Slack vs Wiki.js: at a glance
What is Slack?
Slack now hosts any A2A agent without Slack-specific code.
Slack's developer channel is almost all agent plumbing. On 10 November Slack became an A2A (Agent2Agent) client: a team hosts its own agent, publishes an Agent Card, and Slack calls it when people talk to it, with no request URL, event handling or Slack-specific logic. This follows Slackbot skills managed through Web API methods, a Slack CLI that points coding agents to the Slack MCP server, and a new requirement that Work Objects embeds allow the slack-mcps.com frame ancestor.
What is Wiki.js?
Wiki.js 3 beta.705 ships a built-in MCP server and page ownership with lifecycle rules.
Wiki.js 3 is still marked not for production, but beta.705 adds a built-in MCP server, page ownership with lifecycle rules, a feedback board that reviewers can edit and categorize, and link completion in the markdown editor. PAT scopes get a clearer dialog, which matters now that tokens are how outside clients connect.

Slack now hosts any A2A agent without Slack-specific code.
◆ Current state
Slack's developer channel is almost all agent plumbing. On 10 November Slack became an A2A (Agent2Agent) client: a team hosts its own agent, publishes an Agent Card, and Slack calls it when people talk to it, with no request URL, event handling or Slack-specific logic. This follows Slackbot skills managed through Web API methods, a Slack CLI that points coding agents to the Slack MCP server, and a new requirement that Work Objects embeds allow the slack-mcps.com frame ancestor.
◆ Where it's heading
Slack is lowering the cost of putting outside agents in front of its users: first skills as code, then MCP pointers for coding agents, now a standard protocol in place of the Slack app model for agents. The platform is positioning itself as the place where agents built anywhere meet the people who use them.
◆ Prediction
Expect more A2A follow-ups, such as agents appearing in Slackbot or skills surfaces and richer Agent Card features, given how fast the agent releases have stacked up since October.

6.3COLLAB
Wiki.js 3 beta.705 ships a built-in MCP server and page ownership with lifecycle rules.
◆ Current state
Wiki.js 3 is still marked not for production, but beta.705 adds a built-in MCP server, page ownership with lifecycle rules, a feedback board that reviewers can edit and categorize, and link completion in the markdown editor. PAT scopes get a clearer dialog, which matters now that tokens are how outside clients connect.
◆ Where it's heading
The v3 betas have moved from editor features (live notes, math, draft recovery) toward governance and machine access: personal access tokens in beta.672, then MCP and page lifecycle rules here. The project is building the controls an organization needs before trusting a wiki to AI clients and to long-lived content.
◆ Prediction
Expect more MCP tools and PAT scope options in the next betas, and lifecycle rules tied into notifications for review and expiry.
