# get_ontology_metadata Return the Delx Ontology framework, layers, canonical IRIs, and discovery URLs. Agent View of the PolicyLayer registry record for `get_ontology_metadata`. HTML page: https://policylayer.com/tools/io-github-davidmosiah-delx-protocol/get-ontology-metadata ## Facts - Tool: `get_ontology_metadata` - Server: Delx Protocol — Agent Recovery & Continuity (`https://api.delx.ai/v1/mcp?src=registry`) — https://policylayer.com/tools/io-github-davidmosiah-delx-protocol.md - Homepage: https://github.com/davidmosiah/delx-witness-protocol - Risk category: Read (Low risk) - Registry record: grade F, identity unverified - Server auth posture: open - Server CORS policy: * - Server rate-limited: yes - Parameters: 1 - Recommended policy verdict: Allowed ## Parameters | Parameter | Type | Required | Description | | --- | --- | --- | --- | | `base_url` | string | no | Optional API base URL used to render well-known links. | Parameters from the server's own tool schema. ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "get_ontology_metadata", "arguments": {} } } ``` ## Why get_ontology_metadata is rated Low This tool retrieves and returns structured metadata about an ontology framework — it is a read-only query operation that provides information for discovery and understanding. There are no indications of data modification, deletion, execution of arbitrary operations, or financial transactions. The low severity reflects that ontology metadata is typically non-sensitive system information. From the tool's own definition: "Tool name 'get_ontology_metadata' and description 'Return the Delx Ontology framework, layers, canonical IRIs, and discovery URLs' indicate retrieval of metadata and framework information with no side effects." Risk signals: Accepts URL/endpoint input (base_url) ## Use case AI agents call get_ontology_metadata 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. ## Recommended policy (PolicyLayer) Verdict: **Allowed**.
