DevHub 2.0

This update focuses on removal of the prior ai-harness scaffolding in favor of a focused, practical tool.

Highlights

DevHub MCP Server (devhub-mcp)

A new read-only MCP server exposing your entire DevHub catalog as AI-editor tools. Runs locally at 127.0.0.1:47821 and provides 9 tools:

Tool Description
list_projects Catalog of all projects with metadata
project_overview README, layout, git state, recent commit, todos
list_tree Gitignore-aware file tree (depth/hidden controls)
read_file Read line ranges of text files with editor-navigable paths
search_content Full-text search across project files
git_status Live branch, upstream, ahead/behind, changed-file stats
git_diff Unified diffs, optionally filtered by path
git_log Commit history pages
list_todos Per-project DevHub todo items

How to Use

There are two ways to connect DevHub to your editor:

Option A: Standalone (stdio): build the binary with cargo build --release -p devhub-mcp and add it as a local MCP server in your editor:

"devhub-mcp": {
      "enabled": true,
      "remote": false,
      "command": "/path/to/executable",
      "args": [],
      "timeout": 30
    },

Option B: DevHub HTTP (Streamable HTTP): toggle the MCP switch inside the DevHub desktop app, then point your editor to the running server:

"devhub-mcp": {
      "type": "remote",
      "url": "http://127.0.0.1:47821/mcp"
    }
  }

Todo List

Lightweight per-project todo tracking accessible via devhub-mcp list_todos and the in-editor todo panel.

Artifacts

  • Windows x64
  • Linux x64
  • macOS Apple Silicon

Each archive contains the executable, README.md, RELEASE.md, and LICENSE. SHA-256 hashes are published in checksums.txt.

Requirements

  • Git for repository workflows.
  • OpenSSH configuration and key-based authentication for SSH projects.
  • A POSIX remote environment with standard command-line tools.
  • Linux requires a glibc-based system and a Vulkan-capable desktop stack.
  • The macOS build is an unsigned portable binary, not a notarized app bundle.

Before running an archive, compare its SHA-256 hash with checksums.txt.
