fenix-mcp 2.2.1

Fênix Cloud MCP server implemented in Python

Fenix MCP Server
Python MCP server for Fenix Cloud API integration

Quick Start • Installation • Configuration • Structure

---

Overview

Fenix MCP connects MCP-compatible clients (Claude Code, Cursor, Windsurf, VS Code, etc.) directly to the Fenix Cloud APIs. Every tool invocation hits the live backend—no outdated snapshots or hallucinated IDs.

Available Tools:

• knowledge — Documentation CRUD, work items, modes, rules
• productivity — TODO management
• intelligence — Memories and smart operations
• user_config — User configuration documents
• initialize — Personalized setup
• health — Backend health check

Quick Start

pipx install fenix-mcp                    # Install
fenix-mcp --pat <your-token>              # Run (STDIO mode)

---

Requirements

Requirement	Version
Python	3.10+
Fenix PAT Token	Required
MCP Client	Claude Code, Cursor, Windsurf, VS Code, etc.

---

Installation

With pipx (recommended)

pipx install fenix-mcp

With pip

pip install --user fenix-mcp

Upgrade

pipx upgrade fenix-mcp
# or
pip install --upgrade fenix-mcp

Configuration

MCP Client Setup

Claude Code — ~/.claude/config.toml

[mcp_servers.fenix]
command = "fenix-mcp"
args = ["--pat", "your-token"]

Cursor — ~/.cursor/mcp.json

{
  "mcpServers": {
    "fenix": {
      "command": "fenix-mcp",
      "args": ["--pat", "your-token"],
      "disabled": false
    }
  }
}

VS Code / Windsurf — settings.json

{
  "modelContextProtocol.mcpServers": {
    "fenix": {
      "command": "fenix-mcp",
      "args": ["--pat", "your-token"]
    }
  }
}

Troubleshooting

command not found: fenix-mcp

Add scripts directory to PATH:

# macOS/Linux
export PATH="$PATH:~/.local/bin"

# Windows
# Add %APPDATA%\Python\Python311\Scripts to PATH

401 Unauthorized

1. Check --pat or FENIX_PAT_TOKEN is set correctly
2. Regenerate token in Fenix Cloud if expired

Run HTTP and STDIO simultaneously

export FENIX_TRANSPORT_MODE=both
fenix-mcp --pat <your-token>

---

Security

• Store tokens securely (keychain, pass, .env)
• Never commit secrets to git
• Revoke tokens when no longer needed
• Use pipx to isolate from global Python
