Struct ToolRegistry 

pub struct ToolRegistry { /* private fields */ }

Implementations

impl ToolRegistry

pub fn new() -> Self

pub async fn register(&self, tool: Box<dyn Tool>)

Register a tool (async, acquires write lock).

pub fn register_sync(&mut self, tool: Box<dyn Tool>)

Register a tool synchronously (for use during startup when we have exclusive access). This bypasses the RwLock by using get_mut() which requires &mut self.

pub async fn get_definitions(&self) -> Vec<ToolDef>

Get all tool definitions (async, acquires read lock).

pub async fn get(&self, name: &str) -> Option<Arc<dyn Tool>>

Get a tool by name (async, acquires read lock).

pub async fn iter(&self) -> impl Iterator<Item = (String, Arc<dyn Tool>)>

Iterate over all registered tools (async, acquires read lock).

pub async fn register_arc(&self, name: String, tool: Arc<dyn Tool>)

Register a tool from an Arc (for building filtered registries from parent).

pub async fn expected_top_keys(&self, name: &str) -> Vec<String>

Top-level property names declared in the tool’s parameters schema. Used by recover_tool_args to decide whether a payload needs wrapper unwrapping. Returns empty Vec if the tool isn’t registered or the schema doesn’t expose properties (in which case recover_tool_args falls back to its permissive branch).

pub async fn unregister_prefix(&self, prefix: &str) -> usize

Unregister all tools whose names start with prefix.

Used by /mcp reload to drop all previously registered MCP tools (mcp__{server}__{tool}) before reconnecting/re-registering.
