WHAT IT DOES

What util_business_days does on Delx MCP Server

AI agents call util_business_days to retrieve information from Delx MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`calendar`	string	—	Holiday calendar
`end_date`	string	Yes	Inclusive end date YYYY-MM-DD
`start_date`	string	Yes	Inclusive start date YYYY-MM-DD

Parameters from the server's own tool schema.

RISK

Why util_business_days is rated Low

Even though util_business_days only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

util_business_days Allowed

util_business_days is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
