aura

Overview

Aura is a Rust-based framework for building and composing AI agents from declarative TOML configuration files. It provides MCP tool discovery across multiple transport protocols (HTTP, SSE, STDIO), automatic schema sanitization for OpenAI compatibility, and RAG pipeline integration with both in-memory and external vector stores. The framework supports multi-agent orchestration with a coordinator/worker architecture that enables dependency-aware, parallel execution with iterative re-planning capabilities.

After installing, here are 5 things you can ask your AI assistant:

• query_postgres

  Try:Show me the top 10 customers by revenueTry:List all users registered in the last week
• create_github_issue

  Create a new GitHub issue

  Try:Create a bug report for the login issueTry:Add a feature request for dark mode
• list_files

  List files in a directory

  Try:Show me all files in the current directoryTry:List Python files in the src folder
• read

  Read the contents of a file

  Try:Read the contents of config.tomlTry:Show me the README file
• find

  Find files matching a pattern

  Try:Find all Python files in the projectTry:Locate configuration files
• get_current_time

  Get the current time

  Try:What time is it now?Try:Show me the current timestamp

Note: Tool names were inferred from the documentation about client-side tools and examples. The README doesn't clearly document the specific MCP tools exposed by the server, only that it supports MCP tool discovery.

FAQ

How do I add MCP tools to my agent?

Configure tools in your TOML config file using the `tools` section. Aura supports dynamic MCP tool discovery across HTTP, SSE, and STDIO transports.

Can I use client-side tools?

Yes, but with caution. Set `enable_client_tools = true` in your agent configuration and optionally specify a `client_tool_filter` to limit available tools. This requires trusting the model and clients with local execution privileges.
