# PostgreSQL Connection String Parser MCP for AI Agents MCP

> PostgreSQL Connection String Parser breaks down complex database URIs into readable parts. It stops your AI agent from guessing at hostnames or ports by extracting the exact username, password, and network settings directly from the string.

## Description

Dealing with database connection strings is a headache when you are trying to automate tasks. One wrong character in a URI can break your entire pipeline. This MCP takes that guesswork out of the equation. Instead of letting an agent try to figure out where your database lives, it pulls every piece of information, like the host, port, and database name, with total precision. You can also check if your network settings are actually valid or even see which authentication methods are active for a specific user. It is like having a specialized tool that reads the fine print so you do not have to. Since this is part of the Vinkius catalog, you can just connect it to your preferred client and start parsing strings immediately without any complex setup.

## Tools

### parse_connection_string
Breaks a PostgreSQL URI into its individual parts like host and port.

### validate_port_configuration
Checks if your provided port and host settings are technically valid.

### identify_auth_mechanisms
Finds the specific security protocols used for your database login.

## Prompt Examples

**Prompt:** 
```
Can you break down this connection string for me? postgresql://db_admin:secret@localhost:5432/production_db
```

**Response:** 
```
| Parameter | Value |
| :--- | :--- |
| **Username** | `db_admin` |
| **Password** | `secret` |
| **Host** | `localhost` |
| **Port** | `5432` |
| **Database** | `production_db` |
```

**Prompt:** 
```
Is this port configuration okay for my database host? db.internal.net:70000
```

**Response:** 
```
No, that port is invalid. The value **70000** exceeds the maximum allowed port limit of 65535. You should use a port within the standard range.
```

**Prompt:** 
```
What kind of authentication is this string using? postgresql://user@localhost/db
```

**Response:** 
```
The connection string uses **Trust-based** authentication, as no password was provided in the URI.
```

## Capabilities

### Extract URI components
Pulls username, password, host, and database name from a single string.

### Check network settings
Confirms if the port and host configuration is actually valid.

### Audit authentication
Identifies which security methods are being used for a connection.

## Use Cases

### Broken deployment
A developer pastes a new URI into Cursor and asks the agent to check it. The parsing reveals a typo in the port.

### Security audit
An engineer needs to know if a specific string uses password-based or trust-based auth. The tool provides the answer.

### Network troubleshooting
A DevOps pro asks their agent if a host is reachable via a specific port. The system flags an invalid port number.

## Benefits

- Stop guessing: Get exact host and port details every time.
- Prevent connection errors: Catch bad network settings before they break your app.
- Secure your access: Quickly check security protocols for any string.
- Eliminate hallucinations: Ensure your agent never invents a fake database username or host.
- Speed up debugging: Get an instant breakdown of complex, encoded connection strings.

## How It Works

The bottom line is you get error-free database credentials every time.

1. Paste your PostgreSQL URI into your AI client
2. The MCP applies strict regex patterns to deconstruct the string
3. You get back a clean breakdown of every connection parameter

## Frequently Asked Questions

**How can I use the PostgreSQL Connection String Parser to avoid errors?**
It extracts every part of your URI, like host and port, with precision so your agent does not guess wrong.

**Does the PostgreSQL Connection String Parser work with any AI client?**
Yes, you can connect it to Claude, Cursor, or Windsurf through Vinkius to start parsing strings immediately.

**Can the PostgreSQL Connection String Parser help me find security issues?**
It allows your agent to identify which authentication mechanisms are active in a given connection string.

**Will the PostgreSQL Connection String Parser catch bad port numbers?**
Yes, it can validate whether a port configuration is technically valid before you try to use it.

**Is the PostgreSQL Connection String Parser useful for debugging?**
Absolutely. It breaks down complex, encoded URIs into clear, readable parameters like username and database name.

**What does `parse_connection_string` return?**
It returns a structured object containing the username, password, host, port, and database name extracted from the URI.

**How does it handle URL-encoded passwords?**
The parser automatically decodes URL-encoded characters in the password field to ensure you get the actual plain-text credential.

**Can I validate if a port is within the allowed range?**
Yes, use the `validate_port_configuration` tool to check if the extracted port is a valid number between 1 and 65535.
