SureCheck MCP server: phone number validation and email validation tools for AI agents (0.1.1)

Phone checks return numbering-plan metadata; email checks are syntax/DNS only. Local stdio MCP server; Python 3.8+. No third-party runtime dependencies.

Download the wheel from the install page, then: python3 -m venv .venv .venv/bin/python -m pip install --no-index ./surecheck_mcp-0.1.1-py3-none-any.whl

Windows uses .venv\Scripts\python.exe and .venv\Scripts\surecheck-mcp.exe. Register the absolute path to .venv/bin/surecheck-mcp (Windows: .venv\Scripts\surecheck-mcp.exe) as the client command, with SURECHECK_API_KEY in its environment. No args required. Default SURECHECK_BASE_URL: https://surecheck-live-040.onrender.com

Alternatively open surecheck-mcp-0.1.1.mcpb in an MCPB-capable client and enter the API key in its secure settings. Python must be installed as python3 on macOS/Linux or python on Windows. Bundle is unsigned. Desktop GUI install has not been tested on macOS/Windows; manifest validation and extracted-bundle subprocess launch have been tested on Linux.

Supported transport: stdio only. No remote MCP endpoint, SSE, Streamable HTTP, OAuth, PyPI or npm publication. Protocol negotiation: 2024-11-05, 2025-03-26, 2025-06-18. Tools: check_phone(phone_number, country_code?), check_email(email). Results preserve null/unknown/error states. Phone checks are numbering-plan metadata only, not live carrier, HLR, reachability or ownership. Email checks are syntax/DNS only, not mailbox, catch-all or delivery verification. API keys are invitation-only. Current free beta: 100 checks/key; billing disabled. Host can sleep; a first request can time out. Retry after it wakes. The local wrapper stores no inputs or keys. It transmits the key and requested phone/email to SureCheck over HTTPS. DNS checks send the domain to DNS infrastructure. The host/client can keep logs according to their own settings; do not submit sensitive personal data without permission. Inputs are not saved to the API application database or access logs; account/key hashes and usage accounting are stored. Use synthetic data for demos. This release fixes the suspended default host in 0.1.0 and adds install packaging. The API deployment and earlier reviewed archives are unchanged.

Container (stdio)

A Dockerfile is included for clients that can run local stdio containers:

docker build -t surecheck-mcp .
docker run --rm -i -e SURECHECK_API_KEY surecheck-mcp

Set SURECHECK_API_KEY in the calling environment before running. Do not put the key in the Dockerfile or image. The container runs as an unprivileged user. Container build and execution are not yet verified. Including a Dockerfile does not establish compatibility with Glama's deployment service. No remote endpoint or HTTP transport is provided by this container.

Tests

python3 -m unittest discover -s tests -v

The offline suite checks malformed input recovery, argument checks, protocol negotiation, HTTPS-only configuration, blocked redirects and error handling. API responses are mocked. The suite does not verify live paid provisioning.

Shareable, User-Owned Context BackendPeople, applications, and agents read, write, and coordinate together in one context lake. Reach it over MCP, a CLI, a Python SDK, or REST.fulcradynamics.comAd
