# Build with AI

> Give your coding agent the Byzantine docs and integration skills.

Integrate Byzantine faster with your coding agent. Pick what you need; they work well together.

> [card] [Docs MCP](#docs-mcp-server)
>
> Your agent searches these docs. Read-only.

> [card] [Agent skills](#agent-skills)
>
> Step-by-step playbooks and helpers, checked against the API.

> [card] [Plain-text docs](#plain-text-docs)
>
> Any page as markdown, for pasting into a chat.

## Quick start

**1. Install the skills**

```bash theme={null}
npx skills add Byzantine-Finance/agent-skills
```

**2. Add the docs MCP server**

```bash theme={null}
claude mcp add --transport http byzantine-docs https://docs.byzantine.fi/mcp
```

**3. Ask your agent**

> "Integrate Byzantine in my app. Start with the sandbox: create an individual account, then a deposit."

Your agent follows the [Integration guide](https://docs.byzantine.fi/api-reference/integration-guide.md) and the skills.

## Docs MCP server

`https://docs.byzantine.fi/mcp` lets your agent search these docs. It can look things up; it cannot create accounts or move funds.

## Agent skills

The [Byzantine agent skills](https://github.com/Byzantine-Finance/agent-skills) teach Claude Code, Cursor, Codex, GitHub Copilot, Gemini CLI, Windsurf and other agents how Byzantine works and how to integrate it.

> [card] Onboarding
>
> Individual KYC, company KYB, associated persons, passkeys.

> [card] Request signing
>
> The signing contract, a request helper and a 401 diagnostic.

> [card] Money movement
>
> Passkey-approved deposits and withdrawals, statuses.

> [card] Webhooks
>
> Signature verification, events, replay.

> [tab] Any agent
>
> ```bash theme={null}
> npx skills add Byzantine-Finance/agent-skills
> ```

> [tab] Claude Code plugin
>
> Skills and docs MCP server together:
>
> ```text theme={null}
> /plugin marketplace add Byzantine-Finance/agent-skills
> /plugin install byzantine@byzantine-agent-skills
> ```

## Plain-text docs

Append `.md` to any page URL to get it as markdown. The full index is at [`/llms.txt`](https://docs.byzantine.fi/llms.txt).

## Safe defaults

> [card] Sandbox first
>
> Build in the [sandbox](https://docs.byzantine.fi/api-reference/sandbox.md). The bundled scripts only call the sandbox, never production.

> [card] Keep keys out of chats
>
> If a private key was pasted into a conversation, revoke it in the [integrator dashboard](https://integrator.byzantine.fi) (Settings → API keys) and create a new one.

> [card] Read-only keys for reporting
>
> Use a `read_only` key for dashboards, reporting and support tools.

> [card] Funds stay under user control
>
> Your agent cannot move funds on its own: every deposit and withdrawal needs the user's passkey. See the [Integration guide](https://docs.byzantine.fi/api-reference/integration-guide.md).
