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, openWorldHint, idempotentHint, and destructiveHint. The description adds context about return fields and default filtering to active subscriptions, which complements but does not contradict 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?
The description is two sentences, front-loading the purpose and usage guidance without any extraneous words, achieving high conciseness and structural efficiency.
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?
Despite the lack of an output schema, the description lists the return fields (id, type, etc.) and provides usage context, making it complete for a simple read tool with one optional parameter.
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?
With 100% schema coverage, the input schema already describes the 'include_inactive' parameter. The description implicitly references it by mentioning 'active subscriptions', but does not add new semantic detail beyond the schema.
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 'List the caller's active subscriptions' with a specific verb and resource, and the list of sibling tools includes 'subscribe' and 'unsubscribe', distinguishing this tool as a read operation to review existing subscriptions.
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 explicitly advises using this tool 'to review what you're monitoring before adding more or to find an id to cancel', providing clear guidance on when to use it and linking to sibling tools for adding and canceling.
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.
ask_pipeworx, ask_pipeworx_beta, and ask_pipeworx_grounded form a tight cluster, and the beta variant is explicitly identical to ask_pipeworx today. Several meta-tools like discover_tools, suggest_questions, and deep_research also overlap in discovery-oriented usage, so an agent must read carefully to pick the right one.
Names are uniformly lowercase with underscores and mostly descriptive, but the conventions are mixed: verb_noun tools like validate_claim and list_subscriptions sit alongside noun_phrase tools like entity_profile and polymarket_arbitrage, plus bare verbs like remember and subscribe. It is readable but not a single predictable pattern.
36 tools is well above the 25+ threshold, and the surface spans unrelated domains: EPA ECHO data, general Pipeworx research, Polymarket betting, memory, npm scanning, and AI visibility checks. For a server named 'Epa Echo', most tools feel out of scope and the collection seems like several separate servers merged together.
The EPA ECHO subset provides a solid facility-search, violations, compliance-history, and enforcement-action lifecycle. The broader Pipeworx surface also covers lookups, grounded answers, deep research, entity profiling, subscriptions, and memory, with only minor workaround-level gaps such as no dedicated ECHO permit/emissions detail tool.
