la_capture · Logic Analyzer MCP: Risk & Policy

WHAT IT DOES

What la_capture does on Logic Analyzer

AI agents invoke la_capture to trigger actions in Logic Analyzer. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why la_capture needs a policy

Based on the server context, la_capture likely initiates a hardware capture session on a USB logic analyzer, triggering an external hardware operation. This falls under Execute as it triggers an external operation. Confidence is reduced due to the empty description.

From the tool's definition Tool name 'la_capture' on a logic analyzer server described as capturing digital traces; description is empty/uninformative.

Verdict

la_capture Rate-limited

la_capture stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Logic Analyzer, so you can run agents against it safely.

FAQ

Questions about la_capture

What does the la_capture tool do? +

la_capture. It is categorised as a Execute tool in the Logic Analyzer MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on la_capture? +

Register the Logic Analyzer MCP server in PolicyLayer and add a rule for la_capture: 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 Logic Analyzer. Nothing to install.

What risk level is la_capture? +

la_capture is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit la_capture? +

Yes. Add a rate_limit block to the la_capture 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 la_capture completely? +

Set action: deny in the PolicyLayer policy for la_capture. 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 la_capture? +

la_capture is provided by the Logic Analyzer MCP server (sandraschi/logic-analyzer-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
