What proj_close does on Eda Agent
AI agents use proj_close 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_close is rated Medium
Closing a project is a state-modification action rather than data retrieval (Read), code execution (Execute), or irreversible destruction (Destructive). It ranks above Read due to side effects. The severity is medium because closing a project in an EDA tool could interrupt ongoing work or automation workflows, but the action is reversible and does not destroy data or execute arbitrary commands.
From the tool's definition 'Close a project' modifies project state by terminating an open project, which is a reversible operation (the project can be reopened). This is a write action that changes application state without permanently destroying data.
Attacks that exploit this kind of access
The rule that runs proj_close 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_close, this is the rule to start with:
proj_close 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_close call is checked against it from then on.
Questions about proj_close
Close a project. 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_close: 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_close 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_close 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_close. 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_close 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.
