Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
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.
You need to fill in: EV_TOKEN, AV_TOKEN, PV_TOKEN
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).

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.
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_config.json:~/Library/Application Support/Claude/claude_desktop_config.json%APPDATA%\Claude\claude_desktop_config.json {
"mcpServers": { "byteplant": { "command": "uvx", "args": ["byteplant-mcp@latest"], "env": { "EV_TOKEN": " ", "PV_TOKEN": " ", "AV_TOKEN": " " } } } }
claude mcp add \
--env EV_TOKEN= \ --env PV_TOKEN= \ --env AV_TOKEN= \ --transport stdio byteplant -- uvx byteplant-mcp@latest
Add the same mcpServers entry as for Claude Desktop to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (one project).
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": " " } } } }
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"]
| Tool | What it does |
|---|---|
validate_email | Checks whether an email address is deliverable and detects freemail providers |
validate_phone | Validates a phone number and returns its line type, carrier codes, location and formats |
validate_address | Validates and standardizes a postal address, with optional geocoding |
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 variable | Used by | Get an API key |
|---|---|---|
EV_TOKEN | validate_email | Email Validator |
PV_TOKEN | validate_phone | Phone Validator |
AV_TOKEN | validate_address | Address 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.
Just ask your assistant in plain language, for example:
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.
