mcp-standardized git tool exposure via schema-based function registry
Exposes 25+ Git operations as MCP tools through a standardized three-file architecture (logic, handler, schema) that implements the 'Logic Throws, Handler Catches' pattern. Each tool is registered with Zod-validated input schemas and structured output types, enabling AI agents to discover and invoke Git operations with type safety. The MCP SDK (@modelcontextprotocol/sdk ^1.17.0) handles protocol negotiation and tool marshaling across both STDIO and HTTP transports.
Unique: Uses a consistent three-file architecture pattern (logic/handler/schema) across all 25+ Git tools, enabling predictable tool registration and reducing boilerplate. Implements 'Logic Throws, Handler Catches' principle where business logic throws domain errors and MCP handlers translate them to protocol-compliant responses.
vs alternatives: More standardized and discoverable than custom REST APIs or direct CLI wrapping because it leverages MCP's native tool schema negotiation, allowing any MCP-compatible client to auto-discover Git capabilities without client-side configuration.
dual-transport mcp server with stdio and http backends
Implements both STDIO (process-level IPC) and HTTP (Hono-based web server) transports for MCP communication, selectable via MCP_TRANSPORT_TYPE environment variable. STDIO transport launches as a child process with direct stdin/stdout communication for tight client-server coupling; HTTP transport runs a Hono web server on port 3010 (with automatic retry) supporting CORS, JWT/OAuth authentication via JOSE, and session persistence. Both transports route to the same underlying MCP server logic, enabling flexible deployment patterns.
Unique: Provides true dual-transport support with a single codebase by abstracting transport concerns from business logic. HTTP transport includes JWT/OAuth authentication via JOSE and session management, while STDIO transport leverages OS-level process isolation for security.
vs alternatives: More flexible than single-transport MCP servers because it supports both tight local integration (STDIO) and distributed deployment (HTTP) without code duplication, and includes authentication for HTTP unlike basic MCP server implementations.
pull operations with merge/rebase strategy selection
Implements git pull with configurable merge strategies (merge, rebase, fast-forward only) and automatic conflict detection. Uses git pull with strategy flags (--rebase, --ff-only, --no-ff) and captures merge/rebase output including conflict information. Detects merge conflicts and returns structured response indicating conflict status and affected files. Supports pulling from specific remotes and branches.
Unique: Provides configurable merge strategies (merge, rebase, ff-only) as tool parameters rather than requiring separate tool calls, and detects/reports merge conflicts in structured format enabling downstream conflict resolution logic.
vs alternatives: More flexible than basic git pull because it supports multiple merge strategies and detects conflicts with structured reporting, enabling LLMs to choose appropriate strategy and handle conflicts programmatically rather than failing on conflict.
merge operations with conflict detection and resolution tracking
Implements git merge with support for merging branches into current branch, detecting conflicts, and optionally aborting on conflict. Uses git merge with configurable flags (--no-commit for dry-run, --abort for rollback) and parses merge output to identify conflicted files and merge status. Returns structured merge result including conflict information and affected files. Supports both fast-forward and non-fast-forward merges.
Unique: Detects and reports merge conflicts in structured format with affected file list, and supports --no-commit for dry-run merges, enabling LLMs to preview merges and handle conflicts programmatically rather than failing on conflict.
vs alternatives: More robust than basic git merge because it detects conflicts before committing and supports dry-run mode, enabling LLMs to understand merge implications and make decisions about conflict resolution strategy.
rebase operations with interactive mode and conflict handling
Implements git rebase with support for rebasing onto different branches or commits, interactive rebase for commit editing, and conflict detection. Uses git rebase with configurable flags (--interactive for interactive mode, --abort for rollback, --continue for resuming after conflict resolution). Detects rebase conflicts and returns structured response indicating conflict status and affected commits. Supports rebasing current branch or specific branches.
Unique: Supports interactive rebase mode for commit editing and provides conflict detection with structured reporting, enabling LLMs to understand rebase implications and handle conflicts programmatically.
vs alternatives: More powerful than basic git rebase because it supports interactive mode for commit editing and detects conflicts with structured reporting, enabling LLMs to clean up history and handle conflicts rather than failing on conflict.
tag creation and management with annotation support
Implements git tag operations for creating lightweight and annotated tags, listing tags with filtering, and deleting tags. Supports creating tags at specific commits or HEAD, annotated tags with messages and tagger information, and listing tags with optional filtering by pattern. Uses git tag with configurable flags (-a for annotated, -d for deletion) and returns structured tag information including tag name, type, and target commit.
Unique: Supports both lightweight and annotated tags with optional messages, and provides structured tag information in responses, enabling LLMs to create semantic version tags and track release history.
vs alternatives: More complete than basic git tag because it supports annotated tags with messages and provides structured tag information, enabling LLMs to create meaningful release tags and query release history.
worktree management for parallel branch development
Implements git worktree operations for creating isolated working directories for different branches, listing active worktrees, and removing worktrees. Uses git worktree add/list/remove commands to manage multiple working directories pointing to different branches of the same repository. Each worktree has its own working directory but shares the .git directory, enabling parallel development on multiple branches without switching. Returns structured worktree information including path, branch, and lock status.
Unique: Provides worktree management enabling parallel development on multiple branches without switching, with structured worktree information in responses, enabling LLMs to coordinate work across multiple branches simultaneously.
vs alternatives: More powerful than branch switching because worktrees enable true parallel development without context switching, allowing LLMs to work on multiple branches concurrently and coordinate changes across branches.
stash operations for temporary change storage and retrieval
Implements git stash operations for saving uncommitted changes, listing stashed changes, applying stashes, and deleting stashes. Uses git stash with configurable flags (save/push for stashing, apply/pop for retrieving, drop for deletion) and supports stashing specific files. Returns structured stash information including stash ID, description, and affected files. Enables temporary storage of work-in-progress changes without committing.
Unique: Provides stash management with structured stash information and support for selective stashing, enabling LLMs to temporarily save changes and manage multiple stashes without committing.
vs alternatives: More useful than raw git stash because it provides structured stash information and supports selective stashing, enabling LLMs to manage work-in-progress changes and coordinate stash operations across multiple steps.
