Check API availability across Apple platforms and OS versions. Shows minimum deployment targets, deprecations, and platform-specific features. Critical for cross-platform development. Use when: planning app requirements, checking API availability, finding platform alternatives.
AI agents call get_platform_compatibility to retrieve information from Apple Docs MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries Apple's documentation to display compatibility matrices, deprecation notices, and deployment targets. It has no side effects, creates no resources, executes no code, and does not modify or delete data. The blast radius of misuse is minimal: an agent might retrieve irrelevant or misleading compatibility data, but cannot cause harm to systems, data, or operations.
From the tool's definition Tool retrieves API compatibility information across platforms and OS versions without modifying any data. Description emphasizes 'Check', 'Shows', and 'finding' — all read-only operations.
Documented attack patterns abuse exactly the kind of access get_platform_compatibility gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Apple Docs MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for get_platform_compatibility:
{
"version": "1",
"default": "deny",
"tools": {
"get_platform_compatibility": {}
}
}get_platform_compatibility is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Check API availability across Apple platforms and OS versions. Shows minimum deployment targets, deprecations, and platform-specific features. Critical for cross-platform development. Use when: planning app requirements, checking API availability, finding platform alternatives. It is categorised as a Read tool in the Apple Docs MCP MCP Server, which means it retrieves data without modifying state.
Register the Apple Docs MCP server in PolicyLayer and add a rule for get_platform_compatibility: 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 Apple Docs MCP. Nothing to install.
get_platform_compatibility 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_platform_compatibility 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_platform_compatibility. 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_platform_compatibility is provided by the Apple Docs MCP server (kimsungwhee/apple-docs-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Apple Docs MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
