SavePinner Pinterest URL Tools

SavePinner MCP

An MCP server for parsing, validating, classifying, and normalizing Pinterest URLs. It supports local stdio and public Streamable HTTP. The tools make no outbound network requests and do not download media.

Tools

Tool	Purpose
parse_pinterest_url	Return the URL kind, canonical URL, host, and type-specific identifiers.
normalize_pinterest_url	Convert a supported URL to canonical form and remove tracking parameters.
is_pinterest_url	Check whether a value is a supported Pinterest URL.

Supported URL kinds include Pin, pin.it, profile, board, and Ideas URLs across Pinterest country domains.

Run

Node.js 18 or newer is required.

npx -y savepinner-mcp

Client configuration

Add the server to an MCP client that supports local stdio servers:

{
  "mcpServers": {
    "savepinner": {
      "command": "npx",
      "args": ["-y", "savepinner-mcp"]
    }
  }
}

Remote MCP

Connect any Streamable HTTP client to the public endpoint:

https://savepinner-pinterest-url-mcp.chenxuanshimo.workers.dev/mcp

The endpoint is read-only and does not require authentication.

The public Pinterest URL validation guide explains the validation and normalization boundaries used by the tools.

Docker

Build and run the server as a local stdio container:

docker build -t savepinner-mcp .
docker run --rm -i savepinner-mcp

The runtime image executes as the unprivileged node user and does not require secrets, volumes, or network access.

Example

Calling parse_pinterest_url with:

https://de.pinterest.com/pin/987654321/?utm_source=share

returns:

{
  "kind": "pin",
  "originalUrl": "https://de.pinterest.com/pin/987654321/?utm_source=share",
  "normalizedUrl": "https://www.pinterest.com/pin/987654321/",
  "host": "de.pinterest.com",
  "pinId": "987654321"
}

Privacy and safety

• URL processing is local to the running server.
• The tools do not make outbound network requests.
• The server does not download media.
• Hostnames are checked against an exact Pinterest domain allow list.
• Lookalike domains and non-HTTPS URLs are rejected.

The URL parser is provided by pinterest-url-normalizer.
