How do I use token-saver-mcp?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@token-saver-mcp Use smart_read_file on models/user.js for 'findByEmail'" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

token-saver-mcp

An MCP server plugin for Claude Code that automatically reduces token usage across your sessions. All optimizations are purely algorithmic — no extra API calls, no added cost.

Tools

Tool	What it does
`compress_text`	Strips comments (`//`, `/* */`, `#`, `<!-- -->`), blank lines & whitespace from code/prose. String-aware: never corrupts URLs, `#hashtag`/`#fff` hex colors, or markers inside string literals; comments inside template-literal `${}` expressions are stripped
`smart_read_file`	Reads only relevant sections of a file. Structure-aware across JS/TS, Python, Go, Rust, Java & C#: returns the complete enclosing function/class/interface around keyword matches, with a configurable fallback window. Rejects binary files
`summarize_output`	Truncates long command output / logs to a token budget. Preserves error/failure lines anywhere in the output, keeps head + tail, collapses duplicate lines
`summarize_diff`	Compacts a unified git diff: keeps file headers, hunk headers & changed lines; strips context lines and index/mode noise. Renames and binary files are annotated
`count_tokens`	Counts token usage for any text (cl100k_base encoding)
`generate_claudeignore`	Generates a `.claudeignore` covering Node, Python, Rust, Go, Java, Ruby, PHP & Terraform artifacts plus modern tooling caches (Turbo, Vercel, Nuxt, SvelteKit, Storybook), seeded from your existing `.gitignore`
`optimize_prompt`	Rewrites verbose prompts to be concise (~40 filler-phrase rules). Fenced code blocks and inline code are passed through untouched

All tools return plain text with a compact stats footer — results are deliberately not JSON-wrapped, since JSON escaping of newlines and quotes would inflate the very token count this server exists to reduce.

Note on token counts: the server uses the cl100k_base encoding (via tiktoken), which is OpenAI's tokenizer. Claude's tokenizer differs, so all counts are approximations — typically within ~10–20% of Claude's actual usage. Relative savings percentages are unaffected.

Benchmark results

Measured against real code fixtures and realistic prompt inputs. See benchmark/BENCHMARK.md for full methodology.

Tool	Avg token reduction	Best case
`compress_text`	31%	53% on JS with JSDoc
`smart_read_file`	44%*	81% extracting one function from a module
`summarize_output`	76%	84% on long build output
`summarize_diff`	50%	53% on a multi-file diff with renames
`optimize_prompt`	28%	52% on heavily padded prompts
`count_tokens`	accuracy tool — no reduction metric	—
`generate_claudeignore`	structural correctness tool — no reduction metric	—

* the smart_read_file average includes tiny synthetic fixtures used as multi-language correctness tests; on realistic files it ranges 38–81%.

Run the benchmark yourself:

npm run benchmark

Installation

1. Clone and install

git clone <your-repo-url> token-saver-mcp
cd token-saver-mcp
npm install

2. Add to Claude Code

claude mcp add token-saver -- node /absolute/path/to/token-saver-mcp/src/index.js

Or manually edit ~/.claude.json under mcpServers:

{
  "mcpServers": {
    "token-saver": {
      "command": "node",
      "args": ["/absolute/path/to/token-saver-mcp/src/index.js"]
    }
  }
}

3. Verify

claude mcp list

You should see token-saver listed as connected.

Usage examples

Use smart_read_file on src/api/routes.js, focus on "authentication" and "middleware"

Generate a .claudeignore for my project at /home/user/myapp and write it to disk
