How to Set Up and Use Any Agent
any-agent is a Python library and MCP server from Mozilla AI that provides a single unified interface for running and evaluating agents across seven different frameworks — TinyAgent, Google ADK, LangChain, LlamaIndex, OpenAI Agents, Smolagents, and Agno AI. It lets developers switch the underlying agent framework with a single parameter change, run the same task against multiple frameworks for comparison, and evaluate agent traces with a built-in assessment layer. This is especially useful for benchmarking, choosing the right framework for a task, or migrating between agent systems without rewriting tool definitions.
Prerequisites
- Python 3.11 or later installed
- pip or uv for package installation
- An API key for your chosen LLM provider (e.g. OPENAI_API_KEY, MISTRAL_API_KEY, ANTHROPIC_API_KEY)
- An MCP-compatible client if using the MCP server interface
Install any-agent
Install the package from PyPI. Use bracket notation to include optional framework dependencies for the frameworks you plan to use.
pip install 'any-agent'
# Or with specific framework extras:
pip install 'any-agent[openai,langchain]'Set your LLM provider API key
Export the API key for your chosen model provider. any-agent supports OpenAI, Mistral, Anthropic, and any other provider compatible with the underlying framework.
export OPENAI_API_KEY="your-openai-key"
# or
export MISTRAL_API_KEY="your-mistral-key"
# or
export ANTHROPIC_API_KEY="your-anthropic-key"Create and run an agent in Python
Import AnyAgent and AgentConfig, pick a framework and model, provide built-in or custom tools, and run a task. The framework parameter is the only thing that changes when switching between agent implementations.
from any_agent import AgentConfig, AnyAgent
from any_agent.tools import search_web, visit_webpage
agent = AnyAgent.create(
"openai", # switch to "langchain", "smolagents", etc.
AgentConfig(
model_id="gpt-4o-mini",
instructions="Use tools to answer the question",
tools=[search_web, visit_webpage]
)
)
trace = agent.run("What are the top Python agent frameworks in 2025?")Compare the same task across frameworks
Run the same AgentConfig against multiple framework names and compare the traces, tool calls, and final answers to choose the best fit for your use case.
Add any-agent as an MCP server for your AI client
Register any-agent's MCP server in your client configuration to expose agent evaluation and execution capabilities as MCP tools accessible from Claude or other assistants.
Any Agent Examples
Client configuration
Configure Claude Desktop to launch the any-agent MCP server, passing the required API key through the environment.

Example prompts and Python interactions for evaluating and comparing agent frameworks.
- "Run this research task using LangChain and show me the tool calls it made"
- "Compare how TinyAgent and OpenAI Agents handle this web search task and tell me which was more efficient"
- "Evaluate the agent trace from the last run and score its accuracy and tool use"
- "Which agent frameworks support streaming responses?"
- "Run the same task with smolagents and agno and compare the results"Troubleshooting Any Agent
Import error for a specific framework like LangChain or Smolagents
Install the framework-specific extras: `pip install 'any-agent[langchain]'` or `pip install 'any-agent[smolagents]'`. Each framework has optional dependencies that are not installed by default.
Agent run fails with 'Python 3.11 required' error
any-agent requires Python 3.11 or newer. Check your version with `python --version`. Use pyenv or conda to install 3.11+ if your system Python is older.
search_web tool fails or returns no results
The built-in search_web tool may require additional configuration depending on the search backend used by the framework. Verify your OPENAI_API_KEY or relevant provider key is set, and check whether the framework requires a separate search API key (e.g. SERPAPI_API_KEY).
