**Command-line interface for interacting with MCP servers - list tools, call tools, and export schemas.**
## Overview
`turbomcp-cli` provides essential tools for working with MCP (Model Context Protocol) servers. Connect to any MCP server via HTTP or WebSocket to explore available tools, execute them, and export their schemas.
## Features
- **🔧 Tool Management** - List and call tools on running MCP servers
- **📋 Schema Export** - Export tool schemas for documentation and validation
- **🌐 Multi-Transport** - Support for HTTP and WebSocket connections
- **📊 JSON Output** - Machine-readable output for automation
## Installation
### From Crates.io
```bash
# Install latest stable version
cargo install turbomcp-cli
# Install specific version
cargo install turbomcp-cli --version 1.1.0
```
### From Source
```bash
git clone https://github.com/Epistates/turbomcp.git
cd turbomcp
cargo install --path crates/turbomcp-cli
```
## Usage
```bash
turbomcp-cli <COMMAND>
Commands:
tools-list List tools from a running server
tools-call Call a tool on a running server
schema-export Export tool schemas from a running server
help Print this message or the help of the given subcommand(s)
Options:
-h, --help Print help
-V, --version Print version
```
### Connection Options
All commands support these connection options:
- `--url <URL>` - Server URL for HTTP/WebSocket or command path for STDIO (default: `http://localhost:8080/mcp`)
- `--command <COMMAND>` - Command to execute for STDIO transport (overrides `--url`)
- `--auth <AUTH>` - Bearer token or API key for authentication
- `--json` - Output results in JSON format
## Commands
### `tools-list` - List Available Tools
List all tools available from an MCP server.
```bash
# List tools from HTTP server
turbomcp-cli tools-list --url http://localhost:8080/mcp
# List tools from WebSocket server
turbomcp-cli tools-list --url ws://localhost:8080/mcp
# List tools from STDIO server
turbomcp-cli tools-list --command "./target/debug/my-server"
```
**Example Output:**
```
Available Tools:
- calculator_add: Add two numbers together
- file_read: Read contents of a file
- search_web: Search the web for information
Total: 3 tools
```
### `tools-call` - Call a Tool
Execute a specific tool on the MCP server.
```bash
# Call a tool with JSON parameters (HTTP)
turbomcp-cli tools-call \
--url http://localhost:8080/mcp \
--name calculator_add \
--arguments '{"a": 5, "b": 3}'
# Call a tool via WebSocket
turbomcp-cli tools-call \
--url ws://localhost:8080/mcp \
--name file_read \
--arguments '{"path": "/etc/hosts"}'
# Call a tool via STDIO
turbomcp-cli tools-call \
--command "./target/debug/my-server" \
--name calculator_add \
--arguments '{"a": 5, "b": 3}'
```
**Example Output:**
```json
{
"result": 8,
"success": true
}
```
### `schema-export` - Export Tool Schemas
Export JSON schemas for all tools from an MCP server.
```bash
# Export schemas to stdout (HTTP)
turbomcp-cli schema-export --url http://localhost:8080/mcp
# Export schemas to file (HTTP)
turbomcp-cli schema-export \
--url http://localhost:8080/mcp \
--output schemas.json
# Export schemas from STDIO server
turbomcp-cli schema-export \
--command "./target/debug/my-server" \
--output schemas.json
```
**Example Output:**
```json
{
"tools": [
{
"name": "calculator_add",
"description": "Add two numbers together",
"inputSchema": {
"type": "object",
"properties": {
"a": {"type": "number"},
"b": {"type": "number"}
},
"required": ["a", "b"]
}
}
]
}
```
## Transport Support
The CLI supports three transport methods:
### HTTP/HTTPS
```bash
turbomcp-cli tools-list --url http://localhost:8080/mcp
turbomcp-cli tools-list --url https://api.example.com/mcp
```
### WebSocket
```bash
turbomcp-cli tools-list --url ws://localhost:8080/mcp
turbomcp-cli tools-list --url wss://api.example.com/mcp
```
### STDIO (Standard Input/Output)
```bash
# Using --command option
turbomcp-cli tools-list --command "./my-server"
turbomcp-cli tools-list --command "python server.py"
# Or specify path in --url (auto-detected)
turbomcp-cli tools-list --url "./my-server"
```
**Transport Auto-Detection:**
- URLs starting with `http://`, `https://` → HTTP transport
- URLs starting with `ws://`, `wss://` → WebSocket transport
- `--command` option or executable paths → STDIO transport
## Examples
```bash
# List tools from HTTP server
turbomcp-cli tools-list --url http://localhost:8080/mcp
# Call calculator tool via STDIO
turbomcp-cli tools-call \
--command "./target/debug/calculator-server" \
--name calculator_add \
--arguments '{"a": 10, "b": 5}'
# Export all schemas to file via WebSocket
turbomcp-cli schema-export \
--url ws://localhost:8080/mcp \
--output my-server-schemas.json
# Test STDIO server with authentication
turbomcp-cli tools-list \
--command "python my-server.py" \
--auth "bearer-token-here" \
--json
```
