VolcEngine TOS

Sample TOS Model Context Protocol Server

An MCP server implementation for retrieving data from TOS.

Features

Resources

Expose volcengine TOS Data through Resources. (think of these sort of like GET endpoints; they are used to load information into the LLM's context). Currently only PDF documents supported and limited to 1000 objects.

Tools

• ListBuckets
  • Returns a list of all buckets owned by the authenticated sender of the request
• ListObjectsV2
  • Returns some or all (up to 1,000) of the objects in a bucket with each request
• GetObject
  • Retrieves an object from volcengine TOS. In the GetObject request, specify the full key name for the object. General purpose buckets - Both the virtual-hosted-style requests and the path-style requests are supported

Configuration

Setting up volcengine Credentials

1. Obtain volcengine access key ID, secret access key, and region from the volcengine Management Console and configure credentials files using Default profile
2. Ensure these credentials have appropriate permission READ/WRITE permissions for TOS.
