Subtract two numbers
AI agents call subtract to retrieve information from AI Research Assistant MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Subtraction is a read-only computation that takes numeric inputs and returns a result. It does not create, modify, delete, or execute any external operations. Despite the broader context of the AI Research Assistant server handling documents and databases, this specific tool is a simple arithmetic function with no capacity to affect data or trigger actions.
From the tool's definition Tool name is 'subtract' with description 'Subtract two numbers'. This performs a pure mathematical operation with no side effects on external systems, data stores, or application state.
Attacks that exploit this kind of access
Subtract two numbers. It is categorised as a Read tool in the AI Research Assistant MCP Server MCP Server, which means it retrieves data without modifying state.
Register the AI Research Assistant MCP Server MCP server in PolicyLayer and add a rule for subtract: 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 AI Research Assistant MCP Server. Nothing to install.
subtract 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 subtract 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 subtract. 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.
subtract is provided by the AI Research Assistant MCP Server MCP server (sagarkpoojary/sagar-mcp-project). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
