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
Zen As a local MCP server: Docker image
claude mcp add --env "GEMINI_API_KEY=<YOUR_GEMINI_API_KEY>" --env "OPENAI_API_KEY=<YOUR_OPENAI_API_KEY>" --env "OPENROUTER_API_KEY=<YOUR_OPENROUTER_API_KEY>" --env "XAI_API_KEY=<YOUR_XAI_API_KEY>" --transport stdio zen -- docker run -i --rm -e GEMINI_API_KEY -e OPENAI_API_KEY -e OPENROUTER_API_KEY -e XAI_API_KEY mcp/zenRequires: GEMINI_API_KEY (secret), OPENAI_API_KEY (secret), OPENROUTER_API_KEY (secret), XAI_API_KEY (secret)
PinRAG As a local MCP server: PyPI package
claude mcp add --env "OPENROUTER_API_KEY=<YOUR_OPENROUTER_API_KEY>" --transport stdio pinrag -- uvx --refresh pinrag pinragRequires: OPENROUTER_API_KEY (secret)
Commands built only from what the marketplaces declare; the full set for every client is on each card.
Tools each declares
The marketplaces of PinRAG publish no list of tools, so we do not compare tools.
Settings each asks for
Only Zen asks for
GEMINI_API_KEY (secret)XAI_API_KEY (secret)
Only PinRAG asks for
PINRAG_PERSIST_DIR
Settings as each marketplace publishes them. Asking for fewer is not better in itself.
