GitWand MCP server

GitWand is a lightweight, native Git client built with Tauri 2 and Vue 3. It covers the full daily workflow — changes, history, branches, push/pull — and goes further with automatic resolution of trivial merge conflicts, integrated PR code review with inline comments, and a Git Tree as the primary history view. Since v1.3, AI assists every step of the workflow — branch naming, PR writing, hunk-level review, semantic squash, and natural-language commit search. v2.7+ adds multi-repo Workspaces and Worktrees; v2.8 adds Agent Sessions (MCP); v2.9 adds a cross-repo Launchpad; v2.10 brings multi-forge pull requests across GitHub, GitLab, Bitbucket and Azure DevOps; v2.13 adds inline AI code review; v2.18 overlays CI check annotations directly on the diff; v2.19 adds OAuth device-flow sign-in for GitHub and Azure DevOps (no gh CLI required) plus cross-fork pull requests. The 3.x line makes GitWand a daily driver for AI-assisted work: v3.0 turns the cross-repo dashboard into Today, a triaged action inbox, and publishes the VS Code extension on the Marketplace; v3.2 adds an integrated terminal with AI agent tabs — including one-click AI tasks in isolated worktrees — and a dockable File Explorer / Editor panel. v3.11 makes the Conflict Predictor run the merge it predicts and adds Gitea and Forgejo; v3.12 brings GitWand's own terminal emulator, a WIP row in the Git Tree and AI agents kept away from your tokens; v3.13 turns worktrees into environments — per-repo setup and teardown commands, merge-back of an agent's work as a merge, rebase or squash, and removed worktrees restorable from the Time Machine.

Desktop app

Git Tree

The Git Tree is the primary history view — a full-resolution DAG that renders the branch topology as an SVG with trunk-pinning, lane cooldowns, WIP node, and ref badges. Click any commit to see its diff; right-click to checkout, reset, branch, tag, or cherry-pick. Branches, stashes, and tags are all managed from here without a separate panel. A filter mode (v3.2) recalculates the DAG to show only matching commits, with quick branch/author toggles, date-bucket separators, branch-name autocomplete, and #<PR number> lookup that resolves straight to the PR's branch.

Repository view

Staged, unstaged, untracked, and conflicted files in a sidebar with inline diffs in the main area. Stage, unstage, discard, and commit without leaving the interface. Partial staging at the line or hunk level.

Commit workflow

Summary + description fields, optional commit signature, Ctrl+Enter shortcut. Unpushed commits can be amended directly from the Git Tree — a pencil icon appears on hover, opening an overlay pre-filled with the existing message.

Branches

Click the branch name in the header to search, switch, create, or delete branches. Merge any branch from the dedicated merge button. Each non-current branch shows a merge preview button that simulates the merge result before committing.

Merge preview

Before merging a branch, GitWand predicts the outcome without touching the working tree — using git merge-base, git show, and git merge-file -p --diff3. The result shows a per-file breakdown:

• Auto-resolvable — GitWand can handle it automatically
• Partial — some hunks need manual resolution
• Manual — complex conflicts requiring human judgment
• Add/delete — file added on one side, deleted on the other

A badge summarises the overall result: Clean merge, 100% auto-resolvable, or N conflicts to review.

Push & Pull

One-click push and pull with badge counters showing ahead/behind commits. Auto-fetch runs in the background every 30 seconds.

Diff viewer

Side-by-side or inline toggle, persisted across sessions. Syntax highlighting for 30+ languages, word-level diff using LCS, collapsible unchanged regions, canvas minimap, hunk navigation (prev/next), double-column line numbers.

File history & blame

Full file history with git log --follow, blame view grouped by commit, time-travel diff between any two versions of a file.

Repo switcher & Workspaces

The current repo name in the header opens a dropdown showing recently opened repositories. Pin favourites, switch instantly — no file picker needed. Workspaces (v2.7) group multiple repos into a single dashboard with cross-repo status, coordinated push/pull, and quick-create worktrees (⌘⇧N). Each project tab carries a worktree submenu (v3.2) listing main plus every worktree — select one to switch that project's checkout in place, no extra tab.

Today

Today (⌘L; introduced as Launchpad in v2.9, reworked in v3.0) is a cross-repo triaged action inbox: everything in flight — WIP, PRs, Issues, Team — sorted into urgency tiers, each row carrying a state-aware primary action (Merge · Review · Resolve · Reply · See failure). Pin or snooze any item; the Team tab loads lazily for performance on large workspaces.

Pull Requests & Code Review

Browse, create, checkout, and merge pull/merge requests across GitHub, GitLab, Bitbucket, Azure DevOps, Gitea and Forgejo without leaving the app. GitWand auto-detects the forge from the remote and routes to the right provider; accounts are managed once in Settings. The PR list sits in the sidebar and the full detail — diff, CI checks, comments, inline review — fills the main area.

• Sign in with OAuth — "Sign in with GitHub" and "Sign in with Azure DevOps" use the OAuth device flow; tokens are stored in the OS keychain and the GitHub PR workflow runs tokenless over the REST API, with no gh CLI required (the CLI path still works when no token is configured)
• Cross-fork pull requests — when origin is a fork, open a PR straight against the upstream parent (default), and see the PRs you opened upstream listed alongside your fork's own
• Inline comments — read and write review comments anchored to diff lines, with full threading and code suggestions (```suggestion ``` blocks applicable in one click)
• Inline CI check annotations — failed-check annotations overlay the diff with gutter icons (❌/⚠/ℹ) and hover tooltips, with a per-file count in the sidebar (GitHub, GitLab and Bitbucket)
• Review submission — Approve / Request changes / Comment, with a draft queue to accumulate comments before sending
• 🧠 Intelligence panel — conflict prediction (git merge-tree before merging), hotspot analysis, review scope, static AI suggestions, file review history

Agent Sessions

The Agents panel (v2.8) shows active MCP sessions and lets you launch Claude Code directly from GitWand — the agent's changes appear live in the diff viewer. The MCP catalog (Settings > MCP) lets you install any MCP server in one click.

Integrated terminal & AI tasks

The terminal panel (v3.2) renders through WebGL with inline search (Ctrl+F), clickable links, and typed tabs — shell, claude, codex — each with its own icon and an unread-output dot. "Launch Claude Code" / "Launch Codex" open a real PTY tab, and "New AI task" creates a scratch git worktree and opens a Claude Code tab in it in one click — the agent works in isolation, and when it's done you either merge the work back or delete the worktree from the project tab's submenu. Hardened with a shell-executable whitelist, safe_repo_path() on all filesystem operations, and PTY orphan prevention.

File Explorer / Editor

A dockable Files panel (v3.2, drag/resize/fullscreen) lists the full repo tree — gitignore-aware, via git ls-files — and opens files in a lazy-loaded CodeMirror 6 editor with syntax highlighting, per-tab undo history, and a lock/undo/save toolbar. Reachable from the Files tile in the AppDock, with per-repo layout settings.

Settings

Language (English, French, Spanish, Brazilian Portuguese, Simplified Chinese — OS auto-detected), theme (dark/light/system), commit signature, diff mode, external editor, Git binary path, and switch behavior (stash/ask/refuse). AI providers cover API backends (Claude / OpenAI-compatible / Ollama) and local CLI agents (Claude Code, Codex, opencode, GitHub Copilot CLI), each with its own model picker. Accounts manages forge sign-in — OAuth device flow for GitHub and Azure DevOps, App Passwords / CLI for the others. All persisted in app settings.

Conflict resolution engine

GitWand's core engine (@gitwand/core) automatically resolves trivial Git merge conflicts. It never touches complex or ambiguous hunks.

Resolution patterns

GitWand uses a pattern registry — the classifier evaluates patterns in priority order, each declaring whether it requires diff3 (base available), diff2, or works on both.

The registry holds 12 patterns, of which 8 auto-apply. The other four either propose a resolution you confirm, are opt-in, or hand the hunk back untouched.

Pattern	Priority	Auto-applies	Description	Typical confidence
same_change	10	Yes	Both branches made the exact same edit	Certain
delete_no_change	20	Yes	One side deleted the block, the other left it untouched	Certain
one_side_change	30	Yes	Only one branch modified the block	Certain
non_overlapping	40	Yes	Additions at different locations in the block	High
whitespace_only	50	Yes	Same logic, different indentation/spacing	High
reorder_only	55	Yes	Same lines, different order, a pure permutation	High
insertion_at_boundary	57	Yes	Pure insertions on both sides, base intact	High
value_only_change	60	Yes	Both sides changed the same scalar (version, hash, timestamp)	High to medium
token_level_merge	65	No, proposes	Disjoint token edits on the same line, merged into a proposal you confirm	Medium
refactoring_aware_merge	970	No, opt-in	Rename or move detected and replayed across the conflict	High
llm_proposed	998	No, opt-in	Model-proposed resolution, validated post-merge	Medium
complex	999	No	Overlapping edits, always surfaced with a full trace	Low

The confidence column is indicative: every hunk carries a computed ConfidenceScore (see below), not a fixed label. value_only_change, for instance, scores on the ratio of volatile tokens to total tokens and rejects the hunk outright below its threshold.

Not a registry pattern: generated_file is a separate reclassification pass that runs after classification. When a hunk's path matches a generated-file glob (lockfiles, bundles, dist/, plus anything in generatedFiles), the resolver rewrites it to generated_file and, by default, declines with an actionable reason rather than guessing — measured on 1,662 real merges, auto-merging generated files diverged from what teams actually shipped in almost every case. GitWand tells you to resolve the source file and re-run the installer/build instead. Opt back into the old accept-theirs/semantic-merge behavior with .gitwandrc's resolveGeneratedFiles: true or gitwand resolve --resolve-generated. generated_file appears in ConflictType but never in the classifier registry.

Composite confidence score

Every resolution carries a ConfidenceScore object rather than a simple label:

{
  score: 84,           // 0–100 composite score
  label: "high",       // "certain" | "high" | "medium" | "low"
  dimensions: {
    typeClassification: 90,  // certainty of the detected pattern
    dataRisk: 20,            // risk of data loss if auto-resolved
    scopeImpact: 10,         // impact of change size
  },
  boosters: ["Path matches generated-file pattern: lockfile"],
  penalties: ["Content will be regenerated — theirs assumed more recent"],
}

(Shape shown for a generated_file hunk with resolveGeneratedFiles: true — the default is to decline generated files rather than score and apply them; see the pattern table above.)

Score formula: score = typeClassification − dataRisk×0.4 − scopeImpact×0.15

Format-aware resolvers

For structured files, GitWand uses semantic resolvers before falling back to text matching:

• JSON / JSONC — recursive key-by-key merge using JSON.parse/JSON.stringify. Handles nested objects, detects unresolvable scalar conflicts, strips comments in .jsonc.
• Markdown — section-aware merge by ATX heading (H1–H6). Merges independent sections, falls back to text if the same section is modified on both sides.

Configurable merge policies

Create a .gitwandrc file at the project root to define resolution strategies:

{
  "policy": "prefer-merge",
  "patternOverrides": {
    "*.lock": "prefer-theirs",
    "src/generated/**": "prefer-theirs",
    "CHANGELOG.md": "prefer-ours"
  }
}

Available policies: prefer-ours, prefer-theirs, prefer-safety, prefer-merge, strict.

Decision trace

Every classification step is logged in a DecisionTrace for auditing and debugging:

✓ src/config.ts — 3/3 resolved
  L12 [one_side_change] certain — Only the incoming branch modified this block.
  L25 [same_change] certain — Both branches made the exact same edit.
  L41 [value_only_change:json] high — Scalar value updated on one side (version field).

CLI

# Use directly with npx
npx @gitwand/cli resolve

# Or install globally
npm install -g @gitwand/cli

gitwand resolve              # Resolve all conflicted files in the repo
gitwand resolve --dry-run    # Preview without writing
gitwand resolve --verbose    # Detailed decision trace
gitwand status               # Show conflict status per file
gitwand resolve --ci         # CI mode: JSON output + semantic exit codes

Enriched JSON output

The --ci / --json flag returns a full structured report with composite confidence scores, decision traces, and pending hunks for LLM-assisted resolution:

{
  "version": "0.1.0",
  "timestamp": "2026-04-14T12:00:00.000Z",
  "summary": {
    "files": 2,
    "totalConflicts": 5,
    "autoResolved": 4,
    "remaining": 1,
    "allResolved": false
  },
  "files": [
    {
      "path": "src/config.ts",
      "totalConflicts": 3,
      "autoResolved": 3,
      "remaining": 0,
      "validation": {
        "isValid": true,
        "hasResidualMarkers": false,
        "syntaxError": null
      },
      "resolutions": [
        {
          "line": 15,
          "type": "one_side_change",
          "resolved": true,
          "explanation": "Only one side modified this block",
          "confidence": {
            "score": 95,
            "label": "certain",
            "typeClassification": 100,
            "dataRisk": 5,
            "scopeImpact": 10
          },
          "trace": {
            "selected": "theirs",
            "hasBase": true,
            "summary": "One-side change detected — incoming accepted.",
            "steps": ["..."]
          }
        }
      ],
      "pendingHunks": []
    }
  ]
}

The pendingHunks array gives AI agents and CI scripts everything they need to handle the conflicts that GitWand can't auto-resolve — the ours/theirs/base content, the classification trace, and the confidence breakdown.

---

MCP Server

GitWand ships an MCP (Model Context Protocol) server that exposes its conflict resolution engine to AI agents — Claude Code, Claude Desktop, Cursor, Windsurf, and any MCP-compatible client.

Setup

Add this to your MCP client configuration (e.g. claude_desktop_config.json or .claude/settings.json):

{
  "mcpServers": {
    "gitwand": {
      "command": "npx",
      "args": ["-y", "@gitwand/mcp"]
    }
  }
}

The server defaults to the working directory of the client. To pin it to a specific repo, add "--cwd", "/absolute/path/to/repo" to the args array. With Claude Code, install in one line:

claude mcp add gitwand -- npx -y @gitwand/mcp

Tools

Tool	Description
gitwand_status	List conflicted files with their complexity and auto-resolvability
gitwand_resolve_conflicts	Auto-resolve trivial conflicts, return DecisionTrace + pendingHunks
gitwand_preview_merge	Dry-run resolution — stats and risk assessment without writing files
gitwand_explain_hunk	Explain why a specific hunk was classified its type (full trace + context)
gitwand_apply_resolution	Apply a custom (LLM-provided) resolution to a specific complex hunk
gitwand_resolve_hunk	Ask the connected agent to propose a resolution for one pending hunk (ours/theirs/base + trace returned)
gitwand_resolve_hunk_llm	Validate an LLM-proposed resolution through the post-merge gate, then apply it to disk

Resources

URI	Description
gitwand://repo/conflicts	Current conflict state — files, counts, types
gitwand://repo/policy	Active .gitwandrc configuration
gitwand://hunk/{file}/{line}	Raw hunk content for a specific conflict

The human ↔ LLM collaboration loop

The MCP server enables a powerful workflow where GitWand handles the trivial conflicts automatically and the LLM tackles the complex ones:

1. LLM calls gitwand_preview_merge — sees how many conflicts exist and how many GitWand can handle
2. LLM calls gitwand_resolve_conflicts — GitWand auto-resolves the easy ones, returns pendingHunks for the rest
3. LLM reads the pendingHunks — each one contains ours/theirs/base content and a full decision trace
4. LLM calls gitwand_apply_resolution for each pending hunk — writes its resolution directly

Claude Code slash commands

GitWand also ships .claude/commands/ for Claude Code:

/resolve   # Full conflict resolution workflow
/preview   # Merge preview and risk assessment

import { resolve } from "@gitwand/core";

const result = resolve(conflictedContent, "src/app.ts");
console.log(`${result.stats.autoResolved}/${result.stats.totalConflicts} resolved`);

// With options
const result = resolve(content, "package.json", {

Internationalization

GitWand uses a zero-dependency type-safe i18n system across five languages — English (en, default), French (fr), Spanish (es), Brazilian Portuguese (pt-BR), and Simplified Chinese (zh-CN). en.ts is the canonical reference, defined with as const; the Locale and LocaleKey types are derived from it, so every other locale must match its structure — TypeScript enforces it. The useI18n() composable provides t(key, ...args) with dotted key resolution and positional interpolation. OS language is auto-detected; users can override in Settings.
