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 indicate this is a safe read operation (readOnlyHint=true, destructiveHint=false). The description adds transparency by listing return fields and mentioning the optional include_inactive parameter, but goes little beyond the 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, front-loaded, no redundant information. Every word adds value.
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?
Given the simple tool (1 optional param, no output schema), the description fully covers what the agent needs: action, scope, return fields, and use cases. No gaps.
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 schema has 100% description coverage for the single parameter (include_inactive). The description only implies its effect by stating 'active subscriptions.' Baseline 3 is appropriate since schema covers the parameter meaning.
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 clearly states the action (list), resource (subscriptions), and scope (caller's active). It also lists the return fields. While it doesn't explicitly differentiate from siblings like subscribe/unsubscribe, the purpose is unambiguous.
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?
The description provides explicit use cases: 'review what you're monitoring before adding more or to find an id to cancel.' This gives contextual guidance, though it does not discuss when not to use or alternatives.
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.
The vast majority of tools (e.g., ask_pipeworx, ask_pipeworx_grounded, bet_research, polymarket_arbitrage, etc.) are unrelated to Metabolights and overlap heavily with each other in purpose. Only two tools (get_study and search_studies) are clearly distinct and relevant to the server's stated domain.
Tool names are highly inconsistent, mixing snake_case (get_study, search_studies), camelCase (ask_pipeworx), and varied verb styles (e.g., validate_claim vs bet_research). No consistent pattern across the set.
With 28 tools, the server is extremely overpopulated for its stated purpose (Metabolights). Only 2 tools actually pertain to metabolomics study access, while the remaining 26 are general-purpose or unrelated (e.g., bet_research, polymarket_edges), making the count highly inappropriate.
The Metabolights domain severely lacks completeness: only search_studies and get_study are provided, with no create, update, delete, or upload functionality. The server fails to cover essential operations for its supposed domain.
