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 clearly indicates this is a read operation ('Retrieves'), describes what gets returned ('structured configuration data showing all settings and their values'), and mentions the scope ('from any Splunk configuration file'). However, it doesn't mention authentication requirements, rate limits, or potential side effects like caching behavior.

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 well-structured with a clear purpose statement, usage guidelines, return value explanation, and organized parameter documentation. Every sentence adds value, and the information is front-loaded with the most important details first.

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 read operation with 4 parameters and no output schema, the description provides excellent coverage of purpose, usage, parameters, and return format. The only minor gap is the lack of explicit mention about authentication or permissions needed to access configuration files, which would be helpful given this is a system configuration tool.

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?

With 0% schema description coverage for all 4 parameters, the description provides comprehensive parameter semantics beyond what the schema offers. It explains each parameter's purpose, format requirements (e.g., 'without .conf extension'), optional nature, and filtering behavior, fully compensating for the schema's lack of descriptions.

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 ('Retrieves') and resource ('Splunk configuration settings from specified .conf files'), distinguishing it from sibling tools like list_config_files (which likely lists files rather than retrieving their contents) and get_config_spec (which likely provides specification details rather than actual settings).

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 access or inspect Splunk configurations, such as for troubleshooting, auditing, or understanding settings'), provides examples of specific use cases, and distinguishes it from alternatives by specifying it retrieves configuration data from .conf files rather than listing files or getting specifications.

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