MCP Config During Use

---

🚀 Features

🔄 Multiple Transport Strategies

• SSE (Server-Sent Events): Real-time bidirectional communication
• Streamable HTTP: HTTP-based streaming with session management
• Auto Detection: Automatically detects server-supported transport protocols

🔧 Advanced Capabilities

• ✅ Runtime Configuration: Configure MCP servers during each call
• ✅ Transport Auto-Detection: Smart protocol detection based on server capabilities
• ✅ HTTP Redirect Support: Seamless redirect handling
• ✅ Session Management: Persistent sessions for Streamable HTTP
• ✅ Flexible Headers: Custom HTTP headers for authentication
• ✅ Timeout Control: Configurable timeout parameters

🛠 Tool Arsenal

📖 Usage Guide

🔍 List MCP Tools

Discover all available tools on an MCP server:

Parameters:

• server_url (required): MCP server endpoint URL
• headers (optional): HTTP headers in JSON format
• timeout (optional): HTTP request timeout (seconds)
• sse_read_timeout (optional): SSE read timeout (seconds)

Example:

{
  "server_url": "http://127.0.0.1:8000/sse",
  "headers": "{\"Authorization\":\"Bearer your_token\"}",
  "timeout": 60,
  "sse_read_timeout": 300
}

⚡ Call MCP Tool

Execute a specific tool on an MCP server:

Parameters:

• server_url (required): MCP server endpoint URL
• headers (optional): HTTP headers in JSON format
• timeout (optional): HTTP request timeout (seconds)
• sse_read_timeout (optional): SSE read timeout (seconds)
• tool_name (required): Name of the tool to execute
• arguments (required): Tool arguments in JSON format

Example:

{
  "server_url": "http://127.0.0.1:8000/sse",
  "headers": "{\"Authorization\":\"Bearer your_token\"}",
  "timeout": 60,
  "sse_read_timeout": 300,
  "tool_name": "example_tool",
  "arguments": "{\"param1\":\"value1\",\"param2\":123}"
}

⚠️ Important Notes

Transport Configuration

• The plugin automatically detects server-supported transport protocols
• SSE is preferred for real-time communication
• Streamable HTTP is used as fallback or for specific requirements

JSON Parameter Handling

• All JSON objects in headers and arguments must be string-encoded
• Ensure proper double-quote escaping in JSON strings

Timeout Considerations

• Adjust timeout for connection establishment
• Configure sse_read_timeout for long-running operations
• Consider network latency in timeout settings

Session Management

• Streamable HTTP automatically manages session IDs
• Sessions are maintained across multiple requests
• Session cleanup is handled automatically
