Get item metadata with every field value redacted. Use secret_reveal only when plaintext is explicitly required.
AI agents call item_get_metadata to retrieve information from Mcp 1password without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata without side effects. Although it accesses secrets management infrastructure, it returns redacted data and does not modify, delete, execute, or move resources. The severity is low because even in misuse, the redaction-by-default design limits exposure. Confidence is high due to clear descriptive language indicating read-only retrieval.
From the tool's definition Tool name 'item_get_metadata' and description states it retrieves item metadata with values redacted by default. No creation, modification, deletion, or execution occurs.

Attacks that exploit this kind of access
Get item metadata with every field value redacted. Use secret_reveal only when plaintext is explicitly required. It is categorised as a Read tool in the Mcp 1password MCP Server, which means it retrieves data without modifying state.
Register the Mcp 1password MCP server in PolicyLayer and add a rule for item_get_metadata: 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 1password. Nothing to install.
item_get_metadata 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 item_get_metadata 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 item_get_metadata. 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.
item_get_metadata is provided by the Mcp 1password MCP server (kefapps/onepassword-mcp-codex). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
