Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

Tool list from our last check. Connect live to refresh it.

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 returns status=payment_required with the price and the listing URL.

idstring, required

Marketplace listing id (from search_sessions).

tenantstring

Owning workspace of a marketplace listing (from search results). Optional.

versionstring

This tool isn't marked read-only, so it may change something on the server or in an account you connected.

I understand, run it anyway

source	string
tenant	string	Owning workspace of a marketplace listing (from search results). Optional.

  },
  "additionalProperties": false

publish_session

Save 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 the transcript or compose markdown first, as GET /orient on this server without auth describes (route A, or route B steps 0-8). Private: it is never listed publicly by this tool.

Argument	Type	Description
label	string
title	string
format	string	jsonl: a transcript. markdown: content you composed (route A in GET /orient on this server without auth); stored as sent, after the same server scrub.
parent	string	Library id this session continues from (lineage).
transcript*	string	The session transcript as JSONL (Claude Code or Codex CLI format; detected automatically), or markdown you composed with format=markdown.
visibility	string	Always private. Listing publicly is a separate step in the web app.

request_purchase

Start 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.

Argument	Type	Description
id*	string	Marketplace listing id (from search_sessions).
tenant*	string	The listing's workspace (from search_sessions).
version	string	The version you expect; must be the one on sale.

Input schema (JSON)

  "type": "object",
  "required": [
    "id",
    "tenant"

search_sessions

Search 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.

read-only

Argument	Type	Description
sort	string
tags	array
limit	integer
query	string	Free-text search. Empty = browse.
scope	string	`public`: vetted marketplace listings (no sign-in needed). `library`: your own saved sessions (needs library:read).
offset	integer
harness	array	Only sessions recorded with these harnesses (claude-code, codex-cli, gemini-cli, opencode, grok-build; unknown = not identified). Only Claude Code sessions can be resumed today; the others are view & buy.
