iwym-assets-mcp

stdio MCP server that lets a Grok Bot maintain the iwym asset whitelist (assets + asset_venue_codes). It wraps the operator HTTP API. It does not open exchange orders and it does not turn on auto_exec.

The bot is expected to verify one asset at a time (1000SHIB vs SHIB, the same ticker on two venues, Kraken XBT, leveraged tokens) and then write. Catalog diff is the read side of that loop.

Requirements

• Python 3.11+
• uv
• A running iwym API (IWYM_API_BASE_URL)
• An operator API token from Settings → System → OPERATOR API (paste it as IWYM_OPERATOR_TOKEN here)

1. API token

Log into the iwym console and open Settings → System. The OPERATOR API panel shows whether a token is set and when it was last rotated.

• Generate creates a token when none is stored.
• Reset rotates it. The previous Bearer stops working immediately.
• The plaintext is shown once. Copy it into IWYM_OPERATOR_TOKEN. It is not written to .env on the API, and the API stores only a SHA-256 digest.

The token acts as the operator who generated it. It has the same power as that logged-in operator. Cookie login is unchanged. This Bearer works in any APP_ENV and does not need a CSRF cookie.

AUTH_ALLOW_BEARER is only for short-lived JWTs in development. Do not use it for this MCP.

2. Connect (Cursor / Grok Bot)

From a local checkout:

{
  "mcpServers": {
    "iwym-assets": {
      "command": "uv",
      "args": [
        "--directory",
        "/ABS/PATH/iwym-next/mcp/iwym-assets",
        "run",
        "iwym-assets-mcp"
      ],
      "env": {
        "IWYM_API_BASE_URL": "http://127.0.0.1:8000",
        "IWYM_OPERATOR_TOKEN": "paste-from-settings-system-operator-api"
      }
    }
  }
}

IWYM_API_BASE_URL is the API origin only (no /api/v1 suffix).

cd mcp/iwym-assets
uv sync
export IWYM_API_BASE_URL=http://127.0.0.1:8000
export IWYM_OPERATOR_TOKEN=paste-from-settings-system-operator-api
uv run iwym-assets-mcp

stdio waits for the host. Missing env vars exit 1 with a stderr hint.

3. Tools

Re-enable a staged row with PATCH /api/v1/assets/{id} {"enabled": true} (no MCP tool; use the HTTP API or extend the server). auto_exec is not touched.

catalog_diff

Spot and perp legs only. Unique base codes, not BTCUSDT rows. Tradable instruments only.

Each entry:

• status: missing (no (venue, code) row), disabled (mapped, asset enabled=false), orphan (whitelist code absent from the catalog; only when include_orphans=true and that venue's spot and perp reads both succeeded)
• suggested_asset_id: lowercase slug, or null when the code cannot be an id (1000SHIB)
• already_mapped_asset_id / mapped_asset_enabled
• market_types: spot and/or perp
• alias_note: catalog folds (XBT→BTC, XDG→DOGE), multiplier prefixes, leveraged-token suffixes

errors[] means that market was not read. Do not treat orphans as complete for a venue listed there.

create_or_upsert_asset

One asset per call. Pass venue + code, or venue_codes_json as [{"venue":"binance","code":"SHIB"}].

• Asset missing: create it (tool default enabled=false) and attach codes that are free. Response HTTP 201, created: true.
• Asset exists and kind/oracle/anchor match: attach free codes. Codes already on this asset are unchanged. HTTP 200. Scalar fields are not updated (enabled stays as stored).
• Code belongs to another asset, or kind/oracle/anchor differ: HTTP 409, nothing written. error.details.conflicts lists {venue, code, asset_id}.

4. Suggested bot loop

1. catalog_diff(venue="binance").
2. Read one missing entry. If alias_note mentions a multiplier, leverage suffix, or folded alias, stop and ask.
3. get_asset(suggested_asset_id) when the suggestion is non-null.
4. create_or_upsert_asset with enabled=false and that one venue code.
5. On 409, stop. Do not pick a new id to steal the code.
6. Leave the row disabled until a human wants it in the Radar scan set.

5. Security

• Never commit IWYM_OPERATOR_TOKEN. The API does not read OPERATOR_API_TOKEN from the environment.
• The token is not a trading key. It can still change the whitelist.
• Settings UI CRUD (POST /assets, PATCH, venue codes, contract paste) is unchanged.
