Model Context Protocol Server for Apache OpenDAL™

A Model Context Protocol (MCP) server implementation that provides access to various storage services via Apache OpenDAL™.

Features

Seamless access to multiple storage services including S3, Azure Blob Storage, Google Cloud Storage, and more
List files and directories from storage services

Environment variable based configuration

Environment variables

Configure storage services by setting environment variables. Each service requires a prefix and specific configuration options.

For example, to configure an S3 service with alias "mys3":

Copy & paste — that's it

OPENDAL_MYS3_TYPE=s3
OPENDAL_MYS3_BUCKET=mybucket
OPENDAL_MYS3_REGION=us-east-1
OPENDAL_MYS3_ENDPOINT=http://localhost:9000
OPENDAL_MYS3_ACCESS_KEY_ID=myaccesskey
OPENDAL_MYS3_SECRET_ACCESS_KEY=mysecretkey

Then you can use tool like read and list with mys3://path/to/file.

mcp-server-opendal will also load from .env.

Development

Copy & paste — that's it

npx @modelcontextprotocol/inspector \
 uv run mcp-server-opendal

Copy & paste — that's it

pip install mcp-server-opendal

Before it works, you'll need: YOUR_ENV_VAR

Installation

Copy & paste — that's it

pip install mcp-server-opendal
