IMCP - Insecure Model Context Protocol

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 mentions security aspects like 'confidential documents' and 'role-based access controls', which hints at authentication needs, but does not specify required permissions, rate limits, or what operations are performed (e.g., read vs. write). This leaves significant gaps for a tool handling sensitive data.

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 concise and front-loaded, with two sentences that efficiently cover the tool's domain and key features. There is no unnecessary information, and it uses emojis and clear language, though it could be slightly more structured for optimal clarity.

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?

Given the tool's complexity (handling sensitive enterprise documents) and lack of annotations or output schema, the description is incomplete. It does not explain what the tool returns, error conditions, or detailed behavioral traits, leaving the agent with insufficient information for safe and effective use.

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?

Schema description coverage is 100%, so the schema already documents both parameters ('documentId' and 'metadata'). The description adds no additional meaning beyond what the schema provides, such as explaining the format of 'metadata' or how parameters interact. Baseline 3 is appropriate as the schema handles the heavy lifting.

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 states the tool is for 'secure document access and management' and mentions handling specific document types, which provides a general purpose. However, it lacks a specific verb (e.g., 'retrieve', 'update') and does not clearly distinguish from sibling tools like 'search-documents' or 'enterprise-security-vault', making it vague in comparison.

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 mentions 'role-based access controls' and 'enterprise environments', implying context, but provides no explicit guidance on when to use this tool versus alternatives like 'search-documents' or 'enterprise-security-vault'. There are no when-not or alternative usage statements, leaving the agent with minimal direction.

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