How to connect
How to connect DiffBeam Gaussian Beam Optics to Claude
The server address to paste into Claude settings:
https://catalog-api.gaussian-beam.com/mcp/
- Open Claude (claude.ai or the desktop app).
- Go to Settings → Connectors.
- Click Add custom connector.
- Paste the server address copied below into Remote MCP server URL and click Add.
- In a chat, click + → Connectors and switch the new connector on.
Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.
Authorization
After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.
How to connect DiffBeam Gaussian Beam Optics to ChatGPT
The server address to paste into ChatGPT settings:
https://catalog-api.gaussian-beam.com/mcp/
- Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
- Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
- Open Settings → Connectors and click Create.
- Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
- Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
- In a new chat open + → Apps/Connectors and enable the connector.
OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.
Authorization
On first use ChatGPT opens the service's sign-in window. Sign in and approve access.
How to connect DiffBeam Gaussian Beam Optics to Cursor
The server address to paste into Cursor settings:
https://catalog-api.gaussian-beam.com/mcp/
Fastest: click Open in Cursor below and confirm the prompt.
Manually:
- In Cursor open Settings → Cursor Settings → MCP and click Add new global MCP server.
- Paste the JSON copied below into
~/.cursor/mcp.json(per project:.cursor/mcp.jsonin the repo root). - Save the file. The server appears in the MCP list; authorize it there if asked.
Authorization
If the service needs sign-in, an authorize button appears next to the server in the MCP list.
Server tool list (4)
Raw names from tools/list. Only developers need these.
| get_diffbeam_state | Check whether DiffBeam protocol, tools, or catalog data changed. If `changed` is true, refresh tool schemas and repeat any catalog searches before citing part numbers. This tool is read-only, fast, and stateless. |
| search_fibers | Search public fiber catalog rows. Use when the user asks for real fiber part numbers, links, mode-field diameter, numerical aperture, wavelength compatibility, or attenuation. Returns only catalog data and public URLs; it never reads or writes planner workspaces. Retry only after changing the query or when the server returns a transient transport error. |
| search_fiber_collimators | Search public fiber-collimator catalog rows. Use when the user asks for real collimator/coupler part numbers, links, EFL, coating range, connector type, clear aperture, or vendor data. Do not use as a generic Gaussian-beam solver; it only returns catalog matches. |
| search_lenses | Search public lens catalog rows. Use when the user asks for real lens part numbers, links, focal lengths, diameters, coatings, or purchasable candidates for a design. Return matches as evidence; never claim a part exists unless it appears in the result. |
