From cbd70cbba4a19f0af0b5ac9cfd1203c231fef5d6 Mon Sep 17 00:00:00 2001 From: mjunaidca Date: Thu, 11 Dec 2025 06:02:45 +0500 Subject: [PATCH 1/6] feat: Enhance MCP Server with OAuth 2.0 Standardization This commit finalizes the implementation of OAuth 2.0 authentication for the TaskFlow MCP server, enabling seamless integration for CLI agents. Key updates include: - Introduced Device Flow for headless CLI authentication, allowing agents to authenticate without a browser. - Implemented JWT validation middleware for secure token handling. - Simplified tool signatures by removing user_id and access_token parameters, leveraging user context from middleware. - Updated ChatKit integration to utilize header-based authentication. These enhancements ensure that all MCP clients can authenticate using the standard Authorization: Bearer header, reinforcing the principle of agents as first-class citizens in the TaskFlow platform. --- helm/taskflow/templates/configmap.yaml | 7 +- helm/taskflow/values.yaml | 5 +- ...1-mcp-oauth-implementation.green.prompt.md | 91 +++++ .../src/taskflow_api/services/chat_agent.py | 11 +- .../taskflow_api/services/chatkit_server.py | 157 ++++---- packages/mcp-server/.env.example | 26 +- packages/mcp-server/pyproject.toml | 1 + packages/mcp-server/src/taskflow_mcp/auth.py | 355 +++++++++++++++++ .../mcp-server/src/taskflow_mcp/config.py | 10 +- .../mcp-server/src/taskflow_mcp/models.py | 40 +- .../mcp-server/src/taskflow_mcp/server.py | 207 +++++++++- .../src/taskflow_mcp/tools/projects.py | 14 +- .../src/taskflow_mcp/tools/tasks.py | 94 +++-- packages/mcp-server/tests/test_auth.py | 215 +++++++++++ packages/mcp-server/tests/test_models.py | 115 +++--- packages/mcp-server/uv.lock | 2 + .../012-task-search-filter-sort.md | 0 specs/014-mcp-oauth-standardization/plan.md | 254 ++++++++++++ specs/014-mcp-oauth-standardization/spec.md | 215 +++++++++++ specs/014-mcp-oauth-standardization/tasks.md | 202 ++++++++++ sso-platform/auth-schema.ts | 15 +- ..._cobra.sql => 0000_shocking_lionheart.sql} | 13 + .../src/app/admin/organizations/page.tsx | 8 +- sso-platform/src/app/auth/consent/page.tsx | 4 +- sso-platform/src/app/auth/device/page.tsx | 364 ++++++++++++++++++ .../src/app/auth/device/success/page.tsx | 63 +++ sso-platform/src/lib/auth.ts | 43 ++- sso-platform/src/lib/trusted-clients.ts | 116 +++++- 28 files changed, 2393 insertions(+), 254 deletions(-) create mode 100644 history/prompts/014-mcp-oauth-standardization/0001-mcp-oauth-implementation.green.prompt.md create mode 100644 packages/mcp-server/src/taskflow_mcp/auth.py create mode 100644 packages/mcp-server/tests/test_auth.py rename specs/{features => 012-task-search-filter-sort}/012-task-search-filter-sort.md (100%) create mode 100644 specs/014-mcp-oauth-standardization/plan.md create mode 100644 specs/014-mcp-oauth-standardization/spec.md create mode 100644 specs/014-mcp-oauth-standardization/tasks.md rename sso-platform/drizzle/{0000_messy_king_cobra.sql => 0000_shocking_lionheart.sql} (96%) create mode 100644 sso-platform/src/app/auth/device/page.tsx create mode 100644 sso-platform/src/app/auth/device/success/page.tsx diff --git a/helm/taskflow/templates/configmap.yaml b/helm/taskflow/templates/configmap.yaml index 9f5c41b..9c75903 100644 --- a/helm/taskflow/templates/configmap.yaml +++ b/helm/taskflow/templates/configmap.yaml @@ -58,8 +58,13 @@ metadata: {{- include "taskflow.componentLabels" (dict "root" .

Key updates include: - Added `verify_opaque_token` function to validate opaque tokens via the SSO userinfo endpoint. - Updated `get_current_user` to attempt JWT validation first, falling back to opaque token validation if necessary. - Enhanced audit logging to include client ID and client name for better traceability of actions performed by different OAuth clients. - Updated relevant routes and services to ensure consistent handling of both token types. These enhancements reinforce the platform's commitment to robust authentication mechanisms and improve the overall user experience for CLI agents and other clients. --- packages/api/src/taskflow_api/auth.py | 118 ++++++++++++++++-- .../api/src/taskflow_api/routers/tasks.py | 18 +++ .../api/src/taskflow_api/services/audit.py | 13 +- packages/mcp-server/src/taskflow_mcp/auth.py | 103 ++++++++++++--- .../mcp-server/src/taskflow_mcp/server.py | 2 +- packages/mcp-server/tests/test_auth.py | 57 +++++---- sso-platform/src/lib/auth.ts | 11 +- web-dashboard/src/app/agents/page.tsx | 66 ++++++++-- 8 files changed, 322 insertions(+), 66 deletions(-) diff --git a/packages/api/src/taskflow_api/auth.py b/packages/api/src/taskflow_api/auth.py index 494ef5c..903d4a3 100644 --- a/packages/api/src/taskflow_api/auth.py +++ b/packages/api/src/taskflow_api/auth.py @@ -1,10 +1,19 @@ """JWT/JWKS authentication against Better Auth SSO. -Flow: -1.

From 5020e38c9bf688ab7d28be4706bb9878fb1fba58 Mon Sep 17 00:00:00 2001 From: mjunaidca Date: Thu, 11 Dec 2025 07:32:32 +0500 Subject: [PATCH 3/6] feat(audit): Refactor audit detail formatting and enhance client information display This commit improves the AuditContent component by refining how audit details are formatted. Key changes include: - Excluded `client_id` and `client_name` from detail formatting to streamline the output. - Enhanced the display of client information by showing "via Client" when `client_name` is present. - Updated the layout to allow for better wrapping of audit entry details. These enhancements aim to improve the clarity and usability of the audit logs in the web dashboard, ensuring that relevant information is presented effectively. --- web-dashboard/src/app/audit/page.tsx | 20 +++++++++++++++----- web-dashboard/src/app/tasks/[id]/page.tsx | 8 +++++++- 2 files changed, 22 insertions(+), 6 deletions(-) diff --git a/web-dashboard/src/app/audit/page.tsx b/web-dashboard/src/app/audit/page.tsx index 26e23ee..b0096fb 100644 --- a/web-dashboard/src/app/audit/page.tsx +++ b/web-dashboard/src/app/audit/page.tsx @@ -100,11 +100,15 @@ function AuditContent() { } const formatDetails = (details: Record) => { - if (details.before !== undefined && details.after !== undefined) { - return `${details.before} โ†’ ${details.after}` + // Skip client_id and client_name - they're shown in the header + // eslint-disable-next-line @typescript-eslint/no-unused-vars + const { client_id, client_name, ...rest } = details + + if (rest.before !== undefined && rest.after !== undefined) { + return `${rest.before} โ†’ ${rest.after}` } - if (details.note) return String(details.note) - if (details.assignee_handle) return `Assigned to ${details.assignee_handle}` + if (rest.note) return String(rest.note) + if (rest.assignee_handle) return `Assigned to ${rest.assignee_handle}` return null } @@ -226,7 +230,7 @@ function AuditContent() { )}
