Nothing serious here today

Today is the operative word: we check pgvector every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

Claude Code Claude Desktop Codex Cursor VS Code

run in your terminal

claude mcp add pgvector -- uvx mcp-server-pgvector

~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "pgvector": {
      "args": [
        "mcp-server-pgvector"
      ],
      "command": "uvx"
    }

command = "uvx"
args = ["mcp-server-pgvector"]

{
  "mcpServers": {
    "pgvector": {

        "mcp-server-pgvector"

This one needs environment variables set before it will start: DATABASE_URL (PostgreSQL connection string, e.g. postgresql://user:password@host:5432/dbname), MCP_PGVECTOR_READ_ONLY (Set to 'true' to disable upsert_embedding and create_vector_index). The author declared them in the registry entry; get the values from the project itself.

pgvector — questions

Answers built from our own checks of this server.

Why is there no uptime for pgvector?

pgvector runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package mcp-server-pgvector was installed 62 times last week.

How do I connect pgvector?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls mcp-server-pgvector straight from pypi; nothing to host, nothing to sign up for.

How many people use pgvector?

The pypi package mcp-server-pgvector was installed 62 times in the last week. Week over week that is -11%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is pgvector open source?

Yes — it is published under the MIT licence, written in Python and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
