Configuration for a single MCP server

Fields

command: Option<String>

args: Vec<String>

env: HashMap<String, String>

url: Option<String>

transport: Option<String>

Explicit transport selector (stdio | sse | http). When omitted, the transport is inferred: command ⇒ stdio, url ⇒ sse. Set to http to use the 2025 Streamable HTTP transport. Accepts the type alias for compatibility with common mcp.json snippets.

headers: HashMap<String, String>

Extra HTTP headers for remote transports (sse / http). Values may use ${ENV_VAR} placeholders — prefer env indirection over plaintext secrets in mcp.json.

auth: Option<McpAuthConfig>

Shorthand auth (type: bearer | apiKey). Merged before headers; explicit headers entries override auth defaults.

connect_timeout: Option<u64>

execute_timeout: Option<u64>

read_timeout: Option<u64>

disabled: bool

enabled: bool

required: bool

enabled_tools: Vec<String>

disabled_tools: Vec<String>

Implementations

impl McpServerConfig

pub fn resolve_http_headers( &self, server_name: &str, ) -> Result<HashMap<String, String>, Error>

Resolve HTTP headers for remote transports: explicit headers, plus shorthand auth, with ${VAR} / $VAR env substitution.

pub fn redacted_for_display(&self) -> McpServerConfig

Return a copy safe to expose over HTTP APIs (secrets redacted).

impl McpServerConfig

pub fn effective_connect_timeout(&self, global: &McpTimeouts) -> u64

pub fn effective_execute_timeout(&self, global: &McpTimeouts) -> u64

pub fn effective_read_timeout(&self, global: &McpTimeouts) -> u64

pub fn is_enabled(&self) -> bool

pub fn transport_kind(&self) -> Result<McpTransportKind, Error>

Resolve the effective transport for this server.

Honors the explicit transport/type field when present, otherwise infers from command (stdio) vs url (SSE, preserving pre-Streamable behavior). Returns an error when the config is ambiguous or incomplete.

pub fn is_tool_enabled(&self, tool_name: &str) -> bool

Trait Implementations

impl Clone for McpServerConfig

fn clone(&self) -> McpServerConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for McpServerConfig

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for McpServerConfig

fn deserialize<__D>( __deserializer: __D, ) -> Result<McpServerConfig, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for McpServerConfig

impl PartialEq for McpServerConfig

fn eq(&self, other: &McpServerConfig) -> 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 McpServerConfig

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
