# Agentstr - Nostr Agent Tools

## File Descriptions

### 1. `nwc_client.py`
A Python class (`NWCClient`) for interacting with a Nostr Wallet Connect (NWC) service to handle Lightning Network payments.

- **Functionality**:
  - Initialize with an NWC connection string.
  - List transactions (`list_tx`).
  - Get wallet balance (`get_balance`).
  - Create invoices (`make_invoice`).
  - Check invoice status (`check_invoice`).
  - Pay invoices (`try_pay_invoice`).
  - Monitor payment success with callbacks (`on_payment_success`).
- **Usage**: Used by other scripts to handle payment-related operations.
- **Example**: Create an invoice and monitor payment:
  ```python
  client = NWCClient(nwc_str)
  invoice = client.make_invoice(amt=5, desc='test')
  client.on_payment_success(invoice, callback=lambda: print('Payment succeeded'))
  ```

### 2. `nostr_client.py`
A core client (`NostrClient`) for interacting with the Nostr protocol.

- **Functionality**:
  - Initialize with relay URLs, private key, and optional NWC string.
  - Sign events with a private key.
  - Manage relay connections (`get_relay_manager`).
  - Read posts by tag (`read_posts_by_tag`).
  - Fetch and update user metadata (`get_metadata_for_pubkey`, `update_metadata`).
  - Send and listen for encrypted direct messages (`send_direct_message_to_pubkey`, `direct_message_listener`).
- **Usage**: Foundation for other scripts to interact with Nostr relays.
- **Example**: Read posts with a specific tag:
  ```python
  client = NostrClient(relays, private_key)
  posts = client.read_posts_by_tag('mcp_tool_discovery')
  ```

### 3. `nostr_mcp_client.py`
A client (`NostrMCPClient`) for interacting with MCP servers over Nostr.

- **Functionality**:
  - Initialize with a `NostrClient` and MCP server public key.
  - List available tools (`list_tools`).
  - Call tools with arguments, handling payments if required (`call_tool`).
- **Usage**: Used to invoke tools (e.g., math operations, weather queries) on remote MCP servers.
- **Example**: Call a multiplication tool:
  ```python
  mcp_client = NostrMCPClient(nostr_client, server_public_key)
  result = mcp_client.call_tool("multiply", {"a": 69, "b": 420})
  ```

### 4. `nostr_mcp_server.py`
A server (`NostrMCPServer`) that exposes tools via Nostr and handles tool execution with optional payment requirements.

- **Functionality**:
  - Initialize with a display name and `NostrClient`.
  - Add tools with optional pricing in satoshis (`add_tool`).
  - List available tools (`list_tools`).
  - Execute tools based on incoming requests (`call_tool`).
  - Handle direct messages to process tool calls and payments (`_direct_message_callback`).
  - Start the server to listen for requests (`start`).
- **Usage**: Hosts tools like math operations and responds to client requests.
- **Example**: Add and run a math server:
  ```python
  server = NostrMCPServer("Math MCP Server", client)
  server.add_tool(lambda a, b: a + b, name="add")
  server.start()
  ```

### 5. `nostr_agent_server.py`
A server (`NostrAgentServer`) that integrates an external agent API with Nostr for chat-based interactions.

- **Functionality**:
  - Initialize with an agent URL, satoshis cost, and `NostrClient`.
  - Fetch agent information (`agent_info`).
  - Handle chat requests with optional thread IDs (`chat`).
  - Process direct messages, requiring payments if specified (`_direct_message_callback`).
  - Start the server to listen for messages (`start`).
- **Usage**: Bridges Nostr with an external agent service.
- **Example**: Start an agent server:
  ```python
  server = NostrAgentServer(agent_url, 5, client)
  server.start()
  ```
