calculate_readability
AI agents call calculate_readability to retrieve information from FastMCP Document Analyzer without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Readability calculation is a computational analysis that examines text properties and returns scores/metrics. This is consistent with the 'Read' category as it retrieves/queries data without side effects. It does not create, modify, delete, execute external code, or transfer funds.
From the tool's definition Tool name 'calculate_readability' indicates it performs a scoring/analysis operation on text. Server description confirms it provides 'readability scoring' as part of its analysis capabilities.
Attacks that exploit this kind of access
calculate_readability. It is categorised as a Read tool in the FastMCP Document Analyzer MCP Server, which means it retrieves data without modifying state.
Register the FastMCP Document Analyzer MCP server in PolicyLayer and add a rule for calculate_readability: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches FastMCP Document Analyzer. Nothing to install.
calculate_readability is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the calculate_readability rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for calculate_readability. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
calculate_readability is provided by the FastMCP Document Analyzer MCP server (tathagat017/document-analyser-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
