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 3.0 beta ships an MCP server so AI agents can work against the wiki directly.
Wiki.js 3.0 is still a beta not meant for production, but beta.705 adds a built-in MCP server, refined personal access token scopes, page lifecycle rules with page ownership, a feedback board where reviewers manage ideas, and link completion in the markdown editor. Recent betas added live notes, math, access tokens, SCIM and Excalidraw collaboration.

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 3.0 beta ships an MCP server so AI agents can work against the wiki directly.
◆ Current state
Wiki.js 3.0 is still a beta not meant for production, but beta.705 adds a built-in MCP server, refined personal access token scopes, page lifecycle rules with page ownership, a feedback board where reviewers manage ideas, and link completion in the markdown editor. Recent betas added live notes, math, access tokens, SCIM and Excalidraw collaboration.
◆ Where it's heading
Each beta adds a piece that larger teams need: SSO and SCIM, governance through ownership and lifecycle rules, and now machine access through MCP and scoped tokens. 3.0 is becoming an AI-accessible knowledge base with enterprise controls rather than a straight successor to 2.x.
◆ Prediction
Expect MCP tools to be tied to the new PAT scopes and page rules, and the beta cadence to keep adding governance features before a release candidate.
