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
Xero
Read and write invoices, contacts, reports, and payroll.
io.github.ar-agents/mcp
Argentine business automation: Mercado Pago, AFIP/ARCA, WhatsApp, banking, shipping (7 packages).
How to run each
Xero
No data for an automatic command: what its marketplaces declare does not say unambiguously how to connect it.
io.github.ar-agents/mcp As a local MCP server: npm package
claude mcp add --env "AFIP_CERT_PEM=<YOUR_AFIP_CERT_PEM>" --env "AFIP_KEY_PEM=<YOUR_AFIP_KEY_PEM>" --env "MP_ACCESS_TOKEN=<YOUR_MP_ACCESS_TOKEN>" --env "WHATSAPP_ACCESS_TOKEN=<YOUR_WHATSAPP_ACCESS_TOKEN>" --transport stdio io-github-ar-agents-mcp -- npx -y @ar-agents/mcpRequires: AFIP_CERT_PEM (secret), AFIP_KEY_PEM (secret), MP_ACCESS_TOKEN (secret), WHATSAPP_ACCESS_TOKEN (secret)
Commands built only from what the marketplaces declare; the full set for every client is on each card.
Tools each declares
Neither one's marketplaces publish a list of tools, so there is nothing to compare.
Settings each asks for
Only Xero asks for
XERO_CLIENT_IDXERO_CLIENT_SECRET (secret)
Only io.github.ar-agents/mcp asks for
AFIP_CERT_PEM (secret)AFIP_CUITAFIP_KEY_PEM (secret)MP_ACCESS_TOKEN (secret)WHATSAPP_ACCESS_TOKEN (secret)WHATSAPP_PHONE_NUMBER_ID
Settings as each marketplace publishes them. Asking for fewer is not better in itself.
