Alibaba Cloud MaxCompute MCP Server

A local Model Context Protocol (MCP) launcher for Alibaba Cloud MaxCompute. It can run the original SDK-backed server (local mode) or act as a transparent stdio proxy to the hosted MaxCompute MCP service (remote mode).

[!IMPORTANT] MaxCompute Remote MCP Server is the recommended way to use MaxCompute MCP. Start with the hosted Remote MCP service documentation: MaxCompute MCP documentation.

This repository continues to host the local MCP server code for self-hosted and development scenarios. During the Remote MCP rollout, public, non-sensitive Remote MCP feedback is tracked through this repository's Remote MCP issue template.

Features

• Backward-compatible configuration: existing FE/Catalog endpoints determine Region and public/VPC network; simple region + network config derives FE, Catalog, and MCP endpoints without a Region registry.
• Transparent remote mode: stdio MCP messages are relayed to the hosted Streamable HTTP endpoint without rebuilding or renaming the remote tool surface.
• Current protocol support: MCP Python SDK 2.x preserves modern 2026-07-28 request metadata and routing headers while retaining legacy initialize compatibility.
• Standard CatalogAPI authentication: the remote proxy signs the bodyless mcpAccessToken operation with the existing credential provider and resolves current AK/STS/ECS RAM Role credentials again on renewal.
• Credential isolation: only a short-lived mcpc_ bearer is sent to the Gateway; AccessKey secrets and STS credentials never enter MCP messages or URLs, and a selected remote session never falls back to the local SDK.

Remote MCP Server (Recommended)

Use the hosted MaxCompute Remote MCP Server first unless you specifically need a local stdio or self-hosted setup. The remote service removes local runtime and credential setup from the MCP server process, uses Streamable HTTP, and follows the official Alibaba Cloud onboarding flow.

Remote MCP feedback

Use this repository's issues for public, non-sensitive Remote MCP feedback:

• Report Remote MCP feedback
• View existing issues

Include the MCP client name/version, endpoint type, tool name, request ID, time window with timezone, region, sanitized error code/message, expected behavior, actual behavior, and reproduction steps when available.

Do not include access tokens, refresh tokens, authorization codes, cookies, AccessKey IDs or secrets, OAuth callback URLs with query strings, sensitive SQL, customer data, or sensitive Logview content. Use official Alibaba Cloud support or security channels for account-specific permissions, billing, SLA-bound incidents, production outages, vulnerabilities, or confidential data cases.

Local launcher (optional)

The launcher defaults to default for upgrades from old configurations. It derives the Region and public/VPC network from the selected legacy FE and Catalog endpoints, or uses an explicit region plus network simple config. When this process uses stdio and Region/network can be determined, it obtains a CatalogAPI token and authenticates the one regional MCP endpoint with initialize. Token issuance or remote initialization failure falls back to the original local implementation. Use --mode local to pin that implementation.

Explicit remote mode is fail-closed: CatalogAPI issuance, MCP initialize, token renewal, or Gateway transport failures terminate the remote flow. default falls back only before selection. Once its authenticated initialize has selected remote, a later remote-session failure never invokes local SDK tools dynamically.

Requirements

The launcher needs:

• Python 3.10 or newer.
• uv for dependency management (recommended).
• The base installation supports the default remote proxy without PyODPS or PyArrow. Local SDK mode uses the optional local dependency set; its secure PyArrow wheel requires glibc 2.28+ or musl 1.2+ on Linux.
• Remote and local modes both need MaxCompute access through an AccessKey, STS credentials, a credentials URI, ECS RAM Role, or another supported default-credential-chain source.
• The remote proxy obtains a 300-second mcpc_ token through the standard signed CatalogAPI operation and stores no refresh token.
• MCP Python SDK 2.x is installed from the lockfile; modern 2026-07-28 and negotiated legacy stdio clients are both supported.

Installation

Install the released package from PyPI with either pip or uv:

python -m pip install alibabacloud-maxcompute-mcp-server
# or install the command in an isolated environment
uv tool install alibabacloud-maxcompute-mcp-server

The base package is intentionally remote-first and does not install PyODPS or PyArrow. Install the local SDK implementation only when it is needed:

python -m pip install "alibabacloud-maxcompute-mcp-server[local]"
# or
uv tool install "alibabacloud-maxcompute-mcp-server[local]"

With the base package, default still tries remote first. If remote initialization fails, the local fallback reports the command above instead of silently running without its SDK dependencies.

Verify the installed entry point:

alibabacloud-maxcompute-mcp-server --help

For source development, clone the repository and synchronize all development dependencies:

git clone https://github.com/aliyun/alibabacloud-maxcompute-mcp-server.git
cd alibabacloud-maxcompute-mcp-server
uv sync --all-extras

Run the development entry point:

uv run alibabacloud-maxcompute-mcp-server --help

Configuration

Runtime values use this precedence: command line, environment variables, JSON, then defaults. The mode is default when no source selects one.

The profile selects the endpoint, CatalogAPI client, and credentials used for token issuance in remote mode as well as the local SDK setup in local mode.

Copy the public example and fill in real values locally:

cp config.example.json config.json
# edit config.json with the real Region / network / project / credentials

config.json is git-ignored by default and must not be committed.

MaxCompute configuration fields

The simplest endpoint configuration is:

{
  "maxcompute": {
    "region": "cn-hangzhou",
    "network": "public",
    "defaultProject": "<DEFAULT_PROJECT_NAME>"
  }
}

region and network synthesize FE, Catalog, and MCP endpoints by rule. network: "vpc" uses intranet FE/Catalog endpoints and a VPC MCP endpoint.

Local-mode credential precedence

1. ALIBABA_CLOUD_ACCESS_KEY_ID / ALIBABA_CLOUD_ACCESS_KEY_SECRET environment variables (optionally with ALIBABA_CLOUD_SECURITY_TOKEN).
2. ALIBABA_CLOUD_CREDENTIALS_URI pointing to a local credential provider.
3. The Alibaba Cloud default credential chain (environment, file, ECS RAM role, etc.).
4. Static accessKeyId / accessKeySecret inside config.json (lowest priority, development only).

Environment-variable-only mode

You can skip the JSON file entirely and configure the server through environment variables:

Named local configs (runtime switching)

To switch between regions, endpoints, projects, or identities without restarting the MCP server, create a local multi-config file such as config.multi.json and point MAXCOMPUTE_CATALOG_CONFIG to it:

{
  "default": "beijing",
  "configs": {
    "beijing": {
      "region": "cn-beijing",
      "description": "Beijing production",
      "maxcompute_endpoint": "https://service.cn-beijing.maxcompute.aliyun.com/api",
      "accessKeyId": "<ALIBABA_CLOUD_ACCESS_KEY_ID>",
      "accessKeySecret": "<ALIBABA_CLOUD_ACCESS_KEY_SECRET>",
      "defaultProject": "<DEFAULT_PROJECT_NAME>",
      "namespaceId": "<ALIBABACLOUD_ACCOUNT_UID>"
    },
    "singapore": {
      "region": "ap-southeast-1",
      "description": "Singapore production",
      "maxcompute_endpoint": "https://service.ap-southeast-1.maxcompute.aliyun.com/api",
      "catalogapi_endpoint": "https://catalogapi.ap-southeast-1.maxcompute.aliyun.com",
      "protocol": "https",
      "accessKeyId": "<ALIBABA_CLOUD_ACCESS_KEY_ID>",
      "accessKeySecret": "<ALIBABA_CLOUD_ACCESS_KEY_SECRET>",
      "defaultProject": "<DEFAULT_PROJECT_NAME>",
      "namespaceId": "<ALIBABACLOUD_ACCOUNT_UID>"
    },
    "intl-readonly": {
      "region": "ap-southeast-1",
      "description": "Singapore readonly identity",
      "maxcompute_endpoint": "https://service.ap-southeast-1.maxcompute.aliyun.com/api",
      "catalogapi_endpoint": "https://catalogapi.ap-southeast-1.maxcompute.aliyun.com",
      "protocol": "https",
      "accessKeyId": "<READONLY_ALIBABA_CLOUD_ACCESS_KEY_ID>",
      "accessKeySecret": "<READONLY_ALIBABA_CLOUD_ACCESS_KEY_SECRET>",
      "defaultProject": "<READONLY_DEFAULT_PROJECT_NAME>",
      "namespaceId": "<ALIBABACLOUD_ACCOUNT_UID>"
    }
  }
}

The server starts with default (or the first config when default is omitted). In local mode, use the session tools list_configs, get_current_config, and use_config to inspect and switch the active config at runtime. These tools never return AccessKey IDs, AccessKey secrets, or STS tokens. Use --profile <name> or MAXCOMPUTE_MCP_PROFILE=<name> to select a config at startup in either mode.

Each named config must provide either maxcompute_endpoint or region plus network. If a legacy config omits catalogapi_endpoint, also provide defaultProject so the server can resolve the Catalog API endpoint through MaxCompute.

The active local config is process-global. Runtime switching is best suited to stdio / single-client usage. In shared Streamable HTTP mode, all connected clients share the same active config, so a use_config call from one client affects the others. Remote mode fixes one profile at startup and does not expose local session-switching tools.

Default selection and remote overrides

Released top-level maxcompute, top-level odps, named configs, and environment-only configurations all continue to load. Endpoint derivation has no Region list:

For legacy configuration, recognized FE and Catalog endpoints both contribute Region/network evidence. Public endpoints select public MCP; recognized VPC or intranet endpoints select VPC MCP. When both endpoints are recognized, they must identify the same Region and network. Conflicting endpoints never select remote, and explicit region/network values that contradict a recognized endpoint are rejected as invalid configuration.

A VPC configuration never selects public MCP or crosses Regions. Custom or historical endpoints with no verifiable Region/network, conflicting FE/Catalog evidence, or a local HTTP transport stay on legacy local behavior under default; explicit remote mode fails closed.

Endpoint naming is determined only by Region: Mainland China Regions (cn-*, except cn-hongkong) use mcp, while cn-hongkong and every other overseas Region use mcp-intl. This does not detect or distinguish account sites: the CatalogAPI-issued token path does not enter RAM OAuth. The derived endpoint is authenticated once during process startup and remains fixed for the process lifetime. Later CatalogAPI token renewal does not repeat initialization. When remote.url is explicitly configured, only that URL is used; VPC must still use the same Region.

A minimal remote override reuses the existing MaxCompute configuration and credentials:

{
  "mode": "remote",
  "remote": {
    "url": "https://mcp.cn-hangzhou.maxcompute.aliyun.com/mcp"
  },
  "maxcompute": {
    "region": "cn-hangzhou",
    "network": "public",
    "accessKeyId": "<ALIBABA_CLOUD_ACCESS_KEY_ID>",
    "accessKeySecret": "<ALIBABA_CLOUD_ACCESS_KEY_SECRET>"
  }
}

The remote URL must be an exact /mcp resource without userinfo, query, or fragment. The proxy rejects redirects, ignores ambient HTTP proxy variables, and renews the short-lived bearer through CatalogAPI single-flight. The CatalogAPI operation has no business body; scope and TTL are server-owned.

Running

Force local mode, stdio

uv run alibabacloud-maxcompute-mcp-server --mode local

Local mode, Streamable HTTP

uv run alibabacloud-maxcompute-mcp-server --transport http --host 127.0.0.1 --port 8000

Remote mode, stdio proxy

uv run alibabacloud-maxcompute-mcp-server --config /path/to/config.json

Derived regional endpoints need no site field under default. Add --mode remote --remote-url https://<REMOTE_MCP_HOST>/mcp only to override the default entry.

Remote mode rejects --transport http and --transport streamable-http.

MCP tools

Remote mode transparently exposes the tool list and contracts advertised by the selected Gateway. Local mode preserves the released SDK-backed tool surface. Local tools return JSON in an MCP text response; check success first, then read data, summary, or error.

Notes:

• execute_sql is read-only by design. The server validates SQL client-side and also submits jobs with the MaxCompute read-only hint.
• For SQL table references, call get_table_schema first and use the returned sqlTableRef; this handles two-level and three-level project naming.
• search_meta_data requires namespaceId / MAXCOMPUTE_NAMESPACE_ID.
• Large query results can be streamed to a local file:// output_uri; otherwise responses are returned inline and may be truncated.

For a rule-derived same-network regional endpoint, omit --mode and --remote-url and let default probe it. Do not put AccessKey IDs, secrets, STS tokens, or bearer tokens in MCP client arguments.

Streamable HTTP

This listener is available only in local mode. Start the server (see above), then point your MCP client at http://127.0.0.1:8000/mcp.
