## Core Modules

### 1. Telemetry Analysis

Turns raw iRacing telemetry into actionable insights. Data flows from iRacing → Capture desktop app → Cloud → Web app.

**Sessions & Laps**:
- Browse all sessions with track, car, date, and session type filters
- Dive into individual laps with full telemetry data
- See lap times, sector splits, and session progression

**Braking Zone Analysis**:
- Per-corner braking data: brake point, peak pressure, trail braking curve
- MRP (Maximum Rotation Point) detection
- Deceleration profiles and brake release characteristics
- Entry/exit speed for every corner

**Track Maps**:
- GPS satellite-based racing line visualization
- See your actual line through every corner
- Compare racing lines between laps

**Lap Comparison**:
- Side-by-side comparison of 2-5 laps
- Per-zone braking deltas and time differences
- Save comparisons for future reference
- Identify where time is gained or lost

**Scoreboard**:
- Personal best rankings by track/car combination
- Filter by track, car, session type, date range
- Delta to personal best for each lap
- Consistency metrics (standard deviation)

**Coaching Reports**:
- AI-generated analysis created by the Race Engineer
- Structure: overview, pace analysis, corner-by-corner feedback, action items
- Linked to specific sessions or stints
- Prioritized improvement recommendations

### 2. Race Engineer (AI via MCP)

An AI assistant with full access to your telemetry, race calendar, track notes, and hardware setups. It connects through the Model Context Protocol (MCP) — an open standard that lets AI assistants access external tools and real user data.

This is not a chatbot with generic racing advice. The Race Engineer reads *your* actual telemetry files, *your* lap times, *your* braking data, and generates analysis specific to your sessions. It can also write back: create coaching reports, update track notes, add races to your calendar, build race strategies from your practice data.

**Architecture**:
```
You ← AI Assistant (Claude, Cursor, etc.) ← MCP → Braking Lab Race Engineer → Your Telemetry & Data
```

**Compatible MCP Clients**: Claude Desktop, Cursor, Windsurf, or any MCP-compatible client.

**Setup**: Add the Braking Lab MCP server to your MCP client configuration, authenticate with your Braking Lab account via OAuth, and start chatting. Full setup guide at https://www.brakinglab.com/en/docs/race-engineer/setup

**Available Tool Categories (56+ tools)**:

| Category | What it can do |
|----------|----------------|
| Sessions & Laps | List all sessions, filter by track/car/date, get full lap breakdown |
| Stints | Get stint metrics, corner-by-corner speed and braking data |
| Corner Analysis | Per-corner speed deltas, track structural templates, weak corner identification |
| Braking Zones | MRP values, trail braking curve shape, brake profiles, deceleration analysis |
| Coaching | Generate AI coaching reports, save them, retrieve past reports |
| Lap Comparison | Compare 2–5 laps side by side, zone-level time deltas, save comparisons |
| Race Calendar | Create/edit race events, link practice sessions to races |
| Race Preparation | Build preparation plans from templates, manage checklists and phases |
| Strategy | Generate fuel strategy and stint plan from your actual practice telemetry |
| Track Notepads | Read/write corner notes, pins, reference videos for any track |
| iRacing Schedule | Search series by license, find races this week, check schedules |
| Hardware Vault | Browse your datapacks and hardware setups |
| Leaderboard | Query public rankings by track, car, date range |
| Code Mode | Execute custom TypeScript analysis directly on your telemetry data |

**Example conversations**:

> "Analyze my last session at Spa and tell me where I'm losing the most time"
→ Race Engineer fetches your most recent Spa session, reads all laps and braking zone data, identifies the corners with the highest time loss, and gives specific actionable feedback per corner.

> "Compare my best and worst laps from today — what's different in T1?"
→ Pulls both laps, compares braking point, peak pressure, MRP, and exit speed at Turn 1. Explains the difference in concrete numbers.

> "Generate a fuel strategy for my 45-minute GTE race at Silverstone"
→ Reads your practice lap fuel consumption, calculates laps per stint, suggests pit windows and stint lengths, estimates total fuel needed.

> "I have a race at Monza next Saturday. Help me prepare."
→ Creates a race event in your calendar, generates a preparation plan from the appropriate template, links your most recent Monza practice session as reference, and pre-fills checklist items.

> "What's my weakest corner at Spa over the last month?"
→ Aggregates braking zone data from all Spa sessions in the past 30 days, ranks corners by average time loss, identifies the one with most improvement potential.

> "What's racing this week I can join with a C license on road?"
→ Queries the iRacing schedule for current week series that allow C license, road category, and returns series name, track, car classes, and schedule.

> "Write corner notes for Eau Rouge/Raidillon based on my best lap"
→ Reads braking and speed data from your best Spa lap, generates structured corner notes with brake reference distance, MRP position, and exit speed, and saves them to your Track Notepad.

**What makes this different from generic AI racing advice**:
- Works with *your* data, not generic knowledge
- Knows your actual lap times, not estimates
- Can read and write to your Braking Lab account
- Gives corner-level feedback with real numbers from your telemetry
- Remembers your race calendar and preparation state across sessions

**Data Access**:
- Read-only: Sessions, laps, braking zones, scoreboard, leaderboard, hardware vault
- Creative: Coaching reports (generates new analysis from your data)
- Mutating: Race events, track notepads, preparations (creates/updates in your account)
- All data scoped to the authenticated user's account — no access to other users' data
