Stabilizing Agent Swarms: A Guide to Model Conduct Protocol (MCP) Evaluations
As CEO of Fruit Signals, Ari Helchuk explores the power of Model Conduct Protocol (MCP) in stabilizing AI-based agents, workflows, and swarms, enabling more robust evaluations and self-improvement.
- 1. Ari Helchuk is the CEO of Fruit Signals, a platform for measuring, controlling, and optimizing LLM (Language Learning Model) based agents, chatbots, and workflows.
- 2. The question at hand is whether agent evaluation by MCP (Model Conduct Protocol) could stabilize agents and agent networks/swarms.
- 3. Stable agent swarms can theoretically solve any knowledge work problems, but tend to be unstable when solving complex problems due to observation difficulties, inability to test comprehensively bef
- 4. The solution to this problem involves evaluation or 'evals', but not just by adding an eval stack; systematic usage and continuous development of evaluations are crucial for improvement.
- 5. Evaluating all aspects of agent behaviors and internal representations is complex and includes both reality representation (agent models, discussions, grounding) and behavioral aspects (goal infere
- 6. To get started, a clear framework for setting up evaluators is needed; an example was given using a reservation agent for a hotel with evaluators like policy adherence, accuracy of outputs, and app
- 7. Fruit Signals has implemented this evaluator setup, providing good visibility to create, maintain, and improve large stacks of evaluators systematically over time.
- 8. The goal is to create a stabilization loop where the agent's output gets evaluated by an evaluation engine, receiving feedback in the form of a numeric score and explanation for improvement or succ
- 9. Agents can use this information to improve their own performance; the Model Context Protocol (MCP) is the latest method for attaching these agents to the new greatest method.
- 10. MCP allows users to measure and improve specific text or output from an agent, using charges (collections of evaluators), and universal evaluators available on the server.
- 11. The MCP server provides access to evaluators through a UI like Cursor, enabling users to optimize marketing messages by specifying the charge for evaluation.
- 12. For the marketing message example, the system found issues with the text, tried to improve it, and displayed final scores for persuasiveness, quality, writing, and engagingness.
- 13. The agent can either explicitly choose evaluators and charges or let them be picked automatically; this was demonstrated using a simple hotel reservation agent implemented on Pyantic AI.
- 14. Without MCP, the reservation agent politely mentions another hotel (Akma), which is not desired; with MCP, the agent no longer mentions it due to policy adherence evaluation.
- 15. The MCP server evaluates agents through lists of evaluators and makes calls back and forth, enabling agents to improve their own behavior by invoking relevant evaluators from the list.
- 16. Users should ensure their evaluation platform is powerful enough to support diverse evaluators, their life cycle maintenance, optimization, and scaling for complex examples.
- 17. Running MCP manually offline before attaching it to agents helps users understand how it works and gain transparency.
- 18. Attaching the evaluation engine through MCP makes the process more controllable, transparent, and dynamically self-improving/self-correcting.
- 19. The root signals MCP server is available for free; other similar platforms will appear, enabling various evaluation frameworks to be implemented as part of an agent stack.
- 20. The presentation emphasizes the importance of agents, evaluations, and the symbiotic relationship between them.
- 21. The use of MCP can help in controlling, optimizing, and improving agent behavior while ensuring consistent performance.
- 22. A stable agent network or swarm can significantly contribute to solving complex knowledge work problems by enabling better decision-making and task completion.
- 23. Fruit Signals aims to simplify the process of evaluating agents using MCP and related tools, empowering developers to create more efficient and effective AI systems.
- 24. The future of agent evaluation lies in platforms that provide dynamic self-improvement, self-correction, and seamless integration with various agent stacks.
