Direct Vector Search in Claude Desktop

You don't need to write a Python script just to test your embedding clusters. Connect this MCP Server to your local or web setup, and your agent can run `query_embeddings` right in the chat. It finds the exact logical bounds matching your high-dimensional semantic data. That means you can ask about specific concepts, and Claude pulls the nearest neighbors instantly. Need to verify what actually got stored? Have it run `get_documents` to pull the exact physical text and semantic context out of those known arrays.

Audit Your Document Collections

Keeping track of what went into a specific tenant database usually requires bouncing between terminal tabs. Now you can just ask. Use `list_collections` to see every explicitly defined vector block you have running. From there, you can dig into the structural tracking. Run `count_documents` to get the exact volume of records. If you just want a quick look at the data shape, `peek_documents` grabs a bounded preview of the database limits without pulling down the whole index.

Monitor Node Health on the Fly

Sometimes you just need to know if the database is actually up before you start debugging a failed pipeline. The `check_heartbeat` tool validates fundamental network availability against your explicit Chroma API nodes. If the node is alive, you can move on to checking the configuration. Running `get_collection` identifies the bounded logical settings for a specific vector block. You figure out exactly how the distance metrics and dimensions are set up without leaving the conversation.

Setup guide

Set up Chroma (Vector DB) MCP in Claude Web or Desktop

1

Open Claude Settings

Go to claude.ai, click your profile icon, then navigate to Customize → Connectors.
2

Add Custom Connector

Click the "+" button and select Add custom connector. Paste your Vinkius endpoint URL: https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. For OAuth-protected servers, expand Advanced settings to add credentials.
3

Start a conversation

Open a new chat. The Chroma (Vector DB) MCP tools are available immediately — no restart needed.

Endpoint URL

https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp

No configuration file needed — paste the URL directly in the Claude web interface.

Available on Free (1 connector), Pro, Max, Team, and Enterprise plans.

Prerequisites

Claude Desktop installed (macOS or Windows)
Active Vinkius subscription with a valid endpoint token

1

Open Claude Desktop Settings

Click the menu icon at the top-left corner, go to Settings → Developer → Edit Config. This opens claude_desktop_config.json in your default text editor.
2

Paste the Chroma (Vector DB) MCP configuration

Copy the JSON snippet on the right into the mcpServers object. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Restart Claude Desktop

Close and reopen the application. Claude needs a full restart to load new MCPs — refreshing a conversation is not enough.
4

Verify the connection

Open a new conversation. Click the 🔌 icon at the bottom of the message input. You should see tools listed under chroma-vector-db-mcp.

Common questions about Chroma (Vector DB) MCP in Claude Desktop

You have two paths. Add the Vinkius MCP URL to your browser integrations under Settings, or edit the claude_desktop_config.json file for local setups. Both methods give you instant access to your vector collections.

Yes. The server includes tools for retrieving specific records. Your agent pulls exact text and semantic context so you can read the actual content behind the embeddings.

It works perfectly in the browser. You just paste the remote server URL into the Custom Connectors section in your settings. You don't need to install anything locally to start querying your vector database.

Just ask your agent to count them. It runs a structural tracking command that enumerates the total document volumes across your specified collections.

Vinkius runs this connection inside an ephemeral V8 Isolate Sandbox. Your high-dimensional semantic clustering data and physical document text only pass through a zero-trust environment. The system drops the environment the moment your session ends.
