AI agents call get-rc-version to retrieve information from React Native Upgrader MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a pure data retrieval operation—it fetches and lists available React Native RC versions from GitHub. There are no side effects, no code execution, no data modification, and no destructive operations. It is informational only and safe for an AI agent to use.
From the tool's definition Tool description states it 'Gets the latest release candidate versions of React Native from GitHub releases' and 'returns a list of available release candidate versions'.
Documented attack patterns abuse exactly the kind of access get-rc-version gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and React Native Upgrader MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for get-rc-version:
{
"version": "1",
"default": "deny",
"tools": {
"get-rc-version": {}
}
}get-rc-version is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Gets the latest release candidate versions of React Native from GitHub releases. OVERVIEW: This tool returns a list of available release candidate versions that you can use for upgrading. VERSION FORMAT: • The version numbers follow semantic versioning (e.g. 0.72.0-rc.0) • Include the release candidate tag RELEASE CANDIDATE INFO: • Each version in the returned list represents a pre-release that has undergone testing • May still contain bugs as they are not production-ready USAGE: • This tool is commonly used before planning an upgrade to evaluate new features and changes in upcoming releases • The versions can be used with the get-react-native-diff tool to preview changes before upgrading • Please select one version from the returned list to use for the upgrade process. It is categorised as a Read tool in the React Native Upgrader MCP MCP Server, which means it retrieves data without modifying state.
Register the React Native Upgrader MCP server in PolicyLayer and add a rule for get-rc-version: 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 React Native Upgrader MCP. Nothing to install.
get-rc-version 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-rc-version 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-rc-version. 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-rc-version is provided by the React Native Upgrader MCP server (patrickkabwe/react-native-upgrader-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from React Native Upgrader MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
