### Description (declared)

# scry

Marker-indexed SQL cache MCP server. Scry indexes in-file `@scry.*` markers
into a SQLite database that agents query via read-only SQL, providing
structured project knowledge without LLM reasoning.

## Install

```bash
uv pip install scry-mcp
# or:
pip install scry-mcp
```

The PyPI distribution is `scry-mcp` (the bare name `scry` was already taken
on PyPI). The import name and the installed console command are both
`scry`.

## Quickstart

```bash
# In your project root:
scry init                # scaffolds agent/ + driver dirs, updates .gitignore
```

Then add it to your MCP client config:

```json
{
  "mcpServers": {
    "scry": {
      "command": "scry"
    }
  }
}
```

The MCP client inherits cwd from wherever it's launched, and scry walks
up from there looking for an `agent/` directory — so the same config
works for any project. Bare `scry` (no subcommand) starts the MCP
server over stdio — that's what Claude calls. Other subcommands:

| Command | Purpose |
|---|---|
| `scry` | Run the MCP server (default). |
| `scry init [path]` | Create `agent/` + `agent/drivers/@local/scry/{data,runtime,scripts}/` and a local `.gitignore` inside the driver dir. Idempotent — safe to run inside an ACP project. |
| `scry surface [--force]` | One-shot batch reindex without booting the server. |
| `scry version` | Print the package version. |

The server walks up from `cwd` until it finds an `agent/` directory; that
becomes the project root. The cache lives at
`agent/drivers/@<namespace>/scry/data/project.db` and is gitignored.

## Markers

Scry recognizes three marker kinds per scry-spec v1.1: `@scry.entry` and
`@scry.anchor` are block markers with a YAML body between open/close tokens;
`@scry.bind` is a line or block marker declaring cross-references.
