Struct ServerConfigBuilder 

pub struct ServerConfigBuilder { /* private fields */ }

Builder for constructing ServerConfig instances.

Provides a fluent API for building server configurations with optional arguments, environment variables, and HTTP settings.

Examples

use mcp_execution_core::ServerConfig;

// Stdio transport
let config = ServerConfig::builder()
    .command("mcp-server".to_string())
    .arg("--verbose".to_string())
    .env("DEBUG".to_string(), "1".to_string())
    .build();

// HTTP transport
let config = ServerConfig::builder()
    .http_transport("https://api.example.com/mcp".to_string())
    .header("Authorization".to_string(), "Bearer token".to_string())
    .build();

Implementations

impl ServerConfigBuilder

pub fn command(self, command: String) -> Self

Sets the command to execute.

Examples

use mcp_execution_core::ServerConfig;

let config = ServerConfig::builder()
    .command("docker".to_string())
    .build();

pub fn arg(self, arg: String) -> Self

Adds a single argument.

Examples

use mcp_execution_core::ServerConfig;

let config = ServerConfig::builder()
    .command("docker".to_string())
    .arg("run".to_string())
    .arg("--rm".to_string())
    .build();

pub fn args(self, args: Vec<String>) -> Self

Sets all arguments at once, replacing any previously added.

Examples

use mcp_execution_core::ServerConfig;

let config = ServerConfig::builder()
    .command("docker".to_string())
    .args(vec!["run".to_string(), "--rm".to_string()])
    .build();

pub fn env(self, key: String, value: String) -> Self

Adds a single environment variable.

Examples

use mcp_execution_core::ServerConfig;

let config = ServerConfig::builder()
    .command("mcp-server".to_string())
    .env("LOG_LEVEL".to_string(), "debug".to_string())
    .build();

pub fn environment(self, env: HashMap<String, String>) -> Self

Sets all environment variables at once, replacing any previously added.

Examples

use mcp_execution_core::ServerConfig;
use std::collections::HashMap;

let mut env_map = HashMap::new();
env_map.insert("DEBUG".to_string(), "1".to_string());

let config = ServerConfig::builder()
    .command("mcp-server".to_string())
    .environment(env_map)
    .build();

pub fn cwd(self, cwd: PathBuf) -> Self

Sets the working directory for the subprocess.

Examples

use mcp_execution_core::ServerConfig;
use std::path::PathBuf;

let config = ServerConfig::builder()
    .command("mcp-server".to_string())
    .cwd(PathBuf::from("/tmp"))
    .build();

pub fn http_transport(self, url: String) -> Self

Configures HTTP transport with the given URL.

This sets the transport type to HTTP and configures the endpoint URL.

Examples

use mcp_execution_core::ServerConfig;

let config = ServerConfig::builder()
    .http_transport("https://api.example.com/mcp".to_string())
    .build();

pub fn sse_transport(self, url: String) -> Self

Configures SSE transport with the given URL.

This sets the transport type to SSE (Server-Sent Events) and configures the endpoint URL.

Examples

use mcp_execution_core::ServerConfig;

let config = ServerConfig::builder()
    .sse_transport("https://api.example.com/sse".to_string())
    .build();

pub fn url(self, url: String) -> Self

Sets the URL for HTTP transport.

Examples

use mcp_execution_core::ServerConfig;

let config = ServerConfig::builder()
    .http_transport("https://api.example.com/mcp".to_string())
    .url("https://api.example.com/mcp/v2".to_string())
    .build();

pub fn header(self, key: String, value: String) -> Self

Adds a single HTTP header.

Examples

use mcp_execution_core::ServerConfig;

let config = ServerConfig::builder()
    .http_transport("https://api.example.com/mcp".to_string())
    .header("Authorization".to_string(), "Bearer token".to_string())
    .build();

pub fn headers(self, headers: HashMap<String, String>) -> Self

Sets all HTTP headers at once, replacing any previously added.

Examples

use mcp_execution_core::ServerConfig;
use std::collections::HashMap;

let mut headers = HashMap::new();
headers.insert("Authorization".to_string(), "Bearer token".to_string());

let config = ServerConfig::builder()
    .http_transport("https://api.example.com/mcp".to_string())
    .headers(headers)
    .build();

pub fn build(self) -> ServerConfig

Builds the ServerConfig.

Panics

Panics if:

• Command was not set for stdio transport
• URL was not set for HTTP transport

Use try_build() for fallible construction.

Examples

use mcp_execution_core::ServerConfig;

let config = ServerConfig::builder()
    .command("docker".to_string())
    .build();

pub fn try_build(self) -> Result<ServerConfig, String>

Attempts to build the ServerConfig, returning an error if invalid.

Errors

Returns an error if:

• Command is not set for stdio transport
• URL is not set for HTTP transport

Examples

use mcp_execution_core::ServerConfig;

let result = ServerConfig::builder()
    .command("docker".to_string())
    .try_build();

assert!(result.is_ok());
