Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

File ships in the package but is absent from the source [пакет] bin/cli.js:1, [пакет] bin/mcp.js:1

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Endpoint below is the one we actually reach during checks — not the one copied from a README. Last verified 8 min ago.

run in your terminal

This one needs environment variables set before it will start: A2A_API_KEY (A2A TrustGate API key (a2a_...). Optional: without a key the server starts and can guide signup; most tools require a key to call the firewall.), A2A_URL (Base URL of the A2A TrustGate API. Defaults to https://a2ainfrastructure.com.). The author declared them in the registry entry; get the values from the project itself.

A2a Trustgate — questions

Answers built from our own checks of this server.

Is A2a Trustgate working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 92 checks got a reply (0.0%), average response time 182 ms. The bar chart above shows every period we have measured.
The registry lists A2a Trustgate as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect A2a Trustgate?
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 is a remote server, so there is nothing to install — the client connects to the address.
Does A2a Trustgate need an API key?
No. A2a Trustgate completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. This is what we observed, not what the docs claim.
How many people use A2a Trustgate?
The npm package a2a-trustgate was installed 92 times in the last week. Week over week that is -83%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is A2a Trustgate open source?
We cannot say either way: 0 stars on GitHub and 1 open issue, but we could not determine the licence, and without one the code is not open source by default.
