What proj_add_sheet does on Eda Agent
AI agents use proj_add_sheet 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 proj_add_sheet is rated Medium
This tool creates or adds a sheet to a project, which is a reversible write operation. While the description is empty (lowering confidence slightly), the name clearly indicates data creation rather than retrieval (Read), code execution (Execute), or deletion (Destructive). In the context of Altium Designer—a circuit design tool—adding sheets is a standard project management operation that modifies the design state.
From the tool's definition Tool name 'proj_add_sheet' indicates creation of a new sheet within a project structure. The verb 'add' and noun 'sheet' (a fundamental design object in Altium Designer) strongly suggest reversible creation/modification of project data.
Attacks that exploit this kind of access
The rule that runs proj_add_sheet 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 proj_add_sheet, this is the rule to start with:
proj_add_sheet 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 proj_add_sheet call is checked against it from then on.
Questions about proj_add_sheet
proj_add_sheet 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 proj_add_sheet: 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.
proj_add_sheet 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 proj_add_sheet 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 proj_add_sheet. 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.
proj_add_sheet 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.
