Should I use this
Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢search_components(component_type, query, limit, offset, sort_by, ...)
Find motors, propellers or batteries in the ThrustLab database. `component_type` is "motor", "propeller" or "battery". `query` is a case-insensitive substring of the part name or its maker ("APC", "T-Motor", "13x6.5"). The maker sits under `spec.brand` for motors and batteries and under `spec.type` for propellers. `limit` is capped at 200 rows a page; when `has_more` is true, pass the returned `next_offset` as `offset` to read the next page. Each row carries its datasheet values, its source and the CC BY 4.0 attribution line. Pass a returned `id` to `simulate_powertrain`.

}🟢get_component(component_id)
Read one database row by its id (`comp_…`), with provenance. Propeller rows give diameter, pitch, blade count, weight and maximum rpm. Blade station geometry is never returned.

}🟢estimate_propeller(diameter_in, pitch_in, rpm, blades, airspeed_m_s, ...)
Thrust, torque and shaft power for one propeller, from its printed size. A closed-form momentum plus blade-element equation — no motor, no battery, no account. Give the size as it is printed: a 10x5 is `diameter_in=10`, `pitch_in=5`. `chord_ratio` is the chord at 75 % radius over the diameter: 0.065 thin electric, 0.07 sport, 0.10 slow flyer, 0.11 multirotor.

}🟢simulate_powertrain(powertrain)
Solve one operating point of a whole powertrain on the Fast model. Battery, ESC, motor and propeller are solved together, so the answer is a real thrust and current, not a propeller curve. The numbers come back in `result` (`result.All` = system totals in SI units: thrust N, current A, power W, time s; one entry per rotor; `result.Battery`), with a share URL. No second call is needed to read them.

}🟢sweep_powertrain(powertrain, sweep)
Solve a powertrain across a throttle or airspeed range, up to 25 points. `sweep.steps` is the NUMBER OF POINTS, not a step size: start 40, stop 100, steps 4 gives 40, 60, 80 and 100. One sweep beats a loop of single points. The points come back in `result.points` with the share URL; no second call is needed to read them.
