### Description (declared)

# compresh-mcp

**MCP server for Compresh** — production-grade context compression for LLM agent conversations.

> Compresh adds **query-aware retrieval (TUL 2.0)** on top of the open-source
> [`tulbase`](https://github.com/compresh/tulbase) compression core. Instead of
> summarizing older turns, it retrieves the turns relevant to the current
> question — lossless and role-tagged — from the full conversation history.
> This is the **paid tier** distribution, and it works free without an account
> (local tulbase compression).

## Architecture (0.3.0+)

- **Local**: bundled `tulbase` (MIT, vendored as `compresh_mcp.tulbase`) runs on every turn for fast compression + cold-storage support (`fetch_compressed` / `list_compressed` MCP tools). Works with **no API key and no account** — fully local, free.
- **Server**: the **TUL 2.0** paid layer (query-aware retrieval over full history, role-preserving render) runs on Compresh infrastructure via the `/v1/tul2` endpoint, gated by your Compresh API key + tier.
- **Degraded mode**: if `/v1/tul2` is unreachable (or your trial/credit runs out), compresh-mcp transparently falls back to the local tulbase result so compression never blocks.

The paid endpoint was the legacy `/v1/tul1` through 0.2.x; 0.3.0 calls the
canonical `/v1/tul2` (the TUL 1.0 Q-matrix layer was retired in the 15 Jun
2026 retrieval pivot). The server keeps `/v1/tul1` as a deprecated alias, so
older clients keep working. Previously (0.1.0, yanked), paid classifiers
shipped inside the client package and leaked paid features locally — install
0.3.0 or later. See [CHANGELOG.md](./CHANGELOG.md).

## What's the difference vs `tulbase-mcp`?

Both ship the same open-source compression core (cleanup, TurnBox, modality
elision to cold storage, Protection Zone, LexRank summarization). `tulbase-mcp`
is currently GitHub-only (not yet on PyPI). The difference is what happens on
top of the shared core:

| Feature | `tulbase-mcp` (free, open-source) | `compresh-mcp` (paid) |
