WHAT IT DOES

What set_resource_availability does on FavCRM

AI agents use set_resource_availability to create or update resources in FavCRM, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your FavCRM environment.

Parameter	Type	Required	Description
`date`	string	—	YYYY-MM-DD for a specific date instead of dayOfWeek
`type`	string	—	Default available
`endTime`	string	Yes	HH:MM (24h)
`dayOfWeek`	string	—	Day of week (0=Sun..6=Sat)
`startTime`	string	Yes	HH:MM (24h)
`resourceId`	string	Yes	Resource ID
`isRecurring`	boolean	—	Default true

Parameters from the server's own tool schema.

RISK

Why set_resource_availability is rated Medium

This tool creates or modifies schedule/availability data for a resource (person, service, or facility) in the CRM. It is reversible — availability windows can be updated or removed later — and does not delete data or trigger external operations. It fits the Write category: creates or modifies data reversibly.

From the tool's definition Tool description states it will 'Add an availability window' — the verb 'Add' denotes creation of a new scheduling record. The parameters reference 'day-of-week', 'recurring', and 'date', all of which are attributes being written to a resource schedule.

RECOMMENDED RULE

The rule that runs set_resource_availability safely

PolicyLayer is an MCP gateway: it sits between your AI agents and FavCRM, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For set_resource_availability, this is the rule to start with:

set_resource_availability Rate-limited

set_resource_availability stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

        }
      ]
    }
  }
}

The button opens the PolicyLayer dashboard: create your workspace, connect FavCRM, apply this rule, and every set_resource_availability call is checked against it from then on.
