AI agents, MCP and evaluation

Agents with tools, the Model Context Protocol and the part most teams skip: an evaluation set and guardrails before production.

Who it is for

Engineers who have built an LLM prototype and now want an agent they can trust in production.

What you can do afterwards

  • Build an agent that calls tools through MCP
  • Write an evaluation set and a regression gate for it
  • Put a guardrail between the agent and a risky action
  • Sit the Context Engineer Associate exam

  6. Build

    An agent with one tool, one eval set and one guardrail

    Goal. Build a small agent that uses one tool, and make it safe to change by testing it.

    What to do

    1. Expose one useful read-only tool through an MCP server.
    2. Write 15 tasks with the result you expect, including three the agent should refuse.
    3. Run them on every change and fail the build when the pass rate drops.
    4. Add a guardrail that asks a human before any action that changes data.

    What good looks like. You can change the prompt or the model and know within minutes whether the agent got better or worse.
