Struct ToolProxy 

pub struct ToolProxy { /* private fields */ }

A tool-proxy that wraps multiple servers behind a single call_tool.

Implementations

impl ToolProxy

pub fn new( name: String, members: HashSet<String>, tool_dir: PathBuf, server_descriptions: &[(String, String)], ) -> Self

pub fn name(&self) -> &str

pub fn contains_server(&self, server_name: &str) -> bool

Whether server_name is a nested member of this proxy.

pub fn is_call_tool(&self, namespaced_tool_name: &str) -> bool

Whether a namespaced tool name refers to this proxy’s call_tool.

pub fn resolve_call(&self, arguments_json: &str) -> Result<ResolvedCall>

Parse and validate a proxy call_tool invocation.

pub fn instructions(&self) -> &str

pub fn tool_dir(&self) -> &Path

pub fn add_member(&mut self, server_name: String)

Register a new member server (e.g. after late OAuth registration).

pub fn dir(name: &str) -> Result<PathBuf, McpError>

Returns the directory for a tool-proxy’s tool definitions.

Uses $AETHER_HOME/tool-proxy/<name> or ~/.aether/tool-proxy/<name>.

pub async fn clean_dir(tool_dir: &Path) -> Result<(), McpError>

Clean up the tool directory for a proxy, removing all tool files.

pub fn call_tool_schema() -> Arc<Map<String, Value>>

Build the call_tool JSON schema used by the proxy’s virtual tool.

pub fn call_tool_definition(proxy_name: &str) -> ToolDefinition

Build a ToolDefinition for the proxy’s call_tool virtual tool.

pub async fn write_tools_to_dir( server_name: &str, client: &RunningService<RoleClient, McpClient>, tool_dir: &Path, ) -> Result<(), McpError>

Discover tools from a connected MCP server and write them as JSON files to tool_dir/<server_name>/.

pub fn extract_server_description( client: &RunningService<RoleClient, McpClient>, server_name: &str, ) -> String

Extract a one-line description for a nested server from its peer info.

Uses server_info.description, falling back to the server name.
