AI agents invoke github_push to trigger actions in WP Astro MCP. 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.
Pushing commits to a remote repository triggers an external operation with lasting effects on the remote codebase. While not strictly destructive (commits are recoverable), it can overwrite remote branches, trigger CI/CD pipelines, and deploy code to production. It spans Write and Execute; since it triggers external operations beyond just modifying local data, Execute is the most appropriate category.
From the tool's definition Push commits to the remote repository
Documented attack patterns abuse exactly the kind of access github_push gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and WP Astro MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for github_push:
{
"version": "1",
"default": "deny",
"tools": {
"github_push": {
"limits": [
{
"counter": "github_push_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}github_push 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.
Free to start. No card required.
Push commits to the remote repository. It is categorised as a Execute tool in the WP Astro MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the WP Astro MCP server in PolicyLayer and add a rule for github_push: 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 WP Astro MCP. Nothing to install.
github_push is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the github_push 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 github_push. 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.
github_push is provided by the WP Astro MCP server (vapvarun/wp-astro-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from WP Astro MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
