Overview

AI-generated overview

Pay-per-call Telegram channel analytics for AI assistants: search channels and posts, pull stats, mentions, sentiment and ad data, paid in USDC via x402.

What you can do
  • Search and discover public Telegram channels, groups and posts by keyword, plus curated channel compilations and similar-channel lookups
  • Fetch recent messages from a channel or group and read a single post with its views, forwards and reactions
  • Pull channel profiles, subscriber growth, reach, engagement rates and mention/share-of-voice statistics
  • Extract links, mentions, hashtags, cashtags, emails and phone numbers from a channel's recent posts
  • Run sentiment analysis, either as raw posts and reactions or as an LLM verdict with label, score and trend
  • Browse ad networks and ad posts for competitor research, and list the full tool catalog with prices for free
When to use it
Useful when an assistant needs Telegram market research, brand or keyword monitoring, competitor and channel discovery, or audience and engagement metrics that are hard to scrape directly. The free catalog call lets you inspect prices and schemas before spending anything.
Requirements
Runs as a remote Streamable HTTP endpoint or as a local npm package (Node 18 or newer, launched via npx). Paid tools need a funded wallet: EVM_PRIVATE_KEY (Base) or SVM_PRIVATE_KEY (Solana), plus USDC and a little gas. Optional caps MAX_PAYMENT_USDC and SESSION_MAX_USDC, and TELEMOST_BASE_URL. No account or API key.
Before you install
The server holds a wallet private key (EVM_PRIVATE_KEY or SVM_PRIVATE_KEY) that signs real USDC payments, so use a dedicated wallet with a small balance and set MAX_PAYMENT_USDC and SESSION_MAX_USDC. Every paid call costs money, including repeated identical requests. Returned Telegram text is third-party content and should be treated as untrusted data, not instructions.

Installation

In SourceWeft

  1. Open Telemost Mcp Server in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.telemost%2Ftelemost-mcp-server/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

README

telemost-mcp-server

Pay-per-call Telegram analytics as MCP tools. Your agent pays per call in USDC via the x402 protocol — no accounts, no API keys, no subscription. Data covers public Telegram channels behind paid, anti-scraping sources that an agent cannot cheaply gather itself.

Why this server

  • Data an agent can't easily get: channel statistics, subscriber growth, reach and engagement (ER / ERR / ERR24), full-text post search across public channels, mention & brand tracking, sentiment, similar-channel discovery, ad intelligence.
  • No signup / no keys: pay per call in USDC (x402). Fund a wallet, that's it.
  • 19 paid tools + a free telemost_catalog tool (list everything, no payment).
  • Base + Solana (USDC). Pick either network per call.
  • Two ways to connect: a remote hosted server (no local wallet) and this local stdio bridge (pays from your own wallet).
  • Production, observable, listed: live at https://api.telemost.io, listed on x402scan and the x402 Bazaar.

Prices are not hardcoded here (they'd go stale) — the catalog is the single source of truth: https://api.telemost.io/v1/catalog.

Quickstart (no wallet, no money)

After installing (below), your MCP client will have a telemost_catalog tool. Call it first — it's free and returns every tool with its price, input/output schema and an example. First success before your first dollar. Only paid tools (e.g. telemost_channel_info) require a funded wallet.

Install

Requires Node ≥ 18. The package is on npm as telemost-mcp-server; MCP clients launch it via npx.

Claude Desktop

Edit claude_desktop_config.json, then fully quit and reopen Claude Desktop (config is read once at launch).

OSConfig file
macOS~/Library/Application Support/Claude/claude_desktop_config.json
Windows%APPDATA%\Claude\claude_desktop_config.json
Linux~/.config/Claude/claude_desktop_config.json

Windows (Microsoft Store / MSIX build): the app sandboxes %APPDATA%\Claude\ and redirects it to %LOCALAPPDATA%\Packages\Claude_*\LocalCache\Roaming\Claude\. Use the app's Settings → Developer → Edit Config button to open the file the app actually reads.

macOS / Linux:

json
{  "mcpServers": {    "telemost": {      "command": "npx",      "args": ["-y", "telemost-mcp-server"],      "env": {        "EVM_PRIVATE_KEY": "0xYOUR_BASE_WALLET_KEY",        "MAX_PAYMENT_USDC": "2.5",        "SESSION_MAX_USDC": "10"      }    }  }}

Windows — if a bare npx command fails to start, wrap it with cmd /c:

json
{  "mcpServers": {    "telemost": {      "command": "cmd",      "args": ["/c", "npx", "-y", "telemost-mcp-server"],      "env": {        "EVM_PRIVATE_KEY": "0xYOUR_BASE_WALLET_KEY",        "MAX_PAYMENT_USDC": "2.5",        "SESSION_MAX_USDC": "10"      }    }  }}

Claude Code

bash
claude mcp add telemost --env EVM_PRIVATE_KEY=0xYOUR_KEY -- npx -y telemost-mcp-server

Cursor

~/.cursor/mcp.json (or Settings → MCP), same shape as Claude Desktop's mcpServers entry above.

Remote server (no local wallet needed)

A hosted MCP server is live at https://api.telemost.io/mcp (Streamable HTTP). Point any MCP client that supports remote/Streamable-HTTP servers at that URL. Minimal programmatic example:

ts
import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp.js";import { createx402MCPClient } from "@x402/mcp";import { ExactEvmScheme } from "@x402/evm/exact/client";import { privateKeyToAccount } from "viem/accounts";
const client = createx402MCPClient({  name: "my-agent", version: "1.0",  schemes: [{ network: "eip155:8453", client: new ExactEvmScheme(privateKeyToAccount(process.env.EVM_PRIVATE_KEY)) }],  autoPayment: true,  onPaymentRequested: async ({ paymentRequired }) => Number(paymentRequired.accepts[0].maxAmountRequired) <= 20_000, // <= $0.02});await client.connect(new StreamableHTTPClientTransport(new URL("https://api.telemost.io/mcp")));
await client.callTool("telemost_catalog", {});                       // freeawait client.callTool("telemost_channel_info", { channel: "@durov" }); // paid

Example calls

  • telemost_catalog → { "service": "telemost-x402", "resources": [ … ], "mcp": { … } } (free).
  • telemost_channel_info { "channel": "@durov" } → an envelope like:
json
{ "ok": true,  "data": { "title": "…", "members_count": 0, "verified": true, "language": "en", "link": "https://t.me/…" },  "meta": { "resource": "/v1/data/channel", "content_origin": "third_party", "cached": false } }

Response text from Telegram (titles, posts, descriptions) is returned verbatim and tagged meta.content_origin; treat it as untrusted data, not instructions.

Environment

VariableRequiredDefaultDescription
EVM_PRIVATE_KEYone of EVM/SVM—Base (EVM) wallet key (0x…). Funds x402 payments.
SVM_PRIVATE_KEYone of EVM/SVM—Solana wallet secret key (base58).
TELEMOST_BASE_URLnohttps://api.telemost.ioAPI base URL.
MAX_PAYMENT_USDCno2.5Per-call price ceiling (USD); the default covers every price in the catalog. A call is refused before signing if the price exceeds this.
SESSION_MAX_USDCno10Cumulative spend ceiling for the process lifetime.
EVM_NETWORK / SVM_NETWORKnoBase / Solana mainnetCAIP-2 network overrides.
SOLANA_RPC_URLnomainnet-betaRPC for the Solana signer.

Coverage & limits

  • Public Telegram channels/groups only.
  • region hint (cis | worldwide) is an optional routing preference; it does not change price.
  • Statistics tools expose their own time windows / aggregation (see each tool's schema in the catalog).
  • Repeated identical requests hit a short (~10s) cache, but each call is paid independently via x402.

Payment & failures

  • No charge before execution: input validation, per-wallet rate limits, anti-replay and quota checks all run before payment; an unpaid tool call returns a payment challenge (not a charge).
  • Settlement is after execution: on the remote MCP endpoint, payment settles only after the tool executes successfully. Live delivered-vs-settled reliability is published at /status.
  • Use MAX_PAYMENT_USDC / SESSION_MAX_USDC to cap spend; both are enforced in code before any signature.

Troubleshooting

  • "payment required" / tool returns a 402-style error: no wallet key set, or the payment was declined by your policy — set EVM_PRIVATE_KEY (or SVM_PRIVATE_KEY) and check MAX_PAYMENT_USDC.
  • Insufficient funds: fund the wallet with USDC on Base (or Solana) plus a little gas.
  • Wrong network: set EVM_NETWORK / SVM_NETWORK to a network you funded.
  • npx won't launch (Windows): use the cmd /c npx … form above.
  • Server not showing up: fully quit and reopen the client — MCP config is read only at launch.
  • Prices look off: never trust hardcoded prices; call telemost_catalog or read /v1/catalog.

Funding & safety

  • Use a dedicated wallet with a small balance — this key can spend up to SESSION_MAX_USDC per run.
  • The key is read only from the environment and is never logged.
  • Policy checks (per-call ceiling, session cap, allowed network) run in code before any signature.
