name	openproject-codex
description	Use the OpenProject Codex plugin to inspect and manage work in Codex through the OpenProject API.

OpenProject Codex

Use this plugin when the user wants to work with OpenProject from Codex instead of using the OpenProject UI.

The plugin is intended to cover common project-management actions directly and then fall back to the generic authenticated API tool for any OpenProject module that is not yet represented by a dedicated MCP tool.

Behavior

• Prefer the MCP tools from this plugin for project, team, membership, and work package operations.
• Default to the configured OPENPROJECT_DEFAULT_PROJECT when present, unless the user explicitly asks for another project.
• Use openproject_connection_status first if credentials or connectivity are uncertain.
• If configuration is missing, use openproject_setup_connection to capture the base URL and API token directly from chat before attempting other actions.
• Use openproject_test_connection or openproject_whoami after setup when you need a quick verification step.
• API token authentication is preferred, but UI-session authentication is supported when OPENPROJECT_UI_USERNAME and OPENPROJECT_UI_PASSWORD are configured.
• Use openproject_list_types, openproject_list_statuses, openproject_list_priorities, and openproject_list_project_assignees before write operations when a value needs to be discovered.
• Use assignee_name, responsible_name, status_name, priority_name, and customer on openproject_create_work_package and openproject_update_work_package when the user provides human-readable values.
• Use openproject_list_custom_field_options or openproject_resolve_custom_field_option for Customer or other list-style custom fields instead of using the browser UI.
• Use dedicated tools first for projects, users, groups, memberships, versions, categories, queries, work packages, relations, watchers, comments, documents, news, time entries, attachments, file links, boards, wiki pages, meetings, reporting, and bulk task operations.
• Prefer openproject_my_work for “my items” or “items assigned to me” requests.
• Prefer the query tools when the user refers to saved views or wants bulk actions across a query result set.
• Prefer the bulk tools for repeated edits instead of issuing many single-item calls one by one.
• Prefer the reporting tools for workload, overdue, burndown, and project health export requests instead of assembling ad hoc summaries by hand.
• If the user needs an OpenProject action that does not yet have a dedicated tool, use openproject_call_api against the relevant /api/v3/... endpoint instead of sending the user back to OpenProject UI.
• The official OpenProject /mcp endpoint is read-only, so write operations should continue to use this plugin's API tools.
• Boards, wiki pages, and meetings may use authenticated UI-backed workflows when the public API surface is incomplete; ensure the UI credential env vars are configured before relying on those tools.

Required configuration

• OPENPROJECT_API_TOKEN is the preferred credential.
• OPENPROJECT_API_TOKEN_FILE is supported for local secret-file storage and is the recommended Codex desktop setup.
• OPENPROJECT_BASIC_API_TOKEN is supported as a fallback for legacy Basic auth with the apikey user.
• OPENPROJECT_BASIC_API_TOKEN_FILE is supported for the same legacy Basic-auth fallback.
• OPENPROJECT_BASE_URL is required.
• OPENPROJECT_DEFAULT_PROJECT is optional.
• OPENPROJECT_UI_USERNAME and OPENPROJECT_UI_PASSWORD are required for UI-session API fallback and the boards/wiki/meetings UI-backed tools.

The plugin can now persist this configuration locally through openproject_setup_connection, so the user does not have to edit .mcp.json manually on first use.

Typical flow

1. Check connection status.
2. Inspect projects, users, groups, memberships, versions, categories, or work packages.
3. Create, update, relate, watch, comment on, assign, or delete work through the MCP tools.
4. Use the bulk tools when the same change must be applied to many items.
5. Use openproject_call_api for unsupported modules or advanced API workflows.
