Overview

Description from the maker (original English)

Stdio MCP adapter bridging AI clients to pREST’s HTTP /_mcp endpoint for PostgreSQL APIs.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Databases & datasets
  • You need to fill in: PREST_MCP_URL, PREST_MCP_TOKEN

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: PREST_MCP_URL, PREST_MCP_TOKEN, PREST_MCP_TIMEOUT_MS

Values marked secret are keys to your account. Never share them or paste them into a chat.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • PREST_MCP_URL required env
    URL of your running pREST HTTP MCP endpoint, for example http://localhost:3000/_mcp
  • PREST_MCP_TOKEN secret env
    Optional bearer token used to authenticate with the pREST MCP endpoint.
  • PREST_MCP_TIMEOUT_MS env
    Optional HTTP timeout in milliseconds. Defaults to 30000.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is pREST safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: PREST_MCP_URL, PREST_MCP_TOKEN

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.3) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Docker on your computer.

What can I use instead?

In the same category: Supabase, MongoDB MCP Server, Elasticsearch MCP Server

pREST MCP Adapter

Official stdio adapter for pREST’s HTTP MCP endpoint.

This adapter lets MCP clients that require stdio connect to a running pREST instance exposing an HTTP MCP endpoint at /_mcp.

MCP client / AI IDE

↓ stdio (NDJSON JSON-RPC) prest-mcp ↓ HTTP POST http://localhost:3000/_mcp ↓ pREST

The adapter is a tiny transport bridge. It does not introspect schemas, generate SQL, or implement MCP tools. Those live in pREST.

Requirements

  • A running pREST instance with the /_mcp route available
  • Go 1.26+ (to build from source)

Environment variables

VariableRequiredDefaultDescription
PREST_MCP_URLyes—URL of the pREST HTTP MCP endpoint, e.g. http://localhost:3000/_mcp
PREST_MCP_TOKENno—Bearer token when pREST auth is enabled
PREST_MCP_TIMEOUT_MSno30000HTTP timeout in milliseconds

Install

From source
go install github.com/prest/prest-mcp-adapter/cmd/prest-mcp@latest
Docker / OCI
docker pull ghcr.io/prest/prest-mcp-adapter:0.1.3

Local usage

PREST_MCP_URL=http://localhost:3000/_mcp prest-mcp
With token
PREST_MCP_URL=https://api.example.com/_mcp \

PREST_MCP_TOKEN=secret \ prest-mcp

Docker usage
docker run --rm -i \

-e PREST_MCP_URL=http://host.docker.internal:3000/_mcp \ ghcr.io/prest/prest-mcp-adapter:0.1.3

MCP client configuration

Cursor

Add to your MCP settings (e.g. .cursor/mcp.json):

{

"mcpServers": { "prest": { "command": "prest-mcp", "env": { "PREST_MCP_URL": "http://localhost:3000/_mcp" } } } }

Claude Desktop

Add to claude_desktop_config.json:

{

"mcpServers": { "prest": { "command": "prest-mcp", "env": { "PREST_MCP_URL": "http://localhost:3000/_mcp" } } } }

Generic MCP client

Any client that can launch a stdio MCP server:

PREST_MCP_URL=http://localhost:3000/_mcp prest-mcp

Protocol messages are newline-delimited JSON-RPC on stdin/stdout. Logs go only to stderr.

Security recommendation

Use a read-only PostgreSQL user for AI/MCP workflows unless write access is explicitly required.

Do not expose unauthenticated MCP endpoints publicly.

Prefer local or private-network pREST MCP endpoints.

When pREST auth is enabled, set PREST_MCP_TOKEN to a valid JWT.
