# Catch up on Slack. Get back to work. Source: https://corespeed.io/integrations/slack Connect Slack to Claude Code, Codex, Cursor or any MCP agent through CoreSpeed. Your agent searches the channels your account can see, reads a thread, and hands back the decisions, the open questions and a next-step plan. It signs in with your own Slack account, never reads past your workspace permissions, and posting is a separate call. ## Set up an agent Give your agent this line: `set up https://corespeed.io/SKILL.md (read it raw, e.g. with curl)` It fetches the skill at https://corespeed.io/SKILL.md, adds the CoreSpeed MCP server, signs you in (or up), and keeps the skill for next time. Connect Slack after setup. Access follows the connected account and its permissions. Create an account: https://app.corespeed.io/sign-up ## A good discussion. A clear next step Have your agent turn a thread into a recap and a proposed plan. Unresolved decisions stay visible instead of guessed. You ask your agent: "Read the launch discussion in Slack. Summarize the decisions and draft a next-step plan. Flag anything the team has not agreed yet." It calls CoreSpeed: - `slack__search_messages`: ok, 388 ms - `slack__conversations_replies`: ok, 452 ms It reads from: Slack. ### Discussion recap: Here is where we landed. Start with the customer use case. The launch date and the first test’s success measure still need a decision. **Suggested next steps** - Draft focused messaging. - Prepare a landing page around the chosen use case. **Do not assume** - A launch date has not been agreed. - The team has not picked a success measure. _Illustrative discussion · Nothing posted to Slack_ All connectors: https://corespeed.io/docs/connectors ## Keep the decisions.

Bring your work One CoreSpeed account, across compatible agents. 1. **Set up CoreSpeed**: Give your agent the setup line. It adds CoreSpeed and signs you in. 2. **Connect Slack**: Authorize the account and the content you need. 3. **Start with one task**: Ask for a summary, a brief, or a draft. Review the answer.

No. It brings Slack tools into an agent such as Claude Code, Codex, or Cursor. It is not a hosted Slack chatbot. ### Can it read every private channel? No. It sees only what the connected Slack account can see, within the scopes you grant. CoreSpeed does not bypass workspace permissions. ### Do I have to switch agents? No. CoreSpeed adds tools to the agent you already use: Claude Code, Codex, Cursor, or another MCP client. Each one signs in once. ### Can my agent access every account in our organization? No. Access follows your CoreSpeed identity, each connection's visibility, and the app's own permissions. Personal connections stay private. ### Does this work without connecting an account? No. Connect the app's account first; your CoreSpeed workspace shows what each app needs. The examples on this page use fictional data.
