Pingstack monitors cron jobs and scheduled tasks with heartbeat checks, and checks websites, TCP ports, DNS records, SSL certificates and domain expiry. This MCP server lets your agent create and update checks, organize dashboards, and read incidents, uptime, run history and latency. Browser sign-in, no API key needed.
Scored across 1 tool
With only one tool, there is no possibility of overlap or misselection. Its purpose, reading account capabilities, is clearly stated and distinct.
The single tool uses a clear snake_case verb_noun pattern: get_account_capabilities. There are no competing naming conventions to create inconsistency.
A single read-only introspection tool is too thin for a platform whose description references probes, dashboards, plan limits, usage, and billing. It suggests a much broader domain than the one exposed operation supports.
The surface only reads account metadata and capabilities. There are no tools to create, list, update, delete, or run checks/probes, manage dashboards, or handle other core Pingstack lifecycle operations, creating severe gaps.
Read the bound account's capabilities: supported check kinds and their fields, plan limits, usage, active probe locations, the user's time zone, features and billing guidance. features.dashboard_domains is true when public dashboards can be served on a Pingstack subdomain or custom domain. Usage is a snapshot. billing.upgrade_url is null when self-service upgrades are unavailable.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered. The description adds modest value with the snapshot caveat and the meaning of billing.upgrade_url being null, but those are return-value semantics rather than behavior beyond the annotations, and it says nothing about permissions, auth scope, or rate limits.
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 first sentence front-loads the full inventory of returned data and the remaining sentences resolve specific ambiguities (dashboard_domains, snapshot usage, null upgrade_url). It is dense but every sentence carries information, though the field-level explanations lean on territory the output schema already covers.
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 an output schema present, return values needn't be documented, and the annotations cover the safety profile, so the description is more than sufficient for a zero-argument read. The only shortfall is that it explains fields the output schema already defines instead of covering operational context such as caching or call frequency.
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; the baseline for a no-parameter tool applies. No misleading parameter hints are present.
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 opens with a specific verb and resource ("Read the bound account's capabilities") and then enumerates the concrete contents: check kinds and fields, plan limits, usage, probe locations, time zone, features and billing guidance. An agent knows exactly what data comes back without opening the output schema.
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?
There are no sibling tools and no explicit when-to-use guidance, but the intent is clearly implied: call this to discover what the account supports before configuring checks. The "Usage is a snapshot" note hints at freshness considerations but doesn't say whether or how often to re-call.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
