### Description (declared)

# YugabyteDB MCP Server

An [MCP](https://modelcontextprotocol.io/) server for YugabyteDB and PostgreSQL — lets LLMs (Claude Desktop, Cursor, Windsurf, etc.) summarize schemas, run read-only queries, and execute write statements behind a configurable guardrail layer.

## Features

- **`summarize_database`** — list tables with columns and row counts for a schema (read-only)
- **`run_read_only_query`** — execute a SELECT under `BEGIN READ ONLY`; results returned as JSON (read-only)
- **`run_write_query`** — INSERT/UPDATE/DELETE/MERGE/TRUNCATE/DDL gated by a guardrail blocklist (destructive)

Defense in depth: the write tool is annotated `destructiveHint: true`, so Claude Desktop surfaces a confirmation prompt before every call even when the guardrails would let the statement through.

Optional OAuth (AWS Cognito) and Origin-header validation for self-hosted remote deployments.

## Prerequisites

- Python 3.10+
- [uv](https://docs.astral.sh/uv/) (recommended) or pip
- A reachable YugabyteDB or PostgreSQL database
- An MCP client (Claude Desktop, Cursor, Windsurf, etc.)

## Installation

Three install options, in roughly the order of how end users will reach for them:

```bash
# uvx — no install at all; fetches and runs on demand. Handy for one-off use
# and also the form the MCPB Desktop extension uses internally.
uvx yugabytedb-mcp-server --help

# pipx — installs to an isolated venv, puts the script on $PATH.
pipx install yugabytedb-mcp-server

# uv tool — same idea, uv-managed.
uv tool install yugabytedb-mcp-server

# pip — system-level or current-venv install.
pip install yugabytedb-mcp-server
```

After any of the persistent installs (pipx / uv tool / pip), verify with:

```bash
yugabytedb-mcp --help
# or, equivalently:
yugabytedb-mcp-server --help
```

Both console scripts are registered and point at the same entry point —
`yugabytedb-mcp` is the short form, `yugabytedb-mcp-server` matches the
package name and is what `uvx` resolves to by default.
