PDF Content Search MCP

add_folder

Add a folder to the PDF search index by providing its absolute path, enabling full-text search of all documents inside.

Instructions

Add a folder to the indexed search folders by absolute path. The path must exist and be a directory.

Input Schema

pathYesAbsolute path to the folder to index.
Behavior2/5

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

No annotations provided, so description carries full burden. It discloses that the path must be an existing directory and that the folder is added to indexed search folders, but does not mention behavior on duplicates, error handling, or side effects like triggering reindexing.

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?

Two concise sentences with no wasted words. The key information is front-loaded and efficiently communicated.

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

Completeness3/5

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

Given no output schema and simple operation, the description covers the primary purpose and precondition. However, it lacks details about return value, status on success/failure, and behavior for edge cases (e.g., already indexed). So it is minimally adequate but leaves gaps.

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

Parameters4/5

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

Schema coverage is 100% with description 'Absolute path to the folder to index.' The tool description adds the constraint 'The path must exist and be a directory,' which provides additional semantic meaning beyond the schema.

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 verb 'Add', the resource 'folder to the indexed search folders', and the condition 'by absolute path'. It distinguishes from sibling tool 'delete_folder'.

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

Usage Guidelines2/5

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

No explicit guidance on when to use this tool versus alternatives. Only includes a precondition (path must exist and be a directory) but does not discuss scenarios like avoiding adding already-indexed folders or alternative indexing tools.

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