Agent Fleet

v0.34.0

MCP sign-in works in both directions. Remote MCP clients such as claude.ai and ChatGPT can connect to Agent Fleet by signing in instead of pasting a token, and you can sign in to MCP servers that require OAuth from Settings so your sessions can use them. EC2 pool slots get a force-stop and more memory headroom for the host, and the Jira CLI copes with a flaky network.

New

Section titled “New”
  • Remote MCP clients connect by signing in (OAuth). claude.ai, ChatGPT, Claude Code and other MCP clients sign you in to the Console and you choose the tenant and read or write access, instead of pasting a Personal Access Token. Off by default: the operator turns it on with AF_MCP_OAUTH=1. Settings › Connections › MCP tokens lists your connected apps with their recent calls and lets you revoke them. A tenant admin can switch it off for the tenant, and a deployment administrator edits which client hosts are trusted in the Admin panel. Input a client sends to a session is marked Via MCP. (#2433, #2434, #2455, #2457, #2531, #2542, #2567)
  • Sign in to MCP servers that require OAuth. In Settings › MCP servers, choose OAuth as the authentication of a remote server and press Sign in; the connection test already tells you when a server needs it. Sessions reach the server through a relay in your workspace, so the token is never written into a CLI’s configuration. claude, copilot and cursor have been seen using it; servers distributed by the tenant cannot use OAuth yet. (#2479, #2485, #2549, #2568, #2580)
  • Force-stop a wedged EC2 pool slot. A deployment administrator can stop a slot whose ECS and SSM agents went silent with Stop (force) on the pool screen; the member’s next Start wakes the same slot. (#2449)
  • Open shell here in a folder’s context menu starts a shell session in that folder. (#2460)
  • Edit and delete Jira comments with jira issue comment edit and delete in a session. (#2477)
  • Muse Code contributor mode can be switched on in the Muse Code card of Settings › Agents. (#2535)

Improved

Section titled “Improved”
  • The MCP server forms start from a remote server with a display name and an authentication choice (none, Bearer token, custom headers or OAuth); the ID follows the name. (#2550)
  • The Jira CLI survives a flaky network. Reads are retried, a hung command times out, a timed-out issue create lists the issues it may have created, and an expired connection says so in one line. Agent instructions may now prefer an Atlassian MCP tool over the CLI. (#2476, #2532, #2538, #2539, #2543)
  • ECS-EC2: the host keeps 2 GiB of every slot and its ECS and SSM agents are protected from memory reclaim, so a busy workspace no longer takes the slot dark. An 8 GiB slot’s workspace is now capped at 6 GiB instead of 6.4 GiB. (#2451, #2452)
  • ECS-EC2: a Start stuck behind a task that cannot finish stopping is shown as blocked with the reason instead of an endless “starting”. (#2447)
  • Muse Code 1.4.12 is supported, and its new record kinds show as one-line summaries. (#2575)

Fixed

Section titled “Fixed”
  • copilot sessions did not start once copilot had updated itself to 1.0.103. Both the old and the new copilot now work. (#2576)
  • ECS-EC2: a workspace stuck in “starting” could not be stopped, and a Start after a size change timed out on a wedged slot. (#2446, #2448)
  • ECS-EC2: AF_ECS_EC2_HOST_RESERVE_MB=0 was treated as auto. It now reserves nothing. (#2503)
  • Folders you made under ~/.af-work could be deleted when the workspace started. Only folders Agent Fleet created for a session are cleaned up now. (#2454)
  • A just-finished reply could vanish for a moment before the final message appeared. (#2564)
  • opencode Terminal panes could stay disconnected after the shared server restarted. (#2432)
  • ChatGPT refused the /mcp tool list because of an invalid schema. (#2540)
  • Smaller fixes: the Preview settings entry stayed hidden after a Control Plane error, and the command palette’s selection could fall off the list. (#2317, #2504, #2554)

Upgrade notes

Section titled “Upgrade notes”
  • ECS deployments: deploy the 20-platform stack before using Stop (force), and the 40-ec2-pool stack so new slots protect their agents. Workspaces on 8 GiB slots get 0.4 GiB less memory from their next start.
  • MCP sign-in is opt-in: set AF_MCP_OAUTH=1 (with AF_MCP_ENABLED=true and an https PUBLIC_BASE_URL). Hosted clients reach /mcp from their vendors’ servers, so it has to be reachable from the internet; behind AUTH=proxy, see the operator guide for which paths bypass the gateway.
