MCP Server for Splunk

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does well by stating the tool 'requires no arguments' (parameter behavior) and describes the return format ('detailed app catalog with 54+ apps typically found in enterprise environments'). However, it doesn't mention pagination, rate limits, or authentication requirements.

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

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

The description is efficiently structured with three sentences: purpose statement, usage guidelines, and return format details. Every sentence adds value without redundancy. It's appropriately sized and front-loaded with the core functionality.

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

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

For a zero-parameter read-only tool with no annotations and no output schema, the description provides good context: clear purpose, usage guidelines, and return format details. However, it could be more complete by explicitly stating it's a read-only operation and mentioning any limitations or scope constraints.

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

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

The tool has 0 parameters with 100% schema description coverage. The description explicitly states 'This tool requires no arguments,' which adds valuable semantic context beyond the empty schema. This earns a 4 since it provides clear guidance about parameter expectations.

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

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

The description clearly states the tool's purpose with specific verb ('Retrieve') and resource ('comprehensive inventory of all installed Splunk applications'), including detailed metadata fields. It distinguishes itself from siblings like 'list_dashboards' or 'list_indexes' by focusing specifically on applications.

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

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

The description explicitly states when to use this tool ('when you need to list all apps in the Splunk environment') and provides concrete use cases ('auditing, management, or troubleshooting compatibility'). It also distinguishes from alternatives by specifying it lists 'all installed' apps without filtering.

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