What is project-structure?

A guide to finding the right place for code in a repository containing seven servers. It helps distinguish server entry files from other modules and the correct location for new files or root scripts.

Use it to locate code, choose a directory for a new feature, and decide whether a change belongs in a server or at the repository root.

It reduces the risk of putting a tool, resource, prompt, transport, helper, or command-line option in the wrong part of the codebase.

How modelcontextprotocol/servers configures Claude Code

Reuse

Borrowing it

Nothing to install: this file belongs to modelcontextprotocol/servers. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

Copy the file

curl -O https://raw.githubusercontent.com/modelcontextprotocol/servers/main/.claude/skills/project-structure/SKILL.md

Clone the repo

git clone --depth 1 https://github.com/modelcontextprotocol/servers

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00077	$0.02079
Opus 5.5	$0.00031	$0.00832
Sonnet 5.5	$0.00015	$0.00416
Haiku 4.5	$0.00008	$0.00208

Security

Grade A, and why

project-structure 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 13d 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.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

project-structure is a skill published in the GitHub repository modelcontextprotocol/servers (91,815 stars, last pushed yesterday), with no licence file. It adds 77 tokens to every session and 2,079 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-12.
