About Supabase Vector MCP Server

Integrate the powerful AI-native PostgreSQL extensions of Supabase Vector straight into your conversational LLM workflows. By authenticating your environment natively with the service_role key, your AI assistant bypasses row-level security constraints to operate as an unrestricted database administrator. Perform advanced similarity searches using the pgvector extension, parse and manipulate multi-dimensional embeddings, and execute foundational CRUD operations via simple natural language commands. Streamline RAG (Retrieval-Augmented Generation) setups and semantic engineering directly, avoiding the need for external dashboards or manual SQL querying.

Pydantic AI validates every Supabase Vector tool response against typed schemas, catching data inconsistencies at build time. Connect 7 tools through Vinkius and switch between OpenAI, Anthropic, or Gemini without changing your integration code. full type safety, structured output guarantees, and dependency injection for testable agents.

What you can do

  • Semantic Vector Matching — Seamlessly query unstructured contextual similarities performing embedding comparisons by executing match_vectors utilizing custom postgres RPC parameters locally.
  • Database Structural Interaction — Systematically browse schema availability utilizing list_tables and extract specific data arrays effortlessly through query_table_rows.
  • Content State Manipulations — Seamlessly orchestrate data inputs invoking insert_table_rows or explicitly clear legacy assignments logically mapping identifiers with delete_table_rows.
  • Custom Functional Logic — Launch sophisticated PL/pgSQL algorithms statically configured in your Supabase backend directly with call_postgres_function.

The Supabase Vector MCP Server exposes 7 tools through the Vinkius. Connect it to Pydantic AI in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

03

Structured output guarantee: Pydantic AI ensures tool results conform to defined schemas, eliminating runtime type errors

04

Dependency injection system cleanly separates your Supabase Vector connection logic from agent behavior for testable, maintainable code

Supabase Vector + Pydantic AI Use Cases

Practical scenarios where Pydantic AI combined with the Supabase Vector MCP Server delivers measurable value.

01

Type-safe data pipelines: query Supabase Vector with guaranteed response schemas, feeding validated data into downstream processing

02

API orchestration: chain multiple Supabase Vector tool calls with Pydantic validation at each step to ensure data integrity end-to-end

03

Production monitoring: build validated alert agents that query Supabase Vector and output structured, schema-compliant notifications

Supabase Vector MCP Tools for Pydantic AI (7)

These 7 tools become available when you connect Supabase Vector to Pydantic AI via MCP:

01

call_postgres_function

Calls a custom Postgres function (RPC) with parameters

02

delete_table_rows

This action is irreversible. Deletes rows from a table based on a column value

03

get_table_row

Retrieves a specific row by matching a column value

04

insert_table_rows

Provide a JSON array of row objects. Inserts new rows into a specific table

05

list_tables

Lists all tables in the Supabase project

06

match_vectors

Requires a valid RPC function name and an embedding array. Performs a vector similarity search via Postgres RPC

07

query_table_rows

Provide table name and optional select/limit. Queries rows from a specific table

Example Prompts for Supabase Vector in Pydantic AI

Ready-to-use prompts you can give your Pydantic AI agent to start working with Supabase Vector immediately.

01

"Using the 'match_docs' vector RPC natively, analyze my embedding representation returning seamlessly the top 5 matches."

02

"Browse my schema directly to identify active vector tables and delete any legacy testing embeddings from 'test_docs' securely."

03

"Insert a new embedding natively calling `insert_table_rows` with the corresponding context efficiently."

Supabase Vector + Pydantic AI FAQ

Common questions about integrating Supabase Vector MCP Server with Pydantic AI.

01

How does Pydantic AI discover MCP tools?

Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
02

Does Pydantic AI validate MCP tool responses?

Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
03

Can I switch LLM providers without changing MCP code?

Absolutely. Pydantic AI abstracts the model layer. your Supabase Vector MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
