From f092d4cefd99343a0fa45ec7c5f9387f3e65d79e Mon Sep 17 00:00:00 2001 From: Ashwin Bhat Date: Thu, 20 Nov 2025 13:50:13 -0800 Subject: [PATCH] feat: add Microsoft Foundry provider support (#684) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * feat: add Azure AI Foundry provider support Add support for Azure AI Foundry as a fourth cloud provider option alongside Anthropic API, AWS Bedrock, and Google Vertex AI. Changes: - Add use_foundry input to enable Azure AI Foundry authentication - Add Azure environment variables (ANTHROPIC_FOUNDRY_RESOURCE, ANTHROPIC_FOUNDRY_API_KEY, ANTHROPIC_FOUNDRY_BASE_URL) - Support automatic base URL construction from resource name - Add validation logic with mutual exclusivity checks for all providers - Add comprehensive test coverage (7 Azure-specific tests, 3 mutual exclusivity tests) - Add complete Azure AI Foundry documentation with OIDC and API key authentication - Update README to reference Azure AI Foundry support Features: - Primary authentication via Microsoft Entra ID (OIDC) using azure/login action - Optional API key authentication fallback - Custom model deployment name support via ANTHROPIC_DEFAULT_*_MODEL variables - Clear validation error messages for missing configuration All tests pass (25 validation tests total). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude * refactor: rename Azure AI Foundry to Microsoft Foundry and remove API key support - Rename all references from "Azure AI Foundry" to "Microsoft Foundry" - Remove ANTHROPIC_FOUNDRY_API_KEY support (OIDC only) - Update documentation to reflect OIDC-only authentication - Update tests to remove API key test case 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude * docs: simplify Microsoft Foundry setup and remove URL auto-construction - Link to official docs instead of duplicating setup instructions - Remove automatic base URL construction from resource name - Pass ANTHROPIC_FOUNDRY_BASE_URL as-is 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --------- Co-authored-by: Claude --- README.md | 6 +- action.yml | 14 +++- base-action/action.yml | 12 ++++ base-action/src/validate-env.ts | 21 ++++-- base-action/test/validate-env.test.ts | 99 ++++++++++++++++++++++++++- docs/cloud-providers.md | 50 ++++++++++++-- 6 files changed, 189 insertions(+), 13 deletions(-) diff --git a/README.md b/README.md index b1c0f41..b8301f7 100644 --- a/README.md +++ b/README.md @@ -2,7 +2,7 @@ # Claude Code Action -A general-purpose [Claude Code](https://claude.ai/code) action for GitHub PRs and issues that can answer questions and implement code changes.
