Datawatch

datawatch

datawatch talks to a data-observability platform's API: platform health and a daily briefing, alerts (summaries, inbox, trends, history and rules), the data assets under observation and their discovery, freshness summaries, checks and schedules, and schema summaries, change lists, baselines and monitoring. One binary serves a command-line interface and a stdio MCP server.

An API key is required. Set ARMOR_API_KEY before use; when it is missing or blank, every tool fails with an error naming the variable before any request is made. The API base URL can be overridden with DATAWATCH_API_URL; when it is not set, calls go to https://api.anomalyarmor.ai (a labelled reconstruction).

Scope note: the platform's documentation enumerates 52 tool names (its own heading says 29 and its version line says 52; the enumerated sections list 52). datawatch implements a labelled core subset of 24 of them — alerts, assets, freshness and schema drift — and omits the metrics, validity, referential, destination, coverage, recommendation, Q&A, intelligence, lineage, job, tag and API-key tools.

Install

npx @reneturcios/datawatch get_alerts_summary

Or run the container image:

docker run -i ghcr.io/cloudcorprecords/datawatch

The container defaults to the MCP server (see below). Pass CLI arguments to use it as a CLI instead.

CLI

The subcommands mirror the MCP tool names:

export ARMOR_API_KEY=...

datawatch health_summary datawatch get_todays_briefing datawatch list_alerts --status open --severity high datawatch list_inbox_alerts --limit 20 datawatch update_alert --alert-id al1 --action acknowledge --comment "looking into it" datawatch get_alert_trends --period 7d datawatch list_alert_rules --asset-id a1 --is-active true datawatch create_alert_rule --asset-id a1 --rule-type freshness --config '{"threshold_hours":24}' datawatch list_assets --source snowflake --search orders datawatch create_asset --name warehouse --source-type snowflake datawatch trigger_asset_discovery --asset-id a1 datawatch check_freshness --asset-id a1 --table-path db.schema.orders datawatch setup_freshness --asset-id a1 --table-path db.schema.orders --check-interval 1h datawatch list_schema_changes --severity breaking datawatch create_schema_baseline --asset-id a1 --description initial datawatch get_schema_monitoring --asset-id a1

datawatch --version

Results print the upstream JSON payload. Exit codes: 0 on success, 1 when a call fails (including a missing key or an upstream API error), 2 for usage errors.

MCP server

One bin serves both faces. The mcp subcommand starts a stdio MCP server:

npx -y @reneturcios/datawatch mcp

MCP client configuration:

{

"mcpServers": { "datawatch": { "command": "npx", "args": ["-y", "@reneturcios/datawatch", "mcp"], "env": { "ARMOR_API_KEY": "..." } } } }

Tools

Development

npm install

npm run build # tsc -> dist/ npm test # node test runner over test/*.test.ts, no network (fake fetch fixtures) npm run dev # run the CLI from source via tsx
