call4me blog

Read the call4me blog (https://call4.me/blog, every post as markdown in https://call4.me/llms.txt) and help me get a phone chore done with call4me.

If you don't have the call4me tools (call4me_*) yet, add the call4me MCP server first and sign me in:
   - Claude Code:  claude mcp add --scope user --transport http call4me https://call4.me/mcp  (then I run /mcp, pick call4me, and choose authenticate)
   - Codex:        codex mcp add call4me --url https://call4.me/mcp  then  codex mcp login call4me
   - Claude Desktop, claude.ai, or ChatGPT: add a custom connector with the URL https://call4.me/mcp and sign in when it asks.
   - Muse: build a custom integration to the call4me remote MCP server at https://call4.me/mcp (streamable HTTP) with the official MCP SDK. Ask me for my call4me API key (it's at https://call4.me/account) through your secure credential flow, never in chat, store it in your Secure Credentials Store, and send it as Authorization: Bearer <key>. List the tools, test call4me_get_balance, and save it as a reusable skill.
   - Grok Bot: add a custom MCP server called call4me (remote HTTPS, no headers, no auth) at my personal server URL, which I copy from https://call4.me/account. You add it from this chat; no separate approval is needed. If you offer sign-in instead, use https://call4.me/mcp and I sign in.
   - grok.com: you can't add connectors from the chat, so I do it: grok.com/connectors, New Connector, Custom, with the URL https://call4.me/mcp, then I sign in.
   - If you can't sign me in, I copy my personal server URL from https://call4.me/account and you use that instead.
   I sign in with Google or X.

Ask me what I need called for. If a post covers it, use its tips. Then call call4me_get_requirements for the category, ask me in one message for anything missing, place the call with call4me_place_call, follow it with call4me_get_call until it finishes, and tell me the result in one or two lines.
