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.

What each says it does
credentials
Handles API keys, tokens, and facility credentials (kerberos tickets, globus and scheduler tokens, ssh agents, netrc) before a tool needs one, after an auth error, when a new secret is supplied, or when one may have leaked. Not for provider target configuration; use clio-coder auth and target settings.
Postman MCP Server
Give your AI agents trusted access to the full Postman platform.
How to run each

No data for an automatic command: what its marketplaces declare does not say unambiguously how to connect it.
