Devuelve un resumen compacto de todas las memorias agrupado por categoría. Ideal para cargar contexto al inicio de una sesión con el mínimo de tokens. Incluye: total de memorias, conteo por categoría con las N más recientes, e índice de frecuencia de tags.
AI agents call get_context_snapshot to retrieve information from Engram without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and summarizes existing data from the memory store without side effects. It performs read-only operations (counting, filtering, summarizing) on stored memories. The description indicates it is designed for loading context at session start, which is a passive data retrieval use case. No data is created, modified, deleted, or executed.
From the tool's definition Tool name 'get_context_snapshot' and description 'returns a compact summary of all memories grouped by category' with 'total memories, count by category with N most recent, and tag frequency index' — purely retrieval operations with no modification, deletion,…

Devuelve un resumen compacto de todas las memorias agrupado por categoría. Ideal para cargar contexto al inicio de una sesión con el mínimo de tokens. Incluye: total de memorias, conteo por categoría con las N más recientes, e índice de frecuencia de tags. It is categorised as a Read tool in the Engram MCP Server, which means it retrieves data without modifying state.
Register the Engram MCP server in PolicyLayer and add a rule for get_context_snapshot: 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 Engram. Nothing to install.
get_context_snapshot 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_context_snapshot 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_context_snapshot. 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_context_snapshot is provided by the Engram MCP server (jacksini/engram-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
