A tool that searches for issues in Linear
AI agents call search_issues to retrieve information from MCP Linear App without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only search operation on existing issues. It queries data from Linear's project management system but does not create, modify, delete, or execute any actions. The blast radius of misuse is minimal—an AI agent could only retrieve information it's already authorized to access, with no capability to cause harmful side effects.
From the tool's definition Tool name 'search_issues' and description 'searches for issues in Linear' indicate a query operation with no side effects. Searching retrieves data without modifying, creating, or deleting any issues.
Attacks that exploit this kind of access
A tool that searches for issues in Linear. It is categorised as a Read tool in the MCP Linear App MCP Server, which means it retrieves data without modifying state.
Register the MCP Linear App 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 MCP Linear App. Nothing to install.
search_issues 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 search_issues 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 search_issues. 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.
search_issues is provided by the MCP Linear App MCP server (zalab-inc/mcp-linear-app). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
