What obj_create does on Eda Agent
AI agents use obj_create 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 obj_create is rated Medium
The tool name 'obj_create' suggests creating design objects (schematic components, PCB elements, library items) within Altium Designer. This is a Write operation—reversible creation of project data. Confidence is moderate (0.70) because the empty description prevents full certainty; however, 'create' is semantically clear in a design automation context.
From the tool's definition Tool name 'obj_create' combined with server context showing '290+ tools for schematic, PCB, library & project automation' indicates object creation capability. Description is empty, limiting specificity.
Attacks that exploit this kind of access
The rule that runs obj_create 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 obj_create, this is the rule to start with:
obj_create 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 obj_create call is checked against it from then on.
Questions about obj_create
obj_create 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 obj_create: 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.
obj_create 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 obj_create 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 obj_create. 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.
obj_create 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.
