install_catalog_app

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

// WHEN AI AGENTS USE THIS TOOL

AI agents use install_catalog_app to create or modify resources in Ilumin. 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.

// WHY ENFORCE A POLICY ON INSTALL_CATALOG_APP

Without a policy, an AI agent could call install_catalog_app 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 Ilumin.

// RECOMMENDED POLICY

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

What does the install_catalog_app tool do? +

Installs an application from the Ilumin App Catalog. IMPORTANT: Before calling this tool, you must have confirmed with the user that they want to install this specific app. If the app requires environment variables (as indicated by 'list_catalog'), you MUST ask the user for these values (e.g., APP_PASSWORD, APP_USER, APP_EMAIL, APP_API_KEY) before proceeding. This tool is ONLY for apps found in the catalog. Requires the server domain and the app slug.. It is categorised as a Write tool in the Ilumin MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on install_catalog_app? +

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

What risk level is install_catalog_app? +

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

Can I rate-limit install_catalog_app? +

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

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

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