How to update vector indices with your AI

Connect LanceDB to your AI client once. After that, your agent handles the data ingestion and index refreshes for you.

Short answer

How can I add new data to my LanceDB vector index using AI?

Your agent uses the LanceDB MCP to push new rows and embeddings directly into your existing tables. This triggers an immediate update to your ANN index. You get a live, updated knowledge base.

The outcomes.

Where your data lands.

What happens once your agent processes the new information.

INDEX

Immediate ANN updates

The agent pushes new embeddings into the table. Your vector search results reflect this new data immediately.

DATA

Structured storage

New rows land in your LanceDB tables alongside their vectors. Your metadata stays synced with the embeddings.

SYNC

Real-time availability

The AI ensures the new information is searchable. You don't have to wait for a batch job to finish.

HUMAN

Manual review needed

The agent inserts the data, but you still need to verify the source information is correct.

The workflow

What your AI does when data arrives.

The agent handles the database writes so you don't have to.

  1. Data preparation

    Your agent takes the raw text or structured info you provide and prepares it for the database.

    insert_rows

  2. Row insertion

    The agent writes the new records and their corresponding embeddings into your LanceDB table.

    insert_rows

  3. Index refresh

    The database automatically updates the ANN index to include the newly inserted vectors.

    insert_rows

  4. Verification

    The agent confirms the write was successful so you can immediately query the new data.

    insert_rows

FAQ

How this task behaves.

  • 01

    Does the AI automatically create new tables?

    No. The agent uses the existing tables you have already set up in LanceDB.

  • 02

    Can the AI delete old vectors to save space?

    No. This MCP only handles inserting new rows; it does not have tools for deleting or dropping data.

  • 03

    How fast is the index update?

    The update happens as part of the insertion process, making the new vectors available for search immediately.

  • 04

    Do I need to provide the embeddings myself?

    Your AI client handles the embedding generation before calling the tool to insert the rows.

  • 05

    Can the AI change the schema of my table?

    No. The agent can only add rows that match your existing table structure.
