  2. 02Analyze files without uploading their full contents

MCP support

It exposes local CSV and Parquet analysis to MCP clients, including Claude.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

mcp.json · Universal config
{
  "mcpServers": {
    "analyst": {
      "command": "uvx",
      "args": [
        "mcp-analyst"
      ]
    }
  }
}
Run commanduvx mcp-analyst

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

On MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json On Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "analyst": {
      "command": "uvx",
      "args": [
        "mcp-analyst",
        "--file_location",
        "<replace_this_with_path_to_csv_or_parquet_files_on_your_machine>"
      ]
    }
  }
}

How do I provide more than one CSV file?

The server supports the using globs in the file location. So for example if your directory data has more than one csv file then you can give file-location as <parent_path_to_data>/data/*.csv

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
