Using Siren MCP with Other Clients

The Siren MCP server is compatible with any client that supports the Model Context Protocol standard. Here are configuration examples for popular MCP-compatible platforms:

​
5ire Desktop

Configure in 5ire’s MCP settings: 
{
  "servers": {
    "siren": {
      "command": "npx",
      "args": ["-y", "@trysiren/mcp", "--tools=all", "--api-key=YOUR_SIREN_API_KEY"]
    }
  }
}

​
FLUJO

Add to FLUJO’s workflow configuration: 
{
  "mcp_servers": {
    "siren": {
      "command": "npx -y @trysiren/mcp --tools=all --api-key=YOUR_SIREN_API_KEY"
    }
  }
}

​
Zed Editor

Configure in Zed’s assistant settings: 
{
  "assistant": {
    "mcp_servers": {
      "siren": {
        "command": "npx",
        "args": ["-y", "@trysiren/mcp", "--tools=all", "--api-key=YOUR_SIREN_API_KEY"]
      }
    }
  }
}
    func=lambda x: siren_mcp("messaging.send", **x),
    description="Send messages via Siren"
)

# Initialize the agent
llm = ChatOpenAI(temperature=0)
tools = [siren_tool]
agent = initialize_agent(tools, llm, agent=AgentType.STRUCTURED_CHAT_ZERO_SHOT_REACT_DESCRIPTION, verbose=True)

# Use the agent
agent.run("Send a test email to test@example.com")

​
3. Custom Implementation

Here’s a basic example of how to implement an MCP client in Python: 
import requests
import json

class SirenMCPClient:
    def __init__(self, api_key: str, base_url: str = "https://api.trysiren.io/v1/mcp"):
        self.base_url = base_url
        self.headers = {
            "Authorization": f"Bearer {api_key}",
            "Content-Type": "application/json"
        }
    
    def call_tool(self, tool_name: str, **params):
        response = requests.post(
            f"{self.base_url}/tools/{tool_name}",
            headers=self.headers,
            json=params
        )
        response.raise_for_status()
        return response.json()

# Example usage
client = SirenMCPClient(api_key="YOUR_SIREN_API_KEY")
result = client.call_tool(
    "messaging.send",
    channel="email",
    to="user@example.com",
    subject="Hello",
    body="This is a test message"
)
print(result)

​
Authentication

Siren MCP uses API key authentication. Include your API key in the Authorization header: 
Authorization: Bearer YOUR_SIREN_API_KEY

​
Rate Limiting

  • Default rate limit: 60 requests per minute
  • Response headers include rate limit information:
    • X-RateLimit-Limit: Maximum requests allowed
    • X-RateLimit-Remaining: Remaining requests in the window
    • X-RateLimit-Reset: Time when the limit resets (UTC timestamp)

​
Error Handling

Handle these common HTTP status codes:
  • 200 OK: Request successful
  • 400 Bad Request: Invalid request parameters
  • 401 Unauthorized: Invalid or missing API key
  • 403 Forbidden: Insufficient permissions
  • 404 Not Found: Resource not found
  • 429 Too Many Requests: Rate limit exceeded
  • 500 Internal Server Error: Server error

​
Best Practices

  1. Error Handling: Implement retry logic for transient failures
  2. Timeouts: Set appropriate timeouts for API calls
  3. Logging: Log all API interactions for debugging
  4. Security: Never expose API keys in client-side code
  5. Monitoring: Track API usage and error rates
