How it works

Quick start

Requires Node.js 22.12 or later.

# Install the MCP server
npm install -g @discord-mcp/cli

# Keep the caller-owned bot token in this terminal
export DISCORD_TOKEN="Bot YOUR_DISCORD_BOT_TOKEN"

# Verify the bot, choose its real Discord server, save a non-secret profile,
# and generate a safe Codex fragment
discord-mcp setup --profile devbot --client codex

# Verify the rest of the local configuration
discord-mcp doctor --profile devbot --online

# Verify the real MCP path without changing Discord
discord-mcp smoke --profile devbot

On PowerShell, set the token before running the same setup and verification commands:

$env:DISCORD_TOKEN = "Bot YOUR_DISCORD_BOT_TOKEN"

setup supports Codex, Claude Desktop, Claude Code, Cursor, and a generic MCP client. It sends the current token only to Discord, verifies the bot identity, chooses a guild boundary, and saves a versioned local profile containing only non-secret metadata. The generated client fragment runs a pinned @discord-mcp/cli package through npx, then serve --profile devbot, so it does not depend on an absolute installation or cache path. It forwards DISCORD_TOKEN from the caller's launch environment; neither the profile nor the default Codex fragment stores the token. A profile is locked to its first verified bot ID, so --force cannot silently reassign it to another bot. Use profile list, profile show, and profile remove for lifecycle management. The older init command remains available as a stateless snippet generator. See the installation guide for non-interactive and client-specific setup.

For MCP clients that do not natively defer large tool catalogs, set MCP_TOOL_SURFACE=progressive. The model initially receives only mcp_tools_search plus read, write, and destructive dispatchers, then loads compact tool matches on demand. A single match already includes its schema; for multiple matches, search the selected tool's exact name before dispatch, or use detail: "full" when several contracts are needed together. The result chooses the dispatcher whose annotations match the selected tool's risk. MCP_CATEGORIES remains the authorization boundary; progressive mode does not bypass confirmation, dry-run, audit, or other middleware.

Set ALLOWED_GUILDS to a comma-separated list of server IDs to enforce the bot's guild boundary inside discord-mcp. Direct guild calls use a constant-time check; channel, thread, webhook, invite, and guild-sticker routes are resolved before execution and cached. Global writes and opaque interaction-token routes that cannot prove a guild are unavailable while the allowlist is active. The resolution caches are bounded to prevent untrusted ID churn from growing memory without limit. users_list_current_user_guilds remains a read-only discovery tool; seeing a guild in that result does not authorize operations against it.

To run without a global install:

npx -y @discord-mcp/cli init --client cursor

Remote OpenAI / Codex MCP

For the OpenAI Responses API or Codex, run a bearer-protected Streamable HTTP endpoint and place it behind an HTTPS reverse proxy:

export DISCORD_TOKEN="Bot YOUR_DISCORD_BOT_TOKEN"
export DISCORD_MCP_ACCESS_TOKEN="replace-with-a-long-random-secret"
discord-mcp serve --http --host 127.0.0.1 --port 3000

The endpoint is /mcp; send Authorization: Bearer <DISCORD_MCP_ACCESS_TOKEN>. It negotiates stable MCP 2026-07-28 while retaining stateless compatibility for 2025-era Streamable HTTP clients. Every authenticated client shares the deployment's caller-owned Discord bot identity, so use least-privilege Discord roles plus narrow ALLOWED_GUILDS and MCP_CATEGORIES allowlists. The OpenAI remote MCP guide covers HTTPS, Responses API tool_search/defer_loading, Codex progressive discovery, and the current OAuth boundary.

What you get

Area	Examples
Messages and channels	Send, edit, pin, search, manage threads, forums, and permissions
Moderation and safety	Bans, role changes, AutoMod rules, bulk actions, and audit-aware operations
Community operations	Members, roles, invites, onboarding, events, polls, soundboard, and voice
Application APIs	Slash commands, interactions, application emojis, webhooks, and entitlements
Agent workflows	Tool output schemas, predictable errors, migration adapters, and client config generation

Explore the complete, generated tool reference and practical recipes.

Built for production use

• Safety controls - destructive operations require explicit confirmation; guild and category allowlists constrain the bot's blast radius server-side.
• Reliable Discord access - retries, timeouts, rate-limit handling, and circuit breaking protect agent workflows from transient API failures.
• Observability - OpenTelemetry traces and metrics, structured logs, and audit events make operations inspectable.
• Typed contracts - every tool is schema-defined; public core exports, CLI flags, configuration variables, and tool metadata are regression-tested.
• Supply-chain evidence - npm releases are published from GitHub Actions with signed SLSA provenance.

Commands

Command	Purpose
discord-mcp serve	Start the local stdio MCP server (default), or serve --http for a bearer-protected Streamable HTTP endpoint.
discord-mcp setup	Verify one caller-owned bot, save a non-secret profile, and generate its client configuration.
discord-mcp activity	Show the local, privacy-safe evidence journal for setup and verification outcomes.
discord-mcp update	Check a generated Codex launcher for a newer release; apply it only with explicit --apply.
discord-mcp profile	List, inspect, or remove local non-secret bot profiles.
discord-mcp init	Generate a stateless MCP client configuration snippet.
discord-mcp doctor	Check Node.js, token format, environment, audit configuration, optional network connectivity, and a saved Codex launcher's update status.
discord-mcp smoke	Verify the MCP-to-Discord path; add --confirm-write for a self-cleaning CRUD test, or --confirm-template-lifecycle to prove Guild Template inspect/diff/sync/delete and cleanup.
discord-mcp migrate	Create a migration report from a supported Discord MCP setup.

Run discord-mcp --help or see the full CLI reference for flags and examples.

Packages

Package	Use it when
@discord-mcp/cli	You want to run Discord MCP from an AI client or terminal.
@discord-mcp/core	You are building an integration on the typed Discord MCP tool and server primitives.

The CLI runs on macOS, Linux, and Windows. Its executable is always discord-mcp.

Migrate an existing setup

discord-mcp includes migration adapters for established community projects, including PaSympa, quadslab, and discord-ops. Start with:

discord-mcp migrate --list

Then use discord-mcp migrate --from <adapter> --source <path> to generate a tool-by-tool mapping report. The migration guides explain each adapter and its limits.

Develop locally

pnpm install
pnpm build
pnpm test

The repository is a pnpm workspace. For a real Discord smoke test, set DISCORD_TOKEN and run node packages/mcp-server/dist/cli.js; the MCP Inspector is useful for verifying tools/list interactively.

Project status

discord-mcp is pre-1.0. The current public release is v0.16.5; this source tree's core exports, CLI surface, environment schema, and 201-tool registry are covered by contract tests. See the changelog and v1.0 readiness checklist before depending on an unstable surface.
