# MongoDB

The `robomotion mongodb` CLI connects to MongoDB for document database operations. It supports finding, inserting, updating, and deleting documents; running aggregation pipelines; and managing collections.

## When to use
- Query documents with filters and projections
- Insert, update, or delete documents in collections
- Run aggregation pipelines for data analysis
- Manage MongoDB connections and collections

## Prerequisites
- `robomotion` CLI installed
- Package installed: `robomotion install mongodb`
- MongoDB connection URI configured via Robomotion vault

## IMPORTANT: Session Mode Required for Multi-Step Operations
Each CLI command runs as a **separate process** — connection IDs from `connect` do NOT persist across calls.
You MUST use `--session` on `connect` and pass `--session-id` to all subsequent commands.

## Workflow
1. Install (once): `robomotion install mongodb`
2. Connect with session:
   ```
   robomotion mongodb connect --session --output json
   # → {"outConnectionId":"<conn-id>","session_id":"<session-id>"}
   ```
3. Use the returned `conn-id` and `session-id` in all subsequent commands:
   ```
   robomotion mongodb find --conn-id "<conn-id>" --collection <col> --filter <json> --session-id "<session-id>" --output json
   ```
4. Disconnect when done:
   ```
   robomotion mongodb disconnect --conn-id "<conn-id>" --session-id "<session-id>" --output json
   ```

**Always** append `--output json` to get structured JSON results.
