### Description (declared)

# AGE MCP Server

[![License](https://img.shields.io/badge/license-MIT-blue.svg)](LICENSE)
![Python](https://img.shields.io/badge/Python-3.13%2B-blue)

An MCP server for querying [Apache AGE](https://age.apache.org/) graphs in PostgreSQL.

Version 0.3.0 makes read-only operation the secure default, adds asynchronous
connection pooling, safe Cypher parameters and bounded cursor pagination, and
returns MCP structured content from every tool.

## Requirements

- Python 3.13 or later
- PostgreSQL with the Apache AGE extension installed and loaded
- A database role restricted to the graphs and operations the MCP client needs

Enable AGE in the target database:

```sql
CREATE EXTENSION IF NOT EXISTS age CASCADE;
```

## Install

With `uv`:

```bash
uv init your_project
cd your_project
uv add age_mcp_server
```

With a Python virtual environment:

```bash
python3 -m venv .venv
source .venv/bin/activate
python3 -m pip install age_mcp_server
```

With Homebrew:

```bash
brew install rioriost/tap/age_mcp_server
```

## Configure an MCP client

Avoid placing a database password in command-line arguments. Supply a connection
string through `PG_CONNECTION_STRING` and use one of libpq's credential mechanisms,
such as `PGPASSWORD` or a protected PostgreSQL password file.

```json
{
  "mcpServers": {
    "age_manager": {
      "command": "age_mcp_server",
      "env": {
        "PG_CONNECTION_STRING": "host=db.example port=5432 dbname=postgres user=age_reader sslmode=require",
        "PGPASSWORD": "replace-with-a-secret"
      }
    }
  }
}
```

Treat the MCP client configuration as a secret if it contains `PGPASSWORD`. A
PostgreSQL password file or the client's secret store is preferable.

The connection string can still be supplied explicitly when necessary:

```bash
age_mcp_server --pg-con-str "host=db.example dbname=postgres user=age_reader sslmode=require"
```

For Microsoft Entra authentication to Azure Database for PostgreSQL, first sign in
with the Azure CLI, then opt in …
