A connection allows a custom name. A plugin of an organization cannot share its name with another plugin of that organization or with a tenant-wide plugin, and a tenant-wide plugin cannot share it with any plugin of the tenant, ignoring case (409 otherwise). Every new plugin, a legacy one included, starts enabled unless enabled is false. A bearer or API key connection sends one Secret or Vault path credential of the plugin organization or tenant-wide, named in authentication.credential_id; without one the plugin is saved only with enabled false, and 400 otherwise. For a token per agent, use an anonymous plugin and the accessible credentials of the agent; for two authentication methods, create two plugins. Legacy creation keeps its supported names. A hosted MCP server (transport stdio) is a container image the engine starts, with its arguments and environment variables, each a plain value or a Secret or Vault path credential; adding one takes a tenant-level administrator (403 otherwise). ## OpenAPI ````yaml /0.17/openapi.json post /api/v1/plugins openapi: 3.0.3 info: title: 2501 Public API version: v1 description: >- The stable, versioned HTTP API for driving 2501 as code.
