### Description (declared)

# ensemble-mcp

A **harness infrastructure layer** delivered as a Python MCP server — providing **vector memory**, **drift detection**, **model routing**, **skills discovery**, **session management**, **codebase indexing**, and **context compression** for AI agent pipelines.

All intelligence is local — zero LLM/API calls. Uses ONNX Runtime embeddings (~5ms), numpy cosine similarity, and SQLite storage.

## What is an Agent Harness?

**Agent = Model + Harness.** A harness is every piece of code, configuration, and execution logic that wraps a model to turn it into a useful agent. Without a harness, a model can only take in text and output text — it can't maintain state, execute code, access tools, or learn from past work.

A complete agent harness typically includes:

- **System prompts & configuration** — instructions that shape agent behavior
- **Tools, Skills & MCPs** — capabilities the agent can invoke
- **Execution environment** — filesystem, bash, sandbox, browser
- **Orchestration logic** — subagent spawning, handoffs, model routing
- **Memory & context management** — compaction, skills, session persistence
- **Hooks & middleware** — deterministic checks like linting, formatting, drift detection

## Where ensemble-mcp Fits

Agent harnesses like Claude Code, Codex, and Cursor provide the **execution layer** — filesystem, bash, sandbox. ensemble-mcp provides the **intelligence infrastructure layer** that plugs into any harness via MCP:
