From 5b0774958afb21e0c9af0cd2e6f7cc36fd241b69 Mon Sep 17 00:00:00 2001 From: vikingowl Date: Wed, 3 Dec 2025 00:27:37 +0100 Subject: [PATCH] feat(auth): add multi-provider authentication with secure credential storage MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Authentication System: - Add credentials crate with keyring (OS keychain) and file fallback storage - Add auth-manager crate for unified auth across providers - Implement API key login flow for Anthropic, OpenAI, and Ollama Cloud - Add CLI commands: login, logout, auth (status) - Store credentials securely in macOS Keychain / GNOME Keyring / Windows Credential Manager API Key Helpers: - Support for password manager integration (1Password, Bitwarden, pass, AWS Secrets, Vault) - Command-based helpers with TTL caching - Priority chain: env vars ā†’ helpers ā†’ cache ā†’ stored credentials Background Token Refresh: - Automatic OAuth token refresh before expiration - Configurable check interval and refresh threshold MCP OAuth Support: - Add OAuth config to MCP server definitions - Support for SSE/HTTP transport with OAuth - Token storage with mcp: prefix Bug Fixes: - Fix keyring crate requiring explicit backend features (was using mock store) - Fix provider index not updated on credential store - Add User-Agent headers to avoid Cloudflare blocks šŸ¤– Generated with [Claude Code](https://claude.ai/claude-code) Co-Authored-By: Claude --- Cargo.toml | 2 + crates/app/cli/Cargo.toml | 5 + crates/app/cli/src/main.rs | 279 ++++++- crates/app/ui/src/app.rs | 32 +- crates/app/ui/src/lib.rs | 3 +- crates/core/agent/src/system_prompt.rs | 1 + crates/integration/mcp-client/src/lib.rs | 1 + crates/llm/anthropic/src/auth.rs | 27 +- crates/llm/core/src/lib.rs | 66 +- crates/llm/ollama/src/client.rs | 2 + crates/llm/openai/src/auth.rs | 23 +- crates/platform/auth/Cargo.toml | 33 + crates/platform/auth/src/lib.rs | 720 ++++++++++++++++++ crates/platform/auth/src/login.rs | 163 ++++ crates/platform/auth/src/refresh.rs | 358 +++++++++ crates/platform/credentials/Cargo.toml | 31 + crates/platform/credentials/src/file.rs | 260 +++++++ crates/platform/credentials/src/helpers.rs | 434 +++++++++++ .../platform/credentials/src/keyring_store.rs | 256 +++++++ crates/platform/credentials/src/lib.rs | 391 ++++++++++ crates/platform/plugins/src/lib.rs | 53 +- 21 files changed, 3100 insertions(+), 40 deletions(-) create mode 100644 crates/platform/auth/Cargo.toml create mode 100644 crates/platform/auth/src/lib.rs create mode 100644 crates/platform/auth/src/login.rs create mode 100644 crates/platform/auth/src/refresh.rs create mode 100644 crates/platform/credentials/Cargo.toml create mode 100644 crates/platform/credentials/src/file.rs create mode 100644 crates/platform/credentials/src/helpers.rs create mode 100644 crates/platform/credentials/src/keyring_store.rs create mode 100644 crates/platform/credentials/src/lib.rs diff --git a/Cargo.toml b/Cargo.toml index a41feab..6c5039b 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -7,7 +7,9 @@ members = [ "crates/llm/anthropic", "crates/llm/ollama", "crates/llm/openai", + "crates/platform/auth", "crates/platform/config", + "crates/platform/credentials", "crates/platform/hooks", "crates/platform/permissions", "crates/platform/plugins", diff --git a/crates/app/cli/Cargo.toml b/crates/app/cli/Cargo.toml index 389468c..9c1fbe0 100644 --- a/crates/app/cli/Cargo.toml +++ b/crates/app/cli/Cargo.toml @@ -14,9 +14,12 @@ color-eyre = "0.6" agent-core = { path = "../../core/agent" } llm-core = { path = "../../llm/core" } llm-ollama = { path = "../../llm/ollama" } +llm-anthropic = { path = "../../llm/anthropic" } +llm-openai = { path = "../../llm/openai" } tools-fs = { path = "../../tools/fs" } tools-bash = { path = "../../tools/bash" } tools-slash = { path = "../../tools/slash" } +auth-manager = { path = "../../platform/auth" } config-agent = { package = "config-agent", path = "../../platform/config" } permissions = { path = "../../platform/permissions" } hooks = { path = "../../platform/hooks" } @@ -24,6 +27,8 @@ plugins = { path = "../../platform/plugins" } ui = { path = "../ui" } atty = "0.2" futures-util = "0.3.31" +rpassword = "7" +open = "5" [dev-dependencies] assert_cmd = "2.0" diff --git a/crates/app/cli/src/main.rs b/crates/app/cli/src/main.rs index 9a35f69..28a0389 100644 --- a/crates/app/cli/src/main.rs +++ b/crates/app/cli/src/main.rs @@ -4,12 +4,15 @@ use clap::{Parser, ValueEnum};
