Common questions

Is PostData safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.3.3) reached the registry 9 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

PostData MCP server

Remote MCP server for PostData, the free sensor-data store for IoT devices and the successor to dweet.io. There is no signup and no API key, for the agent or for the device.

With it, an agent can get an unused device name, write and flash the firmware, wait for the board's first reading, and give you a live chart link, without stopping to ask anyone to create an account.

Endpoint: https://api.postdata.cloud/mcp
Transport: Streamable HTTP
Authentication: none
Registry name: cloud.postdata/postdata

This repository holds the listing and setup instructions. The server itself is hosted by PostData; there is nothing to install or run.

Tools

Tool	What it does
`new_device_name`	An unused device name, with its ingest, read, live-stream and chart URLs
`publish_reading`	Store a reading, exactly like `POST /add/{device}` (one message per device every 30 s)
`get_latest`	The latest reading, when it arrived, and the chart URL
`get_history`	Per-metric min/max/mean/first/last and a downsampled series for the last N hours
`wait_for_reading`	Block (up to 50 s) until a device sends a new reading. Use it after flashing firmware
`list_recent_devices`	The 20 most recently active public devices and their payloads

publish_reading is the only tool that writes. The others are read-only.

Setup

VS Code (GitHub Copilot agent mode)

Add this to .vscode/mcp.json:

{ "servers": { "postdata": { "type": "http", "url": "https://api.postdata.cloud/mcp" } } }

Or from the command line:

code --add-mcp '{"name":"postdata","type":"http","url":"https://api.postdata.cloud/mcp"}'

Claude Code

claude mcp add --transport http postdata https://api.postdata.cloud/mcp

Claude (claude.ai, Desktop, mobile)

Go to Customize → Connectors → Add custom connector, paste https://api.postdata.cloud/mcp and choose No sign-in.

Cursor

Add this to ~/.cursor/mcp.json or .cursor/mcp.json:

{ "mcpServers": { "postdata": { "url": "https://api.postdata.cloud/mcp" } } }

OpenAI Codex

codex mcp add postdata --url https://api.postdata.cloud/mcp

Gemini CLI

gemini mcp add --transport http postdata https://api.postdata.cloud/mcp

Anything else

Add a remote (Streamable HTTP) MCP server with the URL https://api.postdata.cloud/mcp and no credentials. Per-client details for Cline, Zed, Devin and others are at https://postdata.cloud/docs#mcp.

Usage

Ask your agent things like:

Get my ESP32's DHT22 temperature and humidity onto a live chart.
I just flashed the board. Is it posting yet?
What did amber-otter-4821 read over the last 24 hours? Min, max and average.
My old dweet.io sketch stopped working. Move it to PostData.
Show me what real devices are sending, so I can copy the payload format.

A typical run: the agent calls new_device_name, writes firmware that posts JSON to the returned ingest URL, you flash the board, the agent calls wait_for_reading until the first reading lands, and then it hands you the chart URL.

Devices post over plain HTTP, HTTPS, WebSocket or MQTT-over-WebSocket. Agents that can't speak MCP can use the HTTP API described at https://postdata.cloud/llms.txt.

Things to know

Everything is public. Anyone can read any device, and anyone who knows a device's name can write to it. Don't send credentials, personal data or precise locations.
Each device can send one message every 30 seconds.
Numeric history is kept for about 92 days.
