CanWeShip MCP

An MCP server providing editorially maintained prototype U.S. domestic shipping guidance for USPS, UPS, and FedEx. It helps agents determine if specific products like perfume, batteries, and aerosols can be shipped, including hazmat fee rules and carrier-specific restrictions.

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.

list_products — List Supported Products
Advertised by the server during the last successful anonymous check.
Advertised read-only

List the products CanWeShip checks, each with the first sentence of its answer, verification date and guide URL. Pass query to search product names, aliases and named products such as iPhone 15 or aerosol deodorant; each named product says which product check answers for it.

get_product_guidance — Get Product Shipping Guidance
Advertised by the server during the last successful anonymous check.
Advertised read-only

Get preliminary U.S. domestic shipping guidance for one product: the answer with claim-level source IDs, the facts check_product accepts (ids, types, allowed values), carrier context, review dates and the cited official sources. Accepts product slugs, named products and aliases. FAQs, rule evidence and the full source list are left out unless requested with include.

check_product — Evaluate Product Shipping Facts
Advertised by the server during the last successful anonymous check.
Advertised read-only

Evaluate supplied product facts through the same deterministic USPS, UPS and FedEx rule runtime used by the CanWeShip checker. Use the fact ids from get_product_guidance questions. Unknown or invalid facts are ignored and never treated as clearance; next_questions lists the facts still open, in the order the checker asks them.

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 canweship-mcp https://canweship.com/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 canweship-mcp --url https://canweship.com/mcp

Cursor

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

Cline

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

VS Code

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

Windsurf

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