What I can help withEngineering practice by Igor Bartenev

MCP & AI agent infrastructure

An agent needs more than access to an LLM. It needs to find the right tool, receive enough context and act within explicit permissions. I build the infrastructure around that loop. MCP Hub is the deeper platform example: integrations, project knowledge, retrieval, orchestration and reusable execution experience.

How I approach the work

  1. Discover before loading

    Expose a compact discovery surface and return the relevant capabilities with typed argument hints. Retrieve bounded knowledge fragments through lexical and embedding-based search instead of inserting an entire knowledge base into every prompt.

  2. Control actions and results

    Check provider and project access on the server, keep approval state explicit and record execution results. Orchestration needs budgets, bounded parallelism and cancellation. A tool call accepted by the transport is not proof that the business action succeeded.

  3. Reuse experience deliberately

    Store useful methods and scoped outcomes from completed work, then retrieve them for a relevant task. MCP Hub treats this as reusable knowledge and execution history, not as training the model’s weights. Compact result handling limits unnecessary context growth.

A decision to make early

Reducing the tool surface can save context, but exact token savings depend on schemas, tasks and the model. The linked Unity MCP Efficient case has a specific schema comparison; it is not a universal savings claim for every MCP Hub workflow.

Tell me about your task

Describe the task the agent should complete, the systems it may access and the actions that need human approval. Include the current failure mode: tool selection, missing context, cost or unreliable execution.
