Base adapter interface for MCP tools. This module provides the abstract base class that all MCP tool adapters should inherit from.

​
BaseAdapter

from mcp_use.agents.adapters.base import BaseAdapter

​
method init

Initialize a new adapter.Parameters
​
disallowed_tools
list[str] | None
default:"None"
list of tool names that should not be available.
Signature
def __init__(disallowed_tools: list[str] | None = None):
