VolcEngine TOS MCP Server

The VolcEngine TOS MCP Server turns a cloud object‑storage service into an AI‑friendly data lake. By exposing TOS buckets, objects and file contents as first‑class tools, the server lets Claude or other assistants answer natural‑language questions about data that lives in a private cloud. Instead of manually querying the TOS console or writing SDK calls, developers can ask the assistant to list buckets, enumerate files, or fetch a text document and receive an instant answer. This dramatically reduces the friction of data exploration in enterprise environments where security, compliance and large‑scale storage are already managed by VolcEngine.

At its core the server offers three intuitive tools: list_buckets, list_objects and get_object. list_buckets returns a catalog of all accessible storage containers, complete with creation time and endpoint details. list_objects lets the assistant drill into a specific bucket, optionally filtering by prefix or pagination token to handle large inventories. get_object retrieves the raw content of any file; text files are returned as plain strings, while binary assets like images or videos come back as Base64‑encoded blobs. These capabilities enable a wide range of use cases—from generating data summaries, to powering content‑search bots, or feeding structured datasets into downstream AI pipelines—all without exposing credentials or writing custom code.

Because the server is built on the MCP framework, it integrates seamlessly with any AI workflow that supports MCP. A developer can simply add the TOS server to their mcp settings, then invoke the tools in a prompt such as “Show me all objects in the bucket that start with .” The assistant can even combine multiple tool calls: first list objects, then fetch the most recent CSV and parse its rows for analysis. The server’s lightweight design means it can run on local machines, in the cloud, or inside the Arks platform, making it a flexible choice for on‑premises teams that need to keep data in their own VPC.

What sets the TOS MCP Server apart is its tight coupling with VolcEngine’s security model. Authentication uses standard access keys, secret keys and optional session tokens, all configurable through environment variables—no hard‑coded secrets. The server also respects bucket‑level access controls, ensuring that only authorized data is exposed to the assistant. For teams already invested in VolcEngine’s ecosystem, this server offers a plug‑and‑play bridge to AI without rewriting storage logic or compromising governance.
