Three defects, all found reviewing the rebased branch. The connection probe hit /v1alpha/accounts, which any analytics.readonly grant can call, while the driver's first request is the account's accessBindings — that additionally needs Administrator on the account and the manage.users.readonly scope. An Editor connecting, or a user declining the second scope on Google's granular consent screen, probed green and then 403'd on every campaign fetch, leaving the source permanently "Connected" with no rows. The probe now targets the same accessBindings collection the driver reads. A single unreadable property aborted the whole account. A property the token cannot see, or one deleted between the list and the read, threw away every binding already collected; 49 of 50 readable properties are still worth reviewing, so 403 and 404 now skip that property. Anything else still fails the fetch. Fan-out errors named no resource: the account call, the property list and each per-property call all returned the same "unexpected status" string, so a 403 on one subproperty out of forty was unattributable. Errors now carry the account or property ID. The cassette gains a subproperty parented to another property (only reachable through the ancestor filter, so it pins the hierarchy walk that the filter change claimed) and a property returning 403.

Probo
Open-source GRC platform for engineers.
Probo is a self-hostable governance, risk, and compliance (GRC) platform built for engineering and security teams. It covers the full GRC lifecycle: risk identification, control tracking, vendor risk, data privacy, access reviews, audit programs, and document approval workflows. Every entity is accessible through a web console, a CLI, a Model Context Protocol (MCP) API, and a GraphQL API, so you can automate compliance work from code, scripts, or any LLM agent.
Why Probo?
- AI-native by design. 270+ MCP tools expose every entity and operation. Any MCP-compatible LLM agent can read and write your GRC data, draft policies, run risk assessments, and generate evidence packs.
- Full GRC coverage. Risk management, controls, vendor risk, data privacy (DPIA/TIA), access reviews, audit programs.
- Multiple interfaces. Web console,
prbCLI (44+ command groups), MCP API, GraphQL, and an n8n community node for no-code automation. - Open source and self-hostable. MIT licensed. Run it on your own infrastructure with Docker.
- Audit-ready. Policy-based RBAC, immutable audit logs, electronic document sign-off workflows, and evidence chains.

Interfaces
Web console
The primary interface for day-to-day GRC work. Runs at http://localhost:8080 in development.
CLI (prb)
A fully-featured command-line client for scripting, automation, and CI/CD integration. Covers all 44+ resource types available in the web console.
# Authenticate
prb auth login
# List open risks
prb risk list
# Create a measure and link evidence
prb measure create --name "MFA enforced on all production systems"
prb evidence create --measure <id> --file screenshot.png
# Manage vendor compliance
prb thirdpartymgmt vendor list
prb thirdpartymgmt risk-assessment create --vendor <id>
Run prb help for the full command reference.
MCP API
Probo exposes 270+ MCP tools covering every entity and operation in the platform. Any MCP-compatible LLM agent (Claude, Cursor, Continue, and others) can connect directly and interact with your compliance data.
The full MCP specification is at pkg/server/api/mcp/v1/specification.yaml.
n8n node
The @probo/n8n-nodes-probo community node brings Probo into n8n workflows for no-code automation of compliance tasks over the GraphQL API.
