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
nitrograph
Nitrograph is a service-discovery network for agents. It helps probabilistic agents transact with deterministic headless payment endpoints. This plugin lets Claude search a curated registry of agent-usable APIs (x402, MPP, and standard HTTP) ranked by trust, reliability, and price, then fetch the exact endpoints, OpenAPI spec, gotchas, and proven multi-step patterns needed to call them. No API key required: free tier with x402 USDC pay-to-continue on Base when the quota is exhausted. Adds four MCP tools (nitrograph_discover, nitrograph_service_detail, nitrograph_report_outcome, nitrograph_report_pattern) and a /discover slash command.
