codens-mcp 0.7.3

Unified MCP server for Codens family — Red (auto-fix), Blue (QA), Green (PRD), Auth, Purple (orchestration). All-in-one, no external purple-codens-mcp dependency.

codens-mcp

Unified MCP server for the Codens family — lets Claude Code and other AI agents operate all Codens services through a single package.

Includes all 16 Purple tools (re-exported from purple-codens-mcp) plus new tools for Red (auto-fix), Blue (QA), Green (PRD), and Auth Codens.

📖 Full agent reference: help.codens.ai (JA) / help.codens.ai/en (EN). The help page is the canonical, machine-readable reference for using Codens from any AI agent — covers Quick Start, Device Code Flow login, four practical use cases, all 30 tools, the error envelope, pricing, and troubleshooting. AI crawlers can ingest llms.txt or the full plain-text dump at llms-full.txt.

Installation

pip install codens-mcp

Quick Start (Claude Code)

1. Install

pip install codens-mcp

2. Register the MCP server

Add to your .claude/settings.json:

{
  "mcpServers": {
    "codens": {
      "command": "codens-mcp",
      "args": []
    }
  }
}

Running codens-mcp with no arguments starts the MCP server (default serve subcommand) — same behavior as before.

3. Log in (once, via Device Code Flow)

codens-mcp login

The CLI prints a verification URL and a short user code:

============================================================
  Device Authorization Required
============================================================

  1. Open this URL on any device:
     https://auth.codens.ai/device

  2. Enter this code when prompted:
     ABCD-1234

  Waiting for authorization (expires in 15 minutes)...
============================================================

Open the URL on any browser, paste the code, and approve. The CLI detects the approval, fetches your JWT, and stores it at ~/.purple-codens/credentials.json (mode 0600). The token is accepted by all Codens family backends (Red / Blue / Green / Purple / Auth), so subsequent tool calls require no further login.

# Verify
codens-mcp whoami
# → Email: [e-mail]
#   User ID: ...
#   Organization: ...

Use --auth-url / --api-url to point the login at non-default environments (e.g. --auth-url https://api.dev.auth.codens.ai).

Inside Claude Code you can also call the MCP purple_login tool instead — both flows produce the same credential file.

status = purple_get_run_status(api_url=URL, organization_id=ORG, run_id=RUN)
