Tools the caller cannot use, because of plan tier or role permission, are filtered out before the model ever sees them, so an agent never burns a turn calling something it was never allowed to call. The other detail worth knowing when an agent reads other people's writing: task titles, comment bodies and wiki text are wrapped for prompt-injection containment before they reach the model's context, which is the failure mode most tools that return user-generated content ignore.
Onplana's public MCP server, exposing the portfolio — projects, tasks, sprints, milestones, risks and org knowledge — to any client that speaks Streamable HTTP. It is listed in the ChatGPT and Claude connector directories, so on those clients it connects by name with no URL to paste, and the transport layer behind it is published as open source.
- Read and search: list_projects, get_project with tasks, milestones and recent activity, list_tasks, get_task with dependencies and subtasks, list_org_members for resolving an assignee by name, and list_risks from automated risk detection.
- search_org_knowledge is the differentiator — hybrid vector and BM25 search across projects, tasks, risks, goals, comments and wiki pages.
- find_similar_projects and summarize_project, for orientation on a portfolio you did not build.
- Mutations: create_project, update_project, create_task, update_task, assign_task, move_task_to_sprint, add_project_member, create_milestone and create_comment.
- Bulk and agentic work: bulk_update_tasks, create_sprint_with_tasks and analyze_project_risks.
- Every project, task, sprint, milestone, issue and cited source read back carries a canonical link that opens the exact record in the app.
- The highlighted tools are a slice of a much larger catalog reaching governance, change control, timesheets, documents, wikis and portfolios.
An Onplana account, authorised over OAuth 2.1 — dynamic client registration is supported, so a capable client can register itself — or with a personal access token from the integrations page. Nothing to install: point a Streamable HTTP client at the hosted endpoint. Tokens are scoped, revocable and audited.
