WHAT IT DOES

What search_fonts does on Mcp

AI agents call search_fonts to retrieve information from Mcp 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
`sort`	string	—	Optional. The sort order for the returned font families. Defaults to POPULARITY_DESCENDING if unspecified.
`platform`	string	Yes	Required. The platform in which the font family is going to be used.
`languages`	array	—	Optional. Language tags in BCP47 format to filter fonts that support specific scripts (e.g., "en_Latn", "zh_Hans").
`categories`	array	—	Optional. One or more categories to filter font families

Parameters from the server's own tool schema.

RISK

Why search_fonts is rated Low

Even though search_fonts 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.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs search_fonts safely

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

search_fonts Allowed

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

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "search_fonts": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

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