harmonyos_list_modules

List all modules in a HarmonyOS project with their types

Part of the Mcp Harmonyos MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

AI agents call harmonyos_list_modules to retrieve information from Mcp Harmonyos 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 harmonyos_list_modules 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.

What does the harmonyos_list_modules tool do? +

List all modules in a HarmonyOS project with their types. It is categorised as a Read tool in the Mcp Harmonyos MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on harmonyos_list_modules? +

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

What risk level is harmonyos_list_modules? +

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

Can I rate-limit harmonyos_list_modules? +

Yes. Add a rate_limit block to the harmonyos_list_modules 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 harmonyos_list_modules completely? +

Set action: deny in the Intercept policy for harmonyos_list_modules. 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 harmonyos_list_modules? +

harmonyos_list_modules is provided by the Mcp Harmonyos MCP server (mcp-harmonyos). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
