Struct DynamicResourceTemplateRegistry 

pub struct DynamicResourceTemplateRegistry { /* private fields */ }

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

Obtained from McpRouter::with_dynamic_resource_templates(). Templates registered here are merged with the router’s static templates when handling resources/templates/list and resources/read requests. Static templates are checked before dynamic ones.

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

Example

use tower_mcp::{McpRouter, ResourceTemplateBuilder};

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

let template = ResourceTemplateBuilder::new("db://tables/{table}")
    .name("Database Table")
    .handler(|uri, vars| async move { /* ... */ });

registry.register(template);

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

List all currently registered dynamic resource templates.

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

Check if a template with the given URI pattern is registered.
