Neiss MCP server

@pipeworx/neiss

National WEIGHTED estimates of consumer-product-related emergency-department injuries in the US, from CPSC's injury-surveillance system — "how many people were injured by X", "what products injure people the most". Separate from the cpsc pack, which covers CPSC's RECALL database (saferproducts.gov); this is the injury-surveillance side.

Part of Pipeworx — an MCP gateway connecting AI agents to 1807+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Tools

— national weighted estimate for one product, one year or a year range, plus the underlying sample size. Flags any estimate built from a small sample as unstable rather than reporting it as precise.

• neissinjuries(productcode | product, year | fromyear/toyear, age_range?)

weighted injury estimate for one year.

• neisstopproducts(year?, age_range?, limit?) — rank products by national

by keyword to find the exact code neiss_injuries wants. Entirely local, no live call.

• neissproductcodes(query, limit?) — search the ~800 product/activity codes

Auth

Keyless.

Data sources

representative sample of hospital emergency departments, operated by CPSC for 45+ years, that produces the national estimates behind "how many X injuries" questions. CPSC publishes a complete calendar year of emergency-department-visit records at a time, not a per-request query API; the per-product, per-year weighted estimates these tools serve are computed OFFLINE from CPSC's own published annual files — see "Updating the data" below. The product/activity code list is CPSC's own NEISS Coding Manual (Appendix H).

Updating the data

The estimate store holds (year, productcode, agebucket) rows, not case-level records — nothing patient-identifying is ever loaded. To add a year:

# 1. Download + aggregate (safe to run anywhere; no credentials needed).
#    Downloads CPSC's own annual files directly; takes ~1 minute for 2 years.
node scripts/neiss/aggregate-neiss.mjs --years 2025 --out /tmp/neiss-2025.json

# 2. Load into the store (needs `wrangler` logged in to the production
#    Cloudflare account — run by whoever holds that, not by the pack author).
node scripts/neiss/load-data.mjs --file /tmp/neiss-2025.json

A case counts toward EVERY product code it lists (NEISS allows up to three per case), matching CPSC's own per-product convention — a two-product case is not split 50/50. age_bucket 'all' sums every case for that product regardless of age, including unknown age; the other buckets (0-4/5-14/15-24/25-44/45-64/65+) only include cases with a known age. Age under 2 years is coded by CPSC in completed months, not years — the aggregator converts both to fractional years before bucketing.

Estimates from fewer than ~20 sampled cases are flagged unstable_estimate rather than silently reported as precise, per CPSC's own convention for small cells.

Quick Start

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

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

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/neiss/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — askpipeworx, discovertools, 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.
