Get the latest version of a Swift package from GitHub.
AI agents call get_swift_package to retrieve information from Versionator without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query against a package registry (GitHub) to fetch version information and package metadata. It has no side effects, does not modify data, execute code, or commit financial transactions. The action is a simple retrieval operation consistent with the 'Read' category.
From the tool's definition Tool name 'get_swift_package' and description 'Get the latest version of a Swift package from GitHub' indicate a query operation that retrieves metadata without modification.
Attacks that exploit this kind of access
Get the latest version of a Swift package from GitHub. It is categorised as a Read tool in the Versionator MCP Server, which means it retrieves data without modifying state.
Register the Versionator MCP server in PolicyLayer and add a rule for get_swift_package: 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 Versionator. Nothing to install.
get_swift_package 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 get_swift_package 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 get_swift_package. 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.
get_swift_package is provided by the Versionator MCP server (trianglegrrl/versionator-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
