This listing does not currently have a tool list to display. This does not mean the server has no tools; check its documentation for supported capabilities.

We auto-extract tools from the README. The maintainer can list them under a ## Tools heading to populate this section.

Overview

What is Model Context Protocol (MCP) Agent Frameworks Demo?

The Model Context Protocol (MCP) Agent Frameworks Demo is a demonstration and benchmarking platform that shows how to integrate Model Context Protocol (MCP) servers with multiple LLM agent frameworks: Google Agent Development Kit (ADK), LangGraph Agents, OpenAI Agents, and Pydantic‑AI Agents. It includes example Python MCP servers and a comprehensive evaluation suite for benchmarking LLM performance on mermaid diagram correction tasks.

How to use Model Context Protocol (MCP) Agent Frameworks Demo?

Set environment variables (GEMINI_API_KEY and/or OPENAI_API_KEY) in a .env file, then run one of the example scripts, e.g., uv run agents_mcp_usage/basic_mcp/basic_mcp_use/pydantic_mcp.py. For benchmarking, use make benchmark MODEL="..." RUNS=5 PARALLEL=1 or the multi‑model evaluation scripts. Optional LOGFIRE_TOKEN enables tracing visualisation in the Logfire web UI.

Key features of Model Context Protocol (MCP) Agent Frameworks Demo

  • Supports single and multiple MCP server coordination
  • Provides comprehensive evaluation and benchmarking suite
  • Offers interactive Streamlit dashboard for model comparison
  • Uses Pydantic Logfire for tracing and debugging

Use cases of Model Context Protocol (MCP) Agent Frameworks Demo

  • Learning how to connect MCP servers to different agent frameworks
  • Benchmarking LLM performance on mermaid diagram correction tasks
  • Evaluating cost, accuracy, and speed across multiple models
  • Developing modular, scalable agent architectures with multiple MCP servers

Frequently asked questions

1

What is MCP?

The Model Context Protocol allows applications to provide context for LLMs in a standardised way, separating the concerns of providing context from the actual LLM interaction.

2

Which agent frameworks are demonstrated?

Google Agent Development Kit (ADK), LangGraph Agents, OpenAI Agents, and Pydantic‑AI Agents are demonstrated.

3

What MCP servers are included in the repository?

Two Python MCP servers: `example_server.py` (provides an `add(a,b)` tool, `get_current_time()` tool, and a dynamic greeting resource) and `mermaid_validator.py` (Mermaid diagram validation using mermaid‑cli).

4

How do I run a single‑model benchmark?

Use the Makefile command: `make benchmark MODEL="openai:gpt-5.2 (none)" RUNS=5 PARALLEL=1` to run a Dockerised single‑model benchmark with isolated dependencies.

5

What tracing tool is used?

Tracing is done through Pydantic Logfire. An optional `LOGFIRE_TOKEN` can be set to visualise evaluations in the Logfire web UI.
