MCP Server Framework and Tool Development library for building custom capabilities into agents.
b6b4cd0a4c
### Overview Major restructuring from monolithic `arcade-ai` package to modular library architecture with standardized uv-based dependency management.  ### New Package Structure - **`arcade-tdk`** - Lightweight toolkit development kit (core decorators, auth) - **`arcade-core`** - Core execution engine and catalog functionality - **`arcade-serve`** - FastAPI/MCP server components - **`arcade-ai`** - Meta package that includes CLI functionality. Optionally include evals via the `evals` extra. Optionally include all packages via the `all` extra. ### Key Benefits - **Lighter Dependencies**: Toolkits now depend only on `arcade-tdk` (~2 deps) vs full `arcade-ai` (~30+ deps) - **Faster Builds**: uv provides 10-100x faster dependency resolution and installation - **Better Modularity**: Clear separation of concerns, consumers import only what they need - **Standard Tooling**: Eliminates custom poetry scripts, uses standard Python packaging ### Migration Impact - All 20 toolkits converted from poetry → uv with `arcade-tdk` dependencies plus `arcade-ai[evals]` and `arcade-serve` dev dependencies. When developing locally, devs should install toolkits via `make install-local`. - Modern Python 3.10+ type hints throughout - Standardized build system with hatchling backend - Enhanced Makefile with robust toolkit management commands - Removed `arcade dev` CLI command - Reduce the number of files created by `arcade new` and add an option to not generate a tests and evals folder. This foundation enables faster development cycles and cleaner dependency chains for the growing toolkit ecosystem. ### Todo After this PR is merged - [ ] Post-merge workflow(s) (release & publish containers, etc) - [ ] Release order plan. @EricGustin suggests releasing in the following order: 1. `arcade-core` version 0.1.0 2. `arcade-serve` version 0.1.0 and `arcade-tdk` version 0.1.0 3. `arcade-ai` version 2.0.0 4. Patch release for all toolkits (all changes in toolkits are internal refactors) - [ ] [Update docs](https://github.com/ArcadeAI/docs/pull/318) --------- Co-authored-by: Eric Gustin <eric@arcade.dev> Co-authored-by: Eric Gustin <34000337+EricGustin@users.noreply.github.com> |

Arcade AI Platform
Arcade is a developer platform that lets you build, deploy, and manage tools for AI agents.
This repository contains the core Arcade libraries, organized as separate packages for maximum flexibility and modularity:
arcade-core- Core platform functionality and schemasarcade-tdk- Tool Development Kit with the@tooldecoratorarcade-serve- Serving infrastructure for workers and MCP serversarcade-evals- Evaluation framework for testing tool performancearcade-cli- Command-line interface for the Arcade platform
To learn more about Arcade.dev, check out our documentation.
Pst. hey, you, give us a star if you like it!
Quick Start
Installation
For development, install all packages with dependencies using uv workspace:
# Install all packages and dev dependencies
uv sync --extra all --dev
# Or use the Makefile (includes pre-commit hooks)
make install
For production use, install individual packages as needed:
pip install arcade-ai # CLI
pip install 'arcade-ai[evals]' # CLI + Evaluation framework
pip install 'arcade-ai[all]' # CLI + Serving infra + eval framework + TDK
pip install arcade_serve # Serving infrastructure
pip install arcade-tdk # Tool Development Kit
Development
Use the Makefile for standard tasks:
# Run tests
make test
# Run linting and type checking
make check
# Build all packages
make build
# See all available commands
make help
