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=true and idempotentHint=true, so the description adds value by listing return fields and default filtering (active subscriptions). No contradiction 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, efficient and front-loaded. The first sentence states the core purpose, the second adds usage guidance. No unnecessary 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?
With annotations covering safety and schema covering parameters, the description adds return field details and usage context. It is complete for a simple list tool, though it could mention response format or pagination if applicable.
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% with the single boolean parameter clearly described. The description does not elaborate further on the parameter beyond the schema context, so 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?
The description clearly states the tool lists the caller's active subscriptions, specifying return fields (id, type, params, etc.). This distinguishes it from sibling tools subscribe and unsubscribe, which perform different actions.
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 provides use cases: 'Use this to review what you're monitoring before adding more or to find an id to cancel.' This tells the agent when to use this tool versus 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.
Several tool clusters overlap heavily: ask_pipeworx, ask_pipeworx_beta, and ask_pipeworx_grounded are near-identical in purpose, and the five polymarket_* tools all target prediction-market analysis. The presence of a broad Pipeworx data layer alongside Wayback-specific tools under one server name further blurs boundaries.
Most tools use snake_case, but the pattern varies: many follow verb_noun (get_snapshot, list_snapshots, resolve_entity, validate_claim), while others are noun_noun (entity_profile, polymarket_edges, pipeworx_feedback, bet_research). Suffixes like _beta and _grounded are used inconsistently, and some names are long and descriptive while others are terse.
34 tools is far more than what a Wayback Machine server should need, and most tools (Pipeworx data queries, prediction-market analysis, memory, subscriptions) have nothing to do with the Wayback Machine. The server's stated purpose appears narrow, but the tool set is bloated with unrelated functionality.
For the Wayback Machine domain, only three tools are relevant (get_capture_count, get_snapshot, list_snapshots), and obvious operations like saving/archiving a URL, comparing snapshots, or handling deleted captures are missing. The Pipeworx-related tools are broad but not clearly aligned with the Wayback theme, so the core purpose is under-served.
