What your AI can do with a4sx sessions
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “search_sessions”: Search vetted, published coding-agent sessions on a4sx (reviewed marketplace listings), or your own saved sessions with scope=library. Retur.”
“Use “get_session_summary”: Describe one session before using it: what it did, outline, price, and whether you already have access. source=marketplace (default) or libr.”
“Use “acquire_session”: Add a marketplace session you are entitled to (free, bought, or granted) to your private library. Never buys anything: for a paid listing it.”
“Use “fetch_session_context”: Load a session from your library (saved, or added with acquire_session) as starting context for this conversation, sized to max_tokens.”
How secure is the a4sx sessions MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how a4sx sessions holds up.
Official endpoint
Operated by a4sx sessions (session-exchange.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 a4sx sessions adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

https://session-exchange.com/mcpQuestions, answered
