Bring Embeddings
to AutoGen
Create your Vinkius account to connect pgvector (Vector Database) to AutoGen and start using all 6 AI tools in minutes. Fully managed, enterprise secure, and ready to use without writing a single line of code. No hosting, no server setup — just connect and start using.
Compatible with every major AI agent and IDE
What is the pgvector (Vector Database) MCP Server?
Connect your PostgreSQL + pgvector database to any AI agent and manage vector embeddings, similarity searches, and index optimizations through natural conversation.
What you can do
- Vector Similarity Search — Run nearest-neighbor queries using cosine, L2, or inner product distance metrics across millions of embeddings with a single prompt.
- Table Management — Discover which tables contain vector columns, create new embedding tables with custom dimensions, and inspect your schema.
- Embedding CRUD — Insert, update, and delete individual vector entries with metadata, keeping your knowledge base fresh and accurate.
- Index Optimization — Create HNSW or IVFFlat indexes on vector columns to accelerate approximate nearest-neighbor (ANN) queries by orders of magnitude.
How it works
- Subscribe to the pgvector integration on the marketplace.
- Paste your PostgreSQL connection string (e.g.,
postgresql://user:pass@host:5432/db). - Ask your AI agent to search vectors, create tables, or optimize indexes.
Who is this for?
- AI Engineers — Build RAG (Retrieval-Augmented Generation) pipelines that query production embeddings without writing custom API endpoints.
- Data Architects — Manage vector schemas, monitor index performance, and optimize query latency from a single conversational interface.
- Fullstack Developers — Add semantic search to existing apps by querying pgvector directly through your AI agent, no new microservices needed.

Why AutoGen?
AutoGen enables multi-agent conversations where agents negotiate, delegate, and collaboratively use pgvector (Vector Database) tools. Connect 6 tools through Vinkius and assign role-based access. a data analyst queries while a reviewer validates, with optional human-in-the-loop approval for sensitive operations.

Multi-agent conversations: multiple AutoGen agents discuss, delegate, and collaboratively use pgvector (Vector Database) tools to solve complex tasks
- —
Role-based architecture lets you assign pgvector (Vector Database) tool access to specific agents. a data analyst queries while a reviewer validates
- —
Human-in-the-loop support: agents can pause for human approval before executing sensitive pgvector (Vector Database) tool calls
- —
Code execution sandbox: AutoGen agents can write and run code that processes pgvector (Vector Database) tool responses in an isolated environment

Frequently asked questions
Does the agent connect directly to my database?
Yes. Your connection string is encrypted at rest and injected into an isolated runtime. The agent connects directly to your PostgreSQL instance — no intermediate proxies, no data copies, no third-party storage.
What vector dimensions are supported?
Any dimension supported by pgvector — from small 128-d vectors to large 3072-d embeddings (e.g., OpenAI text-embedding-3-large). Specify the dimension when creating a table and the agent handles the rest.
Which distance metrics can I use for similarity search?
pgvector supports three operators: <-> (L2/Euclidean distance), <=> (cosine distance), and <#> (negative inner product). The agent uses cosine distance by default, which works best for normalized embeddings like those from OpenAI.
How does AutoGen connect to MCP servers?
Create an MCP tool adapter and assign it to one or more agents in the group chat. AutoGen agents can then call pgvector (Vector Database) tools during their conversation turns.
Can different agents have different MCP tool access?
Yes. AutoGen's role-based architecture lets you assign specific MCP tools to specific agents, so a querying agent has different capabilities than a reviewing agent.
Does AutoGen support human approval for tool calls?
Yes. Configure human-in-the-loop mode so agents pause and request approval before executing sensitive MCP tool calls.
