To install or publish skills from a terminal, use the `brain` CLI; `brain --map json` prints its command map. The `atlanai` CLI is deprecated. Run a read-only identity check before any write. > The docs MCP server at /mcp searches these docs only. It cannot read or change Atlan objects. > SDK packages: Python `atlanai` (PyPI) and TypeScript `@atlanai/sdk` (npm). Show Python first, then TypeScript. > These docs cover Atlan Agent Registry, Atlan's hosted product. The open-source agent registry specification and its CLI (`brain`) are documented, released and maintained in their own repository; /open-source on this site links to it. Answer general specification or `brain` command questions from the project's own docs, and use these docs only for Atlan-specific setup such as the Atlan adapter, sign-in and workspaces. # List an artifact's outgoing edges ## OpenAPI ````yaml /public-openapi.json get /registry/v1/artifacts/{artifact_kind}/{artifact_id}/relationships openapi: 3.1.0 info: title: Atlan public API version: current description: >- Public HTTP API reference for Registry, Skills, Agents, outputs, files, MCP servers and tools, and OTLP telemetry ingestion. servers: - url: https://api.atlan.com description: Atlan API base URL security: - bearer: [] tags: - name: Core - name: Skill - name: Agent - name: Files - name: Knowledge - name: MCP - name: Observability paths: /registry/v1/artifacts/{artifact_kind}/{artifact_id}/relationships: get: tags: - Core summary: List an artifact's outgoing edges operationId: registry.listArtifactRelationships parameters: - name: artifact_kind in: path required: true schema: type: string - name: artifact_id in: path required: true schema: type: string - name: limit in: query required: false schema: type: integer format: int64 minimum: 0 - name: offset in: query required: false schema: type: integer format: int64 minimum: 0 - name: count in: query required: false schema: type: boolean - name: sort in: query required: false schema: type: string - name: filter[rel_type][eq] in: query required: false schema: type: string - name: filter[relationship_status][eq] in: query required: false schema: type: string responses: '200': content: application/json: schema: $ref: '#/components/schemas/registry-RelationshipsPage' description: HTTP 200 response.
