unsubscribeCancel a subscription by id. Ownership is enforced — you can only cancel your own subscriptions. The row is deactivated (not deleted) so its historical events stay available via recent_alerts.
| Name | Required | Description | Default |
|---|---|---|---|
| id | Yes | Subscription id (uuid) returned by subscribe. |

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations show readOnlyHint=false and destructiveHint=false, but description adds critical info: ownership enforcement, row deactivation (not deletion), and historical data preservation. All neutral with annotations.
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?
Two sentences totaling ~30 words, front-loaded with action. Every word adds value with no redundancy.
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?
For single-parameter tool with no output schema, description covers ownership, side effect (deactivation), and historical data retention. Fully adequate for agent selection and invocation.
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 covers 100% of parameters with 'id' description. Description adds that the id comes from 'subscribe', providing useful lineage context beyond schema alone.
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?
Description explicitly states 'Cancel a subscription by id' with clear verb-resource pairing. Distinguishes from sibling tools like 'subscribe' and 'list_subscriptions' by noting ownership enforcement and deactivation behavior.
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?
Indicates when to use (cancel own subscription), ownership prerequisite, and what happens to historical events (available via 'recent_alerts'). Provides clear context with alternative reference.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Most tools have distinct purposes with clear descriptions, but ask_pipeworx_beta is nearly identical to ask_pipeworx, and the presence of several meta-tools may cause slight confusion. Overall, an agent can differentiate most tools.
Tool names consistently use lowercase_with_underscores and follow an action_domain pattern (e.g., validate_claim, scan_competitor_ai_presence). There is a mix of verb-noun and noun-verb, but the pattern is predictable and readable.
33 tools is on the higher end, but given the broad scope (finance, drugs, prediction markets, data retrieval, memory), the count is reasonable. However, the server name 'Hurricanes' suggests a narrower focus, making the count feel excessive for that domain.
The tool set covers a wide range of data domains and includes meta-tools for discovery, grounded answers, and subscriptions. Minor gaps exist (e.g., no non-US company data), but overall the surface is comprehensive for a general-purpose data server.
