Rattlewatch MCP

Rattlewatch provides a community MCP server for AI agents to look up US product recalls from CPSC and FDA data. It returns only records pinned to official sources or an explicit negative, ensuring no hallucinated answers. It supports searching recalls, checking market-entry requirements, listing recent changes, and verifying claims against its append-only store.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

search_recalls
Advertised by the server during the last successful anonymous check.
Advertised read-only

Search official US recall records by product name, brand, model, or UPC. Covers CPSC consumer products and FDA food, drug and device enforcement. Returns only cited records from the store, each with a source URL and a match score. If nothing matches, returns an empty list rather than guessing.

get_requirement
Advertised by the server during the last successful anonymous check.
Advertised read-only

Get cited market-entry requirements for a product subject in a given market (e.g. subject='childrens_products', market='US'). This is a small curated set, not a full regulatory database: CPC, CPSC eFiling, EU GPSR, CE marking, REACH SVHC, RoHS and California Prop 65. Returns each fact with its official citation URL and last-verified date.

Advertised by the server during the last successful anonymous check.
Advertised read-only

List recall and requirement changes since an ISO-8601 timestamp (e.g. '2026-09-01T00:00:00+00:00'). Includes newly published recalls and rule changes, each with its source URL.

verify
Advertised by the server during the last successful anonymous check.
Advertised read-only

Check a claim or product query against the store. Returns only cited records (recalls and requirements) that match. Explicitly reports 'no verified record' when nothing matches -- it never synthesizes an answer, so absence means 'not in the store', not a negative claim.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http rattlewatch-mcp https://rattlewatch.rattled.ca/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add rattlewatch-mcp --url https://rattlewatch.rattled.ca/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable rattlewatch-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "rattlewatch-mcp": {
      "url": "https://rattlewatch.rattled.ca/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "rattlewatch-mcp": {
      "type": "streamableHttp",
      "url": "https://rattlewatch.rattled.ca/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start rattlewatch-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "rattlewatch-mcp": {
      "type": "http",
      "url": "https://rattlewatch.rattled.ca/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http rattlewatch-mcp https://rattlewatch.rattled.ca/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.
Claude Desktop configuration

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "rattlewatch-mcp": {
      "serverUrl": "https://rattlewatch.rattled.ca/mcp"
    }
