Unmeasured means there is not enough evidence to decide. How these checks work
Start using a4sx sessions
Choose your client, copy the configuration, then enable the server in your client’s MCP settings.
Run this command in your terminal, then restart Claude Code.
Claude Code
claude mcp add --transport http a4sx-sessions https://session-exchange.com/mcpCapabilities
Add a marketplace session you are entitled to (free, bought, or granted) to your private library. Never buys anything: for a paid listing it returns status=payment_required with the price and the listing URL.
DiscoveredLoad a session from your library (saved, or added with acquire_session) as starting context for this conversation, sized to max_tokens.
DiscoveredStatus of a purchase you requested: pending, completed (with acquired_copy_id to load with fetch_session_context), declined or expired.
DiscoveredDescribe one session before using it: what it did, outline, price, and whether you already have access. source=marketplace (default) or library.
DiscoveredSave a session transcript (JSONL), or markdown you composed (format=markdown), to your private a4sx library. The server only rewrites text that matches secret and personal-data patterns (such as tokens, private keys, emails, IP addresses and home-directory user names). It removes no record or field: a raw Claude Code transcript keeps the user's CLAUDE.md and session context (attachment records), file-history snapshot records (absolute file paths), other non-conversation records (such as pr-link), tool-output copies (toolUseResult), and cwd, gitBranch and version on every line; the reply counts them (except version) in unprepared_carriers. Prepare first. Route A, safer when it is enough: compose the decisions, constraints, state and files worth carrying as markdown and send format=markdown. Route B (Claude Code transcripts; other formats: route A), on a copy, never the original transcript: keep only user, assistant and summary records, re-pointing each parentUuid to the nearest kept ancestor (or null); delete cwd, gitBranch, version and toolUseResult; list the hostnames, KEY=value secrets and client or employer names left (show the user counts, not values), and replace the ones the user approves, literally, in decoded strings and object keys. Either way, get the user's explicit yes before sending. Private: it is never listed publicly by this tool.
DiscoveredStart buying a paid marketplace listing for the account holder to confirm. Nothing is charged and you never pay: it returns a verify_url and a user_code to give to the account holder, who checks the code, confirms and pays. Then poll get_purchase_request.
DiscoveredSearch vetted, published coding-agent sessions on a4sx (reviewed marketplace listings), or your own saved sessions with scope=library. Returns ids to use with the other tools.
