AI agents call list_tags to retrieve information from Codecks 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 operation that retrieves existing project tags. It has no capability to create, modify, delete, or execute any actions. The blast radius of misuse is minimal—an agent could only obtain information about available tags in the project.
From the tool's definition Tool name is 'list_tags' and description states 'List project-level tags (sanctioned taxonomy)' — it queries and retrieves tag data with no modification or side effects.
Attacks that exploit this kind of access
List project-level tags (sanctioned taxonomy). It is categorised as a Read tool in the Codecks MCP Server, which means it retrieves data without modifying state.
Register the Codecks MCP server in PolicyLayer and add a rule for list_tags: 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 Codecks. Nothing to install.
list_tags 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 list_tags 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 list_tags. 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.
list_tags is provided by the Codecks MCP server (rangogamedev/codecks-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
