Recent Changes

recent_changes
Read-onlyIdempotent

"What's new with X" / "latest on Y" / "what happened to Z this week / month / quarter" / "updates on Acme" / "news on Tesla recently" / "what's happening with Apple" — change feed for a company in the last N days/weeks/months in ONE parallel call. Fans out to SEC EDGAR (filings since since), GDELT→GNews fallback (news mentions in window — GDELT preferred, GNews when rate-limited or 5xx), USPTO (patents granted; PatentsView API sunset May 2025 so this soft-fails until reactivated). since accepts ISO date ("2026-04-01") or relative shorthand ("7d", "30d", "3m", "1y"). Returns structured changes[] grouped by source + total_changes count + pipeworx:// citation URIs. Use entity_profile instead when you want the static profile (filings + fundamentals + LEI + patents) regardless of window.

TDQS

A4.9/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already indicate readOnly, openWorld, idempotent, and non-destructive. The description adds significant operational detail: parallel fan-out to multiple sources, GDELT→GNews fallback, USPTO soft-fail due to API sunset, and return structure. This goes well beyond annotations and sets correct expectations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Dense but efficient: starts with query examples, then states the core function, lists sources, and closes with an alternative. No fluff; every sentence adds essential information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with no output schema, the description fully covers the return shape (changes[] grouped by source, total_changes, citation URIs), the supported time windows, the fallback behavior, and the limitation (patents soft-fail). This is a complete operational picture for a complex aggregation tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema covers all three parameters at 100%, so baseline is 3. The description adds value by explaining `since` formats ('ISO date' or 'relative shorthand') with examples and recommending '30d' or '1m' for typical monitoring. This extra guidance justifies a 4.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Clear verb ('change feed') and resource ('company'), with concrete example queries that illustrate the intent. Explicitly distinguishes itself from entity_profile, which covers static profiles.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides explicit 'when to use' via example natural-language queries, and an explicit alternative ('Use entity_profile instead when you want the static profile...'). Also explains fallback behavior and window syntax, giving clear context for selection.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A3.9/5.0
Disambiguation2/5

Several tool families have ambiguous boundaries: ask_pipeworx, ask_pipeworx_beta, and ask_pipeworx_grounded are three variants of the same router (with beta currently identical), and the six polymarket tools plus bet_research heavily overlap in scanning and pricing edges. discover_tools, suggest_questions, and deep_research also all function as 'what should I query' entry points. Agents will struggle to select the right tool without carefully reading long descriptions.

Naming Consistency3/5

Many tools follow a clear verb-first snake_case pattern (get_article_extract, resolve_entity, subscribe, validate_claim), and families like ask_pipeworx_* and polymarket_* are internally consistent. However, notable noun-phrase outliers such as entity_profile, deep_research, bet_research, recent_changes, pipeworx_feedback, and polymarket_edge_tracker break the convention. The naming is readable but not predictable across the full set.

Tool Count2/5

36 tools is well over the 25+ threshold for a typical MCP server, and for a server named 'wikipedia' it is especially disproportionate: only 5 tools actually deal with Wikipedia while 31 are Pipeworx data, prediction-market, memory, subscription, and feedback utilities. The count reflects a broad all-in-one platform crammed into a Wikipedia-labeled surface rather than a well-scoped server. This is a significant scope mismatch.

Completeness4/5

The Wikipedia portion is reasonably complete for read-only lookup: search, summary, sections, full extract, and random discovery cover common encyclopedic questions without dead ends. The broader Pipeworx surface is also extensive, with query, grounded verification, deep research, entity resolution/profile/comparison, claim validation, memory, and subscription lifecycle tools. Minor gaps remain (no article categories/history, no update for subscriptions, no direct fetch of a citation URI), but they are workable.
