What is guildbridge CLAUDE.md?

A project guide for GuildBridge, a server that lets AI tools perform controlled Discord actions. It documents the project structure, development commands, deployment, checks, authentication, and access rules.

Use it when changing GuildBridge, especially its Discord tools, OAuth login, Cloudflare deployment, administration panel, or audit logging.

It gives coding agents the repository context they need to work consistently instead of guessing how the project is built or organized.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01065	$0.01065
Opus 5.5	$0.00426	$0.00426
Sonnet 5.5	$0.00213	$0.00213
Haiku 4.5	$0.00106	$0.00106

Security

Grade A, and why

guildbridge CLAUDE.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.

Build & Check Commands

npm run dev — Start local dev server (port 8788)
npm run deploy — Deploy to Cloudflare Workers
npm run type-check — Run tsc --noEmit (no test suite exists)

Project Overview

GuildBridge is a remote MCP server deployed on Cloudflare Workers. It exposes Discord operations (read, search, post messages) as MCP tools. Authentication is via Discord OAuth; all Discord API calls use a bot token.

Architecture

src/index.ts — MCP server definition, tool handlers, access control logic (guild + channel)
src/discord-api.ts — Discord REST API wrappers, types, and permission computation
src/discord-handler.ts — Discord OAuth flow (Hono routes)
src/utils.ts — OAuth token exchange helpers, Props type (user identity stored in auth token)
src/workers-oauth-utils.ts — CSRF/session/state management
src/cf-access.ts — Cloudflare Access JWT validation middleware
src/admin.ts — Admin panel UI + API: Allowlist tab (KV), Activity tab (D1 audit log)
src/audit.ts — Tool-call audit: dual-write to D1 + Analytics Engine

Key Design Decisions

Access control is two-layered

Guild membership — checked via the user's OAuth access token (listUserGuilds). Cached 60s.
Channel visibility — computed using Discord's permission algorithm (computePermissions). Uses bot token to fetch guild roles, member roles, and channel permission overwrites. Cached 60s per guild.

Bot token vs user token

All Discord API calls use the bot token. The user's OAuth token is only used to verify guild membership (/users/@me/guilds with Bearer auth). This means the bot must be in any guild the user wants to access.

Permission computation follows Discord's algorithm

computePermissions in discord-api.ts implements the standard Discord permission resolution:

Start with @everyone role permissions
OR in member's role permissions
Short-circuit if ADMINISTRATOR
Apply channel-level overwrites: @everyone → roles → member-specific Guild owners bypass permission checks entirely.

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.
