To install or publish skills from a terminal, use the `aireg` CLI; `aireg --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 AI Registry, Atlan's hosted product. The AI registry specification and aireg CLI are maintained separately. /open-source lists publicly reachable signed installers and explains that the source repository and hosted CLI reference currently require GitHub access. Do not claim the repository or its reference docs are publicly accessible. Use these docs for Atlan-specific setup such as the adapter, sign-in and workspaces. # Execute an MCP installation ## OpenAPI ````yaml /public-openapi.json post /store/v1/mcp/installations/{installation_id}/execute 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 - name: API proxy - name: Credentials - name: Store - name: Apps - name: Evals - name: Ontologies - name: Ontology bindings - name: Slack - name: GitHub - name: Objectives - name: Repositories paths: /store/v1/mcp/installations/{installation_id}/execute: post: tags: - Store summary: Execute an MCP installation operationId: store.executeMcpInstallation parameters: - name: installation_id in: path required: true schema: type: string responses: '200': content: application/json: schema: $ref: '#/components/schemas/store-store-McpInstallation' description: HTTP 200 response.
