What is dbgagent?

dbgagent is a tool that helps you with any code. Here's what it does:

1. Fix — Run a broken script, catch the error, explain it, and fix it automatically
2. Explain — Understand what any code does, line by line
3. Simplify — Make code shorter and cleaner without changing behavior
4. Review — Find bugs, bad practices, and improvements
5. Test — Generate unit tests for your code
6. Secure — Find security vulnerabilities
7. Optimize — Find performance bottlenecks
8. Convert — Convert code between programming languages
9. Doc — Generate documentation for your code

Works with any programming language — Python, JavaScript, Go, Rust, Java, C++, and more.

How to install

Open your terminal and type:

pip install dbgagent

That's it. One command.

Install with MCP support

If you want to use MCP servers (connect to databases, external tools, etc.):

pip install "dbgagent[mcp]"

---

How to upgrade

Upgrade to latest version

pip install --upgrade dbgagent

Force reinstall latest version

If something is broken, force a fresh install:

pip install --force-reinstall --no-cache-dir dbgagent

Install a specific version

pip install dbgagent==0.6.0

---

How to uninstall

pip uninstall dbgagent

That's it. One command. Your config files (.dbgagent.json) are NOT deleted — they stay in your project folder.

---

How to set up

You need a free API key from Groq (this is what powers the AI):

1. Go to console.groq.com and sign up (free)
2. Copy your API key
3. When you first run dbgagent, it will ask you to paste your key

What happens when you debug a script?

Here's what you'll see:

$ dbgagent run myscript.py

Running: myscript.py

Script failed (exit 1)

Adding MCP servers (advanced)

MCP servers give dbgagent extra information to make better fixes. For example, if your script uses a database, dbgagent can check your database structure to understand the error better.

Adding a server

Type this in your terminal:

dbgagent add

It will ask you:

1. Server name — just a label (like "mydatabase")
2. Type — URL (if your server has a web address) or command (if it runs locally)
3. Triggers — words that tell dbgagent when to use this server (like "sql,database")

Example:

Server name: mydatabase
Type: 1 (URL)
URL: http://localhost:8000/sse
Triggers: sql,database,postgres

Server 'mydatabase' added!

Viewing your servers

dbgagent list

Removing a server

dbgagent remove

Editing the config file

Settings

To see your current setup:

dbgagent settings

This shows:

• Which AI provider you're using
• If your API key is set
• How many MCP servers you have

What can dbgagent do?

Debug any language

Catches errors in any programming language and fixes them automatically.

Explain code

Paste any code and get a clear explanation of what it does, line by line.

Simplify code

Take working but complex code and make it shorter and cleaner.

Review code

Find bugs, security issues, performance problems, and bad practices.

---

Examples

Fix a broken script

dbgagent fix myscript.py

Explain any code

dbgagent explain app.js

Simplify any code

dbgagent simplify utils.go

Review any code

dbgagent review main.rs

Generate tests

dbgagent test calculator.py

Security scan

dbgagent secure auth.py

Performance analysis

dbgagent optimize slow.py

Convert between languages

dbgagent convert main.py --to javascript

Generate documentation

dbgagent doc helpers.py

---

Troubleshooting

"API key not set"

Run dbgagent and choose P (Settings) to check your setup.

"No .py files found"

Make sure you're in the folder that contains your Python script.

"MCP package not installed"

If you want to use MCP servers, install with:

pip install "dbgagent[mcp]"

---

Who is this for?

• Students — learn any programming language faster with AI explanations
• Developers — debug, review, and clean up code quickly
• Data scientists — fix scripts and understand complex pipelines
• Anyone who writes code — no more searching Stack Overflow for error messages

---

How the retry works

dbgagent doesn't give up after one failed fix. Here's what happens:

1. First fix is tested in a safe temporary folder
2. If it fails, the error is saved
3. dbgagent tries again, using the previous error to learn what went wrong
4. This happens up to 3 times
5. If all 3 fixes fail, no changes are made to your file

Your original file is never modified until you say "yes" to apply the fix.

---

Config file format

When you add MCP servers, dbgagent creates a .dbgagent.json file in your project folder. Here's what it looks like:

{
  "mcp_servers": {
    "mydatabase": {
      "url": "http://localhost:8000/sse",
      "triggers": ["sql", "database", "postgres"]
    },
    "myfiles": {
      "command": "npx",
      "args": ["@modelcontextprotocol/server-filesystem", "."],
      "triggers": ["file", "directory", "path"]
    }
  }
}

Two ways to connect to a server:

• URL — if your server has a web address (like http://localhost:8000/sse)
• Command — if it runs locally (like npx @modelcontextprotocol/server-postgres)

Triggers are words that tell dbgagent when to use that server. For example, if your error mentions "sql" or "database", dbgagent will query your database server for more information.

Using dbgagent with other AI tools

dbgagent can also work as a server that other AI tools can call. This means you can use dbgagent inside Claude Desktop, Cursor, or opencode.

Run the MCP server

dbgagent-mcp

This starts dbgagent as a server that other AI tools can connect to.

Claude Desktop setup

Add this to your Claude Desktop config file (claude_desktop_config.json):

{
  "mcpServers": {
    "dbgagent": {
      "command": "dbgagent-mcp"
    }
  }
}

Cursor / opencode setup

Add this to your opencode.json:

{
  "mcpServers": {
    "dbgagent": {
      "command": "dbgagent-mcp"
    }
  }
}

Once set up, you can ask Claude or Cursor to debug Python scripts, and they'll use dbgagent automatically.
