Bynn
Document fraud detection for manipulated, fake and AI-generated PDF and image documents.
Install
Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).
claude mcp add --transport http bynn 'https://mcp.bynn.com'{
"mcpServers": {
"bynn": {
"type": "http",
"url": "https://mcp.bynn.com"

Bynn Agent Skills
Official Agent Skills for Bynn, ZOREAL, Agemin, and
Detector24. They teach any coding agent how to integrate document fraud detection for
manipulated, fake and AI-generated PDF and image documents, plus identity verification,
proof-of-human sign-in and meetings, age verification, and content detection, including the
parts that are easy to get subtly and dangerously wrong. The onboarding below also installs
the DecisionNode skill from its own repository,
decision-node-skills.
Works with Claude Code, Cursor, Codex, Copilot, Gemini CLI, OpenCode, Windsurf, Zed, and
every other agent the skills CLI supports.
Onboard an agent in one shot
Paste this line into any coding agent and it installs the Bynn, ZOREAL, DecisionNode,
Agemin and Detector24 skills plus the MCP servers itself, following
agent-setup.md:
Set up Bynn, ZOREAL, DecisionNode, Agemin and Detector24 for me: fetch https://bynn.com/agent-setup.md and follow it.It covers Claude Code, Cursor, VS Code, Windsurf, Zed, Claude Desktop, ChatGPT, and headless or CI setups, and tells the agent what to verify before it reports success.
https://bynn.com/agent-setup.md serves this repository's
agent-setup.md as it is; its source is
https://github.com/Bynn-Intelligence/skills/blob/main/agent-setup.md.
Install
Any agent:
npx skills add Bynn-Intelligence/skillsThe installer shows a picker grouped by product (Bynn, ZOREAL, Agemin, Detector24), so you can
toggle a whole product with one keypress on its group header. Press a to select
everything. Nothing is pre-selected, which is the CLI's behaviour and not configurable
per repository.
To skip the picker entirely:
# every skill, every detected agent, no prompts
npx skills add Bynn-Intelligence/skills --all
# every skill, but choose the agents yourself
npx skills add Bynn-Intelligence/skills --skill '*'
# just one product's skills
npx skills add Bynn-Intelligence/skills --skill bynn --skill bynn-mcp --skill bynn-kyc-sessionsRunning inside a coding agent skips the picker on its own and installs everything.
Claude Code, with the bundled MCP server:
/plugin marketplace add Bynn-Intelligence/skills
/plugin install bynn@bynn
/plugin install zoreal@bynnDecisionNode is installed from its own marketplace:
/plugin marketplace add Bynn-Intelligence/decision-node-skills
/plugin install decisionnode@decisionnodeWhat is in here
bynn
The identity platform. Start with the bynn skill: it routes to the rest.
| Skill | Covers |
|---|---|
bynn | Router. Auth model, API base, errors, conventions. |
bynn-mcp | Connecting an agent to mcp.bynn.com and driving Bynn through tools. |
bynn-document-fraud | Forgery, tampering, and AI-generation analysis of documents. |
bynn-kyc-sessions | Identity verification sessions: liveness, NFC chip reads, preflight. |
bynn-web-sdk | Embedding verification in a website with @bynn-intelligence/websdk. |
bynn-age-verification | Age estimation and minor detection, selfie and liveness. |
bynn-moderation | Every detection model over image, video, text, and audio. |
bynn-face-search | Face collections, enrollment, and 1:N search. |
bynn-autodoc | Document requests sent over email or SMS. |
bynn-webhooks | Payloads, the event catalogue, and signature verification. |
zoreal
ZOREAL, the trust layer that proves a real human is present behind a digital interaction.
| Skill | Covers |
|---|---|
zoreal | Router. What each ZOREAL product proves, and why ZOREAL Verify work goes through the Bynn skills. |
zoreal-identify | Login with ZOREAL: the client libraries, scopes, requiring a live human with acr, the assurance block. |
zoreal-meet | The ZOREAL Meet meetings API, host controls and the presence rule, and the ZOREAL Book embed. |
ZOREAL Verify, which includes PDFChecker, runs its checks through the Bynn API today, so
its integration lives in bynn-document-fraud and bynn-kyc-sessions.
agemin
Biometric age verification for websites and apps.
| Skill | Covers |
|---|---|
agemin | Router. Asset ID versus private key, and why the browser result is not proof. |
agemin-web-sdk | @bynn-intelligence/agemin-sdk, age gating, SEO bypass, React and Vue. |
agemin-api | Server-side confirmation, email and selfie checks, reference lookups. |
detector24
Detection models for image, video, audio, and text.
| Skill | Covers |
|---|---|
detector24 | Reading a model's input_schema and output_schema, async submission, and the rule that media must never be preprocessed. |
Credentials
Nothing here ships a credential. Each skill says which key it needs and where to get it.
| Product | Get keys at |
|---|---|
| Bynn | https://dashboard.bynn.com (agent token at /authenticate) |
| ZOREAL | https://zoreal.com: Assets for Login with ZOREAL, Settings, API keys for the Meet API |
| DecisionNode | https://decisionnode.com/console/keys |
| Agemin | https://agemin.com/app |
| Detector24 | https://detector24.ai/app |
Connect the MCP server
Installing skills does not connect the Bynn MCP server: npx skills add copies skill files
only. Connect it separately to get the Bynn tools.
claude mcp add --transport http bynn https://mcp.bynn.comThen run /mcp and sign in. The Claude Code plugin registers this URL for you, but it
stays inert until that sign-in completes. For headless use, pass a token instead:
claude mcp add --transport http bynn https://mcp.bynn.com \
--header "Authorization: Bearer $BYNN_API_TOKEN"The endpoint is the root path. Appending /mcp returns a 404.
The DecisionNode docs server needs no key or sign-in, and the decisionnode plugin
registers it for you:
claude mcp add --transport http decisionnode-docs https://decisionnode.com/mcp
``` Other clients, including
Claude Desktop, ChatGPT, Cursor, VS Code, Windsurf, and Zed, are covered in the
`bynn-mcp` skill.
## Two rules worth reading before you build
**Never preprocess media.** Do not resize, crop, re-encode, or strip metadata before
submitting an image, video, or document for fraud, tampering, or AI-generation analysis.
Those detectors read artifacts that live in the exact bytes of the original file, and
processing destroys them silently. The result comes back looking clean.
**The browser is never the verdict.** SDK callbacks run on the visitor's own machine.
Confirm every result server side before unlocking anything.
