AI Token Optimizer

An MCP server that cuts AI coding-agent token usage by 60–80% via framework-aware context optimization.

AI coding agents read whole files when they need 15 lines. They load *.g.dart, R.java, node_modules/, and dist/ into context — then do it again next turn. AI Token Optimizer is a Model Context Protocol server that intercepts those tool calls and strips framework noise before it reaches the model.

Works with anything that speaks MCP: Claude Code, Cursor, Cline, Continue, Zed, JetBrains AI, GitHub Copilot agent mode, Antigravity, Windsurf, OpenAI Codex CLI.

Quickstart

npm install -g @ai-optimizer/core

Then point your agent at the ai-optimizer stdio server. For Claude Code, add to ~/.claude/settings.json:

{
  "mcpServers": {
    "ai-optimizer": {
      "command": "ai-optimizer"
    }
  }
}

Or scaffold the config and preview your savings automatically:

npx @ai-optimizer/init
# "we'd skip 47 files, ~14K tokens/session, ~$0.42/session at Sonnet pricing"

Full per-agent setup (Cursor, others), LSP install, and verification steps live in packages/core/README.md.

What it does

It registers tools the agent uses instead of its built-in file/dir/error reads:

Tool	What it saves
optimized_read_file	Framework-aware skip + optional line slice
optimized_list_files	Walks the tree applying ignore globs (+ .gitignore)
optimized_grep	Content search scoped by ignore filters
optimized_diagnostics	Spawns the right LSP, returns errors + a narrow code window
read_symbol	LSP workspace/symbol slice instead of a full-file read (Pro/LSP)
strip_bash_noise	Strips ANSI, npm/maven/gradle progress, JVM warnings
optimizer_status	Detected frameworks, active packs, cumulative tokens saved

When a project type is detected (e.g. Python via pyproject.toml), the matching pack's ignore rules activate automatically. .gitignore is respected on top.

Tiers

	Free (MIT core)	Pro ($9/mo)	Team ($29/seat)
Framework packs	Python, JS/TS	+ React, Flutter, Java, Kotlin, Go, Rust, C#, Swift, Ruby, Elixir, PHP, Solidity	all Pro packs
History compaction	—	✓	✓
Scheduler (claude -p cron)	—	✓	+ work-stealing across providers
Audit log + secret redaction + policy	—	—	✓

See PRICING.md. Behavior-changing or data-sharing features (scheduler, work-stealing, telemetry) are off by default and require explicit opt-in. Display-only features (dollar-value savings) default on.
