xcode_lldb

xcode_lldb is an MCP server for Claude Code from gaelic-ghost/socket. Its token cost is not measured, scanned A, original, Apache-2.0.

An MCP server that connects coding-agent tools to Xcode's LLDB debugger. LLDB is the debugger used to inspect and control running programs.

In plain words
What is it for?
Use it to register Xcode's LLDB MCP server through the `xcrun lldb-mcp` command when the installed Xcode version provides it.
Why use it?
It provides a bridge for experimental Xcode debugging workflows, while making clear that it depends on the installed Xcode toolchain and may need verification.

MCP server for Claude Code

Written for Claude Code: shipped in a Claude Code plugin. Also seen: listed in a Claude config.

Part of the apple-dev-skills plugin — 65 skills, 2 MCP servers shipped together

One of 2 entries in .mcp.json upstream. Installing this one merges just its entry into your config; the other 1 are separate, each on its own page.

Good fit Use it to register Xcode's LLDB MCP server through the xcrun lldb-mcp command when the installed Xcode version provides it.

Install with agentmods
npx agentmods add mcp/gaelic-ghost/socket/apple-dev-skills-xcode_lldb

Installing this writes the configuration, not the program: `xcrun` has to be on your PATH already, or the server will not start.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo
git clone --depth 1 https://github.com/gaelic-ghost/socket

Installing this writes the configuration, not the program: `xcrun` has to be on your PATH already, or the server will not start.

Made for: Claude Code.

Or install apple-dev-skills, the plugin that ships this one along with the rest of its 65 skills, 2 MCP servers.

Security

Grade A, and why

xcode_lldb scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
