faf-mcp Read Risk 2/5

AI agents call faf_check to retrieve information from Faf 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 faf_check 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.

How do I enforce a policy on faf_check? +

Add a rule in your Intercept YAML policy under the tools section for faf_check. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Faf MCP server.

What risk level is faf_check? +

faf_check is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit faf_check? +

Yes. Add a rate_limit block to the faf_check rule in your Intercept 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.

How do I block faf_check completely? +

Set action: deny in the Intercept policy for faf_check. 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.

What MCP server provides faf_check? +
