MCP Server

Cryyer includes an MCP (Model Context Protocol) server that lets you review, edit, and send drafts conversationally in Claude Desktop. It also supports subscriber management.

Setup

pnpm run build   # compiles dist/mcp.js

Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "cryyer": {
      "command": "node",
      "args": ["/path/to/cryyer/dist/mcp.js"],
      "env": {
        "GITHUB_TOKEN": "ghp_...",
        "CRYYER_REPO": "owner/repo",
        "CRYYER_ROOT": "/path/to/cryyer",
        "RESEND_API_KEY": "re_...",
        "FROM_EMAIL": "updates@example.com",
        "SUBSCRIBER_STORE": "json",
        "LLM_PROVIDER": "anthropic",
        "ANTHROPIC_API_KEY": "sk-ant-..."
      }
    }
  }
}

Only GITHUB_TOKEN and CRYYER_REPO are needed for read-only tools (list_drafts, get_draft). Other env vars are needed for sending, regenerating, and subscriber management.

Tools

Tool	Description
list_drafts	List open draft issues
get_draft	Get full draft content with subscriber count
update_draft	Save revised subject + body
send_draft	Send emails, close issue, post stats
regenerate_draft	Re-gather activity + re-draft via LLM
list_products	Show configured products
list_subscribers	Show subscribers for a product (optional audience_id)
add_subscriber	Add a subscriber to a product (optional audience_id)
remove_subscriber	Unsubscribe someone from a product (optional audience_id)

Prompt

Use the review_drafts prompt for the review workflow — it walks through each pending draft and asks whether to send, edit, regenerate, or skip.

Alternative: npx

You can also run the MCP server via npx without cloning the repo:

{
  "mcpServers": {
    "cryyer": {
      "command": "npx",
      "args": ["@atriumn/cryyer-mcp"],
      "env": { ... }
    }
  }
}
