### Description (declared)

# slife-mcp

Standalone MCP proxy service — manages persistent connections to external MCP servers and exposes them through a single MCP endpoint.

## Quick Start

```bash
pip install slife-mcp

# Run — auto-detects mode:
slife-mcp                      # with slife.json5 → HTTP, without → stdio
slife-mcp --port 8888          # HTTP on custom port
slife-mcp --host 0.0.0.0 --port 9876  # HTTP on all interfaces
```

## How It Works

```
MCP clients ←→ slife-mcp ←→ external MCP servers (filesystem, search, fetch, …)
```

slife-mcp acts as a **proxy layer** between MCP clients and external MCP servers. Instead of each client managing its own server connections, slife-mcp maintains persistent connections centrally and exposes all tools through a single endpoint.

Key design decisions:

- **Raw JSON-RPC over subprocess pipes** — no `anyio`, no `ClientSession`. Avoids `TaskGroup` conflicts with FastMCP and keeps the implementation simple and debuggable.
- **Connection pooling** — servers are kept alive across requests. Disconnected servers can be reconnected at runtime without restarting slife-mcp.
- **Stderr capture** — when a server fails to connect, its stderr output is included in the error message so the LLM (or human operator) can understand and fix the problem.
- **Progressive disclosure** — servers default to eager mode (tools loaded at startup), but can be configured as lazy (connected, tools hidden) to keep the tool list lean. Switch between modes at runtime with `mcp_set_disclosure`.

This supports any MCP-compatible server, including:

- **Pre-built MCP servers** — filesystem, web search (Serper, Tavily), fetch, etc.
- **REST API servers** — [anyapi-mcp-server](https://github.com/quiloos39/anyapi-mcp-server) converts OpenAPI specs to MCP tools, making any REST API (GitHub, Jira, GitLab, Slack…) callable as tools.

## Configuration

Create `slife.json5` in your working directory:

```json5
{
  mcp: {
    // wrapper.url — where clients connect to slife-mcp
