}

Connection configuration for one MCP server. Tag (transport) selects the wire transport; per-variant fields configure that transport.

Variants

Stdio

Spawn a child process and speak JSON-RPC over stdio.

Fields

command: String

args: Vec<String>

env: BTreeMap<String, String>

cwd: Option<PathBuf>

startup_timeout_ms: u64

call_timeout_ms: u64

StreamableHttp

Newer MCP spec HTTP/JSON streaming transport.

Fields

url: String

headers: BTreeMap<String, String>

startup_timeout_ms: u64

call_timeout_ms: u64

Sse

Older MCP spec HTTP+SSE transport.

Fields

url: String

headers: BTreeMap<String, String>

startup_timeout_ms: u64

call_timeout_ms: u64

Implementations

impl McpServerConfig

pub fn stdio(command: impl Into<String>, args: Vec<String>) -> Self

Convenience constructor for stdio servers.

pub fn streamable_http(url: impl Into<String>) -> Self

Convenience constructor for streamable-HTTP servers.

pub fn sse(url: impl Into<String>) -> Self

Convenience constructor for SSE servers.

pub fn startup_timeout(&self) -> Duration

pub fn call_timeout(&self) -> Duration

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

Formats the value using the given formatter.

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
