THE RISK

Medium Risk

Why github_deploy_config needs a policy

The tool generates configuration files for deployment platforms. This is a Write operation as it creates configuration files/artifacts. While it could trigger deployments (Execute), the description only mentions generating config, not executing a deployment. Misuse could lead to misconfigured deployments affecting production sites, hence medium severity.

From the tool's definition Generate deploy platform configuration (Vercel, Netlify, or Cloudflare Pages)

POLICY

How to control github_deploy_config

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_deploy_config:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "github_deploy_config": {
      "limits": [
        {
          "counter": "github_deploy_config_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

github_deploy_config 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.

Create a free account and register WP Astro MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about github_deploy_config

What does the github_deploy_config tool do? +

Generate deploy platform configuration (Vercel, Netlify, or Cloudflare Pages). It is categorised as a Write tool in the WP Astro MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on github_deploy_config? +

Register the WP Astro MCP server in PolicyLayer and add a rule for github_deploy_config: 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.

What risk level is github_deploy_config? +

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

Can I rate-limit github_deploy_config? +

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

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

github_deploy_config 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.

Enforce policy on every WP Astro MCP tool call.

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.
