Put your own values in place of <CONFLUENCE_URL> (Base URL of the Confluence Data Center instance), <CONFLUENCE_USER_TOKEN> (Personal Access Token for standard operations). The author’s registry entry marks them as required.

Optional settings from the registry entry, left out of the block above: CONFLUENCE_ADMIN_TOKEN (Personal Access Token for elevated/admin operations (optional)).

Castor MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Castor MCP?
Castor MCP 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 npm package castor-mcp was installed 68 times last week.
How do I connect Castor MCP?
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 castor-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use Castor MCP?
The npm package castor-mcp was installed 68 times in the last week. Week over week that is +110%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
