CVE-2022-29244low · fixedCVSS 3.1

Packing does not respect root-level ignore files in workspaces

### Impact `npm pack` ignores root-level `.gitignore` & `.npmignore` file exclusion directives when run in a workspace or with a workspace flag (ie. `--workspaces`, `--workspace=<name>`). Anyone who has run `npm pack` or `npm publish` with workspaces, as of [v7.9.0](https://github.com/npm/cli/releases/tag/v7.9.0) & [v7.13.0](https://github.com/npm/cli/releases/tag/v7.13.0) respectively, may be affected and have published files into the npm registry they did not intend to include. ### Patch - Up

CVE-2018-7408low · fixedCVSS 3

Incorrect Permission Assignment for Critical Resource in NPM

An issue was discovered in an npm 5.7.0 2018-02-21 pre-release (marked as "next: 5.7.0" and therefore automatically installed by an "npm upgrade -g npm" command, and also announced in the vendor's blog without mention of pre-release status). It might allow local users to bypass intended filesystem access restrictions because ownerships of /etc and /usr directories are being changed unexpectedly, related to a "correctMkdir" issue.

CVE-2013-4116info · fixed

Local Privilege Escalation in npm

Affected versions of `npm` use predictable temporary file names during archive unpacking. If an attacker can create a symbolic link at the location of one of these temporary file names, the attacker can arbitrarily write to any file that the user which owns the `npm` process has permission to write to, potentially resulting in local privilege escalation. ## Recommendation Update to version 1.3.3 or later.

CVE-2020-15095low · fixedCVSS 3.1

npm CLI exposing sensitive information through logs

Versions of the npm CLI prior to 6.14.6 are vulnerable to an information exposure vulnerability through log files. The CLI supports URLs like `<protocol>://[<user>[:<password>]@]<hostname>[:<port>][:][/]<path>`. The password value is not redacted and is printed to stdout and also to any generated log files.

CVE-2019-16777low · fixedCVSS 3.1

npm Vulnerable to Global node_modules Binary Overwrite

Versions of the npm CLI prior to 6.13.4 are vulnerable to a Global node_modules Binary Overwrite. It fails to prevent existing globally-installed binaries to be overwritten by other package installations. For example, if a package was installed globally and created a `serve` binary, any subsequent installs of packages that also create a `serve` binary would overwrite the first binary. This will not overwrite system binaries but only binaries put into the global node_modules directory. This b

Sthan MCP Server

MCP server for sthan.io — give your AI assistant the ability to verify, parse, autocomplete, and geocode US addresses, and look up IP geolocation. Works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and any MCP-compatible client.

8 tools · TypeScript · stdio transport · Free tier, no credit card required.

Why use it

Real US postal data — addresses are verified against authoritative postal records, not heuristics. Returns delivery point validation (DPV), ZIP+4, residential/commercial flag.
Sub-100ms autocomplete — typeahead-grade response times for address, city, and ZIP suggestions.
Strong geocoding — forward geocoding returns accuracy classification (rooftop / interpolated / centroid / approximate) plus a confidence score, so your AI knows when to trust the result.
IPv4 + IPv6 geolocation — country, region, city, coordinates, timezone, postal code.
Free tier with no credit card — get a key in under a minute at sthan.io/dashboard.

Tools

Tool	What it does
`sthan_verify_address`	Verify a US address is real and deliverable. Returns standardized format, ZIP+4, DPV, residential/commercial.
`sthan_parse_address`	Parse freeform US address text into structured components (street number, name, type, direction, unit, city, state, zip).
`sthan_autocomplete_address`	Suggest complete US addresses from partial input. Sub-100ms.
`sthan_autocomplete_city`	Suggest US cities from partial input, with state code.
`sthan_autocomplete_zipcode`	Suggest US ZIP codes from partial input.
`sthan_geocode`	US address → latitude/longitude with accuracy + confidence.
`sthan_reverse_geocode`	Latitude/longitude → nearest US street address with distance in meters.
`sthan_ip_geolocation`	IPv4 or IPv6 → country, region, city, coordinates, timezone, postal code.

Quick start

1. Get a free API key

2. Add to your MCP client

Claude Desktop / Claude Code (~/.claude/mcp.json or project .claude/mcp.json):

{
  "mcpServers": {
    "sthan": {
      "command": "npx",
      "args": ["-y", "@sthan/mcp-server"],
      "env": { "STHAN_API_KEY": "sthan_test_your_key_here" }
    }
  }
}

Cursor (.cursor/mcp.json):

{
  "mcpServers": {
    "sthan": {
      "command": "npx",
      "args": ["-y", "@sthan/mcp-server"],
      "env": { "STHAN_API_KEY": "sthan_test_your_key_here" }
    }
  }
}

VS Code (settings.json):

{
  "mcp.servers": {
    "sthan": {
      "command": "npx",
      "args": ["-y", "@sthan/mcp-server"],
      "env": { "STHAN_API_KEY": "sthan_test_your_key_here" }
    }
  }
}

Example prompts

Once configured, just ask your AI assistant naturally:

"Is 123 Main St, New York, NY 10001 a real, deliverable address?"
"Parse this address: apt 2b 500 broadway new york ny"
"What are the coordinates of 1600 Pennsylvania Ave, Washington DC?"
"What's the nearest address to 40.7128, -74.0060?"
"Where is IP 8.8.8.8 located?"
"Suggest US cities starting with 'San Fr'."

Environment variables

Variable	Required	Description
`STHAN_API_KEY`	Yes	Your sthan.io API key (`sthan_test_` for development, `sthan_live_` for production)
`STHAN_API_URL`	No	Override base URL (default: `https://api.sthan.io`)
