### Description (declared)

# lokryn-mcp-log

Compliance-grade audit logging for MCP (Model Context Protocol) client operations.

## What It Does

Wraps the official MCP Python SDK's `ClientSession` and logs every operation—tool calls, resource access, prompt executions—in a format that satisfies SOC2, HIPAA, and PCI audit requirements.

Logs conform to the lokryn-compliance-log-schema, an open standard for audit logging (schema vendored in this package, will be extracted to separate PyPI package).

## Installation

```bash
pip install lokryn-mcp-log
```

Or with uv:

```bash
uv add lokryn-mcp-log
```

## Quick Start

```python
from mcp import ClientSession, StdioServerParameters
from mcp.client.stdio import stdio_client
from lokryn_mcp_log import with_logging, StdoutSink

server_params = StdioServerParameters(command="python", args=["server.py"])

async def main():
    async with stdio_client(server_params) as (read, write):
        async with ClientSession(read, write) as session:
            await session.initialize()

            # Wrap with logging
            logged = with_logging(
                session,
                sink=StdoutSink(),
                environment="development",
            )

            # Use exactly like normal
            await logged.call_tool("add", {"a": 1, "b": 2})
```

## Sinks

### StdoutSink

```python
from lokryn_mcp_log import StdoutSink

sink = StdoutSink()           # JSON to stdout
sink = StdoutSink(pretty=True) # Pretty-printed
```

### FileSink

```python
from lokryn_mcp_log import FileSink

sink = FileSink("/var/log/mcp-audit.jsonl")
```

### HTTPSink

```python
import os
from lokryn_mcp_log import HTTPSink

# JSON format (default)
sink = HTTPSink(
    endpoint="https://your-log-collector.com/ingest",
    headers={"Authorization": "Bearer <token>"},
)

# Protobuf format
sink = HTTPSink(
    endpoint="https://your-log-collector.com/ingest/proto",
    format="protobuf",
)

# With HMAC signing
sink = HTTPSink(
    endpoint="https://your-log-collector…
