jarvis-mcp-server: Instructions file for Claude Code

CLAUDE.md

jarvis-mcp-server CLAUDE.md is an instructions file for Claude Code from Gallucky/jarvis-mcp-server. It costs 1,629 tokens per session, scanned A, original, MIT.

Project instructions for Jarvis MCP Server, a personal server that combines a TypeScript web service, a SQLite database, an Obsidian notes connection, and dashboard pages. They describe its folders, tools, database migrations, and conventions.

In plain words
What is it for?
Use them when extending server tools, schemas, database tables, migrations, Obsidian syncing, or the home and study dashboards. They also identify the main build and data components.
Why use it?
They give coding agents the project map and rules for adding tools, database tables, dashboard features, and migrations consistently. This reduces guesswork about where changes belong.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md.

This is Gallucky/jarvis-mcp-server's own configuration. It tells Claude Code how to work on jarvis-mcp-server 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 jarvis-mcp-server configures →

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

jarvis-mcp-server CLAUDE.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 8d 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.

jarvis-mcp-server

Personal MCP server running on a home mini PC, exposed via Tailscale. Built with TypeScript + Express + better-sqlite3.

Stack

  • src/index.ts — Express server, OAuth 2.1, MCP transport
  • src/tools/ — one file per domain: vault.ts, sqlite.ts, filesystem.ts, jarvis.ts, study/psychometric.ts
  • src/services/db.ts — single better-sqlite3 connection to data/jarvis.db
  • src/services/obsidianClient.ts — wraps Obsidian Local REST API
  • src/routes/dashboard.ts/dashboard (home hub HTML shell), /dashboard/study (study HTML shell) + /api/stats (JSON)
  • src/dashboard/ — React UI source: home/ (OS hub), study/ (study tracker), shared/ (RingChart, shared.css) — two esbuild entry points bundled into public/home.{js,css} and public/study.{js,css}
  • src/scripts/syncCheckboxes.ts — parses vault homework markdown → SQLite
  • src/scripts/migrate.ts — applies SQL files from migrations/
  • migrations/ — numbered .sql files (currently: 001_exercise_completions.sql)

Key conventions

  • New tool domain → new file in src/tools/, matching schema in src/schemas/, register in buildServer() in index.ts
  • New DB table → new file in migrations/, run npm run migrate
  • Path safety: all fs_* tools run through src/utils/pathSafety.ts (allowlist in src/constants.ts)
  • Dashboard is two real React apps under src/dashboard/{home,study}/, sharing src/dashboard/shared/ (RingChart component, shared.css with fonts/reset/card/ring rules via @import). Bundled locally with esbuild (two named entry points, home=... and study=...) — no CDN dependency, works with no outbound internet access. src/routes/dashboard.ts only serves HTML shells + JSON API; src/dashboard/ is excluded from the main tsc build (tsconfig.json excludes it; that folder has its own tsconfig.json for editor JSX/DOM support)
  • /dashboard is the OS-level hub: a grid of blocks (home/components/HomeBlock.tsx). Each block is either a live link (href set, e.g. the study tracker with its progress ring) or an unlinked "בקרוב" (coming soon) placeholder for future tools (home/components/Home.tsx's IDEA_BLOCKS array) — turning a placeholder into a real feature is just adding href/pct to its entry
  • Dashboard font is self-hosted Rubik (public/fonts/Rubik-{hebrew,latin}.woff2, committed to the repo — not a build artifact; only home.{js,css}/study.{js,css} are gitignored). shared.css holds the @font-face rules; esbuild's --external:/fonts/* keeps those url() paths root-relative instead of trying to resolve them on disk
  • The study page's "לפי שיעור" lesson tiles link to obsidian://open?vault=...&file=... using the hardcoded VAULT_NAME in study/components/Study.tsx — update it if the vault is ever renamed

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.
