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.

What search_fiber_collimators does on DiffBeam Gaussian Beam Optics
AI agents call search_fiber_collimators to retrieve information from DiffBeam Gaussian Beam Optics without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
limit | integer | — | Maximum catalog matches to return. |
query | string | Yes | Part number or short component phrase. Use vendor-neutral physics terms unless the user names a vendor or part family. |
wavelength_nm | object | — | Optional operating wavelength in nanometres. |
focal_length_mm | object | — | Optional desired focal length in millimetres, used for ranking. |
Parameters from the server's own tool schema.
Why search_fiber_collimators is rated Low
Even though search_fiber_collimators only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
The rule that runs search_fiber_collimators safely
PolicyLayer is an MCP gateway: it sits between your AI agents and DiffBeam Gaussian Beam Optics, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For search_fiber_collimators, this is the rule to start with:
search_fiber_collimators is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect DiffBeam Gaussian Beam Optics, apply this rule, and every search_fiber_collimators call is checked against it from then on.
Questions about 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. It is categorised as a Read tool in the DiffBeam Gaussian Beam Optics MCP Server, which means it retrieves data without modifying state.
search_fiber_collimators accepts 4 parameters: limit, query, wavelength_nm, focal_length_mm. Required: query. The full parameter table on this page comes from the server's own tool schema.
Register the DiffBeam Gaussian Beam Optics MCP server in PolicyLayer and add a rule for search_fiber_collimators: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches DiffBeam Gaussian Beam Optics. Nothing to install.
search_fiber_collimators is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the search_fiber_collimators rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for search_fiber_collimators. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
search_fiber_collimators is provided by the DiffBeam Gaussian Beam Optics MCP server (https://catalog-api.gaussian-beam.com/mcp/). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
