Get monitor brightness level
Part of the Ddc Ci Control Bridge MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call get_brightness to retrieve information from Ddc Ci Control Bridge 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 get_brightness 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.

Get monitor brightness level. It is categorised as a Read tool in the Ddc Ci Control Bridge MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for get_brightness. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Ddc Ci Control Bridge MCP server.
get_brightness 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_brightness 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.
Set action: deny in the Intercept policy for get_brightness. 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_brightness is provided by the Ddc Ci Control Bridge MCP server (ddc-ci-control-bridge). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Open source. One binary. Zero dependencies.
