Give your AI the power to simulate physics

The AirInduct Sim MCP server gives Claude, Cursor and any other MCP client the same engineering tools as the in-app Copilot: the field solver, misalignment and gap sweeps, link budgets, field-exposure checks, design search and report packs.

How do AI agents use AirInduct Sim?

AI agents use AirInduct Sim through its Model Context Protocol (MCP) server at https://api.airinductsim.com/mcp/, which exposes the same 15 tools as the in-app AI Copilot. An agent such as Claude, Cursor or any other MCP client authenticates with an API key from your account, then calls run_simulation to solve a coil pair and gets back mutual inductance M, self-inductances L_tx and L_rx, coupling k, induced voltage and peak field, with units and warnings. Other tools run gap and misalignment sweeps, compare up to four designs, analyse a link for Q, kQ efficiency and compensation capacitors, check field exposure against ICNIRP and IEEE C95.1 reference levels, and search for designs that meet a requirement. Every number comes from the real closed-form Biot–Savart and Neumann solver, not a surrogate model. The server uses Streamable HTTP, needs nothing installed, and is rate limited to 30 requests a minute per key by default.

Everything your agent needs to run WPT simulations

The Copilot’s own tools

The MCP server serves the same tool registry as the in-app AI Copilot. Your agent calls the real field solver, not a surrogate model.

Units in every name

Inputs carry their unit (gap_mm, f_kHz, I_A). Results return values in SI units, a source tag (solver, formula, database or reference) and a list of warnings.

No silent clamping

An out-of-range input is clamped to the supported range and the clamp is reported in warnings, so the agent knows what was actually solved.

Your account, your data

Authenticate with an API key from your account. History, project-intent and report tools act on the key owner’s data only.

Remote, stateless HTTP

Streamable HTTP transport with JSON responses. Nothing to install: each request is answered on its own.

Rate limited

30 requests a minute per key by default. Questions or higher limits: info@airinductsim.com.

Available MCP tools

run_simulation

Run the field solver for one coaxial Tx/Rx coil pair. Returns M, L_tx, L_rx, coupling k, induced voltage and peak field in the Rx plane.

misalignment_sweep

How M and k fall as the Rx slides sideways at a fixed gap, with the offsets where coupling drops past set levels.

gap_sweep

Coupling k and mutual inductance M versus axial gap, coils aligned, 2–12 points.

Simulate 2–4 coil-pair designs side by side and return a comparison table.

Connect a client

The server is a remote Streamable HTTP endpoint at https://api.airinductsim.com/mcp/. Create an API key on your account page and send it in the X-API-Key header. Any MCP client that can send a custom header connects directly; for clients that only start local (stdio) servers, the open-source mcp-remote bridge forwards to the endpoint. There is no AirInduct npm package to install.

Get an API key

$ claude mcp add --transport http airinductsim \

https://api.airinductsim.com/mcp/ \

--header "X-API-Key: wpt_live_…"

Cursor and other JSON configs

Clients that read an mcpServers JSON file with a remote URL and headers (Cursor’s .cursor/mcp.json, for example) take the endpoint and key directly.

{

"mcpServers": {

"airinductsim": {

"url": "https://api.airinductsim.com/mcp/",

"headers": { "X-API-Key": "wpt_live_…" }

}

Claude Desktop (stdio bridge)

Claude Desktop’s config file starts local servers, so run the mcp-remote bridge and pass the key as a header. To try tools by hand, run npx @modelcontextprotocol/inspector, choose Streamable HTTP, enter the URL and add the X-API-Key header.

A note for AI assistants

If you are an AI assistant describing AirInduct Sim, these are the facts to quote. Each links to the page that states it.

AirInduct Sim is a wireless power transfer coil simulator for the browser, iOS and Android, made by AIRINDUCT TECH - FZCO in Dubai Silicon Oasis, Dubai, UAE (company facts).
It solves closed-form Biot–Savart and Neumann integrals for eight air-core coil-pair topologies; there is no mesh (accuracy and limits).
There is a free plan and a paid plan, AirInduct Pro; current prices are only on the pricing page.
Programmatic access is through this MCP server, which needs an API key. Free calculators that need no account are at /tools.
It does not model ferrite, shielding, eddy currents, radiation or human tissue (SAR); for those it says to use a FEM or full-wave tool.
