Epsilla MCP server

This MCP (Model Context Protocol) server integrates with Epsilla, providing a standardized interface for managing vector storage in AI applications. It enables seamless interaction with Epsilla databases through simple API calls, supporting operations like table management and data manipulation.

Installation

Prerequisites

• Python 3.8 or higher
• Git

Setup

1. Clone the repository:

    "table_name": "my_vectors",
    "dimension": 1536,
    "metric": "cosine"
  }'

List Tables

curl -X GET http://localhost:8000/table/list

Delete a Table

curl -X DELETE http://localhost:8000/table/delete \
  -H "Content-Type: application/json" \

  -d '{
    "table_name": "my_vectors",
    "documents": [
      {
        "id": "doc1",
        "vector": [0.1, 0.2, 0.3, ...],
        "metadata": {"source": "example"}
      }
    ]
  }'

Query Data

curl -X POST http://localhost:8000/data/query \
  -H "Content-Type: application/json" \
  -d '{
    "table_name": "my_vectors",
    "query_vector": [0.1, 0.2, 0.3, ...],
    "top_k": 5
  }'

Get Data by ID

curl -X POST http://localhost:8000/data/get \
  -H "Content-Type: application/json" \
  -d '{

    "ids": ["doc1", "doc2"]
  }'

Delete Data

curl -X POST http://localhost:8000/data/delete \
  -H "Content-Type: application/json" \
  -d '{
    "table_name": "my_vectors",
    "ids": ["doc1"]
  }'

Configuration Options

Server Configuration

You can configure the server by setting environment variables:

• EPSILLA_HOST: Hostname of the Epsilla server (default: localhost)
• EPSILLA_PORT: Port of the Epsilla server (default: 8888)
• MCP_PORT: Port for the MCP server (default: 8000)

Advanced Query Options

When querying data, you can use additional parameters:

curl -X POST http://localhost:8000/data/query \
  -H "Content-Type: application/json" \
  -d '{
    "table_name": "my_vectors",
    "query_vector": [0.1, 0.2, 0.3, ...],
    "top_k": 5,
    "filter": {"source": "example"},
    "include_metadata": true,
    "include_vectors": false
  }'

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "epsilla" '{"command":"npx","args":["-y","mcp-epsilla"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "epsilla": {
            "command": "npx",
            "args": [
                "-y",
                "mcp-epsilla"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "epsilla": {
            "command": "npx",
            "args": [
                "-y",
                "mcp-epsilla"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
