The MCP publishDocument tool required callers to pass approver_ids and to distinguish an omitted list (rejected) from an empty one (direct publish), a null-vs-empty subtlety that is awkward for an LLM to get right. Drop approver_ids from the MCP tool and resolve a major publish's approvers from the document's default approvers instead: an approval is requested when the document has default approvers, otherwise the version is published directly. Default approvers are configured with addDocument or updateDocument. Replace a document's default approvers on every major publish that supplies an explicit list, even when the list is empty, so a direct publish through the GraphQL API clears stale approvers instead of leaving them behind (previously the empty case skipped the update). Expose the default-approver behaviour as a separate entry point, PublishVersionWithDefaultApprovers, that loads the defaults and delegates to PublishVersion. PublishVersion keeps its explicit-approver contract for the GraphQL API. Require only the publish permission to publish a version, whether or not it opens an approval quorum, and drop the now-unused request-approval action. Fold the publish steps into the publishMinor and publishMajor primitives shared by both the single and bulk publish paths, and drop the redundant InTx suffix from RequestApproval and emitDocumentEvent, which already take a transaction argument.

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.
