP Registry:

Give your AI agents trusted access to the full Postman platform.

Tool names as each marketplace publishes them. More tools is not better in itself: compare what each needs for the job.

Settings each asks for

The marketplaces of Hoverfly publish no settings it asks for, so we do not compare settings.
