everything-mcp: Instructions file for Claude Code

AGENTS.md

everything-mcp AGENTS.md is an instructions file for Claude Code, Codex, OpenCode from danielsimonjr/everything-mcp. It costs 1,000 tokens per session, scanned A, original, MIT.

A repository guide for AI agents working on everything-mcp, a Windows server that searches files through Everything, a desktop file-search tool. It explains the source and built bundle that must stay synchronized.

In plain words
What is it for?
Use it when changing the search or file-information tools, updating the bundle or checking how the server is launched.
Why use it?
It prevents fixes from being made only in the source while the running configuration still uses an unchanged bundle or separate copy.

Instructions file for Claude CodeCodexOpenCode

Written for Claude Code and Codex and OpenCode: ${CLAUDE_PLUGIN_ROOT} variable, but also the file is AGENTS.md. Also seen: mentions Claude Code; mentions AGENTS.md.

This is danielsimonjr/everything-mcp's own configuration. It tells Claude Code, Codex and OpenCode how to work on everything-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything everything-mcp configures →

Runs only inside a plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else, and the catalogue could not identify which plugin ships it.

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.

Security

Grade A, and why

everything-mcp AGENTS.md 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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — everything-mcp

How to operate on this repo without breaking it. Read this and MEMORY.md before making changes. Pairs with TODO.md (open work).

What this is

MCP server (@danielsimonjr/everything-mcp, Windows-only, CommonJS) that wraps es.exe — the command-line client for Everything — and exposes two tools: search and get_file_info. Depends on @modelcontextprotocol/sdk.

The five things that bite

  1. Two copies of the code — edit both, or the fix is cosmetic.

    • index.js — the source (CommonJS, package.json main).
    • bundle/index.mjs — the built ESM bundle that .mcp.json actually launches (${CLAUDE_PLUGIN_ROOT}/bundle/index.mjs).
    • There is no build script (package.json scripts is {}) and no esbuild in node_modules. So the bundle is not regenerated — you must hand-port any index.js change into bundle/index.mjs and keep them in sync. The bundle has a __require shim, so __require("fs") / __require("path") work inside it.

  2. The running server is NOT this repo (on the maintainer's machine). Claude Code loads a separate copy at %USERPROFILE%\servers\src\everything-mcp\index.js via .claude.json. Changes here do not affect the running MCP until they are redeployed to servers\src (or .claude.json is repointed). See TODO.md.

  3. CRLF churn — normalize to LF before staging. No .gitattributes + core.autocrlf=false. Any editor that saves CRLF flips the entire file to "modified" (every line -/+, equal insert/delete counts). If you git add such a file you commit thousands of noise lines that bury the real change. Before staging an edited file:

    tr -d '\r' < index.js > index.js.tmp && mv -f index.js.tmp index.js
git diff HEAD --stat -- index.js   # should be tiny

    Confirm a suspected EOL flip with: git diff HEAD --ignore-all-space -- <file> (empty = pure EOL, no real change).

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.
