List all canonical tag mappings.
AI agents call canonical_tag_list to retrieve information from Vector Task 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 and displays canonical tag mappings from the task management system. It is a read-only operation that has no impact on data integrity, does not execute code or commands, and does not delete or modify any information. The blast radius of misuse is minimal—an AI agent could at worst enumerate tags, which poses no security or operational risk.
From the tool's definition Tool name 'canonical_tag_list' and description 'List all canonical tag mappings' indicate a retrieval operation that queries existing data without modification or side effects.
Attacks that exploit this kind of access
List all canonical tag mappings. It is categorised as a Read tool in the Vector Task MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Vector Task MCP Server MCP server in PolicyLayer and add a rule for canonical_tag_list: 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 Vector Task MCP Server. Nothing to install.
canonical_tag_list 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 canonical_tag_list 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 canonical_tag_list. 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.
canonical_tag_list is provided by the Vector Task MCP Server MCP server (xsaven/vector-task-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
