Servers that give an agent access to something — a filesystem, an API, a database. Every listing here was approved by a person before it appeared, and links out to the source rather than reproducing it. We deliberately don't publish ready-made config blocks: a working one carries arguments and environment variables, and those are somebody's secrets waiting to happen.
