Employee document signatures recorded an acknowledgment with no cryptographic proof, unlike document approvals which already create and accept an electronic signature on every decision. Mirror the approval flow on the sign path: generate the signed document PDF, create-and-accept an esign record, and persist its id on the document_version_signatures row through a new electronic_signature_id column. Capture the signer IP and user agent in the resolver, and re-check the published/archived preconditions inside the transaction so the seal cannot race document state. Make the consent wording a single backend source of truth shared by the text that is sealed and the text shown in the UI. Define DocumentSignatureConsentText and DocumentApprovalConsentText in the probo service package and the NDA copy in the trust service, each owned by the flow that uses it, and stop esign from appending the generic clause to caller-provided consent text so approvals no longer seal a duplicated sentence. Expose the resolved consent text through GraphQL on EmployeeDocumentVersion and DocumentVersionApprovalDecision, and have the signing, approval, and NDA pages render it from the API instead of hard-coded strings, mirroring how the NDA page already worked. Align the wording with the actual interaction: the buttons read "Review and sign" and "Review and approve", the clauses reference those actions, and the inaccurate "typing my full name" phrasing is removed everywhere.

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. ISC 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.
