- LLM-Powered: Natural language processing with Anthropic Claude
- Beautiful Output: Formatted tables, charts, and data visualization
- Tool Management: Automatic tool discovery and validation
- Smart Parsing: Vietnamese stock symbol and date format support
- Error Handling: Robust error recovery and user-friendly messages

Quick Start

# Install from PyPI and run directly
uvx vnstock-mcp@latest

Usage Examples

> Show me FPT's income statements for 2024
> What are HPG's key financial ratios?

Data Sources

This server uses vnstock 4.x public adapters:

- Financial statements and ratios use Finance(source="KBS") for consistent item, item_id, and period-column output. Financial labels are provider-native; use item_id for stable metric identification.
- Company information uses Company(source="VCI") because ratio_summary and trading_stats are VCI-specific compatibility methods.
- Mutual fund data uses the top-level Fund adapter.

Financial statement and ratio responses are returned as metric rows with period columns:

item | item_id | 2025 | 2024 | 2023 | 2022

The reports company info type is not supported in vnstock 4.x and has been removed.

Claude Desktop Integration

To use this MCP server with Claude Desktop, add the following configuration to your Claude Desktop config file (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

Method 1: Using uvx (if PATH configured)

{
  "mcpServers": {
    "vnstock-mcp": {
      "command": "uvx",
      "args": ["vnstock-mcp"]
    }
  }
}

Method 2: Using uvx (if PATH NOT configured)

{
  "mcpServers": {
    "vnstock-mcp": {
      "command": "/Users/YOUR_USERNAME/.local/bin/uvx",
      "args": ["vnstock-mcp"]
    }
  }
}

Method 3: Development from source (script path)

{
  "mcpServers": {
    "vnstock-mcp": {
      "command": "uv",
      "args": [
        "--directory",
        "/Users/USERNAME/PATH_TO/src/vnstock_mcp",
        "run",
        "server.py"
      ]
    }
  }
}

Method 4: Development from source (Python module)

{
  "mcpServers": {
    "vnstock-mcp": {
      "command": "uv",
      "args": [
        "--directory",
        "/Users/USERNAME/PATH_TO/vnstock-mcp",
        "run",
        "python",
        "-m",
        "vnstock_mcp.server"
      ]
    }
  }
}

Method 5: Docker MCP Gateway (simple)

{
  "mcpServers": {
    "MCP_DOCKER": {
      "type": "stdio",
      "command": "docker",
      "args": ["mcp", "gateway", "run"]
    }
  }
}

Method 6: Docker MCP Gateway (explicit catalog/registry)

{
  "mcpServers": {
    "mcp-toolkit-gateway": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "-v",
        "/var/run/docker.sock:/var/run/docker.sock",
        "-v",
        "/Users/YOUR_USERNAME/.docker/mcp:/mcp",
        "docker/mcp-gateway",
        "--catalog=/mcp/catalogs/vnstock.yaml",
        "--config=/mcp/config.yaml",
        "--registry=/mcp/registry.yaml",
        "--transport=stdio"
      ]
    }
  }
}

Note:

- Replace YOUR_USERNAME with your actual username in Methods 2 and 6
- Replace USERNAME and PATH_TO with your actual username and path in Methods 3 and 4
- Methods 5 and 6 require Docker Desktop with the MCP Toolkit enabled. See Setup Guide for details
- Method 5 lets Docker manage catalogs automatically; Method 6 pins specific catalog, config, and registry files
- After quitting and restarting Claude Desktop, if it still can't detect the mcp server, check if uvx is in your PATH. If not, add ~/.local/bin to your PATH:

# For zsh (macOS default)
echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.zshrc
source ~/.zshrc
For bash
echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc

Claude Code Integration

claude mcp add vnstock-mcp --transport http https://your-app.onrender.com/mcp

Remote MCP Server

Connect to a hosted VNStock MCP server deployed on Render (or any cloud provider) without installing anything locally. The remote server exposes a Streamable HTTP endpoint at /mcp.

Use the server URL https://your-app.onrender.com/mcp when adding the remote MCP server in each client's GUI. Guides per client:

- Claude Desktop — Add via Settings > MCP Servers
- Claude Code (CLI) — claude mcp add vnstock-mcp https://your-app.onrender.com/mcp --transport http
- Perplexity — Follow Adding Custom Remote Connectors

Note: Replace your-app.onrender.com with your actual Render deployment URL and add /mcp at the end.

You can verify the server is running with a custom health endpoint /health like this :

curl https://your-app.onrender.com/health

When the service is running from a tagged git checkout, the version field in /health reports that tag. For packaged or deployed environments without .git, it falls back to the installed package metadata or VNSTOCK_MCP_VERSION.

Development

Setup the docker mcp gateway Setup Guide
