Model Context Protocol

MCP (Model Context Protocol) is a protocol for exposing tools and resources to AI agents. Read more here.

Basic MCP Usage

This example is available on GitHub: examples/01_standalone_sdk/07_mcp_integration.py

Here’s an example integrating MCP servers with an agent:

examples/01_standalone_sdk/07_mcp_integration.py

import os

from pydantic import SecretStr

from openhands.sdk import (
    LLM,
    Agent,
    Conversation,
    Event,
    LLMConvertibleEvent,
    get_logger,
)
from openhands.sdk.security.llm_analyzer import LLMSecurityAnalyzer
from openhands.sdk.tool import Tool
from openhands.tools.file_editor import FileEditorTool
from openhands.tools.terminal import TerminalTool


logger = get_logger(__name__)

# Configure LLM
api_key = os.getenv("LLM_API_KEY")
assert api_key is not None, "LLM_API_KEY environment variable is not set."
model = os.getenv("LLM_MODEL", "openhands/claude-sonnet-4-5-20250929")
base_url = os.getenv("LLM_BASE_URL")
llm = LLM(
    usage_id="agent",
    model=model,
    base_url=base_url,
    api_key=SecretStr(api_key),
)

cwd = os.getcwd()
tools = [
    Tool(name=TerminalTool.name),
    Tool(name=FileEditorTool.name),
]

# Add MCP Tools
mcp_config = {
    "mcpServers": {
        "fetch": {"command": "uvx", "args": ["mcp-server-fetch"]},
        "repomix": {"command": "npx", "args": ["-y", "repomix@1.4.2", "--mcp"]},
    }
}
# Agent
agent = Agent(
    llm=llm,
    tools=tools,
    mcp_config=mcp_config,
    # This regex filters out all repomix tools except pack_codebase
    filter_tools_regex="^(?!repomix)(.*)|^repomix.*pack_codebase.*$",
)

llm_messages = []  # collect raw LLM messages


def conversation_callback(event: Event):
    if isinstance(event, LLMConvertibleEvent):
        llm_messages.append(event.to_llm_message())


# Conversation
conversation = Conversation(
    agent=agent,
    callbacks=[conversation_callback],
    workspace=cwd,
)
# Set security analyzer via conversation (new approach after deprecation)
conversation.set_security_analyzer(LLMSecurityAnalyzer())

logger.info("Starting conversation with MCP integration...")
conversation.send_message(
    "Read https://github.com/OpenHands/OpenHands and write 3 facts "
    "about the project into FACTS.txt."
)
conversation.run()

conversation.send_message("Great! Now delete that file.")
conversation.run()

print("=" * 100)
print("Conversation finished. Got the following LLM messages:")
for i, message in enumerate(llm_messages):
    print(f"Message {i}: {str(message)[:200]}")

# Report cost
cost = llm.metrics.accumulated_cost
print(f"EXAMPLE_COST: {cost}")

Running the Example

export LLM_API_KEY="your-api-key"
cd agent-sdk
uv run python examples/01_standalone_sdk/07_mcp_integration.py

MCP Configuration

Configure MCP servers using a dictionary with server names and connection details following this configuration format

mcp_config = {
    "mcpServers": {
        "fetch": {"command": "uvx", "args": ["mcp-server-fetch"]},
        "repomix": {"command": "npx", "args": ["-y", "repomix@1.4.2", "--mcp"]},
    }
}

Tool Filtering

Use filter_tools_regex to control which MCP tools are available to the agent

agent = Agent(
    llm=llm,
    tools=tools,
    mcp_config=mcp_config,
    filter_tools_regex="^(?!repomix)(.*)|^repomix.*pack_codebase.*$",
)

MCP with OAuth

This example is available on GitHub: examples/01_standalone_sdk/08_mcp_with_oauth.py

For MCP servers requiring OAuth authentication:

examples/01_standalone_sdk/08_mcp_with_oauth.py

import os

from pydantic import SecretStr

from openhands.sdk import (
    LLM,
    Agent,
    Conversation,
    Event,
    LLMConvertibleEvent,
    get_logger,
)
from openhands.sdk.tool import Tool
from openhands.tools.file_editor import FileEditorTool
from openhands.tools.terminal import TerminalTool


logger = get_logger(__name__)

# Configure LLM
api_key = os.getenv("LLM_API_KEY")
assert api_key is not None, "LLM_API_KEY environment variable is not set."
model = os.getenv("LLM_MODEL", "openhands/claude-sonnet-4-5-20250929")
base_url = os.getenv("LLM_BASE_URL")
llm = LLM(
    usage_id="agent",
    model=model,
    base_url=base_url,
    api_key=SecretStr(api_key),
)

cwd = os.getcwd()
tools = [
    Tool(
        name=TerminalTool.name,
    ),
    Tool(name=FileEditorTool.name),
]

mcp_config = {
    "mcpServers": {"Notion": {"url": "https://mcp.notion.com/mcp", "auth": "oauth"}}
}
agent = Agent(llm=llm, tools=tools, mcp_config=mcp_config)

llm_messages = []  # collect raw LLM messages


def conversation_callback(event: Event):
    if isinstance(event, LLMConvertibleEvent):
        llm_messages.append(event.to_llm_message())


# Conversation
conversation = Conversation(
    agent=agent,
    callbacks=[conversation_callback],
)

logger.info("Starting conversation with MCP integration...")
conversation.send_message("Can you search about OpenHands V1 in my notion workspace?")
conversation.run()

print("=" * 100)
print("Conversation finished. Got the following LLM messages:")
for i, message in enumerate(llm_messages):
    print(f"Message {i}: {str(message)[:200]}")

Running the Example

export LLM_API_KEY="your-api-key"
cd agent-sdk
uv run python examples/01_standalone_sdk/08_mcp_with_oauth.py

OAuth Configuration

Configure OAuth-enabled MCP servers by specifying the URL and auth type
The SDK automatically handles the OAuth flow when first connecting
When the agent first attempts to use an OAuth-protected MCP server’s tools, the SDK initiates the OAuth flow via FastMCP
User will be prompted to authenticate
Access tokens are securely stored and automatically refreshed by FastMCP as needed

mcp_config = {
    "mcpServers": {
        "Notion": {
            "url": "https://mcp.notion.com/mcp",
            "auth": "oauth"
        }
    }
}
