### Description (declared)

# Evolution MCP

Modal-backed MCP server for evaluating multiple agent-generated code variants in
parallel.

Codex runs locally and generates candidate patches or full-file writes. Modal
only evaluates those variants:

1. Sync the dirty local repo into a Modal image with `Image.add_local_dir`.
2. Start a setup sandbox and run setup commands once.
3. Snapshot the prepared filesystem with `Sandbox.snapshot_filesystem`.
4. Start `run_experiment`; it returns immediately with `status: running`.
5. Enqueue a durable Redis Stream job.
6. A worker process claims the job and forks one Modal sandbox per variant.
7. Apply each patch or full-file write inside its sandbox.
8. Run the same eval command in each sandbox.
9. Persist result metadata and artifacts to Redis.
10. Poll `get_experiment` until completed.
11. Optionally call `apply_winner` to apply the winning diff locally.

## Install

```bash
uv sync
```

For a published package, the intended install shape is:

```bash
uvx --from evolution-mcp evolution-mcp-doctor
```

## Configure Modal

```bash
uv run modal setup
```

The controller uses your local Modal credentials to create images, sandboxes,
and snapshots. Eval sandboxes do not need OpenAI credentials. Only pass
`secret_names` when the repo's own setup or tests need secrets.

## Configure Redis

V2 uses Redis for durable workspace records, experiment records, statuses, and
small artifacts.

```bash
export REDIS_URL=redis://localhost:6379/0
```

Redis must be running before normal use:

```bash
brew install redis
brew services start redis
```

For dev-only local JSON persistence:

```bash
export EVOLUTION_MCP_STORAGE=local
```

## Doctor

```bash
uv run evolution-mcp-doctor
```

This checks storage, checks the active Modal profile, and prints a Codex MCP
config snippet.

## Run The MCP Server

```bash
uvx --from evolution-mcp evolution-mcp
```

## Run A Worker

Run at least one worker process alongside the MCP server:

```bash
uvx --from evolution-mcp evolution-mcp-w…
