### Claude Desktop MCP Configuration
@ -33,24 +35,68 @@ Add the following to your Claude Desktop MCP configuration file:
```json
{
"tools": [
{
"name": "mcpssh",
"path": "python -m mcpssh",
"environment": {
"mcpssh": {
"command": "python",
"args": [
"-m",
"mcpssh"
],
"env": {
"MCP_SSH_HOSTNAME": "example.com",
"MCP_SSH_PORT": "22",
"MCP_SSH_USERNAME": "user",
"MCP_SSH_KEY_FILENAME": "/path/to/private_key"
}
}
]
}
```
### Multiple SSH Server Configuration
You can configure multiple SSH servers in Claude Desktop by creating multiple entries with different names and using the `MCP_SSH_SERVER_NAME` and `MCP_SSH_TOOL_PREFIX` environment variables to distinguish them:
```json
{
"mcpssh1": {
"command": "python",
"args": [
"-m",
"mcpssh"
],
"env": {
"MCP_SSH_HOSTNAME": "production.example.com",
"MCP_SSH_USERNAME": "prod-user",
"MCP_SSH_KEY_FILENAME": "~/.ssh/prod_key",
"MCP_SSH_SERVER_NAME": "Production Server",
"MCP_SSH_TOOL_PREFIX": "prod_"
}
},
"mcpssh2": {
"command": "python",
"args": [
"-m",
"mcpssh"
],
"env": {
"MCP_SSH_HOSTNAME": "dev.example.com",
"MCP_SSH_USERNAME": "dev-user",
"MCP_SSH_KEY_FILENAME": "~/.ssh/dev_key",
"MCP_SSH_SERVER_NAME": "Development Server",
"MCP_SSH_TOOL_PREFIX": "dev_"
}
}
}
```
With this configuration:
1. Claude will have access to two separate SSH server tools
2. Each server will be identified by its custom name in Claude's UI
3. Each server's tools will have unique prefixes to distinguish them (e.g., `prod_ssh_connect` vs `dev_ssh_connect`)
## Usage
This server implements the Anthropic MCP protocol and provides the following tools:
This server implements the Anthropic MCP protocol and provides the following tools (note that when using `MCP_SSH_TOOL_PREFIX`, the tool names will be prefixed with that value):
- `ssh_connect`: Connect to an SSH server using public key authentication (using config or explicit parameters)
- `ssh_execute`: Execute a command on the SSH server
