Create a MongoDB CDC capture using flowctl. Use when setting up real-time streaming from MongoDB Atlas, DocumentDB, or self-hosted MongoDB. Use when user says "capture MongoDB", "stream from Mongo", "MongoDB CDC", or "connect MongoDB to Estuary".

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Create MongoDB Capture

Create a MongoDB capture using flowctl to stream data from MongoDB collections into Estuary collections using Change Data Capture (CDC).

**Applies to**: source-mongodb, source-amazon-documentdb, source-azure-cosmos-db

## Step 0: Load Connector Documentation

Before proceeding, fetch the official connector docs for prerequisites, config reference, and deployment-specific setup.

**Always load the main page:**
https://docs.estuary.dev/reference/Connectors/capture-connectors/MongoDB/

**Then load the variant subpage based on the user's deployment:**

| Deployment | Docs URL |
|------------|----------|
| MongoDB Atlas | Main page covers this |
| Self-hosted MongoDB | Main page covers this |
| Amazon DocumentDB | https://docs.estuary.dev/reference/Connectors/capture-connectors/MongoDB/amazon-documentdb/ |
| Azure Cosmos DB | https://docs.estuary.dev/reference/Connectors/capture-connectors/MongoDB/azure-cosmosdb/ |

Use WebFetch to load these pages. Together they cover:

- Prerequisites (replica set requirement, user permissions)
- Full config property reference
- Capture modes (Change Stream Incremental, Batch Snapshot, Batch Incremental)
…

How to install

The exact contents, by fingerprint
mdr add estuary/agent-skills/capture-mongodb-create@sha256:eb2fd3358b42555d

The line at the top of this page pins the label git:20260924.c6e4810, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
