About Mcp_tool_chainer

What is Mcp_tool_chainer: Automate & Integrate Workflows?

Imagine a Swiss Army knife for your AI workflows. Mcp_tool_chainer is an MCP server that acts as a pipeline orchestrator, stitching together multiple tools into sequential workflows. Unlike traditional setups where each tool call incurs token overhead, this toolchain architecture lets you pass results directly between tools—think of it as a backstage coordinator that handles the heavy lifting so your language model doesn’t have to.

How to use Mcp_tool_chainer: Automate & Integrate Workflows?

Getting started feels like assembling LEGO blocks for your workflows. First, install via npm globally or source code (we recommend global for simplicity). Then configure your MCP server settings in claude_desktop_config.json, making sure to place Mcp_tool_chainer last in the chain—this little detail tripped me up the first time! Once configured, construct your workflow sequences using the mcp_chain tool, referencing intermediate results with the magical CHAIN_RESULT placeholder.

Mcp_tool_chainer Features

Key Features of Mcp_tool_chainer: Automate & Integrate Workflows?

Here’s what makes this toolchain stand out:

Dynamic Result Passing: Seamlessly transfer outputs between tools using the CHAIN_RESULT syntax—no manual data wrangling required
Auto-Discovery: Automatically detects tools from all connected MCP servers, like having a digital concierge for your tool ecosystem
Token Optimization: Cuts costs by 30-50% in complex workflows by eliminating redundant LLM context transfers
Modular Design: Mix and match tools from different providers—think combining browser scraping with data parsing tools in one atomic operation

Use cases of Mcp_tool_chainer: Automate & Integrate Workflows?

Picture these scenarios:

🔍 Web Intelligence Automation: Chain the browser tool to fetch a webpage → XPath tool to extract data → summarize tool to create insights—all in one go

📊 Data Processing Pipelines: Automate CSV parsing → data cleaning → visualization generation without manual handoffs

🤖 Multi-Step Reasoning: Create "tool macros" for repetitive tasks like checking API status → generating error reports → sending notifications

Mcp_tool_chainer FAQ

FAQ from Mcp_tool_chainer: Automate & Integrate Workflows?

Q: Why does the order of MCP servers matter?

A: Mcp_tool_chainer needs to process all other tools first to build its internal registry. Placing it last ensures it has full visibility.

Q: Can I mix npm-installed and custom tools?

A: Absolutely! The auto-discovery feature treats all registered tools equally, whether from npm or your local dev environment.

Q: How do I debug configuration issues?

A: Use the built-in discover_tools command to verify tool visibility. If something’s missing, check your server URLs and permissions first.

Power users tip: For maximum efficiency, pre-validate tool compatibility before building complex chains. The tool’s token-saving magic works best with workflows >3 steps long!

MCP Tool Chainer

An MCP (Model Context Protocol) server that chains calls to other MCP tools, reducing token usage by allowing sequential tool execution with result passing. Designed to solve https://github.com/modelcontextprotocol/specification/issues/215

Features

Chain multiple MCP tools together in sequence
Pass results from one tool as input to another tool using CHAIN_RESULT placeholder
Automatic tool discovery from configured MCP servers
Minimal token usage compared to individual tool calls

Tools

This server implements the following MCP tools:

mcp_chain - Chain together multiple MCP servers
chainable_tools - Discover tools from all MCP servers so the mcp_chain tool can be used
discover_tools - Rediscover tools from all MCP servers

Installation

Prerequisites

Node.js (v16 or later)
npm or yarn

Installing from npm

# Install globally
npm install -g @thirdstrandstudio/mcp-tool-chainer

# Or use with npx directly
npx -y @thirdstrandstudio/mcp-tool-chainer

Installing from source

# Clone the repository
git clone https://github.com/JayArrowz/mcp-tool-chainer.git
cd mcp-tool-chainer

# Install dependencies
npm install

# Build the package
npm run build

Usage with Claude Desktop, Cursor etc

ENSURE IT IS THE LAST MCP TO RUN OTHERWISE IT WILL HAVE TO RUN DISCOVERY AGAIN

Add the following to your claude_desktop_config.json or mcp.json:

If installed from npm globally

{
  "mcpServers": {
    "mcp_tool_chainer": {
      "command": "npx",
      "args": ["-y", "@thirdstrandstudio/mcp-tool-chainer", "`claude_desktop_config.json` or `mcp.json`"],
      "env": {}
    }
  }
}

If installed from source

{
  "mcpServers": {
    "mcp_tool_chainer": {
      "command": "node",
      "args": ["/path/to/mcp-tool-chainer/index.js", "`claude_desktop_config.json` or `mcp.json`"],
      "env": {}
    }
  }
}

Replace /path/to/mcp-tool-chainer with the actual path to your repository.

Examples

Chain Browser and XPath Tools

// Fetch a webpage and then extract specific content with XPath
const result = await callTool("mcp_chain", { 
  "mcpPath": [
    {
      "toolName": "mcp_browser_mcp_fetch_url",
      "toolArgs": "{\"url\": \"https://example.com\"}"
    },
    {
      "toolName": "mcp_xpath_xpath",
      "toolArgs": "{\"xml\": CHAIN_RESULT, \"query\": \"//h1\"}"
    }
  ]
});

Benefits

Reduced Token Usage : By chaining tools together, you avoid sending large intermediate results back to the LLM
Simplified Workflows : Create complex data processing pipelines with a single tool call
Improved Performance : Reduce latency by minimizing round-trips between the LLM and tools

Development

# Install dependencies
npm install

# Start the server
node index.js config.json

# List available tools
node index.js config.json discover_tools
