Telegram Post Search & Monitoring

TG Agent

A personal Telegram monitoring toolkit — collect messages, search across channels, get keyword alerts. Built as a pet project for my own use.

Русская версия

Features

• All chat types — channels, supergroups, gigagroups, forums, public and private
• Multi-account with automatic flood-wait rotation
• 3 search modes — local DB (FTS5), direct Telegram API, AI/LLM-powered
• AI Agent — interactive chat powered by claude-agent-sdk with automatic deepagents fallback when Claude SDK is not configured; developer override is available in Settings
• All search results are cached in a local SQLite database
• Scheduled collection — incremental message fetching on a timer
• Keyword monitoring — plain text and regex, with Telegram bot notifications
• Built-in anti-spam filters — deduplication, low-uniqueness detection, cross-channel spam, subscriber ratio filters, non-Cyrillic content filter
• Task queue — background job processing with status tracking
• Web dashboard — FastAPI + Bootstrap 5, manage everything from a browser
• Security — session encryption (Fernet + PBKDF2), web panel password, HTTP Basic fallback, HMAC-signed cookies
• Docker-ready

Quick Start

Prerequisites

• Python 3.11+
• Telegram API credentials from my.telegram.org/apps

Installation

pip install .
cp .env.example .env

Edit .env:

TG_API_ID=your_api_id
TG_API_HASH=your_api_hash
WEB_PASS=your_password
SESSION_ENCRYPTION_KEY=    # encrypts account session strings in DB
LLM_API_KEY=               # optional, for AI search
AGENT_MODEL=               # optional, Claude SDK model override
AGENT_FALLBACK_MODEL=      # optional, provider:model for deepagents fallback
AGENT_FALLBACK_API_KEY=    # optional, explicit API key for deepagents fallback provider

Start the server:

python -m src.main serve

Open http://localhost:8080 in your browser and enter the WEB_PASS password.

Docker

cp .env.example .env
# fill in your credentials
docker-compose up -d

Configuration

Environment Variables (.env)

Variable	Required	Description
TG_API_ID	Yes	Telegram API ID
TG_API_HASH	Yes	Telegram API Hash
WEB_PASS	Yes	Web panel password
SESSION_ENCRYPTION_KEY	No*	Key for encrypting Telegram session strings in DB
LLM_API_KEY	No	API key for AI-powered search (deepagents)
ANTHROPIC_API_KEY	No	Anthropic API key for claude-agent-sdk only
CLAUDE_CODE_OAUTH_TOKEN	No	Claude Code auth token for claude-agent-sdk only
AGENT_MODEL	No	Override Claude SDK model for /agent
AGENT_FALLBACK_MODEL	No	provider:model for deepagents fallback in /agent
AGENT_FALLBACK_API_KEY	No	Explicit API key passed to LangChain init_chat_model(...) for fallback

* If not set, sessions are stored in plaintext. If the DB already contains encrypted sessions (enc:v*), startup fails until this key is provided.

config.yaml

Supports ${ENV_VAR} substitution. Empty env vars are dropped (defaults apply).

Section	Description
telegram	API credentials (api_id, api_hash)
web	Host, port, password (default: 0.0.0.0:8080)
scheduler	Collection interval, delays, limits, max flood wait
notifications	admin_chat_id for keyword match alerts
database	SQLite path (default: data/tg_search.db)
llm	LLM provider, model, API key for AI search (deepagents)
agent	Claude model override and deepagents fallback settings for /agent
security	Session encryption settings

Agent backend rules

• /agent uses claude-agent-sdk when ANTHROPIC_API_KEY or CLAUDE_CODE_OAUTH_TOKEN is configured.
• If Claude SDK is not configured, /agent falls back to deepagents when AGENT_FALLBACK_MODEL is set.
• ANTHROPIC_API_KEY and CLAUDE_CODE_OAUTH_TOKEN are never reused by deepagents.
• Developer override for forcing claude-agent-sdk or deepagents lives on the Settings page and applies only when developer mode is enabled.

telethon-cli

telethon-cli is installed with the project and reuses the same TG_API_ID and TG_API_HASH values from .env.

Optional CLI-only overrides:

• TG_SESSION sets a custom Telethon session path or name.
• TG_PASSWORD supplies the Telegram 2FA password for non-interactive runs.

Legacy TELETHON_* environment variable names are still accepted by telethon-cli for compatibility, but this project standardizes on TG_*.

Development

# Install dev dependencies
pip install -e ".[dev]"

# Run parallel-safe tests (all available CPUs minus one worker)
pytest tests/ -v -m "not aiosqlite_serial" -n auto

# Run aiosqlite-backed tests serially
pytest tests/ -v -m aiosqlite_serial

# Run a single test
pytest tests/test_web.py::test_health_endpoint -v

# Benchmark serial vs safe mixed-mode suite execution
python -m src.main test benchmark

# Lint
