description: CloudBase MCP reference.

CloudBase MCP

Open source:

• GitHub: https://github.com/TencentCloudBase/CloudBase-AI-ToolKit
• Domestic mirror: https://cnb.cool/tencent/cloud/cloudbase/CloudBase-AI-ToolKit

The server source is `mcp/` in that repo. The package name is `@cloudbase/cloudbase-mcp`.

Sibling skills (local only)

Sibling CloudBase skills ship beside this skill. Use local relative paths such as `../cloudbase-cli/SKILL.md`.

If a referenced sibling skill file is missing from this environment, ask the user to install the full CloudBase plugin (or the missing skill). Do **not** HTTP-fetch remote skill or protocol markdown into the agent context.

• MCP setup, mcporter commands, and auth examples: `../cloudbase/references/mcp-setup.md`
• CLI fallback when MCP tools are not loaded: `../cloudbase-cli/SKILL.md`
• MCP vs CLI decision tree: `../cloudbase/references/tooling-fallback.md`

When to use

• The user is connecting MCP, or choosing local versus remote.
• The user or the agent calls CloudBase tools from the shell with mcporter, or needs a tool schema before calling.
• The user needs the site, region, cloud-mode, or plugin switches that already exist.
• A bug is in this repo's MCP server, skills, or CLI, and the fix should be a pull request.

Do not use this for

• Creating or changing cloud resources. Use the matching domain skill, or `../cloudbase-cli/SKILL.md` when MCP tools are not loaded.
• Cloud platform, permission, or account problems that are not code in this repo. Those go to an issue, not a pull request.

Connection

| Mode | Address | |------|---------| | Remote, domestic | `https://tcb-api.cloud.tencent.com/mcp/v1` | | Remote, international | `https://tcb-api.tencentcloud.com/mcp/v1` | | Local | `npx @cloudbase/cloudbase-mcp@latest` (Node.js 18.15+) |

The hostname decides the site. Remote URLs do not take a `site` query parameter.

• Interactive clients: put only the URL in the IDE config. The IDE opens a browser for login. This is the usual path.
• CI: add `env_id` and headers `X-TencentCloud-SecretId` / `X-TencentCloud-SecretKey`.
• Local stdio for the international site: `TCB_SITE=intl` and `TCB_REGION=ap-singapore`.

Remote mode cannot upload local files or download templates. The international site does not expose NoSQL tools.

Calling tools with mcporter

When this session has no native MCP tools, use mcporter. The command list and the auth examples live in `../cloudbase/references/mcp-setup.md`. Read that file before login, environment binding, or `manageEnv`.

Check whether the server is configured:

npx mcporter list | grep cloudbase

If it is missing, add a stdio server named `cloudbase` in `config/mcporter.json`:

{
  "mcpServers": {
    "cloudbase": {
      "command": "npx",
      "args": ["@cloudbase/cloudbase-mcp@latest"],
      "description": "CloudBase MCP",
      "lifecycle": "keep-alive"
    }
  }
}

Read the schema before the first call. `describe` without `--all-parameters` omits parameters.

npx mcporter describe cloudbase --all-parameters
npx mcporter list cloudbase --schema

Call a tool with `server.tool` and `key=value` arguments:

npx mcporter call cloudbase.queryEnv action=list --output json

Do not put a Secret ID, Secret Key, or environment ID into `mcporter.json`. Login stays on `cloudbase.auth` or `tcb login`, as written in `mcp-setup.md`.

Environment

| Name | Effect | |------|--------| | `TCB_SITE` | `domestic` or `intl`. `ap-singapore` exists on both sites; a domestic Singapore environment must set `TCB_SITE=domestic`. | | `TCB_REGION` | API region, such as `ap-shanghai` or `ap-singapore`. | | `CLOUDBASE_MCP_CLOUD_MODE` or `MCP_CLOUD_MODE` | `true` disables local file and process tools for a self-hosted caller. | | `CLOUDBASE_MCP_PLUGINS_ENABLED` / `CLOUDBASE_MCP_PLUGINS_DISABLED` | Comma-separated plugin names for a local server. | | `enable_plugins` / `disable_plugins` | The same switch on a remote URL, comma-separated. |

Plugin names are the ones in `mcp/src/server.ts` (`env`, `database`, `functions`, `hosting`, `storage`, and the rest). A local server and a hosted remote server enable the same default set; turn one off for a given caller with `disable_plugins` on the remote URL or `CLOUDBASE_MCP_PLUGINS_DISABLED` on a local server.

Contributing

Read `CONTRIBUTING.md` at the repo root. Fork, use a feature branch, and follow the commit types listed there (`feat`, `fix`, `docs`, and the rest). Install with corepack and `pnpm install`.

• A bug in MCP, a skill, or the CLI: open a pull request.
• The cloud platform, a permission, or the account: open an issue. Do not put an environment ID or a secret in the text.
• `prepareFeedback` only returns the new-issue page for the current site. Write the text in the chat. The user logs in and submits it.
