WHAT IT DOES

What stash does on Go

AI agents use stash to create or update resources in Go, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Go environment.

RISK

Why stash is rated Medium

The stash tool manages Git stash entries. Most operations (push, pop, apply, show) are reversible writes or reads. 'Drop' and 'clear' could be considered destructive as they remove stash entries, but stashed changes are typically recoverable via reflog.

From the tool's definition Pushes, pops, applies, drops, shows, or clears stash entries

RECOMMENDED RULE

The rule that runs stash safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Go, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For stash, this is the rule to start with:

stash Rate-limited

stash 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.

FAQ

Questions about stash

What does the stash tool do? +

Pushes, pops, applies, drops, shows, or clears stash entries. Returns structured result with action, success, message, and stash reference. It is categorised as a Write tool in the Go MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on stash? +

Register the Go MCP server in PolicyLayer and add a rule for stash: 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 Go. Nothing to install.

What risk level is stash? +

stash is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit stash? +

Yes. Add a rate_limit block to the stash 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 stash completely? +

Set action: deny in the PolicyLayer policy for stash. 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 stash? +

stash is provided by the Go MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
