What list_ontology_primitives does on Delx Protocol — Agent Recovery & Continuity
AI agents call list_ontology_primitives to retrieve information from Delx Protocol — Agent Recovery & Continuity without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
layer | string | — | Optional layer id filter. |
Parameters from the server's own tool schema.
Why list_ontology_primitives is rated Low
This tool retrieves and queries ontology structure to enable agent discovery. It has no side effects, cannot modify data, execute operations, or cause harm. It is a pure Read operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool name contains 'list' and description states 'List ontology primitives' — a discovery/enumeration operation.
Attacks that exploit this kind of access
The rule that runs list_ontology_primitives safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Delx Protocol — Agent Recovery & Continuity, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_ontology_primitives, this is the rule to start with:
list_ontology_primitives is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Delx Protocol — Agent Recovery & Continuity, apply this rule, and every list_ontology_primitives call is checked against it from then on.
Questions about list_ontology_primitives
List ontology primitives and their layers so agents can discover what can be witnessed, related, or carried forward. It is categorised as a Read tool in the Delx Protocol — Agent Recovery & Continuity MCP Server, which means it retrieves data without modifying state.
list_ontology_primitives accepts 1 parameter: layer. The full parameter table on this page comes from the server's own tool schema.
Register the Delx Protocol — Agent Recovery & Continuity MCP server in PolicyLayer and add a rule for list_ontology_primitives: 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 Delx Protocol — Agent Recovery & Continuity. Nothing to install.
list_ontology_primitives 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 list_ontology_primitives 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 list_ontology_primitives. 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.
list_ontology_primitives is provided by the Delx Protocol — Agent Recovery & Continuity MCP server (https://api.delx.ai/v1/mcp?src=registry). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
