NanoClaw

NanoClaw is an open-source assistant that runs each agent in its own Docker container on your machine, built on the Claude Agent SDK. You talk to it over Slack, Telegram, Discord, WhatsApp, iMessage and other chat apps. Add PostQueen’s MCP server to an agent group and you can ask it, from any of those apps, to write your posts for PostQueen to schedule, and check how they did.

A sample NanoClaw chat on a phone with PostQueen connected: a request for posts, the PostQueen tools it used, and the reply

Before you start

Plans: NanoClaw is free and open source (MIT). You run it yourself with an Anthropic API key or a Claude subscription.
Platforms: your own macOS or Linux machine, or Windows through WSL2, with Docker. The installer adds Node 22, pnpm and Docker if they are missing.
NanoClaw, installed, with at least one agent group. Follow NanoClaw’s install guide.
A PostQueen API key. A workspace admin copies it from Connections.

Where the API key is: in the app, open Connections > API key. Only a workspace Admin or Super Admin can reveal or rotate it; other members see it masked. A workspace has one key, and each agent card on Connections shows your MCP address with the key already filled in.

Connect NanoClaw

NanoClaw keeps keys in its OneCLI vault and adds them to the agent’s requests, so the agent itself never sees your key. Run these on the machine that runs NanoClaw.

Save the key in the vault

onecli secrets create --name PostQueen --type generic \
  --value YOUR_API_KEY --host-pattern api.postqueen.ai \
  --header-name Authorization --value-format "Bearer {value}"

Find your agent group

ncl groups list

Check that the group's agent can use the key

onecli agents list

Each agent group has a OneCLI agent whose identifier is the group’s id; it appears once the group has run. On the OneCLI version NanoClaw installs, agents use secret mode all and pick up the PostQueen secret by its host, so there is nothing to grant. If the agent shows secretMode selective, add the secret (its id is in onecli secrets list) as NanoClaw’s Credentials page shows. On OneCLI with agent grants (server 1.44 or later, CLI 2.9 or later):

onecli agents grants attach-secret --id <agent-id> --secret-id <secret-id>

Add PostQueen and restart the group

Use the group’s id in place of YOUR_GROUP_ID. The address has no key in it:

ncl groups config add-mcp-server --id YOUR_GROUP_ID \
  --name postqueen --url https://api.postqueen.ai/mcp
ncl groups restart --id YOUR_GROUP_ID

Check that it works

Message the agent in one of your chat apps: “List my PostQueen channels.” It answers with the channels you connected in PostQueen. If the tools do not load, see Troubleshooting.

Good to know

Last resort if the tools still do not load: add the server with the key as a header instead, then restart the group. This goes against NanoClaw’s advice: --headers is meant for non-secret headers, and real credentials belong in the vault.
ncl groups config add-mcp-server --id YOUR_GROUP_ID \ --name postqueen --url https://api.postqueen.ai/mcp \ --headers '{"Authorization":"Bearer YOUR_API_KEY"}'
The key then sits in the group’s config, where the agent can read it.
Do not use the address with the key in it. The key would sit in the group’s config. Keep it in the OneCLI vault.
Use the MCP server, not the PostQueen CLI or skill. NanoClaw keeps keys out of its containers: it rejects credential values in a container’s environment. The MCP server gets the key from the vault.
The agent can add the server itself with its add_mcp_server tool, which needs admin approval in NanoClaw. The key still has to go into the vault first.
Ask for drafts when you want to check first. A draft waits on your PostQueen calendar, and nothing publishes until you schedule it.
What it cannot do over MCP: change a post’s text or time. Do that on the calendar in the app. The MCP tools lists what it can do.

The key in the OneCLI vault	`https://api.postqueen.ai/mcp`	From NanoClaw’s docs. The route above
The key as a header in the group’s config	`https://api.postqueen.ai/mcp`	Against NanoClaw’s advice. The last resort above

Try this first

List my PostQueen channels. Then draft two short Bluesky posts about Saturday's event and save them in PostQueen as drafts for Friday at 10am.

The drafts appear on your PostQueen calendar, ready for you to check and schedule. Prompts to try has more.

Run it on a schedule

Ask your agent in chat for a recurring task, such as the one below. It creates the task with ncl tasks create, and ncl tasks list shows every series.

Every weekday at 9am, save one post idea from my notes as a PostQueen draft.

Troubleshooting

Symptom	Fix
PostQueen tools do not load	Check the secret and the agent as in the next row, then restart the group with `ncl groups restart`. The header in Good to know is a last resort.
PostQueen answers `Missing Authorization header`	The vault did not add the key. Check that the secret’s host pattern is `api.postqueen.ai` (`onecli secrets list`) and the agent’s secret mode (`onecli agents list`). An agent in `selective` mode needs the secret, as in Connect NanoClaw.
You put the key in the address	The key would sit in the group’s config. Save it in the OneCLI vault and use `https://api.postqueen.ai/mcp`.
NanoClaw refuses `POSTQUEEN_API_KEY` in a container	It rejects credential values in a container’s environment. Keep the key in the OneCLI vault and use the MCP server.
The key is refused	Copy it again from Connections > API key. Only a workspace Admin or Super Admin can reveal it.
You followed an OpenClaw guide	OpenClaw is a different app with its own setup. See OpenClaw.

More fixes are on Troubleshooting agents. To pick a chat app, see Chat channels.

Is it the same as OpenClaw?

No. The names are close, but they are different apps with different setups:

Product	What it is	How it connects
NanoClaw (this page)	An assistant that runs each agent in its own container	PostQueen’s MCP server, with the key in its vault
OpenClaw	A personal agent with an always-on gateway to your chat apps	The PostQueen CLI and skill
