What sch_increment_designators does on Eda Agent
AI agents use sch_increment_designators to create or update resources in Eda Agent, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Eda Agent environment.
Why sch_increment_designators is rated Medium
This tool creates or modifies designators in a schematic reversibly—designators can be re-incremented or manually corrected. It affects design metadata rather than destructively removing data. The empty description limits confidence, but the name strongly suggests a Write operation (update/modify).
From the tool's definition Tool name 'sch_increment_designators' indicates it modifies schematic designators (component reference designators like R1, C2, U3, etc.). The verb 'increment' implies numeric modification of existing values.
Attacks that exploit this kind of access
The rule that runs sch_increment_designators safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Eda Agent, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For sch_increment_designators, this is the rule to start with:
sch_increment_designators stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Eda Agent, apply this rule, and every sch_increment_designators call is checked against it from then on.
Questions about sch_increment_designators
sch_increment_designators is a write tool on the Eda Agent MCP server. It is categorised as a Write tool in the Eda Agent MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Eda Agent MCP server in PolicyLayer and add a rule for sch_increment_designators: 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 Eda Agent. Nothing to install.
sch_increment_designators is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the sch_increment_designators 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 sch_increment_designators. 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.
sch_increment_designators is provided by the Eda Agent MCP server (salitronic/eda-agent). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
