What package-resolve does on Search
AI agents invoke package-resolve 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 package-resolve is rated High
Resolving dependencies involves executing an external tool (Swift Package Manager) that fetches packages from the network and writes/updates lock files. This goes beyond a simple read — it triggers external operations and modifies state, placing it in the Execute category. Misuse could pull in unintended dependency versions or modify project state.
From the tool's definition 'Resolves Swift package dependencies' — dependency resolution runs external package manager commands (e.g., swift package resolve) which performs network operations and modifies the package resolution file (Package.resolved).
Attacks that exploit this kind of access
The rule that runs package-resolve 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 package-resolve, this is the rule to start with:
package-resolve 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 package-resolve call is checked against it from then on.
Questions about package-resolve
Resolves Swift package dependencies and returns structured resolution results. 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 package-resolve: 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.
package-resolve 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 package-resolve 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 package-resolve. 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.
package-resolve 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.
