Struct McpServerConfig 

pub struct McpServerConfig {
    pub name: String,
    pub command: String,
    pub args: Vec<String>,
    pub env: HashMap<String, String>,
    pub cwd: Option<String>,
}

Configuration for a single MCP server.

Security

env is where the de-facto .mcp.json format puts server credentials, so its values never reach Debug output: the rendering keeps the variable names, which is what an operator needs to see, and replaces every value. Serialize is unaffected — a config written back to disk still carries the values it was given.

Fields

name: String

Display name for the server.

command: String

The command to spawn.

args: Vec<String>

Arguments to pass to the command.

env: HashMap<String, String>

Extra environment variables.

Values are redacted by Debug; see the type’s security note.

cwd: Option<String>

Working directory for the spawned process.

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

Renders every field except the environment values.

Written by hand rather than derived so that formatting a config for a log, an error, or a panic cannot print a token. The remaining fields stay visible because command and args are how an operator identifies which server the configuration describes.

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

Equality operator ==.

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

Inequality operator !=.

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.
