WHAT IT DOES

What get_diffbeam_state does on DiffBeam Gaussian Beam Optics

AI agents call get_diffbeam_state 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
`known_server_revision`	object	—	Previously observed server revision, if any.
`known_catalog_revision`	object	—	Previously observed catalog revision, if any.
`known_tool_schema_revision`	object	—	Previously observed tool schema revision, if any.

Parameters from the server's own tool schema.

RISK

Why get_diffbeam_state is rated Low

Even though get_diffbeam_state 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

RECOMMENDED RULE

The rule that runs get_diffbeam_state 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 get_diffbeam_state, this is the rule to start with:

get_diffbeam_state Allowed

get_diffbeam_state is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_diffbeam_state": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect DiffBeam Gaussian Beam Optics, apply this rule, and every get_diffbeam_state call is checked against it from then on.

FAQ

Questions about get_diffbeam_state

What does the get_diffbeam_state tool do? +

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. It is categorised as a Read tool in the DiffBeam Gaussian Beam Optics MCP Server, which means it retrieves data without modifying state.

What parameters does get_diffbeam_state accept? +

get_diffbeam_state accepts 3 parameters: known_server_revision, known_catalog_revision, known_tool_schema_revision. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on get_diffbeam_state? +

Register the DiffBeam Gaussian Beam Optics MCP server in PolicyLayer and add a rule for get_diffbeam_state: 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.

What risk level is get_diffbeam_state? +

get_diffbeam_state is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit get_diffbeam_state? +

Yes. Add a rate_limit block to the get_diffbeam_state 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.

How do I block get_diffbeam_state completely? +

Set action: deny in the PolicyLayer policy for get_diffbeam_state. 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.

What MCP server provides get_diffbeam_state? +

get_diffbeam_state 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.
