Tools

3 tools for searching and retrieving CPSC consumer product recall data:

CPSC jurisdiction: Consumer products only — toys, electronics, furniture, appliances, children's products, tools, and clothing. Food and drugs (FDA), motor vehicles and tires (NHTSA), boats (USCG), and pesticides (EPA) are not in this database. Every response includes a jurisdiction note.

Data sourced from the U.S. Consumer Product Safety Commission via the CPSC public recalls API.

cpsc_search_recalls

Search recalls with flexible filtering across product, organization, and description fields.

• Filter by product name, manufacturer, retailer, importer, or description keyword — all fields are optional substring matches that combine with AND
• Date range filtering via date_start / date_end (ISO 8601)
• Client-side limit (1–200, default 20) applied after fetching all matching records
• Returns hazard descriptions, remedy options, remedy instructions, product list, UPCs, manufacturer/importer/retailer names, images, and the CPSC recall page URL
• Includes total_found and truncated fields for pagination awareness
• Note: the Hazard filter param is non-functional in the upstream API — use description_search for hazard-type keywords like "fire", "choking", or "burn"
• When manufacturer returns no results, try importer or retailer — many recalls list the importer as the primary organization

cpsc_get_recall

Full detail for a single CPSC recall by recall number.

• Accepts modern 5-digit recall numbers (e.g. "25043") and historical 1998–2001 records with letter suffixes (e.g. "99003a")
• Returns the complete record: full description, all hazard descriptions, remedy type and instructions, all product variants with unit counts, UPCs, incident/injury narrative, manufacturer and importer names, retailer names with sale date ranges, country of manufacture, images, and coordinated agency recall URLs
• Model numbers are typically embedded in the description text, not in a structured field
• Use cpsc_search_recalls or cpsc_get_recent to find a recall number first

cpsc_get_recent

Fetch the most recent CPSC recalls, ordered newest-first.

• Configurable look-back window of 1–365 days (default 30)
• Limit of 1–100 results (default 20)
• Always applies a date window — without one, the upstream API returns 9,800+ records
• Returns a lightweight record per recall: number, date, title, hazards, remedy types, product names, and CPSC URL
• Use cpsc_get_recall to retrieve full detail for any result

Features

Built on @cyanheads/mcp-ts-core:

• Declarative tool definitions — single file per tool, framework handles registration and validation
• Unified error handling — handlers throw, framework catches, classifies, and formats
• Pluggable auth: none, jwt, oauth
• Swappable storage backends: in-memory, filesystem, Supabase, Cloudflare KV/R2/D1
• Structured logging with optional OpenTelemetry tracing
• STDIO and Streamable HTTP transports

CPSC-specific:

• Full integration with the CPSC saferproducts.gov public recalls API
• Client-side filtering applied over complete API result sets for accurate total_found counts
• Jurisdiction boundary documented in every response — prevents misattribution of food, vehicle, or drug recalls

Agent-friendly output:

• Jurisdiction note on every response — agents can route callers to the correct agency (FDA, NHTSA, USCG, EPA) when the product is out of scope
• total_found + truncated fields on search/recent responses — agents can detect when results are clipped and suggest narrowing filters
• cpsc_url on every recall — authoritative source link for consumer verification

Getting started

Public Hosted Instance

A public instance is available at https://cpsc-recalls.caseyjhand.com/mcp — no installation required. Point any MCP client at it via Streamable HTTP:

{
  "mcpServers": {
    "cpsc-recalls-mcp-server": {
      "type": "streamable-http",
      "url": "https://cpsc-recalls.caseyjhand.com/mcp"
    }
  }
}

Self-Hosted / Local

Add the following to your MCP client configuration file.

{
  "mcpServers": {
    "cpsc-recalls-mcp-server": {
      "type": "stdio",
      "command": "bunx",
      "args": ["@cyanheads/cpsc-recalls-mcp-server@latest"],
      "env": {
        "MCP_TRANSPORT_TYPE": "stdio",
        "MCP_LOG_LEVEL": "info"
      }
    }
  }
}

Or with npx (no Bun required):

{
  "mcpServers": {
    "cpsc-recalls-mcp-server": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@cyanheads/cpsc-recalls-mcp-server@latest"],
      "env": {
        "MCP_TRANSPORT_TYPE": "stdio",
        "MCP_LOG_LEVEL": "info"
      }
    }
  }
}

Or with Docker:

{
  "mcpServers": {
    "cpsc-recalls-mcp-server": {
      "type": "stdio",
      "command": "docker",
      "args": ["run", "-i", "--rm", "-e", "MCP_TRANSPORT_TYPE=stdio", "ghcr.io/cyanheads/cpsc-recalls-mcp-server:latest"]
    }
  }
}

For Streamable HTTP, set the transport and start the server:

MCP_TRANSPORT_TYPE=http MCP_HTTP_PORT=3010 bun run start:http
# Server listens at http://localhost:3010/mcp

Prerequisites

• Bun v1.3.0 or higher (or Node.js v24+).
• No API key required — the CPSC public recalls API is freely accessible.

Installation

1. Clone the repository:

git clone https://github.com/cyanheads/cpsc-recalls-mcp-server.git

1. Navigate into the directory:

cd cpsc-recalls-mcp-server

1. Install dependencies:

bun install

1. Configure environment:

cp .env.example .env
# edit .env if needed — no required API keys

Configuration

All configuration is validated at startup via Zod schemas. Key environment variables:

No server-specific API keys are required. See .env.example for the full list of optional overrides.

Running the server

Local development

• Build and run the production version:

  # One-time build
  bun run rebuild

  # Run the built server
  bun run start:stdio
  # or
  bun run start:http

• Run checks and tests:

  bun run devcheck  # Lint, format, typecheck, security
  bun run test      # Vitest test suite

Docker

docker build -t cpsc-recalls-mcp-server .
docker run --rm -p 3010:3010 cpsc-recalls-mcp-server

The Dockerfile defaults to HTTP transport, stateless session mode, and logs to /var/log/cpsc-recalls-mcp-server. OpenTelemetry peer dependencies are installed by default — build with --build-arg OTEL_ENABLED=false to omit them.

Project structure

Development guide

See CLAUDE.md / AGENTS.md for development guidelines and architectural rules. The short version:

• Handlers throw, framework catches — no try/catch in tool logic
• Use ctx.log for request-scoped logging, ctx.state for tenant-scoped storage
• Register new tools in the createApp() arrays in src/index.ts
• Wrap external API calls: validate raw → normalize to domain type → return output schema; never fabricate missing fields
