Common questions

Is DiffBeam Gaussian Beam Optics safe?

It passed 0 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.0.0) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

DiffBeam by Gaussian Beam

DiffBeam is a deterministic Gaussian beam optics service for AI agents and engineering tools. Its anonymous MCP searches optical component catalogs and reports server/catalog revisions. A separate credentialed Direct Agent Bridge analyzes and applies revisioned edits to a user's Gaussian Beam planner workspace.

DiffBeam does not host or proxy a language model. Bring any compatible AI client.

Remote MCP server

Endpoint: https://catalog-api.gaussian-beam.com/mcp/
Release: 2.0.0
Registry name: com.gaussian-beam/diffbeam
Human-readable documentation: https://gaussian-beam.com/mcp/
Machine-readable manifest: https://gaussian-beam.com/.well-known/mcp/server.json
Contracts: https://gaussian-beam.com/mcp/contracts/

MCP clients connect directly with Streamable HTTP. The public endpoint is anonymous, stateless, and read-only. It has no solver, design-link, or workspace authority.

No-install Direct Agent Bridge

An internet-capable AI that can send HTTPS POST requests does not need native MCP installation. The planner's Connect your AI dialog creates a workspace-specific endpoint, temporary scoped credential, and ready-to-copy prompt. The normal flow is:

get_workspace
make one small planner-native operation such as add_lens or set_wavelength
inspect the returned beam feedback and explain the visible revision
refine with the next useful operation; use dry_run only for explicit preview-only work

Read the Direct Agent Bridge guide. Never put a workspace credential in a URL, public page, model configuration, log, or repository.

Public MCP tools

get_diffbeam_state
search_fibers
search_fiber_collimators
search_lenses

Credentialed bridge operations

The bridge is not part of the anonymous MCP. It uses the temporary capability from Connect your AI and groups operations into:

workspace reads, changes, and revision history;
deterministic solving, beam summaries, waist finding, and point measurement;
fiber, collimator, and lens catalog searches;
planner-native source, element, parameter, unit, and beam-target mutations;
undo and revision restore.

Writes require the current expected_revision and create a live planner revision by default. The public MCP cannot access these operations.

Worked optical-design guides

The JSON file in examples/ is a planner-import example for documentation and bridge workflows. It is not an argument accepted by the anonymous catalog MCP.

Repository scope

This public repository contains discovery metadata and integration documentation. It deliberately contains no production credentials, private workspace data, telemetry, or deployment configuration. The documents and examples are licensed under Apache-2.0.

Security issues should be reported privately as described in SECURITY.md.
