tesla-safety

tesla-safety is a cursor rule for Cursor from supervised-nl/tesla-fleet-mcp. It costs 207 tokens per session, scanned A, original, MIT.

A set of safety rules for controlling Tesla vehicles through an agent. It protects vehicle identifiers and requires confirmation before actions that change the car.

In plain words
What is it for?
It helps the agent read vehicle information and handle lock, climate, charging, and wake commands with the required checks.
Why use it?
It prevents secrets such as VINs and access tokens from appearing in chat or logs. It also reduces accidental locking, climate changes, charging changes, or waking the car.

Cursor rule for Cursor

Written for Cursor: a Cursor rule (.mdc).

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

tesla-safety scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Tesla safety

  • Never print VIN, Tesla Fleet tokens, Tessie tokens, refresh tokens, client secrets, or TESLA_MCP_TOKEN in chat or logs.
  • Refer to the vehicle by display name or model, not VIN.
  • Use the plugin MCP server tesla. Do not add a second Tesla MCP server.
  • Reads: vehicles_list, vehicle_get, vehicle_data, nearby_chargers. Prefer vehicle_get. Do not wake the car for status unless the user asked.
  • Writes: door_lock, door_unlock, climate_start, climate_stop, set_temps, charge_start, charge_stop, set_charge_limit, wake_up. Ask the user to confirm the action first. Do not skip the question.
  • Do not poll vehicle_data. Tesla bills per call.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
