Flowise MCP Server

An MCP (Model Context Protocol) server that enables AI agents to interact with Flowise instances. Works with Claude Desktop, VS Code GitHub Copilot, Cursor, and other MCP-compatible clients.

Features

• Flow Management: List, create, update, and delete chatflows and agentflows
• Predictions: Send messages to flows and receive responses
• Flow Analysis: Analyze configurations with improvement suggestions
• Assistants: List and inspect Flowise assistants
• Document Stores: Manage document stores for RAG
• Vector Operations: Upsert vectors and query vector stores
• Chat History: Retrieve and delete conversation history
• Variables & Tools: Manage global variables and tools

Requirements

• Python 3.10+ or uv package manager
• A running Flowise instance with API access

Installation

Option A: Using pip

pip install flowise-mcp

Option B: Using uv (recommended)

# Install uv first if you don't have it
# Windows (PowerShell)
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

# macOS/Linux
curl -LsSf https://astral.sh/uv/install.sh | sh

Then configure your AI client to use uvx flowise-mcp (see below).

Configuration

Environment Variables

Variable	Description	Required
FLOWISE_BASE_URL	Your Flowise instance URL	Yes
FLOWISE_API_KEY	API key for authentication	Yes
FLOWISE_TIMEOUT	Request timeout in seconds (default: 60)	No

Getting your Flowise API Key

1. Open your Flowise instance
2. Go to Settings > API Keys
3. Create a new API key or copy an existing one

Setup by Client

VS Code (GitHub Copilot)

Requires VS Code 1.99+ with GitHub Copilot.

Add to .vscode/mcp.json in your project or to your User Settings (JSON):

{
  "servers": {
    "flowise": {
      "command": "uvx",
      "args": ["flowise-mcp"],
      "env": {
        "FLOWISE_BASE_URL": "https://your-flowise-instance.com",
        "FLOWISE_API_KEY": "your-api-key"
      }
    }
  }
}

Restart VS Code after adding the configuration.

• Windows: %APPDATA%\Claude\claude_desktop_config.json
• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "flowise": {
      "command": "uvx",
      "args": ["flowise-mcp"],
