WHAT IT DOES

What add does on Agent Reliability Lab

AI agents call add as a supporting operation in Agent Reliability Lab workflows.

RISK

Why add is rated Low

Adding two integers is a stateless mathematical computation. It does not read from or write to any system, execute code, delete data, or involve finances. It is a utility/helper function that fits none of the primary risk categories.

From the tool's definition 'Add two integers' — this tool performs a pure arithmetic operation with no side effects, data access, execution, or financial implications.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs add safely

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

add Rate-limited

add gets a rate cap, and everything else on the server is denied unless you say otherwise.

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

FAQ

Questions about add

What does the add tool do? +

Add two integers. It is categorised as a Other tool in the Agent Reliability Lab MCP Server, which means it performs auxiliary operations.

How do I enforce a policy on add? +

Register the Agent Reliability Lab 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 Agent Reliability Lab. Nothing to install.

What risk level is add? +

add is a Other tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit add? +

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.

How do I block add completely? +

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.

What MCP server provides add? +

add is provided by the Agent Reliability Lab MCP server (Andrem19/agent-reliability-lab). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
