Struct AppStateProbes 

pub struct AppStateProbes { /* private fields */ }

Registry of application-defined state probes surfaced through the app_state MCP tool.

Probes give an agent first-class, discoverable access to domain state that would otherwise require query_db + log-grepping (e.g. a scoring pipeline’s version, queue depth, or cache stats). Because a probe runs in the Rust process with direct access to whatever state the app captured into it, it reads backend state with no IPC round-trip and no frontend involvement — the kind of introspection a browser-external tool like CDP cannot do.

Implementations

impl AppStateProbes

pub fn register(&self, name: impl Into<String>, probe: Arc<ProbeFn>)

Register (or replace) a probe under name.

pub fn names(&self) -> Vec<String>

Sorted list of registered probe names.

pub fn run(&self, name: &str) -> Option<Value>

Run the named probe and return its JSON snapshot, or None if no probe is registered under that name.

pub fn len(&self) -> usize

Number of registered probes.

pub fn is_empty(&self) -> bool

Returns true if no probes are registered.
