How to Use the Elasticsearch Vector MCP in Cursor

Q: How do I add the Elasticsearch Vector MCP Server to Cursor?

Create a .cursor/mcp.json file in your project root and define this server under the mcpServers key. Once saved, Cursor's MCP agent mode instantly gains access to the vector search and indexing tools.

Q: Does the Elasticsearch Vector integration support multi-file codebase edits?

Yes, Cursor's agent can use the search tool to fetch vector results and then edit multiple files across your workspace to integrate the new search payload structure.

Q: What happens if my vector dimensions do not match the index mapping?

The indexdocument tool returns an explicit mapping error from your Elasticsearch cluster. Your agent reads this error and helps you adjust your embedding generation code to match.

Generate working code using live vector search results from your Elasticsearch cluster inside Cursor.

Pull live vector context into Cursor Composer

The `search` tool executes real-time kNN queries against your Elasticsearch cluster directly from your active editing session. Instead of mocking search payloads, Cursor uses actual vector scores to build and test your retrieval logic. This live feedback loop means you write integration tests that run against real data. Your agent inspects the returned document schemas to write precise parser functions on the spot.

Map and inspect indexes using Cursor MCP Server

The `get_index` tool retrieves mapping structures from your cluster to help you write exact TypeScript interfaces. Cursor reads the dense vector dimension limits and auto-completes your data models. Creating new test environments takes seconds with the `create_index` tool. You do not need to leave your code editor to run curl scripts or configure database mappings manually.

Manage vector records during active coding

The `index_document` tool pushes new vector payloads into your cluster directly from your terminal or chat window. This lets you populate your local development index with sample embeddings while debugging. Removing bad test data is handled by the `delete_document` tool. Your agent runs this command to prune corrupted embeddings, keeping your search evaluations clean.

Setup guide

Set up Elasticsearch Vector MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the Elasticsearch Vector MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent Elasticsearch Vector transactions." If the MCP tools are loaded correctly, Cursor will call the Elasticsearch Vector tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "elasticsearch-vector-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
  }
}

Common questions about Elasticsearch Vector MCP in Cursor

Create a `.cursor/mcp.json` file in your project root and define this server under the `mcpServers` key. Once saved, Cursor's MCP agent mode instantly gains access to the vector search and indexing tools.

Yes, you can generate embeddings in your code and pass them to the `index_document` tool via Cursor's chat. This lets you verify that your vector dimensions match your Elasticsearch index configuration.

Yes, Cursor's agent can use the `search` tool to fetch vector results and then edit multiple files across your workspace to integrate the new search payload structure.

The `index_document` tool returns an explicit mapping error from your Elasticsearch cluster. Your agent reads this error and helps you adjust your embedding generation code to match.

Your index mappings and vector payloads flow directly through encrypted local transport. This MCP server runs in an isolated runtime, ensuring your raw embeddings and database credentials never touch external telemetry systems.
