This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal
claude mcp add attest-mcp -- npx -y @spazio-genesi/attest-mcp
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "attest-mcp": {

        "-y",

}

This one needs environment variables set before it will start: IMGAUTH_API_KEY (API key credential for the attestation service (optional — bypasses the interactive device-flow authorization).), IMGAUTH_BASE_URL (Override the API base URL, e.g. for local development against a `wrangler dev` instance.), IMGAUTH_CERT_PAGE_BASE (Override the base URL used to build permanent certificate-verification page links.). The author declared them in the registry entry; get the values from the project itself.

Attest MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Attest MCP?
Attest 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 @spazio-genesi/attest-mcp was installed 61 times last week.
How do I connect Attest 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 @spazio-genesi/attest-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use Attest MCP?
The npm package @spazio-genesi/attest-mcp was installed 61 times in the last week. Week over week that is +30%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Attest MCP open source?
Yes — it is published under the MIT licence, written in JavaScript 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.
