AI agents invoke affinity_select_tool to trigger actions in MCP Affinity Designer Server. 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.
This tool triggers an external operation in Affinity Designer by activating/switching to a specific tool in the application. It interacts with an external application's UI state rather than simply reading data or writing content. While relatively low-risk on its own, it constitutes an external application action that could be a precursor to further automated operations, placing it in the Execute category.

Documented attack patterns abuse exactly the kind of access affinity_select_tool gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Affinity Designer Server, and nothing reaches the server without passing your rules. This is the rule we recommend for affinity_select_tool:
{
"version": "1",
"default": "deny",
"tools": {
"affinity_select_tool": {
"limits": [
{
"counter": "affinity_select_tool_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}affinity_select_tool 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.

Select a specific tool in Affinity Designer / Affinity Designerで特定のツールを選択. It is categorised as a Execute tool in the MCP Affinity Designer Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the MCP Affinity Designer Server MCP server in PolicyLayer and add a rule for affinity_select_tool: 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 MCP Affinity Designer Server. Nothing to install.
affinity_select_tool 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 affinity_select_tool 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_select_tool. 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_select_tool is provided by the MCP Affinity Designer Server MCP server (szgk/mcp-affinity-designer). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP Affinity Designer Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
