プラグインの作成

$ ant beta:organization:plugins create
POST/v1/organizations/plugins

バージョンのファイルをアップロードして、組織所有のプラグインとその最初のバージョンを作成します。

アップロードは multipart/form-data 形式です。バージョンのファイル(files、各パートは files[] として送信)と、任意の marketplace_id および release_notes を含めます。マニフェストの name が プラグインの name になり、display_name、description、manifest_version も マニフェストから取得されます。

name には小文字(任意のアルファベット)、数字、ハイフンを最大64文字まで使用できます。 大文字、スペース、アンダースコア、その他の句読点は拒否されます。

name はマーケットプレイス内で一意である必要があります。すでに使用されている名前の場合は、 error_code が plugin_name_taken の409が返され、その名前をプラグインが保持している場合は、 そのプラグインのIDが details.plugin_id に含まれます。組織のライブラリマーケットプレイスに 追加されるプラグインは、そのスキルのいずれかが組織スキル(管理者がclaude.aiで組織全体向けに アップロードしたスキル)と同じ名前を持つ場合にも409で拒否されます。この場合、error_code は skill_name_taken で、その名前が details.skill_name に含まれます。スキルの名前を変更するか、 claude.aiで組織スキルを削除してください。error_code が registration_pending の503は、プラグインとそのバージョンは保存された(それらのIDは details に含まれます)ものの、まだclaude.aiで使用できないことを意味します。作成を再試行しないでください (再試行すると plugin_name_taken が返されます)。代わりに、保存されたプラグインでバージョンを作成すると、 作成が完了します。

具体例については、Plugins APIガイドのプラグインの作成を 参照してください。

使用可能な認証情報: write:plugins スコープを持つAdmin APIキー。

すべてのリクエストにベータヘッダー anthropic-beta: ce-plugins-2026-09-01 を含める必要があります。このヘッダーがないリクエストは、エンドポイントが存在しない場合とまったく同じように 404 を返します。Plugins APIはベータ版で、Claude Enterpriseの組織のみが利用できます。Claude Platform(Claude Console)の組織や、HIPAA対応が有効になっている組織では利用できません。

Parameters
--file: array of string

The version's files: one part per file, the part's filename being the file's path within the Plugin (for example skills/review-pr/SKILL.md), or a single .zip or .plugin archive holding them all. On the wire each part is named files[], and a part named plain files is not read; with cURL, -F 'files[]=@SKILL.md;filename=skills/review-pr/SKILL.md'. The files must include the manifest, .claude-plugin/plugin.json.

--marketplace-id: optional string

ID of the organization-owned plugin marketplace to create the Plugin in (prefixed marketplace_). It must be a manual marketplace, one whose Plugins are uploaded rather than synchronized from a repository. When omitted, the Plugin is created in the organization's library marketplace, an organization-owned manual marketplace created on first use.

--release-notes: optional string

Release notes stored with the version and shown in its version history in claude.ai; up to 5,000 characters.

maxLength5000
--beta: optional array of AnthropicBeta⁠Header parameter

This endpoint is in beta: requests must send ce-plugins-2026-09-01 in this header.

Returns
beta_plugin: object{ type: "plugin", id, components, 16 more }
type: "plugin"

Always plugin.

id: string

The Plugin's ID.

components: array of BetaPluginComponent { type, description, name }

What the served version contains; null when not enumerated.

type: "agent" or "cli" or "command" or 3 more

The kind of component.

One of the following:
"agent"
"cli"
"command"
"hook"
"mcp_server"
"skill"
description: string

What the component declares about itself; always null for MCP servers, hooks, and CLIs.

name: string

The component's name: a skill's, command's or agent's name, an MCP server's key in the manifest, the event a hook runs on, or a CLI's executable.

content_scan: object{ assessment, reason, status }

The served version's content scan; null when it has not been scanned.

assessment: "fail" or "pass" or "unknown" or "warn"

The scan's verdict; set only when status is completed.

One of the following:
"fail"
"pass"
"unknown"
"warn"
reason: string

The primary mechanism behind a warn or fail, such as credential-exposure or guardrail-tampering; a mechanism this API does not yet name reads as other. Null on a pass, whenever assessment is null, and when no mechanism is reported for the verdict.

status: "completed" or "errored" or "processing"

processing while a scan runs, completed when it ran to completion, errored when it could not run or its outcome cannot be read.

One of the following:
"completed"
"errored"
"processing"
created_at: string

RFC 3339.

formatdate-time
created_by: BetaPluginUserActor or BetaPluginAPIActor

Who created the Plugin; null when no creator is recorded.

One of the following:
beta_plugin_user_actor: object{ type: "user_actor", email_address, user_id }
type: "user_actor"

A member of the organization.

email_address: string

The member's email address; may be null, for example when they are no longer a member of the organization.

user_id: string

The member's User ID.

beta_plugin_api_actor: object{ type: "api_actor", api_key_id }
type: "api_actor"

An Admin API key, in the same form the Compliance API activity feed uses for it.

api_key_id: string

The key's ID.

description: string

The served version's description.

display_name: string

The served version's display name.

latest_version_id: string

The newest version.

manifest_version: string

The served version's manifest version, normalized for display, or null (the Plugin Version's manifest_version says how and when).

marketplace_id: string

The ID of the plugin marketplace the Plugin lives in.

name: string

Lowercase identifier, unique within its plugin marketplace. Fixed for an organization-owned Plugin's lifetime; a member-owned Plugin's changes when its owner renames it in claude.ai, while its id stays the same.

organization_installation_preference: "auto_install" or "available" or "not_available" or "required"

Organization-owned Plugin: the organization-wide installation setting every member gets unless an RBAC Group they belong to holds its own — the Plugin's own setting, or its plugin marketplace's default. Null for a member-owned Plugin, which has shares instead. One of required, auto_install, available, not_available; a value this API does not yet name is returned as stored.

One of the following:
"auto_install"
"available"
"not_available"
"required"
organization_installation_preference_inherited: boolean

Organization-owned Plugin: true while it has no organization-wide setting of its own and organization_installation_preference is its plugin marketplace's default. Null for a member-owned Plugin.

owner: BetaPluginOwnerOrganization or BetaPluginOwnerUser

Who owns the Plugin: the organization, or the member whose personal plugin marketplace it lives in.

One of the following:
beta_plugin_owner_organization: object{ type: "organization" }
type: "organization"

The Plugin lives in a plugin marketplace the organization owns.

beta_plugin_owner_user: object{ type: "user", user_id }
type: "user"

The Plugin lives in one member's personal plugin marketplace.

user_id: string

The member's User ID.

reach: "contained" or "privileged" or "remote"

How far the served version reaches, or null if it is not classified.

remote means it declares an MCP server or a CLI. privileged means it declares no MCP server or CLI, but declares a hook, monitor, language server, or settings, or has a skill, command, or other Markdown file whose frontmatter pre-approves tools (allowed-tools with any value other than an empty one or one that names only AskUserQuestion, TodoWrite, and ToolSearch). Otherwise it is contained.

If the frontmatter of a skill, command, or other Markdown file that could change the value could not be read, or was past a size limit, the version is null or privileged (or remote, if it declares an MCP server or a CLI), not contained. The value is normally worked out when a version is stored, under the rules of that time, so an older version can be null, or contained where the same files stored today would be privileged or null.

One of the following:
"contained"
"privileged"
"remote"
served_version_id: string

The version claude.ai serves to members.

served_version_pinned: boolean

False while the served version follows each new version; true once it has been pinned to one.

updated_at: string

RFC 3339. Moves on a new version and on a served-version change; a change to the Plugin's installation settings or shares does not move it.
