Read a Linear resource
AI agents call read-resource to retrieve information from Linear MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries data from Linear without side effects. The verb 'Read' and context of being part of an issue management system confirms it performs query operations only. No creation, modification, deletion, or external execution occurs. Low severity due to minimal blast radius—misuse would only expose queried data, not modify or damage resources.
From the tool's definition Tool name 'read-resource' combined with description 'Read a Linear resource' explicitly indicates data retrieval with no modification capability.
Attacks that exploit this kind of access
Read a Linear resource. It is categorised as a Read tool in the Linear MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Linear MCP Server MCP server in PolicyLayer and add a rule for read-resource: 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 Linear MCP Server. Nothing to install.
read-resource 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 read-resource 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 read-resource. 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.
read-resource is provided by the Linear MCP Server MCP server (iwark/linear-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
