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 read-only, idempotent, non-destructive behavior. Description adds return field details, providing context beyond annotations without contradiction.
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 with purpose and return fields, no wasted words.
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 tool with one optional parameter, good annotations, and no output schema, description fully covers what the agent needs to 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 covers the one parameter fully (100% coverage). Description does not add parameter-specific info, but baseline 3 is appropriate.
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?
Clearly states verb 'List', resource 'subscriptions', and specifies returned fields. Distinguishes from sibling tools like subscribe and unsubscribe.
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?
Explicitly states when to use: 'to review what you're monitoring before adding more or to find an id to cancel'. Lacks explicit exclusions but sufficient for a simple list tool.
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.
Many tools overlap heavily: ask_pipeworx, ask_pipeworx_beta, ask_pipeworx_grounded, deep_research, and validate_claim all answer factual queries with subtle differences, and the Polymarket suite (bet_research, polymarket_edges, polymarket_arbitrage, polymarket_fill_risk, polymarket_edge_tracker) has fine-grained distinctions that are hard to separate. The single Barcelona events tool is isolated and unrelated to the rest, adding to agent confusion.
Most tool names use snake_case and many follow a verb_noun pattern, but there are notable inconsistencies: noun-first names (entity_profile, polymarket_arbitrage, pipeworx_trending) and modifiers like beta/grounded on ask_pipeworx introduce non-uniformity. Overall the set is readable but not consistently predictable.
With 32 tools, the set is beyond the well-scoped 3-15 range. The count is especially inappropriate for a server named 'Barcelona Events' because only one tool actually relates to Barcelona events; the other 31 are a broad data-research and utility collection with no clear connection to the server's apparent purpose.
For a server named 'Barcelona Events', the surface is severely incomplete: it offers a single events search tool with no create, update, delete, detail, venue, or organizer operations. Even interpreting the domain broadly, the mismatch between the server name and the tool set leaves a critical gap between user expectation and actual capability.
