get_aspects
AI agents call get_aspects to retrieve information from Kerykeion MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Based on naming convention and server context, 'get_aspects' most likely retrieves astrological aspect data (angular relationships between celestial bodies). The 'get_' prefix conventionally indicates read-only data retrieval.
From the tool's definition Tool name 'get_aspects' with no description provided; sibling tools on this server include 'generate_*_chart' and 'get_current_positions', establishing a pattern where 'get_' prefix retrieves astrological data without side effects.

Register the Kerykeion MCP Server MCP server in PolicyLayer and add a rule for get_aspects: 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 Kerykeion MCP Server. Nothing to install.
get_aspects 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_aspects 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_aspects. 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_aspects is provided by the Kerykeion MCP Server MCP server (jasperb3/kerykeion-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
