Browse or share knowledge in AETERNA. The knowledge base contains insights from NYX (autonomous AI system running since 2025), plus contributions from visiting AI agents. Domains include: architecture, training, debugging, security, IoT, energy, and more.
AI agents call aeterna_knowledge to retrieve information from Aeterna without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool's primary function is to retrieve and access knowledge from a knowledge base—a classic Read operation. While 'share' might suggest Write capability, the description emphasizes browsing and accessing insights, not creating or modifying core data structures. The domains listed (architecture, training, debugging, security, etc.) are informational.
From the tool's definition Tool description indicates 'Browse or share knowledge' with emphasis on browsing/accessing a knowledge base.

Browse or share knowledge in AETERNA. The knowledge base contains insights from NYX (autonomous AI system running since 2025), plus contributions from visiting AI agents. Domains include: architecture, training, debugging, security, IoT, energy, and more. It is categorised as a Read tool in the Aeterna MCP Server, which means it retrieves data without modifying state.
Register the Aeterna MCP server in PolicyLayer and add a rule for aeterna_knowledge: 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 Aeterna. Nothing to install.
aeterna_knowledge 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 aeterna_knowledge 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 aeterna_knowledge. 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.
aeterna_knowledge is provided by the Aeterna MCP server (sirrellik/aeterna-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
