wcgw
Shell and coding agent on claude desktop app
Stars: 94
wcgw is a shell and coding agent designed for Claude and Chatgpt. It provides full shell access with no restrictions, desktop control on Claude for screen capture and control, interactive command handling, large file editing, and REPL support. Users can use wcgw to create, execute, and iterate on tasks, such as solving problems with Python, finding code instances, setting up projects, creating web apps, editing large files, and running server commands. Additionally, wcgw supports computer use on Docker containers for desktop control. The tool can be extended with a VS Code extension for pasting context on Claude app and integrates with Chatgpt for custom GPT interactions.

- Claude - An MCP server on claude desktop for autonomous shell and coding agent. (mac only)
- Chatgpt - Allows custom gpt to talk to your shell via a relay server. (linux or mac)
-
[9 Dec 2024] Vscode extension to paste context on Claude app
-
[01 Dec 2024] Removed author hosted relay server for chatgpt.
-
[26 Nov 2024] Introduced claude desktop support through mcp
- ⚡ Create, Execute, Iterate: Ask claude to keep running compiler checks till all errors are fixed, or ask it to keep checking for the status of a long running command till it's done.
- ⚡ Large file edit: Supports large file incremental edits to avoid token limit issues. Faster than full file write.
- ⚡ Syntax checking on edits: Reports feedback to the LLM if its edits have any syntax errors, so that it can redo it.
- ⚡ Interactive Command Handling: Supports interactive commands using arrow keys, interrupt, and ansi escape sequences.
- ⚡ Full Shell Access: No restrictions, complete control.
- Solve problem X using python, create and run test cases and fix any issues. Do it in a temporary directory
- Find instances of code with X behavior in my repository
- Git clone https://github.com/my/repo in my home directory, then understand the project, set up the environment and build
- Create a golang htmx tailwind webapp, then open browser to see if it works (use with puppeteer mcp)
- Edit or update a large file
- In a separate branch create feature Y, then use github cli to create a PR to original branch
- Command X is failing in Y directory, please run and fix issues
- Using X virtual environment run Y command
- Using cli tools, create build and test an android app. Finally run it using emulator for me to use
- Fix all mypy issues in my repo at X path.
- Using 'screen' run my server in background instead, then run another api server in bg, finally run the frontend build. Keep checking logs for any issues in all three
- Create repo wide unittest cases. Keep iterating through files and creating cases. Also keep running the tests after each update. Do not modify original code.
First install uv
using homebrew brew install uv
(Important: use homebrew to install uv. Otherwise make sure uv
is present in a global location like /usr/bin/)
Then update claude_desktop_config.json
(~/Library/Application Support/Claude/claude_desktop_config.json)
{
"mcpServers": {
"wcgw": {
"command": "uv",
"args": [
"tool",
"run",
"--from",
"wcgw@latest",
"--python",
"3.12",
"wcgw_mcp"
]
}
}
}
Then restart claude app.
If there's an error in setting up
- If there's an error like "uv ENOENT", make sure
uv
is installed. Then run 'which uv' in the terminal, and use its output in place of "uv" in the configuration. - If there's still an issue, check that
uv tool run --from wcgw@latest --python 3.12 wcgw_mcp
runs in your terminal. It should have no output and shouldn't exit. - Debug the mcp server using
npx @modelcontextprotocol/[email protected] uv tool run --from wcgw@latest --python 3.12 wcgw_mcp
Wait for a few seconds. You should be able to see this icon if everything goes right.
Then ask claude to execute shell commands, read files, edit files, run your code, etc.

patchwork
PatchWork is an open-source framework designed for automating development tasks using large language models. It enables users to automate workflows such as PR reviews, bug fixing, security patching, and more through a self-hosted CLI agent and preferred LLMs. The framework consists of reusable atomic actions called Steps, customizable LLM prompts known as Prompt Templates, and LLM-assisted automations called Patchflows. Users can run Patchflows locally in their CLI/IDE or as part of CI/CD pipelines. PatchWork offers predefined patchflows like AutoFix, PRReview, GenerateREADME, DependencyUpgrade, and ResolveIssue, with the flexibility to create custom patchflows. Prompt templates are used to pass queries to LLMs and can be customized. Contributions to new patchflows, steps, and the core framework are encouraged, with chat assistants available to aid in the process. The roadmap includes expanding the patchflow library, introducing a debugger and validation module, supporting large-scale code embeddings, parallelization, fine-tuned models, and an open-source GUI. PatchWork is licensed under AGPL-3.0 terms, while custom patchflows and steps can be shared using the Apache-2.0 licensed patchwork template repository.

baml
BAML is a config file format for declaring LLM functions that you can then use in TypeScript or Python. With BAML you can Classify or Extract any structured data using Anthropic, OpenAI or local models (using Ollama) ## Resources ![](https://img.shields.io/discord/1119368998161752075.svg?logo=discord&label=Discord%20Community) [Discord Community](https://discord.gg/boundaryml) ![](https://img.shields.io/twitter/follow/boundaryml?style=social) [Follow us on Twitter](https://twitter.com/boundaryml) * Discord Office Hours - Come ask us anything!

Define what your LLM output type is in a .baml file, with rich syntax to describe any field (even enum values) 2. Declare your prompt in the .baml config using those types 3. Add additional LLM config like retries or redundancy 4. Transpile the .baml files to a callable Python or TS function with a type-safe interface. (VSCode extension does this for you automatically). We were inspired by similar patterns for type safety: protobuf and OpenAPI for RPCs, Prisma and SQLAlchemy for databases.
