WHAT IT DOES

What add does on Dynamic Per-User Tool Generation MCP Server

AI agents use add to create or update resources in Dynamic Per-User Tool Generation MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Dynamic Per-User Tool Generation MCP Server environment.

WHY IT NEEDS A POLICY

Why add needs a policy

While 'add' appears to be a pure computational function, the presence of dynamic tool generation with user-specific permissions and external API integration suggests tools may have broader capabilities than their descriptions indicate.

From the tool's definition The tool name 'add' and description 'Adds two integer numbers together' describe a simple arithmetic operation that modifies state (e.g., accumulates values, updates calculations).

Verdict

add Rate-limited

add stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Dynamic Per-User Tool Generation MCP Server, so you can run agents against it safely.

FAQ

Questions about add

What does the add tool do? +

Adds two integer numbers together. It is categorised as a Write tool in the Dynamic Per-User Tool Generation MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on add? +

Register the Dynamic Per-User Tool Generation MCP 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 Dynamic Per-User Tool Generation MCP Server. Nothing to install.

What risk level is add? +

add is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

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 Dynamic Per-User Tool Generation MCP Server MCP server (shivampansuriya/mcp-server-python). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
