What gh_run does on Yaver

AI agents invoke gh_run to trigger actions in Yaver. 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.

ParameterTypeRequiredDescription
args array Yes subcommand + flags, e.g. ["repo", "view", "--json", "description"]
directory string Working directory; defaults to agent cwd

Parameters from the server's own tool schema.

Why gh_run needs a policy

gh_run triggers real processes with real consequences. An agent gone sideways doesn't fire it once — it starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

Risk signalsAccepts file system path (directory)

Questions about gh_run

What does the gh_run tool do? +

Run any gh (GitHub CLI) subcommand. Pass the args as a list (no leading gh). Pre-flights install + auth state, returns a clear error when the CLI is missing or unauthed. Use this for anything not covered by the specific github_* tools (e.g. gh repo create, gh release create, gh secret set). It is categorised as a Execute tool in the Yaver MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

What parameters does gh_run accept? +

gh_run accepts 2 parameters: args, directory. Required: args. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on gh_run? +

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

What risk level is gh_run? +

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

Can I rate-limit gh_run? +

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

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

gh_run is provided by the Yaver MCP server (yaver-cli). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
