WHAT IT DOES

What app_attach does on Eda Agent

AI agents invoke app_attach to trigger actions in Eda Agent. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why app_attach is rated High

This tool initiates a connection to an external application (Altium Designer), which is an external operation that establishes a persistent bridge. It doesn't merely read data or write data reversibly — it triggers an external system interaction (attaching to a running process). Misuse could enable subsequent unauthorized operations on design files.

RECOMMENDED RULE

The rule that runs app_attach 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 app_attach, this is the rule to start with:

app_attach Rate-limited

app_attach stays usable, but rate-capped: a runaway agent can't fire it dozens of times 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 app_attach call is checked against it from then on.

FAQ

Questions about app_attach

What does the app_attach tool do? +

Connect to a running Altium Designer instance. It is categorised as a Execute tool in the Eda Agent MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on app_attach? +

Register the Eda Agent MCP server in PolicyLayer and add a rule for app_attach: 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.

What risk level is app_attach? +

app_attach is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit app_attach? +

Yes. Add a rate_limit block to the app_attach 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.

How do I block app_attach completely? +

Set action: deny in the PolicyLayer policy for app_attach. 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.

What MCP server provides app_attach? +

app_attach 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.
