Struct BearerAuthContext 

pub struct BearerAuthContext {
    pub client_addr: SocketAddr,
    pub route: String,
    pub action: String,
    pub payload: Option<Value>,
}

Per-request context passed to a dynamic bearer-token authorizer.

The MCP runtime builds this value before dispatching a request to the protocol implementation. Servers can inspect it to make authorization decisions that depend on more than the raw token string.

Payload shape

payload is deliberately transport-shaped:

• streamable HTTP JSON-RPC requests receive the params object, such as { "name": "tool_name", "arguments": { ... } } for tools/call.
• legacy /tools/execute requests receive the full request body, usually { "tool": "tool_name", "parameters": { ... } }.
• metadata-style routes such as /tools/list and /resources/list receive None when there is no useful body to authorize.

Server crates keep ownership of policy. For example, a memory server can inspect tool arguments inside payload and allow a token for one chain while denying the same token for another.

Fields

client_addr: SocketAddr

Client socket address reported by the HTTP framework.

route: String

HTTP route that received the request.

action: String

MCP method or legacy action being authorized.

payload: Option<Value>

Parsed request payload or JSON-RPC params, when available.

This value is cloned from the already-parsed request body so authorizers do not need to parse JSON a second time.

Trait Implementations

impl Clone for BearerAuthContext

fn clone(&self) -> BearerAuthContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BearerAuthContext

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for BearerAuthContext

fn eq(&self, other: &BearerAuthContext) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
