AI agents call searchIssues to retrieve information from Backlog MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a search query to retrieve issue data from a project management system. It has no side effects—it only reads and returns existing data. While searchable APIs can expose sensitive information depending on access controls, the tool itself is fundamentally a Read operation.
From the tool's definition Tool name 'searchIssues' and description 'Backlogの課題を検索します' (searches Backlog issues) indicates a retrieval operation with no data modification capability.
Documented attack patterns abuse exactly the kind of access searchIssues gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Backlog MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for searchIssues:
{
"version": "1",
"default": "deny",
"tools": {
"searchIssues": {}
}
}searchIssues is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Backlogの課題を検索します. It is categorised as a Read tool in the Backlog MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Backlog MCP Server MCP server in PolicyLayer and add a rule for searchIssues: 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 Backlog MCP Server. Nothing to install.
searchIssues is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the searchIssues 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 searchIssues. 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.
searchIssues is provided by the Backlog MCP Server MCP server (jootsuki/backlog-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Backlog MCP Server, 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.
