- 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
Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below
Plugin Name

- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
Node.js (v16 or later)
npm or yarn
npm install -g @thirdstrandstudio/mcp-tool-chainer
npm install
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:
{
"mcpServers": {
"mcp_tool_chainer": {
"command": "npx",
"args": ["-y", "@thirdstrandstudio/mcp-tool-chainer", "claude_desktop_config.json or mcp.json"],
"env": {}
}
}
}
{
"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.
This server implements the following MCP tools:
1. mcp_chain - Chain together multiple MCP servers
2. chainable_tools - Discover tools from all MCP servers so the mcp_chain tool can be used
3. discover_tools - Rediscover tools from all MCP servers
