MCP Authentication
OAuth Client Credentials (Claude Code 2.1.30+)
For MCP servers that don't support Dynamic Client Registration (e.g., Slack), pre-configured OAuth client credentials can be provided:
claude mcp add <server-name> --client-id <id> --client-secret <secret>
This enables delegation workflows through MCP servers that require pre-configured OAuth, expanding the range of external services available for task delegation.
Claude.ai MCP Connectors (Claude Code 2.1.46+)
As an alternative to manual OAuth setup, users can configure MCP servers directly in claude.ai at claude.ai/settings/connectors. These connectors are automatically available in Claude Code when logged in with a claude.ai account: no claude mcp add or credential management required. This provides a browser-based auth flow that may be simpler for services with complex OAuth requirements.
Worktree Isolation for File-Modifying Delegations (Claude Code 2.1.49+)
When delegating tasks that modify files to subagents, use isolation: worktree in the agent frontmatter to run each agent in a temporary git worktree. This prevents file conflicts when multiple delegated agents operate in parallel on overlapping paths. The worktree is auto-cleaned if no changes are made; preserved with commits if the agent produces changes.
