A2a Bridge — questions

Answers built from our own checks of this server.

Why is there no uptime for A2a Bridge?
A2a Bridge 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 a2a-bridge-mcp was installed 29 times last week.
How do I connect A2a Bridge?
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 a2a-bridge-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use A2a Bridge?
The npm package a2a-bridge-mcp was installed 29 times in the last week. Week over week that is -55%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is A2a Bridge open source?
Yes — it is published under the MIT licence, written in JavaScript and 1 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.
