Charles MCP Server connects Charles Proxy to MCP clients so an agent can inspect live traffic, analyze saved recordings, and expand individual requests only when needed.

It focuses on three things:

- reading incremental traffic from the current Charles session while recording is still active
- keeping live and history analysis on structured paths instead of exposing raw dump dictionaries first
- using summary-first outputs so the agent can find hotspots before pulling detail

## This Release Direction (v3.0)

The `v3.0` direction is clear: `charles-mcp` is moving from pure traffic inspection toward reverse-engineering workflows.

- On top of existing live/history analysis, it now exposes a reverse-analysis tool surface (import, query, decode, replay, signature candidate discovery, and live reverse sessions).
- The goal is to let an agent go beyond traffic browsing and build an end-to-end reverse workflow around auth flows, signatures, parameter mutation, and replayability.

## Quick Start

### 1. Enable the Charles Web Interface

In Charles, open: `Proxy -> Web Interface Settings`

Make sure:

- `Enable web interface` is checked
- username is `admin`
- password is `123456`
