Building autonomous coding agents is easy. Figuring out how to evaluate whether what they've done is actually good is incredibly hard. 

`agent-eval-mcp` is a stateless, deterministic Model Context Protocol (MCP) server that stops AI agents from writing lazy, unverified, or hallucinated code. It provides language-agnostic rulesets and hybrid scoring to grade AI-generated revisions *before* they get merged.

## ⚠️ The Problem

When you ask an LLM to evaluate its own code, it suffers from sycophancy. It will confidently tell you its fix is perfect, even when it has:
* Generated dummy patterns like `new HashMap<>()` or `pass`.
* Left `// TODO: implement this` in the production patch.
* Hallucinated the surrounding `SEARCH/REPLACE` context, breaking the Git patch.

## 💡 The Solution

This package exposes objective evaluation tools to your agentic workflows via the **Model Context Protocol (MCP)**. It evaluates AI-generated code edits using fuzzy-matching and language-specific Abstract Syntax Tree (AST) rules (Java, Python, TypeScript, Go) to catch hallucinations deterministically.

It supports two edit formats:
- **Cursor SEARCH/REPLACE blocks** — for interactive agentic coding sessions.
- **Standard unified diffs** — for CI/CD pipelines and GitHub Action workflows, where diffs come from Pull Requests or `git diff` output.

It completely decouples the heavy lifting of code validation from your LLM orchestration layer.
