What can I ask?

Your question. Your numbers.

Ask in your own words, as you ask an engineer. Here is one real question about a practice on the old Südschleife, as you see it in your assistant.

Claude apexracing connected

Lap 4 on the old Südschleife was 3.6 s faster than lap 2. Where did I find the time?

apexracing 6 of 6 tool calls

list_sessions 4 laps, 2 Nov track Nurb_1971, last 7 days
list_laps best 2:57.480, lap 4 session b3f76963

analyze_braking_zone 146 / 186 km/h 5,150 to 5,700 m

3.2 of the 3.6 s come from two places.

At 5.3 km you lift early on lap 2 and coast from 195 to 145 km/h before you brake. On lap 4 you stay flat to 5,301 m and brake from 186 km/h. That is 2.16 s.

At 1 km lap 2 has a big correction, steering 0.84 against 0.21, and slows to 85 km/h. Lap 4 holds 110 km/h. That is 1.04 s.

Your own words

Name the track and the laps. You need no ids and no tool names.

list_sessions found the session from the track name

Six calls, one answer

Your assistant selects the tools and their order. It shows each call, so you can check each number.

3.2 of the 3.6 s found in 6 calls

Only your data

The tools read the sessions of the account that signs in, and nothing else.

Every tool reads one account

Which tools does it use?

You ask. It picks the tools.

You never name a tool. Your assistant reads your question, calls the tools that answer it and shows each call.

You ask

“Practice is done. What is the best strategy for Sunday’s one hour race?”

Your assistant calls 3 tools

list_sessions Monza practice55 laps
analyze_fuel_consumption practice3.23 L per lap
simulate_race_strategy 60 min, 4 plans1 stop

1 stop

After lap 16, with new tyres. Start with 55 L and add 55 L at the stop. Two stops is the same within 1.4 s.

63 tools: 38 for your laps, 25 for your league server. See all tools in the help

Measured, not guessed

Times come from recorded timestamps. Each answer carries its warnings and a confidence.

Südschleife question: time_source recorded, confidence high

Knowledge of the game

get_game_knowledge gives curated facts per game, car class and track. Only public entries leave Apex Racing.

128 public entries match the Südschleife session

Pictures, too

Two tools draw: a telemetry chart and the racing lines of a corner. Your assistant shows the image.

render_telemetry_chart, render_racing_line

Who can use which tools?

Your laps for you.
The server for its admins.

Every person with full access gets 45 tools: 38 for their laps and 7 that read a game server. The 18 tools that change a game server show only for the owner and the admins of its league.

	Your laps 38 tools	Server, read 7 tools	Server, control 18 tools
Without full access The trial ended and no plan is active.	Each call answers with a link to your billing page. p0 still records your laps.
With full access Trial or plan, no league with a server.	Your sessions, laps and telemetry	The list is empty	Not in the tool list
Member of a league The league has a game server.	Your sessions, laps and telemetry	Schedule, settings, live timing	Not in the list. A call names whom to ask

The answer to a memberrestart_server

“Only M. Keller and the admins J. Brandt and L. Varga of Thursday Night GT3 can change this server. Ask one of them.”

The answer names the owner and the admins. A person outside the league only reads “Server not found, or not visible to you.”

Server logvia MCP

[email protected] via MCP

Each change through MCP writes a line in the Log of the Server tab, like a change on the web.

Checked on every call

Apex Racing checks your role at each call, also when a client keeps an old tool list.

The same rule as the Server tab

Asks before a kick

kick_driver and block_driver are marked as destructive, so your assistant asks you first.

9 of 18 control tools

Not everything

Race results, handicaps, the race director and the cars of an official round stay on the web.

Official sessions follow the season
