WHAT IT DOES

What projects_create_message does on ServiceTitan MCP Server

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

RISK

Why projects_create_message is rated Medium

The tool creates (writes) a message, which is a reversible operation—messages can typically be edited or deleted. This fits the Write category rather than Execute, as it appears to persist data rather than trigger external operations. Severity is medium because misuse could result in unwanted messages being created within projects, but the impact is bounded and reversible.

From the tool's definition Tool name 'projects_create_message' indicates creation of a message resource within a project context. The 'create' verb and messaging capability suggests reversible data modification. Description is empty, reducing confidence.

RECOMMENDED RULE

The rule that runs projects_create_message safely

projects_create_message Rate-limited

projects_create_message 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.
