Adds two integers together.
AI agents call calculate_sum to retrieve information from Python FastMCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a simple arithmetic operation on provided inputs and returns a result. It retrieves/computes information without creating, modifying, deleting, or executing external code. It is read-only in nature—a basic calculation utility with no destructive, financial, or execution capabilities.
From the tool's definition Tool name 'calculate_sum' and description 'Adds two integers together' indicate a pure mathematical computation with no side effects, no data modification, and no external operations triggered.
Attacks that exploit this kind of access
Adds two integers together. It is categorised as a Read tool in the Python FastMCP Server MCP Server, which means it retrieves data without modifying state.
Register the Python FastMCP Server MCP server in PolicyLayer and add a rule for calculate_sum: 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 Python FastMCP Server. Nothing to install.
calculate_sum 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_sum 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_sum. 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_sum is provided by the Python FastMCP Server MCP server (rajeshsahu09/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
