### Description (declared)

# Cragkit MCP host for Python

Expose application-owned Cragkit retrieval through a local stdio MCP host.
The host provides the `cragkit_retrieve` tool and returns validated evidence,
coverage estimates, limitations and diagnostics. Your application controls
identity, store access, model clients and the final answer.

This is an optional transport package. It is not a hosted retrieval service or a
general-purpose database administration server.

This release restores PyPI publication attestations and retains the package
description. Runtime behavior is unchanged from RC2. See the [RC3 release notes](https://github.com/vsuman00/Cragkit/blob/main/docs/releases/RC3.md).

## Install

Requires Python `>=3.14,<3.15`. This release candidate installs matching Cragkit
core and the pinned MCP SDK dependency.

```sh
python -m pip install "cragkit-mcp==1.0.0rc3"
```

The package exports `create_server` and `RetrievalHost`. It does not supply a
configured engine or automatically start a background server.

## Try the host without starting stdio

This complete example constructs a host and calls its local retrieval method.
The synthetic engine always returns no evidence; no database, model or MCP
client is required. It is a wrapper demonstration, not backend verification.

```python
import asyncio
import json

from cragkit.contracts import parse_scope
from cragkit_mcp import create_server

class ExampleEngine:
    async def retrieve(self, request, *, scope, deadline):
        return {"result": {
            "request_id": request.request_id,
            "status": "insufficient",
            "execution": "complete",
            "evidence": [],
            "facets": [],
            "context": "",
            "limitations": [{"code": "coverage_unknown"}],
        }}

async def main():
    scope = parse_scope({
        "tenant_id": "example-tenant",
        "principal_id": "example-user",
        "authorization_revision": "r1",
        "grant_ids": ["engineering-read"],
    })
