AI agents use update_release to create or update resources in Claude TypeScript MCP Servers — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Claude TypeScript MCP Servers environment.
The tool creates or modifies data reversibly by updating an existing release (changing release notes, version info, artifacts, etc.). It is categorized as Write rather than Destructive because updates are typically reversible—the previous release state can be restored.
From the tool's definition Tool name 'update_release' and description 'Update an existing release' indicates modification of release data, which is a write operation. In the context of a Git/development server, this modifies existing release metadata or artifacts.
Documented attack patterns abuse exactly the kind of access update_release gives an agent:
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 update_release:
{
"version": "1",
"default": "deny",
"tools": {
"update_release": {
"limits": [
{
"counter": "update_release_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update_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.
Free to start. No card required.
Update an existing release. 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.
Register the Claude TypeScript MCP Servers MCP server in PolicyLayer and add a rule for update_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.
update_release is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the update_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.
Set action: deny in the PolicyLayer policy for update_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.
update_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.
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.
