🛠️ Developer Integration

MCPOmni Connect is not just a CLI tool—it's also a powerful Python library that you can use to build your own backend services, custom clients, or API servers.

Build Your Own MCP Client

You can import MCPOmni Connect in your Python project to:

• Connect to one or more MCP servers
• Choose between ReAct Agent mode (autonomous tool use) or Orchestrator Agent mode (multi-step, multi-server planning)
• Manage memory, context, and tool orchestration
• Expose your own API endpoints (e.g., with FastAPI, Flask, etc.)

Example: Custom Backend with FastAPI

See examples/fast_api_iml.py for a full-featured example.

Minimal Example:

from mcpomni_connect.client import Configuration, MCPClient
from mcpomni_connect.llm import LLMConnection
from mcpomni_connect.agents.react_agent import ReactAgent
from mcpomni_connect.agents.orchestrator import OrchestratorAgent

config = Configuration()
client = MCPClient(config)
llm_connection = LLMConnection(config)

# Choose agent mode
agent = ReactAgent(...)  # or OrchestratorAgent(...)

# Use in your API endpoint
response = await agent.run(
    query="Your user query",
    sessions=client.sessions,
    llm_connection=llm_connection,
    # ...other arguments...
)

FastAPI Integration

You can easily expose your MCP client as an API using FastAPI.
See the FastAPI example for:

• Async server startup and shutdown
• Handling chat requests with different agent modes
• Streaming responses to clients

Key Features for Developers:

• Full control over agent configuration and limits
• Support for both chat and autonomous agentic modes
• Easy integration with any Python web framework

Token & Usage Management

MCPOmni Connect now provides advanced controls and visibility over your API usage and resource limits.

View API Usage Stats

Use the /api_stats command to see your current usage:

/api_stats

This will display:

• Total tokens used
• Total requests made
• Total response tokens
• Number of requests

Set Usage Limits

You can set limits to automatically stop execution when thresholds are reached:

• Total Request Limit:
  Set the maximum number of requests allowed in a session.
• Total Token Usage Limit:
  Set the maximum number of tokens that can be used.
• Tool Call Timeout:
  Set the maximum time (in seconds) a tool call can take before being terminated.
• Max Steps:
  Set the maximum number of steps the agent can take before stopping.

You can configure these in your servers_config.json under the AgentConfig section:

"AgentConfig": {
    "tool_call_timeout": 30,        // Tool call timeout in seconds
    "max_steps": 15,                // Max number of steps before termination
    "request_limit": 1000,          // Max number of requests allowed
    "total_tokens_limit": 100000    // Max number of tokens allowed
}

• When any of these limits are reached, the agent will automatically stop running and notify you.

Example Commands

# Check your current API usage and limits
/api_stats

# Set a new request limit (example)
# (This can be done by editing servers_config.json or via future CLI commands)
