@seizn/author-mcp-server

MCP server exposing Seizn Author canon recall, conflict check, semantic search, timeline, and relationship graph tools to any MCP-compatible AI agent (Claude Desktop, Claude Code, Cursor, Cline, Continue, Zed, etc.).

Bring Seizn canon into the AI tool you already use. No new editor required.

What it does

When connected, your AI agent gains six tools:

All tools call the Seizn Author REST API (/api/v1/*) with your Bearer token.

Setup

1. Get a Seizn API key

Generate one at https://seizn.com/dashboard/account/api-keys (Free tier: 100 calls/day, BYOK required).

2. Install (npm)

npm install -g @seizn/author-mcp-server

Or use npx:

npx @seizn/author-mcp-server

3. Wire into your MCP client

Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "seizn-author": {
      "command": "npx",
      "args": ["-y", "@seizn/author-mcp-server"],
      "env": {
        "SEIZN_API_KEY": "sk_seizn_..."
      }
    }
  }
}

Claude Code

claude mcp add seizn-author -e SEIZN_API_KEY=sk_seizn_... -- npx -y @seizn/author-mcp-server

Cursor / Cline / Continue

See your client's MCP server documentation. The package supports:

• stdio (default for desktop clients)
• streamable-http (for hosted scenarios)
• SSE (legacy)

Configuration

Usage examples

In your AI chat:

'Recall everything Seizn knows about Seoyun in project ch7-draft.' → invokes seizn_author_recall with name=Seoyun

'Check this scene for canon conflicts: ...' → invokes seizn_author_check with the pasted text

'Show me the timeline from Ch.5 to Ch.7.' → invokes seizn_author_timeline with from=ch5, to=ch7

The AI decides when to call each tool based on the conversation. You don't have to remember tool names.

Pricing

Track 2 plan covers Track 2 surface (API + MCP) only. Seizn Author has separate plans for the web dashboard (Track 1, KRW) and the Tauri desktop app (Track 3, KRW). One Stripe customer holds multiple subscriptions, billed independently. See https://seizn.com/pricing for cross-track upsell details.

No subscription required for AI inference. Tools split into two groups:

The Seizn subscription covers the canon backend and recall infrastructure. The two AI-enhanced tools (check, timeline) require either your own LLM key (BYOK, any tier) or Studio Managed ($299/mo) which includes 500 Opus calls.

Your host AI agent's LLM is separate. Whether you use Claude Pro/Max subscription via Claude Code/Desktop, Cursor Pro, or BYOK in Cline/Continue — the host handles its own LLM cost. Seizn doesn't double-charge.

See https://seizn.com/pricing for full details.

Versioning

While the package is on 0.x.y we may ship breaking changes on minor bumps (0.2.0 etc.) — we'll call them out clearly in CHANGELOG.md. Once we tag 1.0.0, strict semver applies: major = breaking, minor = additive, patch = fix-only.

Each release is published with a matching GitHub tag (v0.1.0, …) and a CHANGELOG.md entry.
