health

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

No annotations exist, so the description carries the burden; it does convey that this is a non-mutating status probe returning three categories of information, which is the key behavioral fact. It omits any mention of cost, latency, or whether failures surface as errors versus degraded status values.

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?

Front-loaded purpose sentence followed by return summary and a one-line example; nothing is redundant. The example for a zero-arg call is slightly ceremonial but harmless.

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?

With no output schema, the description does well to enumerate the returned fields, but it leaves unresolved how this differs from other diagnostic siblings (test_connection, get_rootdse_info, get_domain_info) — the main ambiguity an agent faces in this 40+ tool list.

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 takes zero parameters, so there is nothing for the description to disambiguate; baseline applies. The example call correctly shows an empty argument list.

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?

States a specific verb and resource ('Health check for Active Directory MCP server') and enumerates what it reports: server status, LDAP connectivity, system health. However, it never distinguishes itself from siblings like test_connection or get_domain_info, which plausibly overlap with 'LDAP connectivity' reporting.

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?

'Essential for monitoring and alerting' implies a usage context (operational monitoring) but gives no explicit when-to-use versus test_connection, nor any exclusions. The agent must infer the boundary itself.

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