Instructions

Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.

Tools

Functions exposed to the LLM to take actions

NameDescription
list_projectsA

List projects registered with the local MCP runner and their access mode.

project_infoA

Return project root, access mode, managed-worktree metadata, and Git branch state.

list_directoryA

List one directory inside a registered project while hiding sensitive paths.

find_filesA

Recursively find files/directories by name substring without traversing sensitive paths, symlinks, or dependency/build directories.

search_textA

Search for a fixed text string in project files with bounded output; regex and shell execution are not used.

read_fileA

Read one UTF-8 text file inside a registered project.

read_filesA

Read up to 20 UTF-8 text files from one registered project.

file_infoA

Return size and SHA-256 for an existing text file.

create_directoryA

Create a directory path only in a write-enabled non-protected project/worktree; symlink traversal is blocked.

create_fileA

Create a new UTF-8 file in a write-enabled project. Existing files are never overwritten.

replace_textA

Replace exactly one text block in an existing file using an expected SHA-256 concurrency guard.

delete_fileA

Delete one existing file only when the caller supplies its exact current SHA-256.

git_statusC

Return safe Git status while omitting sensitive-path entries.

git_diffA

Return a bounded diff excluding sensitive files. Supports working-tree, staged, or ref-to-ref diffs.

git_logB

Return recent commit metadata, optionally scoped to one safe path.

git_branch_listB

List local Git branches and the current branch.

git_create_branchA

Create an mcp/* branch without checking it out. main/master and arbitrary branch names are not permitted.

git_worktree_createB

Create/register an isolated writable worktree on an mcp/* branch under the runner worktree directory.

git_worktree_removeA

Remove a clean runner-managed worktree and unregister it. Dirty worktrees are refused; the branch is retained.

git_commitA

Stage and commit only non-sensitive changes in a writable runner-managed mcp/* worktree. Hooks and GPG signing are disabled; push is not available.

project_scriptsA

List package.json scripts and report whether sandboxed execution is supported for this project. executionSupported answers 'can this environment run scripts at all'; executionEnabled folds in the kill switch.

run_scriptA

Execute an allowlisted, hash-pinned npm/pnpm script inside a macOS Seatbelt sandbox. network is always 'none'; script execution is confined to a runner-managed READ_WRITE mcp/* worktree. A non-zero script exit code is a successful MCP call (the script ran; the test failed).

github_repository_infoA

Query metadata for a GitHub repository under an allowlisted organization. Returns existence, owner, visibility, default branch, fork/archived flags, and repository URL.

github_repository_createA

Create a new repository under an allowlisted GitHub organization with specified visibility (public or private). Idempotent: returns ALREADY_EXISTS if repository already exists with matching visibility. Does NOT initialize with README/license/gitignore, does NOT push code, does NOT configure remotes.

A3.5/5.0

Scored across 24 tools

Disambiguation5/5

Every tool targets a distinct resource and action: project listing vs project detail, single-file vs multi-file reads, name-based search vs content search, and Git operations are all cleanly separated. Even similar-sounding tools like git_create_branch and git_worktree_create are clearly differentiated by their descriptions.

Naming Consistency3/5

All names are readable lowercase snake_case with useful domain prefixes, but conventions are mixed: list_projects is verb-first while project_info is noun-first, create_file is verb-first while github_repository_create is object-first, and git_branch_list places list at the end. The patterns are understandable but not consistent enough for a 4 or 5.

Tool Count3/5

With 24 tools, this sits in the heavy 16-25 band. The broad multi-domain scope justifies much of the surface area, but several tools could plausibly be consolidated, and the overall selection size is larger than the typical well-scoped MCP server.

Completeness4/5

The core lifecycle is well covered: project discovery, file exploration/reading, bounded file mutations, Git branch/worktree/commit workflows, and script execution all have sensible tooling. Minor gaps exist, such as no push/merge/rename operations, but these appear intentional given the sandboxed, runner-focused design.
