An AI agent writes posts and publishes via webhook
An AI agent writes content itself and publishes it to every channel.

Max The problem
An AI agent can generate posts, but getting them to Telegram, VK and Max is a separate task. Wiring three platform APIs into the agent, watching for duplicates and delivery failures — that's no longer about content, it's about infrastructure.
How Crosslybot solves it
The agent sends a ready post with a single POST to the Crosslybot webhook — from there the post goes to every configured platform. Idempotency by key protects against duplicates, retry against failures. For Claude, Cursor and Cline there's an MCP server with a publish tool.
Crosslybot lets an AI agent close the whole publishing cycle. The agent — ChatGPT, Claude or your own — generates a post and sends it with a single POST to the Crosslybot webhook, from where the content goes to Telegram, VK and Max.
Idempotency by key protects against duplicates on repeated requests, and automatic retry protects against delivery failures. For Claude, Cursor and Cline there’s an MCP server: the agent calls discover and publish tools straight from the conversation, with no separate integration.
How to set up
Create a webhook endpoint
In the Crosslybot dashboard, create an incoming webhook and attach it to a project with the targets you need.
Give the agent a token
Pass the agent the Bearer token and (optionally) the endpoint's HMAC secret.
Teach the agent to send a POST
The agent builds JSON with text, media and idempotency_key and sends it to the webhook — or calls the MCP publish tool.
Run it on a schedule
The agent writes and publishes posts on cron or on an event — with no human involvement.
What's inside
Idempotency
A repeated POST with the same idempotency_key doesn't create a duplicate — the agent can safely retry requests.
MCP for agents
The MCP server gives Claude, Cursor and Cline discover and publish tools — posting straight from the conversation with the agent.
Delivery retry
If a platform is temporarily unavailable, Crosslybot retries the publication itself — the agent doesn't need to track delivery.
Result
The AI agent closes the whole cycle — from generating the text to publishing on every channel. No manual infrastructure for platform APIs.
FAQ
Which agents are supported?
Any that can send an HTTP POST. For Claude, Cursor and Cline there's a ready MCP server — the agent calls the tools directly.
What if the agent sends one post twice?
There won't be a duplicate: when the idempotency_key matches, the repeated request is ignored.
Can I publish to specific channels?
Yes. The payload can specify targets — the post goes only to the chosen targets of the project.
What plan is needed?
Webhook IN and MCP are available on the Pro plan and above.
