Asset MCP

中文文档

Read-only Python MCP server for aggregating personal assets across Binance, OKX, moomoo OpenD, Longbridge, IBKR, on-chain wallets, and manually configured accounts.

The server exposes normalized asset data to any MCP-compatible AI client. It does not trade, transfer, withdraw, or automate bank/Alipay access.

Features

• Multiple Binance accounts.
• Multiple OKX accounts.
• Multiple moomoo/Futu OpenD accounts.
• Multiple Longbridge OpenAPI accounts.
• Multiple IBKR Flex Web Service accounts.
• On-chain wallet addresses for BTC, ETH, SOL, BSC, TRON, Polygon, Avalanche,

Arbitrum, Base, and Optimism.

• Manual assets for banks, Alipay, cash, property, and other offline accounts.
• USD-denominated net worth summaries.
• Dashboard-ready grouped data for AI-generated charts.

Requirements

• Python >=3.10.
• Read-only Binance/OKX API keys if enabling exchange accounts.
• moomoo/Futu OpenD installed, running, and logged in if enabling moomoo

accounts.

• Longbridge OpenAPI API key credentials if enabling Longbridge accounts.
• IBKR Flex Web Service token and Flex Query ID if enabling IBKR accounts.
• Public wallet addresses if enabling on-chain wallet accounts.
• uv is only required for local development; end users can install with

pip.

Quick Start

# 1. Install from PyPI
pip install asset-mcp

# 2. Create the starter config (~/.config/asset-mcp/config.local.yaml)
asset-mcp init

# 3. Edit the config: fill in credentials for at least one account
#    and set its `enabled: true`. See "Configure" below for per-provider examples.
vim ~/.config/asset-mcp/config.local.yaml

# 4. Register the server with your MCP client
claude mcp add asset-mcp -- asset-mcp
# or
codex mcp add asset-mcp -- asset-mcp

# 5. Verify: ask your client to call the `health_check_sources` tool.
#    Every enabled account should return `ok: true`.

The smallest working setup needs no API keys — a single manual cash account is enough to confirm the install:

baseCurrency: USD
rates:
  USD: 1.0
  CNY: 0.14
manual:
  accounts:
    - id: cash
      label: Cash on hand
      enabled: true
      category: cash
      assets:
        - symbol: CNY
          quantity: 10000
          currency: CNY

Install

Install from PyPI:

pip install asset-mcp

The base installation works with Binance, OKX, IBKR, on-chain wallets, and manual accounts. The moomoo and Longbridge SDKs are optional extras — install them only when needed:

pip install "asset-mcp[moomoo]"
pip install "asset-mcp[longbridge]"
pip install "asset-mcp[moomoo,longbridge]"

Existing config files are never overwritten by asset-mcp init unless you pass --force:

asset-mcp init --force

For local development, clone the repository and install dependencies with uv:

curl -LsSf https://astral.sh/uv/install.sh | sh    # if uv is not installed
uv sync --extra dev --extra moomoo --extra longbridge
uv run asset-mcp init --path config.local.yaml

If you do not need moomoo or Longbridge support, omit those optional extras:

uv sync --extra dev

Configure

asset-mcp init writes the starter template to ~/.config/asset-mcp/config.local.yaml. Pass --path <file> to write the template anywhere other than the default location.

If you installed from PyPI, asset-mcp init writes the same template the repository ships as config.example.yaml. Refer to that file on GitHub (see Links below) for the complete set of supported fields and inline comments.

Keep real API keys and personal balances only in your local config file — never commit it. Each account id must be unique and stable; this id appears in MCP responses and is used for filtering.

Binance

Create a read-only API key in the Binance API management console. Keep Withdraw, Trade, Margin, and Futures permissions disabled.

exchanges:
  binance:
    accounts:
      - id: binance-main
        label: Binance Main
        enabled: true
        apiKey: "replace-with-read-only-key"
        apiSecret: "replace-with-read-only-secret"
        # environment: production    # optional

OKX

Create an OKX API key with Read permission only. The passphrase is the one you chose when generating the key.

exchanges:
  okx:
    accounts:
      - id: okx-main
        label: OKX Main
        enabled: true
        apiKey: "replace-with-read-only-key"
        apiSecret: "replace-with-read-only-secret"
        passphrase: "replace-with-passphrase"
        # domain: https://www.okx.com   # optional

moomoo (OpenD)

Install and start the Futu/moomoo OpenD client and log in before launching asset-mcp. Install the optional SDK with pip install "asset-mcp[moomoo]".

brokers:
  moomoo:
    accounts:
      - id: moomoo-us
        label: moomoo US
        enabled: true
        host: 127.0.0.1
        port: 11111
        trdMarket: US                # US / HK / CN / SG
        securityFirm: FUTUSECURITIES # or FUTUINC / MOOMOOSG / FUTUSG
        # accountId: 12345678        # optional; only needed for multi-account setups

Longbridge

Create a Longbridge OpenAPI application with read-only scopes and copy the App Key, App Secret, and Access Token. Install the optional SDK with pip install "asset-mcp[longbridge]".

brokers:
  longbridge:
    accounts:
      - id: longbridge-main
        label: Longbridge Main
        enabled: true
        appKey: "replace-with-app-key"
        appSecret: "replace-with-app-secret"
        accessToken: "replace-with-access-token"

IBKR

IBKR support uses Flex Web Service. In IBKR Client Portal, enable Flex Web Service, create an Activity Flex Query that outputs XML, and include at least Cash Report and Open Positions. Then configure the generated token and query ID under brokers.ibkr.accounts:

brokers:
  ibkr:
    accounts:
      - id: ibkr-main
        label: IBKR Main
        enabled: true
        token: "replace-with-flex-web-service-token"
        queryId: "replace-with-flex-query-id"
        baseUrl: https://ndcdyn.interactivebrokers.com/AccountManagement/FlexWebService
        accountId: U1234567
        version: 3
        statementRetries: 3
        statementRetryDelaySeconds: 5

Leave accountId empty to import every account included in the Flex Query, or set it to keep only one account from a multi-account report. Flex Activity Statement data is report data rather than a real-time feed, so use it for periodic net-worth snapshots instead of active polling.

On-chain wallets

Configure public wallet addresses under onchain.accounts. The provider discovers assets held by each address. EVM chains query native balances plus a built-in mainstream ERC-20 token list, and any ERC-20 contracts explicitly configured under the address. Solana uses getTokenAccountsByOwner for SPL token accounts. Bitcoin and TRON use public address APIs. No private keys, seed phrases, trading, transfer, or approval operations are supported.

Supported built-in chains:

• bitcoin / btc
• ethereum / eth / 1
• solana / sol / 501
• bsc / bnb / 56
• tron / trx
• polygon / matic / 137
• avalanche / avax / 43114
• arbitrum / 42161
• base / 8453
• optimism / op / 10

Example on-chain wallet address config:

onchain:
  accounts:
    - id: onchain-wallet
      label: On-chain Wallet
      enabled: true
      addresses:
        - chain: bitcoin
          address: "bc1..."
        - chain: ethereum
          address: "0x..."
          tokens:
            - symbol: CUSTOM
              name: Custom ERC-20 Token
              contractAddress: "0x..."
              decimals: 18
              coinGeckoId: ""
        - chain: solana
          address: "..."
        - chain: bsc
          address: "0x..."

Each address can override rpcUrl or explorerApiUrl if you prefer your own node or paid provider over the default public endpoints. Native token prices are read from rates first, then CoinGecko. Solana SPL tokens without a Jupiter price are still returned with zero USD value.

For configured ERC-20 tokens, symbol, contractAddress, and decimals are required. name is optional. Add coinGeckoId for live USD pricing, or provide the token price under rates; if no price is available the token is still returned with zero USD value. If a Covalent indexer is enabled, configured ERC-20 contracts are queried in addition to the indexed inventory, skipping contracts already returned by the indexer.

For an Etherscan-like full token inventory instead of the built-in mainstream EVM token list, configure an optional indexer:

onchain:
  indexer:
    provider: covalent
    apiKey: "replace-with-covalent-api-key"

Manual assets & rates

USD value for each manual asset is computed as quantity * rates[currency]. On-chain native tokens read rates first and fall back to CoinGecko.

rates:
  USD: 1.0
  CNY: 0.14
  HKD: 0.128

manual:
  accounts:
    - id: alipay
      label: Alipay
      enabled: true
      category: cash
      assets:
        - symbol: CNY
          quantity: 25000
          currency: CNY
    - id: home
      label: Primary residence
      enabled: true
      category: property
      assets:
        - symbol: USD
          quantity: 500000
          currency: USD

Run the MCP Server

asset-mcp

By default the server reads config in this order:

1. ASSET_MCP_CONFIG
2. config.local.yaml in the current directory
3. ~/.config/asset-mcp/config.local.yaml

To use another path:

ASSET_MCP_CONFIG=/path/to/config.local.yaml asset-mcp

MCP Client Configuration

Use stdio transport. Example client configuration:

{
  "mcpServers": {
    "asset-mcp": {
      "command": "asset-mcp"
    }
  }
}

If you prefer a non-default config path, pass an absolute path through ASSET_MCP_CONFIG.

MCP Tools

• get_net_worth: total net worth and grouped summaries.
• get_assets: normalized asset rows with optional filters.
• get_asset_dashboard_data: chart-ready grouping data.
• health_check_sources: per-account configuration and connection status.

Provider calls are isolated with per-provider timeouts. When querying multiple providers, a slow or unavailable source is reported in providerErrors and the tool returns the data that was available with partial: true. SDK-backed providers that can block or emit native stdout run in a subprocess, so timed-out requests can be terminated without leaving the MCP server blocked or corrupting stdio transport.

providerErrors entries include stable machine-readable codes:

Example prompt after connecting the MCP server:

Use asset-mcp to summarize my net worth by account and asset category.

To verify your setup end-to-end, ask the MCP client to call health_check_sources. Every enabled account should return ok: true; anything else points at a misconfiguration or unreachable provider.

Troubleshooting

• `health_check_sources` returns `configured: false` for every account.

Confirm the config file is in one of the three resolved locations (ASSET_MCP_CONFIG, the current directory, or ~/.config/asset-mcp/config.local.yaml) and that each account has enabled: true.

• moomoo accounts report `provider_exited` or `provider_timeout`. OpenD

is not running, not logged in, or the port is blocked. Verify the daemon with nc -z 127.0.0.1 11111 and confirm you installed the SDK extras: pip install "asset-mcp[moomoo]".

• Responses include `partial: true` and a `providerErrors` array. One or

more providers failed. provider_timeout is safe to retry; provider_exception usually means an expired or wrong credential; provider_exited indicates a subprocess-isolated provider crashed (often moomoo/Longbridge SDK issues).

• The MCP client shows "Transport closed" right after connecting. A

provider likely wrote a banner or warning to stdout and corrupted the JSON-RPC stream. Run ASSET_MCP_CONFIG=config.local.yaml asset-mcp in a terminal and look for any unexpected output before the first JSON frame.

• An on-chain address shows zero balance even though it holds tokens.

Verify the chain value matches one of the supported aliases, and that any custom ERC-20 entry has all three of symbol, contractAddress, and decimals.

Security Notes

• Use read-only API keys for exchanges.
• Do not commit config.local.yaml.
• Do not enable withdrawal, transfer, or trading permissions on API keys.
• Use Longbridge API key credentials with read-only permissions where

possible.

• Use IBKR Flex Web Service only for read-only reporting queries.
• Bank and Alipay balances are manual entries only; this project does not

scrape or automate those services.

• On-chain wallet support is address-based and read-only. Do not enter

private keys or seed phrases in the config.

Compatibility re-export modules are kept for older imports such as asset_mcp.models, asset_mcp.aggregation, and asset_mcp.providers.binance. New code should prefer the package paths above.

Development

Install development dependencies before running tests:

uv sync --extra dev

The regression tests use fake provider clients and inline sample config data. They do not require config.local.yaml, real API keys, running OpenD, broker SDK sessions, or outbound network access.

Run tests:

uv run pytest

Run a syntax check with Python's compiler:

uv run python -m compileall src tests

Run the server locally against the example config:

ASSET_MCP_CONFIG=config.example.yaml uv run asset-mcp

Build local package artifacts:

uv build

This writes wheel and source distribution files under dist/.

Release checklist

• Update the package version in both pyproject.toml and the fallback

__version__ value in src/asset_mcp/__init__.py.

• Run uv run python -m compileall src tests and uv run pytest.
• Run uv build and inspect the source distribution for local-only files

before publishing.

• Publish from a GitHub release so the PyPI workflow builds, tests, and uploads

the final artifacts.

Adding Providers

• Add crypto exchanges under src/asset_mcp/providers/exchanges/<platform>/.
• Add brokerage integrations under

src/asset_mcp/providers/brokerages/<platform>/.

• Add manual or on-chain behavior under their existing provider packages.
• Register the new source in src/asset_mcp/providers/registry.py.
• Extend config models/parsing under src/asset_mcp/config/ when the

provider needs new YAML fields.

• Add provider regression tests under tests/providers/.
• Preserve existing MCP response shapes and source names unless you

intentionally change the public contract and update tests and docs together.

Provider stdout hygiene

The MCP server uses stdio transport, so stdout is reserved for JSON-RPC protocol frames. Any banner, warning, permission table, progress line, or native SDK log written to stdout can corrupt the MCP stream and surface in clients as Transport closed.

When adding a new broker or exchange provider:

• Wrap all third-party SDK calls with

asset_mcp.providers.stdio.redirect_sdk_stdout().

• Assume SDKs may bypass print() and write directly to file descriptor 1

from native code or background threads; contextlib.redirect_stdout() alone is not enough.

• Exercise every network/API path, not only health checks. Quote/market-data

endpoints often emit permission tables even when account-balance endpoints are quiet.

• Add a regression test using capfd and os.write(1, ...) to prove

provider calls leave stdout empty.
