ds_ping

Verify the MCP server is alive by echoing a message or 'ok' and returning the running mesa-mcp version, without requiring iRODS access.

Instructions

Liveness check. Echoes back the supplied message (or 'ok') and the running mesa-mcp version. No iRODS access required.

Tool call template

TDQS

A4.5/5.0
Behavior4/5

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

No annotations are provided, so the description carries the burden, and it does disclose meaningful behavior: the message is echoed, 'ok' is the fallback, the version is returned, and no iRODS session/credentials are needed. It is not exhaustive (no latency/timeout caveats), but for a stateless ping this is solid disclosure.

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?

Three short sentences, front-loaded with the purpose, then behavior, then the constraint. Every sentence carries information; nothing is redundant.

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

Completeness5/5

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

An output schema exists, so return values need not be detailed, yet the description still summarizes them (echoed message + version). For a zero-required-parameter liveness tool, nothing needed to invoke it correctly is missing.

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 description coverage is 0% and the single 'message' property has no schema description, so the description must compensate. It does: it explains that the supplied message is echoed and that 'ok' is used when it is omitted, which resolves the nullable default.

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?

States a specific verb and resource: a liveness/smoke check that echoes a message and the running mesa-mcp version. This is clearly distinguishable from every sibling, which all perform iRODS/data operations, and the 'no iRODS access required' clause reinforces the distinction.

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

Usage Guidelines4/5

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

The 'Liveness check' framing plus 'No iRODS access required' gives a clear condition for use: call it to verify the server is reachable when no data access is needed. It stops short of explicitly naming when not to use it or contrasting with an alternative, but no sibling overlaps this role.

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