Versions: * arcade-mcp\==1.0.0rc1 * arcade-mcp-server\==1.0.0rc1 * arcade-core\==2.5.0rc1 * arcade-tdk\==2.6.0rc1 * arcade-serve\==2.2.0rc1 ### Summary Adds first-class MCP support across Arcade, introduces a new MCP server and CLI, unifies the project under the arcade-mcp name, overhauls templates/scaffolding, and improves developer tooling, secrets management, and examples. ### Highlights - **MCP Server & Core** - New MCP server with stdio and HTTP/SSE transports, session management, resumability, and lifecycle handling. - FastAPI-like `MCPApp` for building servers with lazy init; integrated worker+MCP HTTP app option. - Middleware system (logging and error handling), robust exception hierarchy, and Pydantic-based settings. - Async-safe managers for tools, resources, and prompts backed by registries and locks. - Developer-facing, transport-agnostic runtime context interfaces (logs, tools, prompts, resources, sampling, UI, notifications). - Conversion from Arcade ToolDefinition to MCP tool schema; OpenAI JSON tool schema converter. - Parser supports `@app.tool`/`@app.tool(...)` decorators. - **CLI** - New `mcp` command to run MCP servers with stdio or HTTP/SSE. - New `secret` command to set/list/unset tool secrets (supports .env input, preserves original casing for lookups). - `new` command refactored; option to create a full toolkit package with scaffolding. - `chat` command removed. - `serve.py` imports updated to `arcade_serve.fastapi.telemetry`; version retrieval now uses `arcade-mcp`. - `show.py` refactor to use new local catalog utilities. - `display_tool_details` improved: adds “Default” column and handles nested properties. - **Configuration & Discovery** - New `configure.py` to set up Claude Desktop, Cursor, and VS Code to connect to local or Arcade Cloud MCP servers. - Discovery utilities to find/install toolkits, build `ToolCatalog`s, analyze files for tools, load kits from directories (pyproject parsing), and build minimal toolkits. - Better handling of provider API key resolution and evaluation suite loading. - **Templates & Scaffolding** - Reorganized template structure (minimal vs full); moved `.pre-commit-config.yaml`, `.ruff.toml`, license, Makefile, README, tests, and tools layout to correct paths. - Minimal template adds `.env.example` for runtime secret injection. - Template pyproject updated for MCP servers; includes sample server with greeting and secret-reveal tools. - Authorization flow in templates simplified. - **Repo-wide Renaming & Examples** - Migrates references from `arcade-ai` to `arcade-mcp` across READMEs, scripts, and package metadata. - Examples updated (LangChain/LangGraph/AI SDK/TypeScript) and package name changed to `arcade-mcp-sdk`. - **Evals & Core Utilities** - Evals now use OpenAI tooling format (`OpenAIToolList`, `to_openai`); `tool_eval` takes `provider_api_key`. - Core utilities: fixed `does_function_return_value` by dedenting before parse; version bump to `2.5.0rc1` and dependency cleanup. - **Tooling & CI** - `setup-uv-env` action splits toolkit vs contrib dependency installation. - Pre-commit: excludes `libs/arcade-mcp-server/mkdocs.yml` and `libs/tests/` from YAML and Ruff hooks; Ruff per-file ignores (e.g., C901 in `libs/**/*.py`, TRY400 in server docs paths). - Makefile updates for uv env setup, quality checks, tests, builds, and new `shell` target. - Added Makefile to MCP server library to streamline dev workflow. - **Cleanup** - Removed `claude.json` config. - Simplified stdio entrypoint; removed unused imports (`arcade_gmail`, `arcade_search`). ### Breaking Changes - **CLI**: `chat` command removed; use `mcp`, `secret`, and updated `new`. - **Naming**: All users should update references from `arcade-ai` to `arcade-mcp`. - **Templates**: File paths moved; downstream scripts referencing old template locations may need updates. ### Getting Started - Run an MCP server: - `arcade mcp --stdio --toolkits your_toolkit` - `arcade mcp --http --toolkits your_toolkit` - Manage secrets: - `arcade secret set your_toolkit KEY=value` - `arcade secret list your_toolkit` - `arcade secret unset your_toolkit KEY` - Configure clients: - `arcade configure` to set up Claude Desktop, Cursor, and VS Code for local/Arcade Cloud MCP. --------- Co-authored-by: Sam Partee <sam@arcade-ai.com> Co-authored-by: Shub <125150494+shubcodes@users.noreply.github.com>

# Arcade MCP Examples
|
||
|
||
This directory contains examples demonstrating how to build MCP servers with your Arcade tools.
|
||
|
||
## Examples Overview
|
||
|
||
### Basic Examples
|
||
|
||
1. **[00_hello_world.py](00_hello_world.py)** – Minimal tool example
|
||
- Single `@tool` function showing the basics
|
||
- Run: `python -m arcade_mcp_server` (or `python -m arcade_mcp_server stdio`)
|
||
|
||
2. **[01_tools.py](01_tools.py)** – Creating tools and discovery
|
||
- Simple parameters, lists, and `TypedDict`
|
||
- How arcade_mcp_server discovers tools automatically
|
||
- Run: `python -m arcade_mcp_server`
|
||
|
||
3. **[02_building_apps.py](02_building_apps.py)** – Building apps with MCPApp
|
||
- Create an `MCPApp`, register tools with `@app.tool`
|
||
- Run HTTP: `python 02_building_apps.py`
|
||
- Run stdio: `python 02_building_apps.py stdio`
|
||
|
||
4. **[03_context.py](03_context.py)** – Using `Context`
|
||
- Access secrets, logging, and user context
|
||
- Run: `python -m arcade_mcp_server`
|
||
|
||
5. **[04_tool_secrets.py](04_tool_secrets.py)** – Working with secrets
|
||
- Use `requires_secrets` and access masked values
|
||
- Run: `python -m arcade_mcp_server`
|
||
|
||
6. **[05_logging.py](05_logging.py)** – Logging with MCP
|
||
- Demonstrates debug/info/warning/error levels and structured logs
|
||
- Run: `python 05_logging.py`
|
||
|
||
## Running Examples
|
||
|
||
Most examples can be run directly with the arcade_mcp_server CLI:
|
||
|
||
```bash
|
||
# Auto-discover tools in current directory
|
||
python -m arcade_mcp_server
|
||
|
||
# With specific transport
|
||
python -m arcade_mcp_server stdio # For Claude Desktop
|
||
python -m arcade_mcp_server # HTTP by default
|
||
|
||
# With debugging
|
||
python -m arcade_mcp_server --debug
|
||
|
||
# With hot reload (HTTP only)
|
||
python -m arcade_mcp_server --reload
|
||
```
|
||
|
||
For MCPApp examples, run the script directly to start an HTTP server.
