HVAC and plumbing shops: what an AI agent can and can't do with your software

Who this is for: owners and office managers at HVAC, plumbing and similar service shops who want to know which parts of their software stack an AI agent can work with today. The first agent covered is Muse, Meta's personal agent with a small-business mode. Other agents can be added to the same tables later.

Every claim below links its source and carries the date we checked it.

How to read the status labels

LabelMeaning
Confirmed by vendorThe software company or Meta says it in its own docs, help center, blog or press release.
Confirmed by the [agency]A government agency says it on its own site, and the label names that agency (for example "Confirmed by the FCC" or "Confirmed by the FTC").
ReportedA press outlet or independent site says it, and we haven't found it in the vendor's own material.
ConflictingSources disagree. We show both.
UnverifiedWe couldn't confirm it. Treat it as an open question.

We haven't run these tasks ourselves. "The vendor says" doesn't mean "we tested it." See how we check.

What "custom connector" means here: Muse lets you add connectors that Meta hasn't built, and Meta says it doesn't review them. (Confirmed by vendor 4) You (or someone you hire) are responsible for what a custom connector can see and do. Your field-service vendor's own rules still apply. For example, Jobber blocks API access for an unpublished app that connects to more than 5 paying Jobber accounts. (Confirmed by vendor 6) Whether Jobber's official connector can be added to Muse as a custom connector hasn't been shown publicly. (Unverified)
