Self-hosted Nextcloud MCP alternatives
Nextcloud is already self-hosted, and its community server runs locally over stdio against your own instance, reaching files, notes, calendar, and more without anything leaving your network. If you want to keep the server process and credentials local while narrowing to one job, the picks below all install and run locally too.
A few of these reach products whose data lives in a vendor's cloud even when the server runs on your machine. The notes flag that, since self-hosting the server and self-hosting the data are not always the same thing.
The 8 best self-hosted alternatives
Run locally against your own S3-compatible store, the MinIO server browses buckets, reads and writes objects, manages versioning, and asks AI questions about objects, with the data on infrastructure you operate.
Set up MinIO →- Google Drive (Workspace MCP)Community
The Google Workspace server, scoped to Drive, runs locally and searches, reads, creates, and shares Drive files over OAuth. The process stays on your machine, though the files themselves live in Google Drive.
Set up Google Drive (Workspace MCP) → AWS Labs' server runs locally and executes any AWS CLI command, reaching S3 storage and the wider platform, all driven from a process on your own machine even though the resources sit in AWS.
Set up AWS (AWS Labs) →The community Slack server runs locally over stdio and reads history, DMs, and search with no workspace bot, the local option for the team chat that Nextcloud Talk covers.
Set up Slack →If you used Nextcloud Tables, the maintained Airtable server runs locally and is schema-first: inspect a base, then read, search, and write records, fields, and comments, all from a process you control.
Set up Airtable →For the notes-and-docs side, the Coda server runs on your own machine and connects an agent to docs, pages, tables, and rows for reading and editing, a document model you drive locally.
Set up Coda →- AzureOfficial
Microsoft's Azure server runs locally and manages 40+ services including Blob storage, Key Vault, and Cosmos DB, a full cloud you drive from your own machine when files are part of a larger Azure footprint.
Set up Azure → - DigitalOceanOfficial
DigitalOcean's official server runs locally and manages App Platform, Droplets, managed databases, Spaces object storage, and more, a mid-weight cloud kept on your own infrastructure.

How to choose
For data that truly stays on your own systems, MinIO is the closest match, an object store you self-host like Nextcloud. The Google Drive, AWS, Azure, and DigitalOcean servers run locally but reach data in a vendor's cloud, so the process is yours while the storage is theirs. Airtable and Coda cover the tables and notes corners of Nextcloud, and Slack covers chat. Running the server locally controls where the process lives, not always where the data does.
FAQ
- Can the Nextcloud MCP server be self-hosted?
- Yes. Nextcloud is self-hosted by design, and its community server runs locally over stdio against your own instance, so the process, credentials, and data stay on your infrastructure. Every alternative here also runs locally.
- Do these alternatives keep file data on my own systems?
- Only some. MinIO stores objects on infrastructure you operate. The Google Drive, AWS, Azure, and DigitalOcean servers run locally but call clouds where the data actually lives, so the server is local while the storage is not. Match that to how strict your data-residency need is.
