Orchestrate your MCP servers — combine tools into reusable stacks, track execution history, and discover patterns.

curl -fsSL https://stackmcp.io/install.sh | sh
stackmcp init
stackmcp daemon start
stackmcp stacks

What it does

StackMCP runs a local daemon that connects to your MCP servers and gives you a unified CLI and API on top of them:

• Execute tools — call any tool from any MCP server through one endpoint
• Run stacks — chain tools into reusable workflows (fetch-to-obsidian, youtube-to-obsidian, etc.)
• Track history — every tool call and stack execution is recorded
• Discover patterns — the recommendations engine surfaces repeated sequences

Quickstart

# 1. Interactive setup — picks MCP servers to enable
stackmcp init

# 2. Start the daemon (auto-starts when you run any command)
stackmcp daemon start

# 3. List available stacks
stackmcp stacks

# 4. Run a stack
stackmcp run fetch-url --url "https://example.com"
stackmcp run fetch-to-obsidian --url "https://serpapi.com/blog/the-state-of-mcp"

Example stacks

| Stack | What it does | |---|---| | fetch-url | Fetch any URL and get the content | | fetch-to-obsidian | Fetch a URL and save to Obsidian | | youtube-transcript | Get transcript of any YouTube video | | youtube-to-obsidian | Transcribe video and save as note | | deepseek-chat | Chat with DeepSeek AI | | github-search-repos | Search GitHub repositories | | calendar-to-obsidian | Log today's events to Obsidian | | puppeteer-screenshot | Screenshot a webpage |

CLI

stackmcp stacks              List stacks
stackmcp run <id> --key val  Execute a stack
stackmcp history             Recent executions
stackmcp recommendations     Repeated pattern insights
stackmcp init                Interactive server setup
stackmcp daemon start|stop   Manage the daemon

How it works

   CLI ──HTTP──▶  Daemon (port 3001)
                    │
                    ├── Filesystem MCP
                    ├── Fetch MCP
                    ├── GitHub MCP
                    ├── Obsidian MCP
                    ├── YouTube MCP
                    └── ... (any MCP server)

The daemon starts all configured MCP servers, aggregates their tools, and exposes a REST API. Stacks define multi-step workflows where tool outputs flow to downstream tools automatically.

Requirements

• Node.js 18+
• An MCP server to connect (or use the built-in Fetch, Filesystem servers)

Development

npm install
npm run daemon           # Start the daemon
node bin/stackmcp stacks # Run CLI commands
