AI agents call aidefense_get_matrix to retrieve information from Website Search without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though aidefense_get_matrix only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Supports optional filtering by asset or function. This server never requests your program docs or product roadmap and instructs your AI to keep them local—the matrix, framework alignments, and playbooks flow to your AI for local analysis.. It is categorised as a Read tool in the Website Search MCP Server, which means it retrieves data without modifying state.
Register the Website Search MCP server in PolicyLayer and add a rule for aidefense_get_matrix: 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 Website Search. Nothing to install.
aidefense_get_matrix 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 aidefense_get_matrix 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 aidefense_get_matrix. 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.
aidefense_get_matrix is provided by the Website Search MCP server (https://website-mcp.zeltser.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
