Alita-G: Are MCP Toolboxes Real Expertise Or Prompt Packaging?

Read the original sourceWhat the paper says
Alita-G turns a general agent into a domain specialist by generating, abstracting, curating, and retrieving Model Context Protocol tools. The system builds an MCP Box and selects relevant components at inference time.
The Critique
This is useful engineering, but it may be closer to reusable prompt/tool packaging than true self-evolution. If the generated MCPs are based on successful past trajectories, they can encode accidental shortcuts as reusable primitives. The system also depends heavily on accurate retrieval: a strong specialist can become a confused specialist if the wrong MCP is selected for a superficially similar task.
Why It Matters
Agent toolboxes are becoming a practical route to domain-specific AI. The danger is that a neat library of tools creates the appearance of expertise without the judgement to know when a tool does not apply.
What They Missed
Stress tests for misleadingly similar tasks, stale MCPs, conflicting MCPs, and domains where there is no clean reusable procedure.
The Big Question
Is Alita-G building domain expertise, or building a better filing cabinet for prompts?
