Overview

MCP server providing access to various storage services (S3, Azure, GCS, etc.) via Apache OpenDAL, configured through environment variables.

This server is relatively safe for read-only operations on well-configured storage services. The risk increases significantly if write/delete operations are enabled and environment variables are not carefully managed. Ensure proper access control on the underlying storage services.

Performance is largely determined by the latency and throughput of the configured storage services and the efficiency of the OpenDAL library.

Cost depends on the storage costs of the configured services (S3, Azure, GCS, etc.) and any associated data transfer fees.

Security

Auth Method

Environment Variable

Known Risks

!Accidental exposure of sensitive data through misconfigured storage buckets.
!Data corruption or loss due to unintended write or delete operations.
!Unauthorized access if environment variables are compromised.
!Potential for denial-of-service attacks by exhausting storage resources.

Safety Score

moderate risk

Positive

+Read and write operations are confined to configured storage services.
+No direct execution of arbitrary code.
+Configuration via environment variables promotes separation of concerns.
+Utilizes Apache OpenDAL, a well-regarded data access layer.

Risks

-Write and delete operations are possible, posing a risk of data modification or loss.
-Misconfigured environment variables could lead to unintended access or exposure.
-Lack of built-in authentication beyond environment variable-based configuration.
-No explicit sandboxing or resource limits are mentioned.

Use Cases

Data Storage and Retrieval

-Accessing data stored in S3 buckets.
-Reading logs from Azure Blob Storage.
-Retrieving configuration files from Google Cloud Storage.

Content Management

-Listing available assets in a media library.
-Reading content files for processing.
-Storing generated content in a cloud storage service.

Backup and Archiving

-Listing available backups in a storage service.
-Reading archived data for analysis.
-Writing new backups to a designated storage location.

Who Is This For?

Best For

Accessing data across multiple cloud storage providers.
Integrating with applications that require a unified storage interface.
Automating data retrieval and storage tasks.
Environments where storage credentials can be securely managed via environment variables.

Not Ideal For

Scenarios requiring fine-grained access control beyond environment variables.
Environments with strict security requirements that mandate strong authentication and authorization.
Real-time applications with extremely low latency requirements.

Autonomy & Execution

Default ModeConfigurable

Destructive Tools

Autonomy depends entirely on the configured environment variables and the permissions granted to the underlying storage services. Exercise caution when granting write access.

StatelessYes

Retry LogicNot documented

ConcurrencyNot documented

Production Tip

Implement robust monitoring and alerting on the underlying storage services to detect and respond to potential issues.

FAQ

What storage services are supported?

Any storage service supported by Apache OpenDAL, including S3, Azure Blob Storage, Google Cloud Storage, and more.

How do I configure access to my storage service?

By setting environment variables with the appropriate prefix and configuration options for the desired service.

Is authentication required?

Authentication is handled through the configured storage service, typically via access keys or service accounts provided through environment variables.

Can I use this server to delete files?

Yes, if the configured storage service and environment variables allow write and delete operations.

How do I secure my storage credentials?

Store your credentials securely and avoid committing them to version control. Use environment variables and restrict access to the environment where the server is running.

What happens if I misconfigure the environment variables?

The server may fail to connect to the storage service, or it may connect with unintended permissions, potentially leading to data exposure or loss.

Does this server support encryption?

Encryption depends on the configuration of the underlying storage service. Ensure that encryption is enabled at the storage level if required.
