What is Tango?
Tango ships an MCP server, so AI assistants can answer from a team's captured workflows.
Tango captures browser workflows into step-by-step guides, and the Tango MCP, now live on Enterprise plans, lets teams query their Tango workspace from inside AI assistants. Before it, 2026 releases deepened the guide itself: voice narration during capture, branching, translations, video embeds, plus a September rebrand and edit-mode shortcuts.
What is Mattermost?
Mattermost v12.1 puts bots and burn-after-reading messages under the same access rules.
Mattermost v12 shipped in parts: agents limited to the requesting user's access, Cross Guard for transfers across security domains, and user, device and channel attributes in access policy. A November 9 partnership pairs v12 with Arqit's quantum-safe device trust. v12.1 on November 13 extends attribute-based access control to bot accounts and to Burn-on-Read permissions, and Desktop v6.4 fixes Boards on subpath deployments.

Tango
3.8COLLAB
Tango ships an MCP server, so AI assistants can answer from a team's captured workflows.
◆ Current state
Tango captures browser workflows into step-by-step guides, and the Tango MCP, now live on Enterprise plans, lets teams query their Tango workspace from inside AI assistants. Before it, 2026 releases deepened the guide itself: voice narration during capture, branching, translations, video embeds, plus a September rebrand and edit-mode shortcuts.
◆ Where it's heading
The MCP changes where Tango's content gets read: guides become a knowledge source for AI tools, not only pages people open. It is the first AI move in the feed since the April 2025 AI CRM Admin agent, and again gated to Enterprise, where governance and translations also landed.
◆ Prediction
The entry is short on scope, so it is unclear whether the MCP is read-only; a follow-up widening it to more plans or adding write actions such as creating guides would be the next signal.
Mattermost
6.3COLLAB
Mattermost v12.1 puts bots and burn-after-reading messages under the same access rules.
◆ Current state
Mattermost v12 shipped in parts: agents limited to the requesting user's access, Cross Guard for transfers across security domains, and user, device and channel attributes in access policy. A November 9 partnership pairs v12 with Arqit's quantum-safe device trust. v12.1 on November 13 extends attribute-based access control to bot accounts and to Burn-on-Read permissions, and Desktop v6.4 fixes Boards on subpath deployments.
◆ Where it's heading
Each release closes another gap in one policy model for who and what can see a message: people, devices, channels, and now automation accounts and ephemeral messages. The audience stays defence and regulated buyers, and point releases are filling in v12 rather than starting new lines.
◆ Prediction
Further v12.x releases likely apply the same attribute rules to more objects, such as files, plugins or AI agent actions, following the pattern of v12.1.
