Typical Workflow

# In Claude Code, after adding the MCP server to settings.json:

1. purple_login       → authenticate
2. purple_analyze_repo → inspect current repo
3. purple_init_project → create project + link repo + import instructions
4. purple_list_projects → confirm project created
5. purple_sync_instructions → keep instructions in sync as CLAUDE.md evolves

Credential Storage

JWT tokens are stored in ~/.purple-codens/credentials.json with 0600 permissions (owner read/write only). Tokens are keyed by api_url so multiple Purple Codens instances are supported.

On 401 responses, credentials are automatically cleared and an AuthenticationError is raised prompting re-login.

Development

cd purple-codens/purple-codens-mcp

# Install in editable mode with dev dependencies
pip install -e ".[dev]"

# Run tests
