Struct McpServerConfig 

pub struct McpServerConfig {
    pub transport: Option<McpTransportKind>,
    pub command: Option<String>,
    pub args: Vec<String>,
    pub env: Option<HashMap<String, String>>,
    pub cwd: Option<String>,
    pub url: Option<String>,
    pub headers: Option<HashMap<String, String>>,
}

MCP server definition stored in config.

Stdio: command + args. Remote: url (+ optional type / headers).

Fields

transport: Option<McpTransportKind>

Explicit transport (stdio | http | sse | auto).

command: Option<String>

Command to spawn (stdio transport)

args: Vec<String>

env: Option<HashMap<String, String>>

cwd: Option<String>

url: Option<String>

Remote MCP endpoint URL (Streamable HTTP or legacy SSE)

headers: Option<HashMap<String, String>>

Implementations

impl McpServerConfig

pub fn resolved_transport(&self) -> Result<McpTransportKind, String>

pub fn stdio_problem(&self) -> Option<String>

Why this stdio entry cannot work, before anything is spawned: an empty command, or a package runner (npx, uvx, …) given no package in args, which waits for input until the connect times out.

pub fn is_remote(&self) -> bool
