BLACKPROOF AGPL MCP Server

BLACKPROOF

BLACKPROOF is a free, open-source, local-first cyber evidence app under AGPL-3.0-only. Create, import, encrypt, export and verify dossiers directly in your browser. No account, activation key or application server is required. Use it to prepare cyber reviews, internal audits and supplier questionnaires. Bring your own review checklist, document answers, evidence references and reservations, then track the remaining preparation work. Source documents and audit conclusions still require human assessment; this is not a system scanner or an automated certification service.

Core flow:

questionnaire ou grille d'audit → réponses et références → preuves attendues → points à corriger → dossier interne → export relu facultatif.

Project structure

• apps/web — public website and local-first app
• apps/web/src/content/analyses (sourced Markdown analyses and publication drafts)
• packages/core — ProofGraph, ProofDebt, ProofPack logic
• packages/verifier — standalone Delivery verifier CLI/SDK
• packages/mcp — local, read-only MCP server for minimized verification and comparison
• tests/e2e — Chromium tests for the local-first editor and verification flows
• scripts — schema generation, security checks and deployment tooling
• docs — project context and technical documentation

Development

Requirements: Node.js 22.23.2 (see .nvmrc) and pnpm 10.34.5.

pnpm install --frozen-lockfile
pnpm dev

The authoritative local gate is:

pnpm verify:all

pnpm verify:all runs schema drift checks, TypeScript/Astro/Svelte validation, unit tests, the static build, CSP generation, local-only artifact checks, the dependency and repository security audits, and the Chromium end-to-end tests.

Local-first boundary

Questionnaires, ProofPacks and Delivery snapshots are processed on the user's device; saved dossiers are encrypted in browser IndexedDB. No server upload is implemented or permitted for import, creation, editing, backup or verification. Downloading an export saves a local file; users transmit it separately, outside BLACKPROOF. See docs/LOCAL_FIRST_STORAGE.md and docs/SECURITY_MODEL.md before changing a storage, export or destructive operation.

Local MCP for enterprise agents

Use the local MCP server to check a selected ProofPack before transmission, compare two review snapshots through aggregate changes, and obtain public preparation checklists for cyber reviews, internal audits and questionnaires. It does not expose answers, evidence references or files to the agent. It runs over stdio on the user's device, not on the public website.

See installation, tools, fictional walkthrough and security limits. Private mode requires an end-to-end local client/model. A local transport alone cannot stop a host from forwarding results to a remote model.

Editorial analyses

The /analyses section is generated from a validated Astro content collection. Drafts are excluded from public routes, RSS and the sitemap. The complete authoring and verification workflow is documented in docs/EDITORIAL_ANALYSES.md.

Licence and contributions

The original software, documentation, schemas and standalone verifier are licensed under GNU AGPL version 3 only. See LICENSE and NOTICE. Third-party dependencies retain their own licences in THIRD_PARTY_NOTICES.md. Contributions are welcome: see CONTRIBUTING.md. Project names and logos are covered separately by TRADEMARKS.md.

Self-hosting

pnpm build produces the static site in apps/web/dist/. Serve it over HTTPS (or localhost for development), with the CSP and security headers described in docs/DEPLOY_APACHE.md. Publish the corresponding source of your version and keep the licence/source link visible.

The application stores dossiers locally in browser IndexedDB. Back up encrypted dossiers before changing hostname or browser profile: browser storage is scoped to an origin and is not synchronized by the host.

The hosted public status registry is retired. Local verification and detached signatures remain available. A historical or unavailable registry must never be interpreted as proof that a Delivery is currently active.
