Warn Notices MCP Server

warn-notices

US WARN Act layoff and plant-closure notices — the 60-day advance filings employers must make before a mass layoff — from state labor departments.

Part of Pipeworx — an MCP gateway connecting AI agents to 1866+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Coverage is partial on purpose, and every response says so. There is no national WARN database: the federal DOL neither collects nor publishes one, so employers file with the state where the site sits and each state publishes on its own terms. This pack covers the states that publish machine-readable data and reports exactly which those are.

Tools

Every response carries states_covered. An empty result distinguishes state_not_covered from no_matching_notices, because "Georgia isn't covered" and "this employer filed nothing" are different answers and only one of them is about the employer.

Coverage

Each state is registered in data_freshness separately (warn-ca, warn-il, …) so one stalled feed is visible instead of being hidden behind a fresher state's date.

Probed and not shipped

Recorded so nobody re-probes them:

• NJ — XLSX exists, but the state's own file is column-shifted on many rows (company names landing in the date column). Needs row-level repair.
• PA / WA / FL — real and current, but HTML only. PA is a nested accordion, WA an ASP.NET GridView needing __VIEWSTATE postbacks past page one, FL a paginated table. All scrapeable; none machine-readable.
• GA — no current public listing exists. The legacy search still answers but stops in 2013, and the modern site is an employer submission form with no public index.

Data sources

• California EDD — https://edd.ca.gov/en/jobs_and_training/Layoff_Services_WARN
• Illinois WorkNet — https://apps.illinoisworknet.com/iebs/layoff/publiclayoffs
• New York DOL — https://dol.ny.gov/warn-dashboard
• Ohio ODJFS — https://jfs.ohio.gov/ (annual warn-notice.csv asset)
• Texas Workforce Commission — https://data.texas.gov/d/8w53-c4f6

Ingest lives in workers/data-pipeline/src/datasets/warn.ts; the per-source traps are documented there. Table: warn_notices (migration 108).

Gotchas worth knowing

• Texas publishes no layoff-vs-closure flag. type is null for TX rather than guessed — an invented "Layoff" would read as reported fact.
• Texas lags. Its newest notice trailed the other states by ~2 months as of 2026-08-29. That is normal for this feed.
• Effective dates are not always dates. Several states publish a range or the word "various", so effective_date is set only when it parses and effective_date_as_published always carries what was actually written.
• Company names are free text. Search matches on a suffix-stripped form, so "Tesla" finds "Tesla, Inc."; matched_filed_names echoes back the exact strings matched so a caller can spot a loose match across sister entities.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "warn-notices": {
      "url": "https://gateway.pipeworx.io/warn-notices/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/warn-notices/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Both URLs reach the same gateway and the same 1866+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

No MCP client? Call it over HTTP

curl -X POST https://gateway.pipeworx.io/v1/tools/warn_search \
  -H 'Content-Type: application/json' \
  -d '{"state":"TX","min_employees":200,"since":"2026-01-01"}'

No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/warn_search. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.

Run it from npm

@pipeworx/mcp-warn-notices is a local stdio bridge to the Pipeworx gateway: your MCP client starts it with npx, and it forwards every call to the same https://gateway.pipeworx.io/warn-notices/mcp endpoint shown above. It needs network access; there is no offline mode.

{
  "mcpServers": {
    "warn-notices": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-warn-notices"]
    }
  }
}

Without a key it calls anonymously, capped at 50 calls a day. A free account raises that to 200 a day: get a key at https://pipeworx.io/signup and add "env": { "PIPEWORX_API_KEY": "<your key>" } to the server entry. The key is sent as a Bearer token, the same way a hosted connection sends it, so calls are metered and billed exactly as they are there.

It lists only this pack's tools by default. Set PIPEWORX_META_TOOLS=1 to also list ask_pipeworx and the other gateway-wide tools.

Behind an HTTPS proxy: Node's built-in fetch does not read HTTPS_PROXY by default. Newer Node releases honour it when NODE_USE_ENV_PROXY=1 is set; check your Node version's documentation.

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:

ask_pipeworx({ question: "your question about Warn Notices data" })

The gateway picks the right tool and fills the arguments automatically.
