Common questions

Is Byteplant MCP safe?

It passed 2 of 2 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: EV_TOKEN, AV_TOKEN, PV_TOKEN

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 21 days ago, and the latest version (1.1.1) reached the registry 24 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv), MCPB on your computer.

What can I use instead?

Byteplant MCP Server

Validate email addresses, phone numbers and postal addresses from any MCP client,

with unparalleled precision in 240+ countries worldwide.

Installation · Tools · Credentials · Usage · Compatibility · Resources


This is an MCP server that connects AI assistants such as Claude, Cursor and VS Code to the Byteplant validation APIs. Ask your assistant to check an email address, phone number or postal address, and it calls the matching Byteplant tool and reads back the result.

The server runs locally on your computer and talks to your MCP client over stdio.

Installation

The easiest way to run the server is with uv. uvx downloads the package and a suitable Python version automatically, so there is nothing else to install.

Add the server to your MCP client with one of the configurations below, and replace the placeholders with your API keys. You only need the keys for the services you use.

Claude Desktop
  1. In Claude Desktop, go to Settings → Developer → Edit Config. This opens claude_desktop_config.json:
  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
  • Windows: %APPDATA%\Claude\claude_desktop_config.json
  1. Add the Byteplant server:
   {

"mcpServers": { "byteplant": { "command": "uvx", "args": ["byteplant-mcp@latest"], "env": { "EV_TOKEN": " ", "PV_TOKEN": " ", "AV_TOKEN": " " } } } }

  1. Restart Claude Desktop.
Claude Code
claude mcp add \

--env EV_TOKEN= \ --env PV_TOKEN= \ --env AV_TOKEN= \ --transport stdio byteplant -- uvx byteplant-mcp@latest

Cursor

Add the same mcpServers entry as for Claude Desktop to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (one project).

VS Code

Add the server to .vscode/mcp.json in your project:

{

"servers": { "byteplant": { "type": "stdio", "command": "uvx", "args": ["byteplant-mcp@latest"], "env": { "EV_TOKEN": " ", "PV_TOKEN": " ", "AV_TOKEN": " " } } } }

Using pip instead of uv
pip install byteplant-mcp

This installs a byteplant-mcp command. Use its full path as the command, because desktop apps often don't see your shell's PATH (find it with which byteplant-mcp on macOS/Linux or where byteplant-mcp on Windows):

"command": "/full/path/to/byteplant-mcp"

Alternatively, run the module with the Python installation you installed it into:

"command": "/path/to/python",

"args": ["-m", "byteplant_mcp"]

Tools

ToolWhat it does
validate_emailChecks whether an email address is deliverable and detects freemail providers
validate_phoneValidates a phone number and returns its line type, carrier codes, location and formats
validate_addressValidates and standardizes a postal address, with optional geocoding

Credentials

Each tool uses its own API key, passed to the server as an environment variable. Sign up for the service you need to get one:

Environment variableUsed byGet an API key
EV_TOKENvalidate_emailEmail Validator
PV_TOKENvalidate_phonePhone Validator
AV_TOKENvalidate_addressAddress Validator

You can manage your keys in your Byteplant account. If a key is missing, the matching tool tells the assistant which variable to set instead of calling the API.

Usage

Just ask your assistant in plain language, for example:

  • *"Is support@byteplant.com a valid email address?"*
  • *"Check whether +49 9874 322466 is a mobile or a landline number."*
  • *"Validate this address and give me the standardized version: Heilsbronner Str. 4, 91564 Neuendettelsau, Germany."*

The assistant fills in the tool parameters below. Every tool also has a timeout parameter, which sets how long the API may take to respond: 5–300 seconds, 10 by default.
