Here's the PR summary:

## Enforce semver validation for `MCPApp` versioning
### Problem
`MCPApp.__init__` accepted any string as `version` with no validation.
Invalid versions like `"1.0.0dev"` or `"latest"` silently propagated to
the Engine, where `compareToolVersions` fell back to lexicographic
`strings.Compare` instead of `semver.Compare` — causing incorrect
ordering (e.g. `1.10.0 < 1.9.0`).
### Solution
Validate and normalize `version` at `MCPApp` instantiation time using
the same acceptance rules as Go's `golang.org/x/mod/semver v0.31.0` (the
exact version used by the Engine).
### Changes
**`arcade_mcp_server/_validation.py`** (new file)
- Shared regex constants: `SEMVER_PATTERN` (semver.org spec),
`SHORT_VERSION_PATTERN`, `MAJOR_ONLY_PATTERN`
**`arcade_mcp_server/mcp_app.py`**
- Added `_validate_version()` mirroring the existing `_validate_name()`
pattern
- Added `version` property + setter (validates on mutation too)
- `__init__` now stores `self._version` via `_validate_version()`
**`arcade_mcp_server/settings.py`**
- Added `@field_validator("version")` on `ServerSettings` — covers the
`MCP_SERVER_VERSION` env var path
- Fixed default from `"0.1.0dev"` → `"0.1.0"` (the old default was
itself invalid)
**`pyproject.toml`** — bumped `arcade-mcp-server` `1.17.4` → `1.17.5`
### Normalization pipeline
All inputs are normalized to canonical `MAJOR.MINOR.PATCH` before
storage:
| Input | Stored as |
|-------|-----------|
| `v1.0.0` | `1.0.0` |
| `1.0` / `v1.0` | `1.0.0` |
| `1` / `v1` | `1.0.0` |
### Verification
Validated against `golang.org/x/mod/semver v0.31.0` (Engine's exact
pinned version) — 40/40 accept/reject cases match. The Engine's own
`store_test.go` uses `"1.0"` and `"1.1"` as `ToolkitVersion` values,
confirming short forms are intentionally supported.
### Breaking change
Any user currently passing a non-semver version string (e.g.
`"1.0.0dev"`, `"latest"`) will get a `ValueError` on upgrade. This is
intentional — those versions were silently causing incorrect tool
ordering in the Engine.
Closes TOO-518

> [!NOTE]
> **Medium Risk**
> Introduces stricter version validation/normalization that will raise
errors for previously-accepted non-semver inputs (including via env

`ServerSettings`, rejecting invalid strings and normalizing accepted

`0.1.0dev` to `0.1.0`, tests are expanded to cover accept/reject cases,
and the package version is bumped to `1.17.5`.

## [TOO-522] Suppress chardet warning and fix OpenTelemetry telemetry
### Summary
Reduces noisy chardet/urllib3 warnings in telemetry and updates the
OpenTelemetry logger API to match the current SDK.
### Changes
**`libs/arcade-serve/arcade_serve/fastapi/telemetry.py`**
- Add `warnings.filterwarnings` to ignore `RequestsDependencyWarning`
when chardet≥6 is present (requests uses charset-normalizer regardless)
- Replace `_logs.set_logger_provider` with `set_logger_provider` from
`opentelemetry._logs` (API change in OpenTelemetry 1.15+)
**`.ruff.toml`**
- Add per-file ignore for E402 on `telemetry.py` because
`warnings.filterwarnings` must run before the opentelemetry imports that
pull in requests
**`libs/arcade-serve/pyproject.toml`**
- Bump version 3.2.1 → 3.2.2

Closes TOO-522

Fixes [PLT-720: Refactor CLI to support multiple orgs +
projects](https://linear.app/arcadedev/issue/PLT-720/refactor-cli-to-support-multiple-orgs-projects)
This PR removes the legacy login flow (login to get an API key) from
Arcade CLI. Believe it or not, this flow predates the ability to get an
API key from the Dashboard, or even the Dashboard itself!
Notable changes:
**Legacy handling** - When a user with an existing `credentials.yaml`
updates the CLI, they will get instructions on fixing their old
credentials:

Any commands that require login (non-public commands) will be blocked
with the above message until `arcade logout / arcade login` is performed
again.

# Valuable references for the reviewer:
- Docs PR: https://github.com/ArcadeAI/docs/pull/583
- Implements Phase 1 of the following planning doc:
https://linear.app/arcadedev/project/arcade-mcp-supports-mcp-auth-front-door-auth-7cbaa20cb054/overviewhttps://github.com/user-attachments/assets/79ad43fd-f5e8-4793-a1dd-18b35acefdc3
# PR Description
Adds OAuth 2.1 Resource Server authentication to arcade-mcp-server,
enabling HTTP MCP servers to validate Bearer tokens on every request.
This unlocks tool-level authorization and secrets support for HTTP
servers.
- Multiple authorization server support
- Granular token validation options (verify_exp, verify_iat, verify_iss)
- Environment variable configuration
- OAuth discovery metadata endpoint
(/.well-known/oauth-protected-resource)
- Extracts sub claim from token as context.user_id
- Lifts transport restrictions for tools requiring auth/secrets on HTTP
when protected
```python
from arcade_mcp_server import MCPApp
from arcade_mcp_server.resource_server import ResourceServerAuth, AuthorizationServerEntry
resource_server_auth = ResourceServerAuth(
canonical_url="http://127.0.0.1:8000/mcp",
authorization_servers=[
AuthorizationServerEntry(
authorization_server_url="https://auth.example.com",
issuer="https://auth.example.com",
jwks_uri="https://auth.example.com/jwks",
)
],
)
app = MCPApp(name="my_server", version="1.0.0", auth=resource_server_auth)
```
# Testing
Beyond the comprehensive unit tests, I also manually tested end-to-end
with WorkOS Authkit (DCR) and KeyCloak (non-DCR).
# Future Work
- CIMD support
- An `ArcadeResourceServer` to make adding front-door auth super easy
when using Arcade's Auth Server
<!-- CURSOR_SUMMARY -->
---
> [!NOTE]
> Adds OAuth 2.1 front-door auth (JWKS validation + OAuth discovery) and
propagates user identity to tools, enabling auth/secret-requiring tools
over HTTP.
>
> - **Authentication (Front-Door OAuth 2.1)**
> - New `resource_server` module with `ResourceServerAuth`
(multi-authorization-server, metadata) and `JWKSTokenValidator`
(JWKS-based JWT validation) plus granular validation options.
> - ASGI `ResourceServerMiddleware` validates Bearer tokens on every
HTTP request and injects `resource_owner`.
> - OAuth discovery endpoint via FastAPI router at
`/.well-known/oauth-protected-resource[/<path>]`.
> - **Integration**
> - `MCPApp`/`worker` accept `auth`/`resource_server_validator`, mount
middleware, expose discovery; logs accepted auth servers.
> - HTTP transport (`http_streamable`) carries `SessionMessage` with
`resource_owner` from request → session.
> - `Context`/`Session`/`Server` plumb `resource_owner`; `Server`
selects `user_id` preferring token `sub`.
> - **Behavior Changes**
> - HTTP transport restriction lifted for tools requiring
`authorization`/`secrets` when request is authenticated; otherwise
blocked with actionable error.
> - **Configuration**
> - Env-var based auth config via `MCP_RESOURCE_SERVER_*` in
`MCPSettings.ResourceServerSettings`; `.env` auto-load.
> - **Telemetry**
> - Usage tracking records `resource_server_type` on server start.
> - **Examples**
> - New `examples/mcp_servers/authorization` sample server (HTTP auth,
secrets, Reddit tool) with Docker setup.
> - **Tests**
> - Extensive unit tests for validators, middleware, env config,
multi-AS, transport rules, and app integration.
> - **Version**
> - Bump `arcade-mcp-server` to `1.12.0`; minor docstring tweak in
`__init__.py`.

Update `arcade-core` and `arcade-tdk` dependency versions to resolve
`ImportError` caused by incompatible `Figma` auth provider imports.
The `Figma` OAuth2 provider was introduced in `arcade-core` 3.3.5.
`arcade-tdk` 3.2.0 and `arcade-mcp-server` 1.10.2 started importing
`Figma`, but their `pyproject.toml` dependency constraints were not
updated to require `arcade-core>=3.3.5`. This led to `ImportError` when
`arcade-tdk` or `arcade-mcp-server` were installed with an older
`arcade-core` version. This PR updates the minimum required versions in
`pyproject.toml` files across `arcade-tdk`, `arcade-mcp-server`, and the
root project to ensure compatibility.

This PR does three things:
1. Executes synchronous tool calls in thread pool allowing for up to 4 +
# of CPUs executions in parallel.
2. Makes force quitting via double SIGINT/SIGTERM possible and via
single SIGINT/SIGTERM + graceful shutdown timeout expiry possible, even
if there are active connections.
3. Sets `timeout_graceful_shutdown` to
`ARCADE_UVICORN_TIMEOUT_GRACEFUL_SHUTDOWN` env var if set, else defaults
to 15.
4. Disable the worker health check span to reduce noise
Tradeoffs:
Since this PR introduces executing synchronous tools via `await
asyncio.to_thread(func, **func_args)`, this means that there is no way
for the thread to be killed until it finishes. The ramifications of this
is that the force quitting logic that is also implemented in this PR has
to be very harsh `os._exit(1)` just in case there is a sync tool
actively executing. This means that `MCPApp` teardown logic will not
execute when force quitting is required. Although this was already the
case because we weren't previously able to force quit! This tradeoff is
justified for now since "parallel" tool executions will relieve us of
many worker timeouts that we are seeing in prod.
Future work:
Minimize/eliminate the need for `os._exit(1)` such that `MCPApp`
teardown logic will always execute, even when force quitting. The
solution will likely be moving away from `await asyncio.to_thread(func,
**func_args)` (while maintaining "parallelism" and then utilize the
`TaskTrackerMiddleware` introduced in this PR to cancel all of the
active HTTP requests.

…ng in WSL
When running `arcade configure claude` in WSL, the configuration file
was being written to the WSL filesystem
(~/.config/Claude/claude_desktop_config.json) instead of the Windows
AppData directory where Claude Desktop actually reads it.
This commit adds:
- WSL detection via WSL_DISTRO_NAME env var and /proc/version
- Windows username retrieval when running in WSL
- Updated config path functions to use Windows paths when in WSL
- Applied the same fix to Cursor and VS Code config paths for
consistency
The fix ensures that when running in WSL, the config file is written to:
/mnt/c/Users/{username}/AppData/Roaming/Claude/claude_desktop_config.json
This allows Claude Desktop on Windows to properly detect and use the MCP
server configuration.
