List all access codes, optionally filtered by device
AI agents call list_access_codes to retrieve information from Seam 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 queries existing access codes without creating, modifying, deleting, or executing any lock operations. It is a passive data retrieval operation similar to the sibling 'list_locks' and 'get_lock_status' tools. While it provides information about access credentials, the tool itself performs no side effects or irreversible actions.
From the tool's definition Tool name 'list_access_codes' and description 'List all access codes, optionally filtered by device' indicate a query/retrieval operation with no modification or execution of lock control actions.
Attacks that exploit this kind of access
List all access codes, optionally filtered by device. It is categorised as a Read tool in the Seam MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Seam MCP Server MCP server in PolicyLayer and add a rule for list_access_codes: 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 Seam MCP Server. Nothing to install.
list_access_codes 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_access_codes 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_access_codes. 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_access_codes is provided by the Seam MCP Server MCP server (keithah/seam-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
