List all collections in the Directus instance. Returns collection names, metadata, and schema information.
AI agents call list_collections to retrieve information from Directus 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 straightforward query operation that retrieves and lists existing collections and their metadata. It does not create, modify, delete, or execute any operations—only reads and returns information. The severity is low because exposure of this information alone does not enable destructive or financial actions; it is purely informational about the instance structure.
From the tool's definition Tool name 'list_collections' and description 'List all collections in the Directus instance. Returns collection names, metadata, and schema information.' indicate a retrieval-only operation with no side effects.
Attacks that exploit this kind of access
List all collections in the Directus instance. Returns collection names, metadata, and schema information. It is categorised as a Read tool in the Directus MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Directus MCP Server MCP server in PolicyLayer and add a rule for list_collections: 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 Directus MCP Server. Nothing to install.
list_collections 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_collections 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_collections. 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_collections is provided by the Directus MCP Server MCP server (skeyelab/directus-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
