Why create_release needs a policy

Creating a release is a Write operation that generates a new versioned artifact. While technically reversible (a release can be deleted), it is typically treated as a significant, high-impact operation because releases trigger automated workflows, are consumed by downstream systems, and are often announced publicly.

From the tool's definition Tool name 'create_release' and description 'Create a new release for a repository' indicate irreversible creation of a release artifact in version control, which modifies repository state in a way that affects downstream systems (CI/CD pipelines, dependent…

POLICY

How to control create_release

PolicyLayer is an MCP gateway — it sits between your AI agents and Claude TypeScript MCP Servers, and nothing reaches the server without passing your rules. This is the rule we recommend for create_release:

policy.json

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

create_release 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.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about create_release

What does the create_release tool do? +

Create a new release for a repository. It is categorised as a Write tool in the Claude TypeScript MCP Servers MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_release? +

Register the Claude TypeScript MCP Servers MCP server in PolicyLayer and add a rule for create_release: 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 Claude TypeScript MCP Servers. Nothing to install.

What risk level is create_release? +

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

Can I rate-limit create_release? +

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

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

create_release is provided by the Claude TypeScript MCP Servers MCP server (ukkz/claude-ts-mcps). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Claude TypeScript MCP Servers tool call.

Start from Claude TypeScript MCP Servers, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
