search_issues

THE RISK

Low Risk

Why search_issues needs a policy

This is a read-only operation that queries GitHub for information about issues and pull requests. It has no side effects, cannot modify data, and poses minimal security risk. The blast radius of misuse is limited to unauthorized information disclosure about public/accessible GitHub issues.

From the tool's definition Tool name 'search_issues' and description 'Search for issues and pull requests across GitHub repositories' indicate a query/search operation that retrieves data without modifying or deleting anything.

POLICY

How to control search_issues

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 search_issues:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "search_issues": {}
  }
}

search_issues is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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

How do I enforce a policy on search_issues? +

Register the Claude TypeScript MCP Servers MCP server in PolicyLayer and add a rule for search_issues: 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 search_issues? +

What MCP server provides search_issues? +

search_issues 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.
