This one needs environment variables set before it will start: SIGLIO_API_KEY (Your Siglio API key. Sandbox keys start with sig_sandbox_ and live keys start with sig_live_. Get one at https://esigndev.com), SIGLIO_ALLOW_LIVE (Set to true to allow a live key. Without it, live keys are refused and only sandbox keys will run. Leave unset while testing.). The author declared them in the registry entry; get the values from the project itself.

Siglio MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Siglio MCP?

Siglio 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 siglio-mcp was installed 792 times last week.

How do I connect Siglio MCP?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls siglio-mcp straight from npm; nothing to host, nothing to sign up for.

How many people use Siglio MCP?

The npm package siglio-mcp was installed 792 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
