Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "bach-codecommander": {
      "command": "npx",
      "args": [
        "-y",
        "bach-codecommander-mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add bach-codecommander -- npx -y bach-codecommander-mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "bach-codecommander": {
      "command": "npx",
      "args": [
        "-y",
        "bach-codecommander-mcp"

Common questions

Is BACH CodeCommander safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.3.0) reached the registry 9 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

ellmos CodeCommander MCP Server

The README navigation lists the available documentation languages. Section 11 separately describes the runtime languages used for tool output messages and diagnostics. This does not claim that MCP discovery or schema descriptions, the GUI, CLI, or API are translated.

*Part of the ellmos-ai family.*

[!NOTE]

For AI Assistants & LLMs: Machine-readable indexing documentation for this repository is available at llms.txt. The server exposes 23 specialized tools under the cc_ prefix.

A developer-focused Model Context Protocol (MCP) server that gives AI assistants code analysis, structural Python editing, JSON repair, encoding fix, import organization, format conversion, file diff, and regex testing capabilities.

23 tools optimized for developers - the coding companion to FileCommander.

Discoverability: Published on npm as ellmos-codecommander-mcp, visible on Glama, and prepared for the official MCP Registry with server.json under io.github.ellmos-ai/ellmos-codecommander-mcp. Registry and directory manifests server.json, glama.json, smithery.yaml, and llms.txt are maintained in full parity.

1. Overview & Highlights

While FileCommander handles filesystem operations and system processes, CodeCommander focuses specifically on code intelligence and developer precision:

Python, JavaScript & TypeScript Analysis — Extension-dispatched classes, methods, functions, complexity metrics, and import analysis; JS/TS analysis is regex-based and read-only.
BACH-derived Python Helpers — Runtime import diagnostics, structural edits, indentation checks, and template-based code generation.
Explicit Language Gates — Python-only path tools reject non-.py files explicitly instead of producing Python-shaped false findings.
JSON Repair & Validation — Automatically repair broken JSON (trailing commas, single quotes, BOM, comments) with precise error locations.
PEP 8 Import Organization — Sort and deduplicate Python imports per PEP 8 guidelines.
Encoding & Mojibake Repair — Fix Mojibake and double-encoded UTF-8 (27+ patterns) and broken German characters (70+ umlaut patterns).
Universal Format Conversion — Convert between JSON, CSV, INI, YAML, TOML, XML, and TOON formats losslessly.
Unified File Diff — Compare two files with LCS unified diff output and configurable context lines.
Regex Testing Workbench — Test regular expressions with match details, capturing groups, and replace previews.
Markdown Export — Convert Markdown to standalone HTML or PDF with syntax-styled code blocks, tables, and blockquotes.
Cross-Platform Native — Full support on Windows, macOS, and Linux.

2. Target Personas & Discoverability

CodeCommander MCP is engineered to address key bottlenecks in modern autonomous AI coding, local multi-agent swarms, and safety-compliant developer tooling:

Target Audience & Stakeholder Personas

`[PERSONA-01]` (`[PERSONA-1]`) Autonomous AI Coding Agents & LLM Pair-Programmers
Profile: Agents such as Claude Code, Antigravity, Codex, Cursor, and Windsurf performing automated code refactoring, test repair, and feature development.
Pain Point: Standard LLM code outputs frequently suffer from hallucinated imports, broken indentation in complex Python control flows, invalid JSON configs, or syntax corruption during naive chunk edits.
Solution: Native AST extraction (cc_extract_classes, cc_analyze_methods), preview-safe structural editing with unified diffs (cc_python_structural_edit), automatic indentation checking (cc_check_indentation), and deterministic JSON repair (cc_fix_json).

`[PERSONA-02]` (`[PERSONA-2]`) Full-Stack & Python/TypeScript Software Engineers
Profile: Developers maintaining polyglot projects, CLI utilities, and data pipelines requiring cross-language AST analysis and rapid configuration format transitions.
Pain Point: Tedious manual format conversions (JSON ↔ YAML ↔ TOML ↔ TOON ↔ XML), broken German umlauts or Mojibake from legacy encodings, and circular runtime imports.
Solution: Universal format converter (cc_convert_format), non-destructive encoding and umlaut repair (cc_fix_encoding, cc_fix_umlauts), isolated runtime import diagnostics (cc_runtime_import_diagnose), and interactive regex tester (cc_regex_test).

`[PERSONA-03]` (`[PERSONA-3]`) Enterprise AI Safety, SecOps & Code Governance Officers
Profile: Security auditors, compliance engineers, and enterprise architects evaluating MCP toolchains for developer workstations and CI/CD runners.
Pain Point: Risk of confidential code leakage via cloud telemetry, unauthorized process elevation, or destructive in-place file overwrites by AI assistants.
Solution: 100% Zero-Egress local stdio transport (INV-LOCAL-01), unprivileged user-space execution (INV-SEC-02), mandatory timestamped .bak backups before mutations (INV-BAK-04), dry-run diff preview safety (INV-PREV-03), and isolated subprocess timeouts (INV-ISOL-05).

`[PERSONA-04]` (`[PERSONA-4]`) Open-Source Ecosystem Architects & MCP Tool Developers
Profile: Maintainers building, publishing, and indexing MCP servers across Glama, Smithery, npm, and GitHub.
Pain Point: Fragmented directory manifests, missing third-party license disclosures, and lack of machine-readable indexing context for AI agents.
Solution: 100% manifest parity across package.json, server.json, glama.json, smithery.yaml, and llms.txt, verified by automated contract tests and a complete open-source license audit (THIRD_PARTY_LICENSES.md).

3. Comparative Matrix vs. Alternatives

The following matrix compares CodeCommander MCP against alternative developer tooling approaches across 10 critical operational dimensions:

Dimension / Capability	Generic File MCP	Raw Shell / Ad-Hoc Scripts	Heavyweight Cloud LLMOps	Traditional IDE Plugins	ellmos CodeCommander MCP
1. AST Code Intelligence	None (raw text reads)	Requires custom python scripts	Cloud parser required	Built-in (GUI only)	Native AST & regex JS/TS (`cc_analyze_code`)
2. Safe Structural Edit Preview	None (blind overwrite)	High risk (`sed`/`awk`)	Cloud gateway dependent	Interactive dialog	Preview-safe diffs (`mode: "preview"`)
3. Mandatory Pre-Mutation Backups	None	Manual scripting	None	Local history (opaque)	Automatic `.bak` creation (`INV-BAK-04`)
4. Runtime Import Diagnostics	None	Unsafe direct execution	None	Partial / static only	Isolated subprocess + timeout (`INV-ISOL-05`)
5. Encoding & Mojibake Recovery	None	Fragile `iconv` calls	None	Basic encoding switch	27+ Mojibake, 70+ Umlauts (`cc_fix_encoding`)
6. Universal Format Conversion	None	Multiple disparate CLI tools	SaaS conversion API	Multi-plugin setup	Lossless 7 formats (`JSON/YAML/TOML/XML/TOON`)
7. Diff Engine & Regex Workbench	None	Basic `diff`/`grep`	None	GUI panel only	LCS Unified Diff & Regex with groups/replace
8. Local-First & Zero-Egress	Host-dependent	Local	Cloud egress / telemetry	Often connects to cloud	100% Offline Stdio JSON-RPC (`INV-LOCAL-01`)
