### Description (declared)

# token-save-mcp

**Your coding agent burns its context reading files. This stops it — and shows you the receipt.**

Read one 4,000-line file and ~35,000 tokens sit in your agent's context for the
rest of the session. Read a few more and it compacts, forgets your
instructions, and every later turn costs more — because each one pays for the
whole accumulated context again.

This MCP server sends those files to a cheap worker model instead and returns
only the answer. The bytes are paid for once, in the worker's context, not
permanently in yours.

The hook **blocks** the expensive read and redirects it. The answer comes back
with the worker's **real token usage from the API response** — not an estimate,
a receipt:

```
─────────────────────────────────────────────────────────────
token-save: 1 file, 606 lines | direct read ≈7,042 tok →
into context ≈234 tok (saved 6,808 · 97%)
worker: glm-5.3-flash | 6,155 in / 278 out | 4.0s
```

*(`glm-5.3-flash` is just the worker configured in that run — you pick your own.)*

---

## Install

Two commands, plus an API key of your own.

```bash
pip install token-save-mcp
token-save-mcp init --hook
```

`init` finds a provider key you already have, registers the MCP server with
your agent, and installs the hook. If you have no key yet it prints the
options and where to get one.

One package, one command. There is no second MCP server to ad…
