What proj_annotate does on Eda Agent
AI agents use proj_annotate 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_annotate is rated Medium
The 'annotate' action typically means adding notes, comments, or metadata to existing objects—a reversible modification. Given Altium Designer's project-centric model and the tool's position among design automation utilities, it most likely writes annotation data to project/design elements.
From the tool's definition Tool name 'proj_annotate' suggests adding or modifying annotations within a project context. Combined with the server's focus on design automation for Altium Designer, this likely creates or modifies metadata/annotations in design projects, which is…
Attacks that exploit this kind of access
The rule that runs proj_annotate 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_annotate, this is the rule to start with:
proj_annotate 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_annotate call is checked against it from then on.
Questions about proj_annotate
proj_annotate 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_annotate: 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_annotate 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_annotate 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_annotate. 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_annotate 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.
