### 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.

Small update to reflect some changes to the `langchain-arcade` package
in the last release.
---------
Co-authored-by: Eric Gustin <34000337+EricGustin@users.noreply.github.com>
- **New Class Structure**: Introduced `ToolManager` and
`AsyncToolManager` classes (`ArcadeToolManager` is deprecated)
- **Async Support**: Full async implementation for modern LangChain
applications
- **Better Tool Management**: New methods for adding individual tools
and toolkits
- **CI/CD**: for langchain_arcade
## Upgrade Changes
```python
# Old pattern
manager = ArcadeToolManager(api_key="...")
tools = manager.get_tools(toolkits=["Google"])
# New pattern
manager = ToolManager(api_key="...")
manager.init_tools(toolkits=["Google"])
tools = manager.to_langchain()
```
Now supports underscores vs dots in tool names for better model
compatibility.
# PR Description
* This PR updates code in `examples/` to be compatible with version
1.0.0
* This PR removes the Spotify examples since the Arcade hosted worker
doesn't currently cataloge the Spotify toolkit. We can reintroduce these
examples when it does.
* This PR performs various renames across the codebase for
`arcade-ai.com` --> `arcade.dev` and `Arcade AI` --> `Arcade`
This PR updates the LangChain Arcade integration to v1.0.0, making the
following key changes:
• Bumped the package version in pyproject.toml from 0.2.0 to 1.0.0.
• Changed the default parameter in ArcadeToolManager from
langgraph=False to langgraph=True.
• Updated dependencies to require langgraph≥0.2.67,<0.3.0 and simplified
extras.
• Adjusted example scripts to remove explicit authorization_url
references in favor of a unified URL field.
• Updated docs and environment references to align with new usage
patterns and emphasize environment variables.
These changes unify and streamline the LangGraph-based tooling while
ensuring compatibility with the latest 1.0.0 release.
**PR Description**
This update bumps the integration’s version to `0.2.0` and brings
several important changes to how `langchain-arcade` interfaces with
Arcade tools:
1. **Updated Tool Definition Imports**
• Replaces `arcadepy.types.shared.ToolDefinition` with
`arcadepy.types.ToolGetResponse as ToolDefinition`.
• The parameter extraction is now done via `tool_def.input.parameters`
instead of the previous `tool_def.inputs.parameters`.
2. **Authorization Flow Adjustments**
• Uses `auth_response.url` instead of `auth_response.authorization_url`.
• The `authorize` and `is_authorized` methods now rely on the Arcade
client’s updated arguments (`client.auth.status(id=authorization_id)`).
3. **Tool Execution Parameter Renaming**
• The `execute` method now expects `input=kwargs` instead of
`inputs=kwargs`, aligning with Arcade’s new API spec.
4. **Tool Retrieval Enhancements**
• `_retrieve_tool_definitions` is revised to better handle pagination
and tool listing (including when no tools/toolkits are explicitly
provided).
5. **Version & Dependency Updates**
• Increases `langchain-arcade` to `0.2.0`.
• Switches `arcadepy` dependency to `~1.0.0rc1`.
• Updates example requirements to consume
`langchain-arcade[langgraph]>=0.2.0`.
These changes may affect existing code that relies on older parameter
names (`inputs.parameters` → `input.parameters`) and the renamed execute
argument. Please ensure any integrations or custom usage of Arcade tools
is updated accordingly.
On the last few PRs I have noticed two problems:
1. `ruff format` fails even though it seems OK on our local machines
(sometimes, not always)
2. Nate's and Sam's machines kept flip-flopping a specific piece of
formatting back and forth, indicating a subtle difference of config
hiding somewhere
3. This was reproducible by running `ruff format` in the terminal,
followed by `make check`. The former would edit files, and then `make
check` would edit them back!
This PR addresses both issues, and further standardizes our editor &
linter configs to be super stable.
Specifically:
1. The main fix for the above, the pre-commit hook was pinned to a super
old version of ruff.
This resulted in subtle differences in behavior between our machines,
and on CI.
2. Moved ruff settings from `pyproject.toml` to `.ruff.toml`
pyproject files in subdirectories (e.g. `toolkits/**`) were overriding
the main pyproject file and erasing the custom ruff config we set at the
root. This meant that our ruff config was applied to `arcade` but not to
any of the other packages.
By moving the config to `.ruff.toml` at the root, all projects will
inherit the same ruff linting & formatting config.
4. Un-ignored the `.vscode/` directory so that we can share
vscode/cursor workspace settings.
This is valuable for standardizing settings like the default formatter
(ruff) and default test framework (pytest).
However, it's important that going forward we _only_ commit things here
that should apply across all of our machines.
5. To avoid any conflict between prettier and ruff, prettier now
explicitly ignores *.py files
6. Finally, `ruff format` and `make check` agree. A number of files are
newly auto-formatted.
This PR includes several improvements to the Arcade client and adds
LangGraph examples:
1. Enhanced error handling in the Arcade client:
- Improved HTTP error handling in `BaseArcadeClient`
- Simplified request methods in `SyncArcadeClient` and
`AsyncArcadeClient`
2. Updated `ToolResource` class:
- Changed base path from `/v1/tool` to `/v1/tools`
- Added `tool_version` parameter to `authorize` method
3. Improved Toolkit discovery:
- Updated `find_all_arcade_toolkits` to search only in the current
Python interpreter's site-packages
5. Added LangGraph examples:
- New `langgraph_auth.py` example demonstrating Gmail authentication
- New `langgraph_with_tool_exec.py` example showing tool execution
within a LangGraph
6. Minor updates:
- Changed default `BASE_URL` to `https://api.arcade.com/`
- Updated import error message for eval dependencies
