AI agents call litopys_get to retrieve information from Litopys without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool only retrieves node data from the graph-based memory system based on identifier lookup. 'Get' is a canonical read operation with no side effects. The 'optionally including incident edges' clause still only retrieves additional related data without modifying any state. This is consistent with the Read category pattern of query/fetch/get operations that do not alter the system.
From the tool's definition Tool name 'litopys_get' and description 'Get a node by id or alias, optionally including incident edges' directly indicate retrieval of existing data with no modification or deletion.
Attacks that exploit this kind of access
Get a node by id or alias, optionally including incident edges. It is categorised as a Read tool in the Litopys MCP Server, which means it retrieves data without modifying state.
Register the Litopys MCP server in PolicyLayer and add a rule for litopys_get: 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 Litopys. Nothing to install.
litopys_get 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 litopys_get 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 litopys_get. 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.
litopys_get is provided by the Litopys MCP server (litopys-dev/litopys). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
