list_subscriptionsList the caller's active subscriptions. Returns id, type, params, created_at, last_fired_at, fire_count for each. Use this to review what you're monitoring before adding more or to find an id to cancel.
| Name | Required | Description | Default |
|---|---|---|---|
| include_inactive | No | Include cancelled subscriptions in the response (default false). |

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint and destructiveHint=false, so the safety profile is known. The description adds useful context about caller-scoped data, default 'active' filtering, and the exact return fields, going beyond 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 with no filler. The action and return information are front-loaded, and the second sentence provides actionable use cases, making it optimally concise.
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 a simple list tool with one optional parameter and no output schema, the description covers purpose, return fields, and use cases. It is self-sufficient for an agent to select and invoke correctly.
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 coverage is 100% for the only parameter (include_inactive), so the schema fully documents it. The description adds no additional parameter detail, meeting the baseline for high schema coverage.
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 uses a specific verb ('List') and resource ('the caller's active subscriptions'), clearly distinguishing it from sibling tools like subscribe/unsubscribe. It also enumerates return fields, providing precise scope.
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?
Explicit use cases are stated: 'review what you're monitoring before adding more' and 'to find an id to cancel', which implicitly reference subscribe and unsubscribe as alternatives. This gives direct when-to-use guidance.
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.
Several clusters of tools overlap heavily: ask_pipeworx/ask_pipeworx_beta/ask_pipeworx_grounded/deep_research all answer questions, and the five polymarket_* tools require careful reading to distinguish. The three UK police tools are clear, but they sit among many near-duplicate data-query and memory utilities.
Mixed conventions: snake_case verb_noun (get_crimes) coexists with brand-style names (ask_pipeworx), noun phrases (polymarket_arbitrage), and bare verbs (forget, recall). The polymarket_* and ask_pipeworx_* families are internally consistent, but the overall set lacks a single pattern.
34 tools is heavy, and only three relate to the server's stated ukpolice domain, while the rest form a general-purpose data platform. Many meta-tools (suggest_questions, discover_tools, pipeworx_feedback, pipeworx_trending, memory) add bulk relative to the core purpose.
For the actual Pipeworx scope, coverage is strong: query, research, comparisons, subscriptions, memory, and feedback are all present. But for the ukpolice name, it is missing many UK police endpoints (neighborhoods, stop-and-search, etc.) and has no write/update operations, so the surface feels mismatched.
