codex_cancel
Kill a running async task (preserves worktree for inspection)
How to use it
Project documentation lists codex_cancel for the Codex MCP Swarm MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.
