Find a template inside an image (TM_CCOEFF_NORMED). Returns matches above threshold.
AI agents call template_match to retrieve information from farshid-mcp-imageProcessing without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Template matching is a passive computer vision operation that analyzes image content and returns coordinate/confidence data about matching regions. It does not create, modify, delete, or execute code/commands. The lack of any output arguments or state-changing operations confirms this is a Read category tool.
From the tool's definition Tool description states it 'Find[s] a template inside an image' and 'Returns matches above threshold'. These are query/search operations with no side effects—the tool retrieves or identifies data within an image without modifying, deleting, or executing…
Attacks that exploit this kind of access
Find a template inside an image (TM_CCOEFF_NORMED). Returns matches above threshold. It is categorised as a Read tool in the farshid-mcp-imageProcessing MCP Server, which means it retrieves data without modifying state.
Register the farshid-mcp-imageProcessing MCP server in PolicyLayer and add a rule for template_match: 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 farshid-mcp-imageProcessing. Nothing to install.
template_match 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 template_match 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 template_match. 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.
template_match is provided by the farshid-mcp-imageProcessing MCP server (pirahansiah/farshid-mcp-imageprocessing). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
