Get specific variable values for a polity over time.
AI agents call get_variables to retrieve information from Seshat 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 historical data from the Seshat Global History Databank without creating, modifying, or deleting anything. The verb 'get' and the read-only nature of querying immutable historical records place it firmly in the Read category with minimal security risk.

Register the Seshat MCP Server MCP server in PolicyLayer and add a rule for get_variables: 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 Seshat MCP Server. Nothing to install.
get_variables 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_variables 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_variables. 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_variables is provided by the Seshat MCP Server MCP server (mosse/seshat-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
get_variables is one line of Seshat MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
