Permission-aware AI onboarding. An onboarding copilot inside IBM Bob that explains a codebase to a new engineer, and only the parts they are allowed to see.
Built for the IBM Bob 2.0 Hackathon (lablab.ai, 25 to 27 September 2026) by team Lawang Onboard.
The problem
A new engineer, or a contractor hired for one module, needs weeks to learn why a codebase looks the way it does. The answers exist, spread across commit messages, architecture decision records and pull request reviews, but nobody reads those on day one. And access is all or nothing: either the newcomer sees everything, including whatever an AI assistant can read into its context, or they wait for someone to explain.
What it does
Open the repository in IBM Bob, switch to the Onboard mode, and ask:
/tour: the map of what you can see, module by module./trace webhook: how a webhook becomes a record, step by step./why internal/ingress: the decisions and reviews behind a path.- "What can I pick up first?"
Bob answers from the code and its history, and cites every item it used. Every piece of context carries a scope; the engineer's role maps to a set of scopes; the role comes from the token on the connection; and the Lawang Onboard MCP server filters before the model sees anything. A contractor's session cannot leak what it was never given, and every answer ends with what was withheld:
Withheld: path:cmd (68), path:internal/core (314), path:migrations (56), path:repo (86), private:growth (18), private:security (6) | total hidden: 399

Questions
What is the lawang-onboard MCP server?
Onboarding copilot in IBM Bob that only shows what your role may see
Is lawang-onboard safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.
What credentials does lawang-onboard need?
It reads GITHUB_TOKEN, ONBOARD_TOKEN, ONBOARD_TOKEN_CONTRACTOR, ONBOARD_TOKEN_EMPLOYEE and ONBOARD_TOKEN_MAINTAINER from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.
How does lawang-onboard run?
It speaks stdio and streamable-http, so it runs as a local process your client starts.
How current is this page?
The grade is for one exact copy of the source (05fa16c39c88), read on 2026-10-11. The repository is watched and re-audited when it changes.
