Medium Risk

apps_update

Update mutable fields of an existing Countly app (name, country, timezone, category) via /i/apps/update. Only supplied fields change. For creating a new app use apps_create.

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

AI agents use apps_update to create or modify resources in Countly. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

Without a policy, an AI agent could call apps_update repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Countly.

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

What does the apps_update tool do? +

Update mutable fields of an existing Countly app (name, country, timezone, category) via /i/apps/update. Only supplied fields change. For creating a new app use apps_create.. It is categorised as a Write tool in the Countly MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on apps_update? +

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

What risk level is apps_update? +

apps_update is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit apps_update? +

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

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

apps_update is provided by the Countly MCP server (countly-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
