Show non-secret 1Password CLI session state and runtime capability gates held by this MCP process.
AI agents call op_session_status 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 queries the current session state and runtime capabilities without side effects. It neither modifies data (Write), executes external operations (Execute), deletes anything (Destructive), nor involves financial transactions (Financial). The 'non-secret' qualifier further confirms it is purely informational.
From the tool's definition Tool description explicitly states 'Show non-secret 1Password CLI session state' — it retrieves session information without modifying or executing operations. The use of 'non-secret' and 'show' indicates a read-only query operation.

Show non-secret 1Password CLI session state and runtime capability gates held by this MCP process. 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 op_session_status: 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.
op_session_status 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 op_session_status 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 op_session_status. 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.
op_session_status 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.
