Retrieves the official portrait photograph of a Member of Parliament. Returns the image as a binary resource that can be displayed or saved. Use this when you need to include a visual representation of an MP in reports, presentations, or profiles.
AI agents call get_photo to retrieve information from OpenTK Model Context Protocol Server 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 operation to fetch public biographical/portrait data about Members of Parliament. No data is created, modified, deleted, or overwritten. No code execution, financial transaction, or destructive action is possible.
From the tool's definition Tool retrieves ("Retrieves") and returns ("Returns") an existing portrait photograph with no modification, deletion, or execution capability. The description specifies only data retrieval: "image as a binary resource that can be displayed or saved."
Documented attack patterns abuse exactly the kind of access get_photo gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and OpenTK Model Context Protocol Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_photo:
{
"version": "1",
"default": "deny",
"tools": {
"get_photo": {}
}
}get_photo is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Retrieves the official portrait photograph of a Member of Parliament. Returns the image as a binary resource that can be displayed or saved. Use this when you need to include a visual representation of an MP in reports, presentations, or profiles. It is categorised as a Read tool in the OpenTK Model Context Protocol Server MCP Server, which means it retrieves data without modifying state.
Register the OpenTK Model Context Protocol Server MCP server in PolicyLayer and add a rule for get_photo: 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 OpenTK Model Context Protocol Server. Nothing to install.
get_photo 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_photo 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_photo. 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_photo is provided by the OpenTK Model Context Protocol Server MCP server (r-huijts/opentk-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from OpenTK Model Context Protocol Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
