Add two numbers together.
AI agents call add to retrieve information from MCP Multi-Tool 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 mathematical addition operation. It only computes and returns a result without reading from or writing to any data store, executing commands, or triggering external systems. It is a stateless calculation, closest to 'Read' as it produces output from input with no side effects.
From the tool's definition 'Add two numbers together' — pure arithmetic computation with no side effects, data modification, or external operations.
Attacks that exploit this kind of access
Add two numbers together. It is categorised as a Read tool in the MCP Multi-Tool Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Multi-Tool Server MCP server in PolicyLayer and add a rule for add: 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 MCP Multi-Tool Server. Nothing to install.
add 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 add 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 add. 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.
add is provided by the MCP Multi-Tool Server MCP server (xiaoyuchenhot/mcp-example). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
