Probo

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, prb CLI (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.
