Inspect the frontmost Affinity window — buttons, text fields, dialogs, etc.
AI agents call affinity_get_ui to retrieve information from Affinity MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about the current state of the Affinity application's user interface. It performs inspection only—examining buttons, text fields, and dialogs—without creating, modifying, deleting, or executing any actions. This is a pure read operation with minimal blast radius even if misused by an AI agent, as it cannot cause damage or unwanted changes to documents or system state.
From the tool's definition Tool name 'affinity_get_ui' and description 'Inspect the frontmost Affinity window — buttons, text fields, dialogs, etc.' indicate querying/retrieving UI state with no modifications or side effects.
Attacks that exploit this kind of access
Inspect the frontmost Affinity window — buttons, text fields, dialogs, etc. It is categorised as a Read tool in the Affinity MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Affinity MCP Server MCP server in PolicyLayer and add a rule for affinity_get_ui: 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 Affinity MCP Server. Nothing to install.
affinity_get_ui 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 affinity_get_ui 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 affinity_get_ui. 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.
affinity_get_ui is provided by the Affinity MCP Server MCP server (sekharmalla/affinity-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
