Built by Humans for Agents
Claude, ChatGPT, Grok and Codex read and write your workspace over MCP. You choose the workspaces and the permissions on the consent screen, and you can revoke them at any time.
MCP server URL
https://api.actvox.com/mcpModel Context Protocol over Streamable HTTP with OAuth. There is no key to paste: your client opens the ActVox consent screen in your browser.
No ActVox account yet? Signing in from your agent creates one, with a workspace.
Connect
One prompt
Copy the prompt for your agent and paste it into a chat with it. Claude Code, Codex, Hermes and OpenClaw connect themselves; Claude, ChatGPT and Grok walk you through their settings. You only sign in and approve in your browser, and no key or code ever goes into the chat.
Connect your agent
Or connect it by hand:
claude.ai → Customize → Connectors → Add custom connector. Name it ActVox and paste the MCP server URL.
Authentication: Sign in now. Keep “Use Claude's published identity”: no client ID, no secret.
In a chat, open + → Connectors and switch ActVox on.
The fastest way: ActVox is in the ChatGPT plugin directory. Add it, then sign in to ActVox when ChatGPT asks.
Add to ChatGPTOr add it by hand
ChatGPT → Settings → Security and login → turn on Developer mode.
chatgpt.com/plugins → + → name the plugin, choose the public endpoint and paste the MCP server URL.
Authentication: OAuth. Leave the client ID and secret empty; you sign in on first use.
grok.com → Connectors → New Connector → Custom.
Paste the MCP server URL. Grok registers itself, so no client ID is needed.
In a chat, enable the ActVox connector from the connectors menu.
Add the server in your terminal. Codex opens the ActVox consent screen in your browser right away:
codex mcp add actvox --url https://api.actvox.com/mcpIf that sign-in did not finish, run:
codex mcp login actvoxAsk Codex to call the capabilities tool before its first write.
Gemini, Gemini CLI, Antigravity, Kimi Code, Muse, Cursor and the ActVox CLI have their own setup on the Connectors page of your workspace.
Open ConnectorsTry this first
Once your agent is connected, paste this. Saving the page needs write, a separate choice on the consent screen.
Use ActVox. Call capabilities and tell me what you can do in my workspace. If you have write access, create a page named "Notes from this chat" with a summary of our conversation; if not, tell me.Agent won't connect? See the connection help
Permissions
Read is always included. Write, run, share and publish are separate choices on the consent screen, and publishing is never granted together with write. Pause or revoke a connection at any time under Connectors in the app.
Pricing
Creating pages and databases uses none of your usage on every plan. Usage pays only for ActVox's own generation, such as reports, images and video.
