Impreza Host MCP Server

impreza_list_apps

List one-click install apps from the Impreza curated catalog, including Vaultwarden, n8n, Nextcloud, and more. Filter by name, category, or tags to find pre-packaged manifests for quick deployment.

Instructions

List apps available in the Impreza curated catalog (Vaultwarden, n8n, Nextcloud, etc.). These are pre-packaged manifests the customer can install with one click. For non-catalog apps the customer built themselves, use impreza_deploy_custom instead.

categoryNoOptional category filter (e.g. "media", "productivity").
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden. It describes the listing behavior but does not mention authentication requirements, rate limits, or the return format. For a simple read-only list tool, this is adequate but lacks depth.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences, front-loads the core purpose, and wastes no words. The distinction from the sibling tool is efficiently integrated.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description should explain what the return value contains (e.g., app objects with fields like name, category, tags). It does not mention pagination or limits, leaving the agent without critical information for handling results.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% and the description only restates the filter options without adding new meaning. It does not explain how the filters combine or provide examples beyond what the schema already defines.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool lists apps from the Impreza curated catalog, provides examples (Vaultwarden, n8n, Nextcloud), and distinguishes it from the sibling tool impreza_deploy_custom for non-catalog apps.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explicitly tells when to use this tool (for catalog apps) and when to use impreza_deploy_custom instead (for custom apps), providing clear decision context.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
