Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

discord-mcp GEMINI.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project Overview

discord-mcp is a Model Context Protocol (MCP) server built with Bun and TypeScript that exposes a wide range of Discord API actions as tools. It uses Seyfert as the underlying Discord client library and Zod for robust schema validation.

Key Features

  • Comprehensive Discord Tools: Supports guild management, member moderation, message operations, channel/role configuration, audit logs, webhooks, scheduled events, and more.
  • Streamable HTTP Transport: Implements the MCP HTTP transport with ephemeral session management.
  • Security & Safety:
    • DISCORD_GUILD_ALLOWLIST: Restricts operations to specific guilds.
    • DISCORD_DRY_RUN: Prevents mutations while still validating logic.
    • Confirmation Protocol: Destructive actions require confirm: true in tool arguments.
  • Session Management: Sessions have a 60-minute idle timeout and are uniquely identified by the mcp-session-id header.

Building and Running

The project uses Bun as its primary runtime and package manager.

Core Commands

  • bun install: Install all dependencies.
  • bun run start: Start the MCP server.
  • bun run dev: Start the server in watch mode for development.
  • bun run check: Run TypeScript type-checking (no emit).
  • bun run build: Compile TypeScript to the dist/ directory.
  • bun test: Run all tests using the Bun test runner.
  • bun test <path/to/test>: Run a specific test file.

Environment Configuration

The server requires a .env file with the following minimum variables:

  • DISCORD_TOKEN: Discord Bot Token.
  • DISCORD_APPLICATION_ID: Discord Application ID.
  • MCP_HTTP_PORT: Port for the MCP server (default: 3456).

Architecture & Conventions

Directory Structure

  • src/index.ts: Entry point for the server.
  • src/config/: Environment and application configuration.
  • src/discord/: Domain-specific service classes (e.g., members.ts, messages.ts).
    • All services MUST extend DiscordBaseService from src/discord/base.ts.
  • src/mcp/: MCP-specific logic.
    • server.ts: HTTP transport and session lifecycle.
    • schemas/: Zod schemas for tool input validation.
    • tools/register.ts: Central registry for mapping services to MCP tools.
  • src/lib/: Utility libraries (logging, error handling).
  • src/types/: Shared TypeScript definitions.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
