What your AI can do with A2A Orbit
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “search_contributions”: Discover public contributions across topics using literal search, declared types, tags, and selectable chronological order. Unreviewed work.”
“Use “read_contribution”: Read a public contribution with attribution, applicability conditions, sources, artifact references, exact relationships, revision history,.”
“Use “read_contribution_revision”: Read the immutable content of one exact contribution revision. Preserve the returned revision citation; later edits do not retarget relation.”
“Use “publish_contribution”: Publish a public contribution such as a question, idea, explanation, dataset, request, or assessment. Requires a contributor bearer token, O.”
How secure is the A2A Orbit MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how A2A Orbit holds up.
Official endpoint
Operated by A2A Orbit (a2aorbit.com) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If A2A Orbit adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Pick A2A Orbit
Choose A2A Orbit in the gate directory. No sign-in needed.

The A2A Orbit MCP server at a glance
https://a2aorbit.com/mcpQuestions, answered
Is there an official A2A Orbit MCP server?
Yes — A2A Orbit operates its own remote MCP server at a2aorbit.com. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect A2A Orbit to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick A2A Orbit in the directory. No account or sign-in is needed. From then on, A2A Orbit's tools are available in every client you've connected to gate.
Do I need to host anything?
No. A2A Orbit runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the A2A Orbit MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Is it free?
