What add does on Search
AI agents invoke add to trigger actions in Search. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why add is rated High
The description is truncated to just 'Runs', which implies command execution. Given the sibling tools (add-package, ansible-playbook, bazel) and the server's nature, this tool likely executes an external operation. Without more detail, Execute is the most appropriate category, but confidence is low due to the uninformative description.
From the tool's definition Tool name is 'add' with description only saying 'Runs' (truncated/uninformative). Server context involves structured code search operations (ripgrep + fd), sibling tools include package management, ansible, bazel — suggesting 'add' likely runs a command to…
Attacks that exploit this kind of access
The rule that runs add safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Search, 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 stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Search, apply this rule, and every add call is checked against it from then on.
Questions about add
Runs. It is categorised as a Execute tool in the Search MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Search 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 Search. Nothing to install.
add is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
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 Search MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
