Claude Code & CLIs

Remote MCP — API key

Point your client at our hosted MCP endpoint and authenticate with your Postproxy API key (query param or X-Postproxy-API-Key header). Best for Claude Code, terminals, and headless workflows.

Claude Code

claude mcp add --transport http postproxy \
  https://mcp.postproxy.dev/mcp?api_key=YOUR_KEY

On your machine

Local MCP — npm package

Install with Node.js 18+ and register stdio transport. Best when you want the server only on your machine or air-gapped workflows.

npm install -g postproxy-mcp
claude mcp add --transport stdio postproxy-mcp \
  --env POSTPROXY_API_KEY=your-api-key \
  --env POSTPROXY_BASE_URL=https://api.postproxy.dev/api \
  -- postproxy-mcp

Publish directly from Claude Code

Postproxy can be used as a native MCP tool inside Claude Code. Ask an agent what to publish, confirm the action, and let Postproxy handle execution and retries.

What this example shows

The agent lists available Postproxy profiles
User requests to publish a post
Postproxy publishes the post and returns a post ID
Agent exposes publish status — all from the terminal

Agents publish, reply, and engage.
Postproxy executes it reliably.

Why MCP matters for automation

Automation is moving beyond scripts and dashboards.

Modern workflows are agent-driven: LLMs reason, decide, and execute actions across systems.

MCP is the execution layer that makes this possible. Postproxy turns the full social workflow into reliable capabilities agents can call through one stable contract.

Publishing, comment replies, and DM handling sit alongside other automated, observable workflows in real systems.

What you can automate

Release updates

Publish release announcements directly from notes or changelogs without switching tools.

Pull request & deploy summaries

Turn recent changes or deployments into short, publishable updates automatically.

Research → posts

Convert research notes, articles, or ideas into concise posts while you're still thinking about them.

Writing → publish

Stay in your writing flow and publish finished text directly, without dashboards or schedulers.

Daily status updates

Turn daily logs or task summaries into consistent public or internal updates.

Idea capture → scheduled posts

Turn quick notes into scheduled posts so ideas don't die in your drafts folder.

Comment moderation & replies

List incoming comments across platforms, generate replies with AI, and post them back — all from a single agent session.

DM inbox automation

Read direct messages, route by intent, and send replies without ever opening a social app.
