MCP servers are account-wide rather than per-user, so every caller authenticated for the account sees the same set. Deactivated servers are included, with isActive reporting their state. top is silently clamped to the range 1-100 and a negative offset is treated as 0. ## OpenAPI ````yaml /api-reference/openapi.json get /v1/mcpservers openapi: 3.0.0 info: title: Engini DeveloperAPI version: v1 description: 'Merged public developer API spec: Identity + WorkflowApi.' servers: - url: https://api.engini.io security: - Bearer: [] - ApiKey: [] tags: - name: Auth description: Identify the caller a Developer API request is authenticated as. - name: Applications description: >- Discover the applications (toolkits) available in Engini and their connection requirements. - name: Tools description: Browse and execute the tools exposed by Engini applications. - name: Toolsets description: Manage toolsets - named groupings of connections and tools. - name: McpServers description: >- Inspect and maintain MCP servers - the account-wide endpoints that expose Engini tools and workflows over the Model Context Protocol.
