Enum McpServerEntry 

pub enum McpServerEntry {
    Simple(String),
    Full {
        url: String,
        auth_header: Option<String>,
        resource: Option<String>,
        scopes: Option<Vec<String>>,
    },
    Stdio {
        command: String,
        args: Vec<String>,
        env: HashMap<String, String>,
    },
}

An MCP server entry: a bare URL string, a full HTTP config with auth, or a stdio command to spawn as a child process.

Supports backward-compatible TOML: bare strings ("http://...") deserialize as Simple, inline tables with url ({ url = "...", auth_header = "..." }) as Full, and inline tables with command ({ command = "npx", args = [...] }) as Stdio.

Variants

Simple(String)

Bare URL string (backward-compatible).

Full

Full HTTP entry with optional auth header.

Fields

url: String

auth_header: Option<String>

resource: Option<String>

RFC 8707 resource indicator — audience for exchanged tokens. Defaults to the url value when absent.

scopes: Option<Vec<String>>

OAuth scopes required by this MCP server (e.g., ["gmail.readonly"]).

Stdio

Stdio transport — spawn a child process communicating via stdin/stdout.

Fields

command: String

args: Vec<String>

env: HashMap<String, String>

Implementations

impl McpServerEntry

pub fn url(&self) -> &str

Get the server URL (empty string for stdio entries).

pub fn auth_header(&self) -> Option<&str>

Get the optional auth header value.

pub fn is_stdio(&self) -> bool

Whether this entry uses stdio transport.

pub fn resource(&self) -> Option<&str>

Get the RFC 8707 resource indicator (audience for token exchange). Returns the explicit resource if set, otherwise falls back to the URL.

pub fn scopes(&self) -> Option<&[String]>

Get the OAuth scopes configured for this MCP server.

pub fn display_name(&self) -> String

Human-readable description for logging.

Trait Implementations

impl Clone for McpServerEntry

fn clone(&self) -> McpServerEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for McpServerEntry

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for McpServerEntry

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for McpServerEntry

fn eq(&self, other: &McpServerEntry) -> 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.

impl Serialize for McpServerEntry

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
