# Telegram bot templates + MCP server for AI bot development
Ready-to-use **Telegram bot templates** and an **MCP server** — build, edit, and deploy Telegram bots from Claude Code, Codex, Cursor, or any MCP-capable AI agent. No SDK boilerplate: describe the bot, and your agent assembles the flow.
[FlowCastle](https://flowcastle.ai) is a visual workflow builder for Telegram bots and web chat: flows, triggers, conditions, AI steps, payments (Stripe / YooKassa / Telegram Stars), broadcasts, drip sequences, and integrations (Gmail, Google Sheets, Notion, OpenAI, …) — with a REST API and an MCP server, so bot development works straight from your AI coding agent. Every block an agent creates through MCP is the same block you can drag, wire, and edit visually.
This repo is for developers. It contains:
| Path | What it is |
|------|-----------|
| [`templates/`](templates/) | 23 production bot templates as JSON — the same source that powers the [template gallery](https://flowcastle.ai/templates) and the MCP `get_flow_example` tool |
| [`mcp/`](mcp/) | MCP server reference: endpoint, auth, all 16 tools, and a snapshot of the flow-action schema used by `apply_actions` |
## Build a bot from your AI agent (MCP)
FlowCastle exposes an MCP server over **Streamable HTTP**:
```
POST https://api.flowcastle.ai/api/mcp
Authorization: Bearer <your-application-api-key> # starts with app_
```
Get a key: [sign up](https://dashboard.flowcastle.ai/register) → create an application → **API** page → **MCP** tab.
**Claude Code**
```bash
export FLOWCASTLE_MCP_TOKEN='<your-application-api-key>'
claude mcp add --transport http flowcastle https://api.flowcastle.ai/api/mcp \
--header "Authorization: Bearer $FLOWCASTLE_MCP_TOKEN"
```
**Codex**
```bash
codex mcp add flowcastle \
--url https://api.flowcastle.ai/api/mcp \
--bearer-token-env-var FLOWCASTLE_MCP_TOKEN
```
**Cursor / any MCP client (JSON config)**
```json
{
"mcpServers": {
"flowcastle": {
"type": "http",
"url": "https://api.flowcastle.ai/api/mcp",
"headers": {
"Authorization": "Bearer <your-application-api-key>"
}
}
}
}
```
Then just ask your agent things like:
> *"Look at my FlowCastle workspace and add a lead-qualification flow: greet on /start, ask three button questions, save answers to contact variables, and notify me."*
The agent reads your workspace with `get_workspace_summary` / `get_flow_context`, drafts a batch of flow-builder actions, checks it with `validate_actions`, and applies it with `apply_actions`. See [`mcp/README.md`](mcp/README.md) for the full tool reference.
## Templates
Each JSON file in [`templates/`](templates/) is a complete bot: metadata (title, summary, use-cases, suggested variables, required modules) plus a `schemaExample.actions` array — an ordered batch of `create_flow` / `create_block` / `create_link` / `create_variable` operations in the exact format `apply_actions` accepts.
Three ways to use them:
1. **One-click install** from the gallery: [flowcastle.ai/templates](https://flowcastle.ai/templates)
2. **Via MCP** — ask your agent to `search_flow_examples` / `get_flow_example` and apply one (optionally customized) to your workspace
3. **As reference** — study how real flows wire triggers, conditions, wait-for-reply steps, payments, and AI blocks
Full index and format description: [`templates/README.md`](templates/README.md).
## REST Public API
Application-scoped REST API for contacts, contact variables, goal events, flow sends, and broadcasts:
- Base URL: `https://api.flowcastle.ai/api/public/v1`
- Interactive docs (Swagger): https://api.flowcastle.ai/api/public/docs
- OpenAPI spec: https://api.flowcastle.ai/api/public/openapi.json
Auth uses the same `app_…` application key (`Authorization: Bearer` or `X-API-Key`).

## Contributing
Found a bug in a template, or built a flow worth sharing? Open an issue or PR — templates are plain JSON, and `validate_actions` (via MCP) will tell you if a batch is well-formed.
