AOJ Workbench
One private MCP endpoint for your knowledge-work toolkits.
Give an AI agent one URL and it can work through AOJ Workbench.

Remote Only
AOJ Workbench is a private remote HTTP MCP server hosted on Cloudflare Workers.
The supported client experience is:
https://your-worker.workers.dev/mcp
There is no supported local stdio server, local HTTP server, Docker runtime, or local bootstrap flow for MCP clients. Clients connect to the remote /mcp endpoint by URL.
Legacy local commands and Docker instructions from older versions are not part of the supported runtime model.
Why This Exists
AI agents can draft plans, reason over code, and summarize documents, but daily work spans many tools:
- Gmail and Google Workspace
- Outlook
- Notion
- Stripe
- YouTube
- other selected Composio-supported toolkits
AOJ Workbench gives agents one MCP endpoint. The target provider layer is the Composio SDK with managed auth. The current direct Google implementation is legacy migration scaffolding until provider replacement slices remove it.
Quick Start
1. Get The Endpoint
Use the deployed Worker URL:
https://your-worker.workers.dev/mcp
The Worker must already be deployed and configured with its MCP bearer token and the required Composio runtime secrets. Provider accounts are connected in Composio for the configured AOJ Workbench user.
2. Connect Claude Code
Use a descriptive MCP server name so agents understand the full surface area:
claude mcp add --scope user --transport http aoj-workbench https://your-worker.workers.dev/mcp
If bearer auth is enabled for the Worker, configure the same bearer token expected by the server.
3. Connect Codex
export AOJ_WORKBENCH_MCP_TOKEN="replace-with-worker-token"
codex mcp add aoj-workbench \
--url https://your-worker.workers.dev/mcp \
--bearer-token-env-var AOJ_WORKBENCH_MCP_TOKEN
Start a fresh Codex session after changing MCP config.
Provider Model
AOJ Workbench keeps one public MCP connector. Behind that connector, Composio SDK sessions discover and execute selected provider toolkit actions.
The direct Google Workspace modules that remain in the repo are legacy migration scaffolding. The supported runtime routes provider discovery and execution through the Composio native provider layer. Current AOJ Workbench capabilities include:
| Service | Operations | Highlights |
|---|---|---|
| Drive | 7 | Search, enhanced search, read, create, update, batch operations |
| Sheets | 12 | Read/write cells, formulas, formatting, conditional formatting, freeze, column width |
| Gmail | 30+ | List, search, read, draft, send emails, manage labels, and work with attachments |
| Calendar | 9 | Full CRUD, natural language quickAdd, free/busy checks |
| Docs | 5 | Create, insert text, replace, rich text styling, insert tables |
| Forms | 4 | Create forms, add questions, read responses |
| 70+ total |
Live Forms execution requires an active Google Forms-capable connected account in Composio for AOJ_WORKBENCH_USER_ID.
Tools
v4 exposes two MCP tools:
| Tool | Purpose |
|---|---|
search |
Discover provider/toolkit capabilities, schemas, auth status, and execution guidance |
execute |
Run a selected provider toolkit operation |
This keeps the MCP tool list small while avoiding separate client connectors for every provider.
Example direct operation call:
{
"tool": "execute",
"args": {
"service": "gmail",
"operation": "sendMessage",
"args": {
"to": "team@example.com",
"subject": "Q1 report ready",
"body": "The Q1 report is ready for review."
}
}
}
Example discovery call:
{
"tool": "search",
"args": {
"service": "sheets",
"operation": "updateCells"
}
}

Provider toolkits
Persistent state belongs in Cloudflare services, primarily Workers KV. The user-facing MCP runtime is the Worker URL.
Security
- MCP clients authenticate to the Worker with static bearer auth when configured.
- Provider authorization belongs to Composio managed auth in the target architecture.
- This server is not an OAuth authorization server for MCP clients.
- Do not point MCP client auth metadata at provider OAuth.
Development
Development commands are for contributors changing the Worker implementation, not for running the MCP server locally as a client dependency.
npm test
npm run type-check
npm run build:worker
npm run deploy:worker
Do not add local stdio, local HTTP, or Docker connection instructions back to user-facing docs.
Roadmap
- [ ] Composio native provider — discovery, auth status, schema lookup, execution
- [ ] Google provider replacement — migrate current direct Google capabilities behind Composio
- [ ] Notion toolkit — selected private-workbench workflows
- [ ] Stripe toolkit — selected private-workbench workflows
- [ ] YouTube toolkit — selected private-workbench workflows
- [ ] Outlook toolkit — selected private-workbench workflows
- [x] Cloudflare Workers — remote HTTP MCP runtime
