Fetch an AnchorID (canonical entity) by UUID. Optionally include linked
AI agents call get_entity to retrieve information from Anchord MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves/queries entity data by UUID without side effects. It is purely informational—fetching a canonical entity record and optionally viewing linked records does not create, modify, delete, or execute external operations. The 'Fetch' verb confirms read-only semantics. Severity is low because unauthorized access would expose metadata but not enable mutations or financial impact.
From the tool's definition Tool name 'get_entity' and description 'Fetch an AnchorID (canonical entity) by UUID' indicate a retrieval operation with no modification of data.
Attacks that exploit this kind of access
Fetch an AnchorID (canonical entity) by UUID. Optionally include linked. It is categorised as a Read tool in the Anchord MCP MCP Server, which means it retrieves data without modifying state.
Register the Anchord MCP server in PolicyLayer and add a rule for get_entity: 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 Anchord MCP. Nothing to install.
get_entity 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 get_entity 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 get_entity. 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.
get_entity is provided by the Anchord MCP server (nolenation04/anchord-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
