Overview

AI-generated overview

Inspect and manage Estuary Flow data pipelines, including captures, materializations, collections, connectors, drafts, and task logs.

What it does
A hosted MCP server that connects an assistant to Estuary Flow. Read tools list catalog entities, catalog specs and stats, connectors and connector versions, drafts and draft specs, publications, discovers, roles, and tenant details, and view task logs. Write tools create drafts, upsert draft specs, and publish drafts, so pipeline changes can be prepared and released from the assistant.
When to use it
Useful when you work with Estuary Flow data pipelines and want an assistant to inspect catalog state, check connector versions, review publications, or read task logs without opening the Estuary Flow UI. Also relevant when you want to prepare and publish draft changes conversationally.
Requirements
A remote MCP endpoint at no local install or package. Estuary Flow credentials are pasted on first connect and stored per user. Network access to the hosted endpoint is required. A free plan allows 100 tool calls per month; Pro is $9/mo or $90/yr for unlimited calls.
Before you install
The server asks for Estuary Flow credentials, which are validated and stored per user by the provider. Three tools write: create draft, upsert draft spec, and publish draft; publishing can change live pipelines, so confirm before running them. Usage is metered, and exceeding the free 100 calls per month requires a paid plan.
