# humanus.cpp

Humanus (meaning "human" in Latin) is a lightweight framework inspired by [OpenManus](https://github.com/mannaandpoem/OpenManus) and [mem0](https://github.com/mem0ai/mem0), integrated with the Model Context Protocol (MCP). `humanus.cpp` enables more flexible tool choices, and provides a foundation for building powerful local LLM agents.

Let's embrace local LLM agents **w/** humanus.cpp!

## Project Demo

## How to Build

```bash
git submodule update --init --recursive

cmake -B build
cmake --build build --config Release
```

## How to Run

### Configuration

Switch to your own configration first:
1. Copy configuration files from `config/example` to `config`.
2. Replace `base_url`, `api_key`, .etc in `config/config_llm.toml` and other configurations in `config/config*.toml` according to your need.
    > Note: `llama-server` in [llama.cpp](https://github.com/ggml-org/llama.cpp) also support embedding models.
3. Fill in `args` after `"@modelcontextprotocol/server-filesystem"` for `filesystem` to control the access to files. For example:
```
[filesystem]
type = "stdio"
command = "npx"
args = ["-y",
        "@modelcontextprotocol/server-filesystem",
        "/Users/{Username}/Desktop",
        "other/path/to/your/files]
```

### `mcp_server`

(for tools, only `python_execute` as an example now)

Start a MCP server with tool `python_execute` on port 8895 (or pass the port as an argument):
```bash
./build/bin/mcp_server <port> # Unix/MacOS
```

```shell
.\build\bin\Release\mcp_server.exe  <port> # Windows
```

### `humanus_cli`

Run with tools `python_execute`, `filesystem` and `playwright` (for browser use):

```bash
./build/bin/humanus_cli # Unix/MacOS
```

```shell
.\build\bin\Release\humanus_cli.exe # Windows
```

### `humanus_cli_plan` (WIP)

Run planning flow (only agent `humanus` as executor):
```bash
./build/bin/humanus_cli_plan # Unix/MacOS
```

```shell
.\build\bin\Release\humanus_cli_plan.exe # Windows
```

### `humanus_server` (WIP)

Run agents in MCP the server (default running on port 8896):
- `humanus_initialze`: Pass JSON configuration (like in `config/config.toml`) to initialize an agent for a session. (Only one agent will be maintained for each session/client)
- `humanus_run`: Pass `prompt` to tell the agent what to do. (Only one task at a time)
- `humanus_terminate`: Stop the current task.
- `humanus_status`: Get the current states and other information about the agent and the task. Returns:
  - `state`: Agent state.
  - `current_step`: Current step index of the agent.
  - `max_steps`: Maximum steps executing without interaction with the user.
  - `prompt_tokens`: Prompt (input) tokens consumption.
  - `completion_tokens`: Completion (output) tokens consumption.
  - `log_buffer`: Logs in the buffer, like `humanus_cli`. Will be cleared after fetched.
  - `result`: Explaining what the agent did. Not empty if the task is finished.

```bash
./build/bin/humanus_server <port> # Unix/MacOS
```

```shell
.\build\bin\Release\humanus_cli_plan.exe <port> # Windows
```

Configure it in Cursor:
```json
{
  "mcpServers": {
    "humanus": {
      "url": "http://localhost:8896/sse"
    }
  }
}
```

> What if add `humanus` to `mcp_servers`? It might be interesting.
