mtb (Make the Bed)

mtb is an MCP server that intends to help agents and engineers look before they leap by leveraging existing battle-tested solutions so the focus can remain on the problem at hand.

• search: Search for existing libraries rather than reinventing the wheel
• stats: Track complexity costs to keep maintenance costs from ballooning
• deps: Know what's already in your project before adding more

In a Calvin and Hobbes strip, Calvin's mom tells him to make his bed. Rather than just do it, he spends the entire day building a robot to make the bed for him. The robot doesn't work, the bed never gets made, and Calvin is more exhausted than if he'd just done it himself.

Most of the energy that goes into software is spent on debugging and maintenance. Metrics such as cyclomatic complexity and COCOMO are the subject of much debate but they do give engineers a rough idea of how much it would have cost to build and therefore maintain the software on which they are working.

AI agents will happily generate a bug-filled JSON parser from scratch when you already have three in your dependencies, or add a new HTTP client library when one is sitting right there in your lock file. And, if you ask it to build a rocketship when a perfectly cromulent open source rocketship is there for the taking, AI will happily help you build a new one.

The hope is that, rather than fixing bugs or going down rabbit holes in bespoke implementations, mtb can help agents and engineers focus on the actual problem they are trying to solve: making the bed, and externalize some of the maintenance costs which can be massive for software.

Tools

These tools are intended for use by AI agents.

stats

Analyzes code in a directory using scc. Returns lines of code, comments, blanks, complexity, and COCOMO cost estimates per language.

Parameters:

• path - directory or file to analyze
• cocomo - include COCOMO cost estimates (default: true)
• complexity - include complexity metrics (default: true)
• exclude_dir - directories to exclude from analysis
• exclude_ext - file extensions to exclude (e.g. min.js)
• include_ext - only include these file extensions

deps

Scans a directory for dependencies using Syft. Returns all detected packages with name, version, type, and language. Supports 40+ ecosystems including npm, pip, go modules, cargo, maven, gems, and more.

Parameters:

• path - directory to scan
• details - include line count and complexity per dependency (default: false)

search

Searches GitHub for existing libraries, tools, and frameworks. Use this before writing new code to check if a battle-tested solution already exists. Returns repositories sorted by stars with descriptions, URLs, and topics.

Parameters:

• query - search query describing what you need (e.g. "json schema validator python")
• language - filter by programming language (e.g. "go", "python", "javascript")
• max_results - maximum number of results to return (default: 10, max: 25)

Set GITHUB_TOKEN for higher rate limits (30 req/min authenticated vs 10 req/min unauthenticated).

Install

Download the binary for your platform from the latest release and place it somewhere on your $PATH.

Claude Code

Add to .claude/mcp.json in your project (or ~/.claude/mcp.json globally):

{
  "mcpServers": {
    "mtb": {
      "type": "stdio",
      "command": "mtb"
    }
  }
}

Cursor

Add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "mtb": {
      "command": "mtb"
    }
  }
}

Windsurf

Add to ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "mtb": {
      "command": "mtb"
    }
  }
}

VS Code (Copilot)

Add to .vscode/mcp.json in your workspace:

{
  "servers": {
    "mtb": {
      "type": "stdio",
      "command": "mtb"
    }
  }
}

Cline

Open Cline settings in VS Code, click "MCP Servers", then "Configure MCP Servers" and add:

{
  "mcpServers": {
    "mtb": {
      "command": "mtb"
    }
  }
}

OpenAI Codex

Add to ~/.codex/config.toml (or .codex/config.toml in your project):

[mcp_servers.mtb]
command = "mtb"

Gemini CLI

Add to ~/.gemini/settings.json (or .gemini/settings.json in your project):

{
  "mcpServers": {
    "mtb": {
      "command": "mtb"
    }
  }
}

Build from source

go install github.com/dbravender/mtb@latest

Eating its own dog food

Running mtb on itself:

stats:

Estimated cost: $21,316 | People: 0.59 | Schedule: 3.2 months

deps: 573 packages detected

mtb ships with 573 transitive Go modules — nearly all from Syft, which brings in container runtimes, cloud SDKs, and archive format parsers to support 40+ package ecosystems. This is mtb practicing what it preaches: 5 source files, 300 lines of production code, covering every ecosystem from npm to RPM by building on top of existing tools rather than reinventing them.

search: "MCP code analysis" — 346 results, but focused on code graphs, SAST, and security scanning. None combining dependency awareness, complexity metrics, and existing solution search. Looks like the bed needed making. If you are aware of other tools like this, please let me know!
