Struct DynamicResourceRegistry 

pub struct DynamicResourceRegistry { /* private fields */ }

A thread-safe, cloneable handle for runtime resource management.

Obtained from McpRouter::with_dynamic_resources(). Resources registered here are merged with the router’s static resources when handling resources/list and resources/read requests. Static resources take precedence over dynamic resources when URIs collide.

When a resource is registered or unregistered, all connected sessions receive a notifications/resources/list_changed notification.

Example

use tower_mcp::{McpRouter, ResourceBuilder};

let (router, registry) = McpRouter::new()
    .server_info("my-server", "1.0.0")
    .with_dynamic_resources();

let resource = ResourceBuilder::new("file:///data.json")
    .name("Data")
    .text(r#"{"key": "value"}"#);

registry.register(resource);

Implementations

impl DynamicResourceRegistry

pub fn register(&self, resource: Resource)

Register a resource, replacing any existing resource with the same URI.

Broadcasts ResourcesListChanged to all connected sessions.

pub fn unregister(&self, uri: &str) -> bool

Unregister a resource by URI.

Returns true if the resource existed and was removed. Broadcasts ResourcesListChanged only if the resource was actually removed.

pub fn list(&self) -> Vec<Arc<Resource>>

List all currently registered dynamic resources.

pub fn contains(&self, uri: &str) -> bool

Check if a resource with the given URI is registered.

Trait Implementations

impl Clone for DynamicResourceRegistry

fn clone(&self) -> DynamicResourceRegistry

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
