RiceCoder Enhanced Tools

Provides webfetch, patch, todo, and web search tools with hybrid MCP provider architecture.

Overview

Enhanced Tools implements a hybrid provider pattern where built-in implementations provide default functionality, while optional MCP servers can override or extend behavior for advanced use cases.

Architecture

All tools follow a provider priority chain:

1. MCP Server (if configured and available) - Custom implementations via external MCP servers
2. Built-in Implementation (fallback) - Default ricecoder implementation
3. Error (if both unavailable) - Report that tool is not available

This enables:

• Out-of-the-box functionality with built-in tools
• Advanced customization via custom MCP servers
• Graceful fallback when MCP is unavailable
• Zero configuration required for basic use

Modules

• error - Error types with context and suggestions
• result - Result types with metadata about execution
• provider - Provider trait and registry for tool implementations
• webfetch - Webfetch tool for fetching web content
• patch - Patch tool for applying unified diff patches
• [todo] - Todo tools for managing task lists
• search - Web search tool for searching the web

Example

use ricecoder_tools::provider::ProviderRegistry;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let registry = ProviderRegistry::new();

    // Register providers
    // registry.register_builtin_provider("webfetch", builtin_provider).await;

    // Get provider and execute
    // let provider = registry.get_provider("webfetch").await?;
    // let result = provider.execute("https://example.com").await?;

    Ok(())
}
