Optional settings from the registry entry, left out of the block above: SONAR_API_BASE (API base URL. Only change it for a staging or self-hosted SONAR), SONAR_API_TIMEOUT (Per-request timeout in seconds).

SONAR: KYB due diligence — questions

Answers built from our own checks of this server.

Why is there no uptime for SONAR: KYB due diligence?

SONAR: KYB due diligence runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package getsonar-mcp was installed 194 times last week.

How do I connect SONAR: KYB due diligence?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls getsonar-mcp straight from pypi; nothing to host, nothing to sign up for.

How many people use SONAR: KYB due diligence?

The pypi package getsonar-mcp was installed 194 times in the last week. Week over week that is -67%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is SONAR: KYB due diligence open source?

Yes — it is published under the MIT licence, written in Python and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
