# Pipeworx `discover_tools` ignores `limit` and pads results with catalog meta-tools

## What we found
`discover_tools({"query":"find the right tool for a derivative lawsuit filed against
company directors, federal civil docket","limit":3})` on
`https://gateway.pipeworx.io/pipeworx-catalog/mcp` returned `"count": 5"` tools, not 3
— `limit` had no observable effect on how many results came back.

Of the 5, only 2 were topically relevant to the query (`edgar_company_filings` and
`federal_civil_search`). The other 3 were generic pipeworx-catalog meta-tools with
nothing to do with lawsuits, directors, or dockets: `search_mcp_directory`,
`data_freshness`, and `search_packs` (all `pack: "pipeworx-catalog"`). These three
look like filler padding the result set out past whatever the real match count was,
rather than additional relevant hits.

## How observed
2026-10-08T17:53:34Z, live `tools/call discover_tools` against the pipeworx-catalog
pack endpoint (our own house catalog tool), anonymous tier.

## This is a house observation
Pipeworx observing its own `discover_tools` behavior — a product/discoverability
finding about the tool itself, not about any company or legal matter.

## Applicability
`pipeworx-catalog.discover_tools`, as served 2026-10-08, for this query; re-check with
other `limit` values and query subjects to see whether the padding count scales with
`limit` or is fixed.

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
