Enables LLM agents and tools to send messages to Slack channels and direct messages through the Model Context Protocol (MCP) transport layer. Implements MCP resource and tool schemas that map Slack API message endpoints to standardized function-calling interfaces, allowing Claude and other MCP-compatible LLMs to compose and dispatch messages without direct API credential handling.
Unique: Wraps Slack Web API message endpoints as MCP tools with schema-based function calling, allowing LLMs to invoke Slack operations through standardized MCP resource definitions rather than direct API calls or custom prompt engineering
vs alternatives: Provides tighter LLM-Slack integration than generic Slack API wrappers because it uses MCP's typed tool schema to give Claude native understanding of Slack operations without requiring API key exposure in prompts
Exposes Slack channels, conversation history, and metadata as MCP resources that LLM agents can query and reference. Implements MCP resource URIs (e.g., slack://channel/C123) that map to Slack API list and history endpoints, enabling agents to discover channels, read recent messages, and extract context without manual API orchestration.
Unique: Models Slack channels and messages as MCP resources with URI-based addressing, allowing LLMs to reference and query Slack data through the same resource abstraction layer used for files and documents, rather than treating Slack as a separate API silo
vs alternatives: Integrates Slack context retrieval into the MCP resource model, giving LLMs native ability to reference Slack conversations alongside other knowledge sources without custom prompt engineering or separate API client logic
Provides MCP tools to query Slack workspace users, their profiles, and workspace metadata (name, plan, member count). Implements calls to Slack's users.list, users.info, and team.info endpoints wrapped as MCP function tools, enabling agents to resolve user mentions, check user status, and understand workspace context without direct API calls.
Unique: Exposes Slack user and workspace metadata as MCP tools with structured output schemas, allowing LLMs to query user profiles and workspace context as first-class operations rather than requiring agents to parse raw API responses or maintain user caches
vs alternatives: Provides structured, schema-validated access to Slack user and workspace data through MCP, reducing the need for agents to handle API pagination, error cases, or data transformation logic manually
Enables LLM agents to add, remove, and list emoji reactions on Slack messages through MCP tools. Wraps Slack's reactions.add, reactions.remove, and reactions.get endpoints as typed function calls, allowing agents to express sentiment, acknowledge messages, or trigger workflows based on emoji reactions without direct API credential exposure.
Unique: Models emoji reactions as MCP tools with explicit add/remove/list operations, treating reactions as a first-class interaction mechanism rather than a side effect, enabling agents to use reactions as lightweight workflow signals or acknowledgment patterns
vs alternatives: Provides structured emoji reaction management through MCP, avoiding the need for agents to compose raw Slack API calls or manage reaction state manually, and enabling reaction-based workflows without custom prompt engineering
Allows LLM agents to post replies to message threads and retrieve thread context through MCP tools. Implements thread_ts parameter handling in message send operations and thread history retrieval, enabling agents to participate in conversations, maintain threaded discussions, and read full thread context without breaking conversation flow.
Unique: Treats Slack threads as first-class conversation containers in MCP, with explicit tools for thread reply posting and history retrieval, enabling agents to participate in threaded discussions while maintaining conversation context and organization
vs alternatives: Provides native thread support in MCP tooling, allowing agents to understand and participate in threaded conversations without custom logic to parse thread_ts or manage thread context manually
Implements the MCP server initialization, configuration, and transport layer for Slack integration. Handles stdio-based MCP protocol communication, tool and resource schema registration, and Slack API credential management through environment variables or configuration files. Manages the server lifecycle from startup through request handling and graceful shutdown.
Unique: Implements a complete MCP server wrapper around Slack API operations, handling protocol-level concerns (schema registration, request routing, error handling) so that Slack operations are exposed as native MCP tools without requiring clients to manage API details
vs alternatives: Provides a self-contained MCP server that abstracts away Slack API credential and protocol complexity, allowing MCP clients to interact with Slack through standardized tool schemas rather than managing API clients or credentials directly
Crawls 11+ heterogeneous platforms (Zhihu, Weibo, Bilibili, Twitter, Reddit, HackerNews, etc.) and RSS feeds using platform-specific scrapers, normalizes disparate data schemas into a unified NewsItem model, and deduplicates content across sources using fuzzy title matching and URL canonicalization. The system maintains platform-specific metadata (rank, heat value, engagement metrics) while presenting a single normalized feed, enabling cross-platform trend detection that would be invisible within individual platform silos.
Unique: Implements platform-specific crawler modules with unified NewsItem schema and fuzzy deduplication across 11+ heterogeneous sources (Chinese + international), rather than relying on single-platform APIs or generic RSS parsing. Maintains platform-specific metadata (rank × 0.6 + frequency × 0.3 + platform hot value × 0.1) for weighted hotspot scoring.
vs alternatives: Covers more platforms (especially Chinese social media) with deeper metadata extraction than generic RSS aggregators, and provides unified deduplication across sources unlike single-platform monitoring tools.
Implements a multi-stage filtering pipeline that matches news items against user-defined keywords using regex patterns, required word lists, and excluded word lists. The system applies frequency-based scoring (keyword occurrence count) combined with platform hotspot weights to rank filtered results. Configuration is stored in frequency_words.txt with support for regex patterns, AND/OR/NOT boolean operators, and per-keyword weighting. Filtering occurs at collection time (reducing storage) and again at report generation time (enabling dynamic reconfiguration without re-crawling).
Unique: Combines regex pattern matching with frequency-based scoring and platform hotspot weighting (rank × 0.6 + frequency × 0.3 + platform hot value × 0.1) in a two-stage pipeline (collection-time and report-time filtering). Supports dynamic reconfiguration without re-crawling by applying filters at report generation.
TrendRadar scores higher at 58/100 vs @sigmacomputing/slack-mcp-server at 29/100.

Search the match graph →© 2026 Unfragile. Stronger through disorder.
vs alternatives: More flexible than simple keyword matching (supports regex and boolean logic) and more efficient than semantic filtering (no LLM overhead), making it suitable for real-time filtering at scale.
Detects newly emerged topics by comparing current crawl results against historical data stored in the system. Topics are marked as 🆕 (new) if they appear for the first time in the current crawl or if their hotspot rank increased significantly compared to previous crawls. The system tracks topic emergence velocity (how quickly a topic rises in rankings) and flags topics with unusual acceleration. New topic detection is performed at report generation time, enabling dynamic detection without re-crawling. The system maintains a historical hotspot index for comparison.
Unique: Detects new topics by comparing current hotspot rankings against historical data, marking topics with significant rank increases as 🆕. Tracks emergence velocity to distinguish breaking news from sustained trends.
vs alternatives: More efficient than semantic similarity detection (no LLM overhead) and more accurate than simple first-appearance detection (accounts for re-emerging topics), but requires historical baseline data.
Provides a web-based UI for editing TrendRadar configuration files (config.yaml, frequency_words.txt, timeline.yaml) with real-time validation and preview. The editor supports: (1) syntax highlighting for YAML and regex, (2) validation of keyword patterns (regex compilation check), (3) preview of filtered results based on current keyword configuration, (4) drag-and-drop channel configuration, (5) schedule preview (shows next 10 execution times). Changes are validated before saving, preventing configuration errors. The editor is optional; users can edit config files directly.
Unique: Provides web-based configuration editor with real-time validation, regex preview, and schedule visualization. Enables non-technical users to configure TrendRadar without editing YAML files.
vs alternatives: More user-friendly than manual YAML editing and provides validation feedback, but adds operational complexity compared to file-based configuration.
Integrates LiteLLM to provide vendor-agnostic AI analysis and summarization of filtered news items. Users configure their preferred LLM provider (OpenAI, Anthropic, Ollama, local models, etc.) once in config.yaml, and the system automatically routes analysis requests to that provider. The AI analysis capability includes: (1) automated summarization of long articles into key points, (2) sentiment analysis (positive/negative/neutral), (3) trend prediction based on historical patterns, and (4) custom analysis prompts. Analysis results are cached to avoid redundant API calls and can be pushed directly to notification channels.
Unique: Uses LiteLLM abstraction layer to support any LLM provider (OpenAI, Anthropic, Ollama, local models) with single configuration, enabling provider switching without code changes. Caches analysis results to reduce redundant API calls and costs.
vs alternatives: More flexible than hardcoded OpenAI integration (supports any LiteLLM provider) and cheaper than dedicated sentiment analysis APIs (can use local models), but slower than rule-based sentiment analysis.
Leverages LiteLLM to translate news content from source languages (primarily Chinese) to target languages (English, etc.) on-demand. The system detects source language automatically (via langdetect or similar), caches translations to avoid re-translating identical content, and batches translation requests to reduce API calls. Translations are stored alongside original content, enabling bilingual reports and multi-language notification delivery. Translation can be triggered at collection time (all news) or report time (only filtered news).
Unique: Implements provider-agnostic translation via LiteLLM with automatic language detection, content-based caching, and batch request optimization. Stores translations alongside originals for bilingual report generation.
vs alternatives: More flexible than dedicated translation APIs (supports any LiteLLM provider) and cheaper than commercial translation services when using local models, but slower than specialized translation APIs.
Implements a notification abstraction layer supporting 9+ delivery channels (WeChat, WeWork, Feishu, Telegram, Email, ntfy, Bark, Slack, etc.). Each channel has a provider-specific formatter that converts normalized news items into channel-appropriate messages (e.g., WeChat card format, Telegram markdown, email HTML). The system batches notifications atomically—all news items for a report are sent as a single batch to each channel, ensuring consistency and reducing API calls. Message formatting respects channel constraints (character limits, attachment limits, etc.) and supports templating for customization.
Unique: Implements atomic message batching across 9+ heterogeneous channels with provider-specific formatters and constraint-aware truncation. Single configuration enables simultaneous delivery to WeChat, WeWork, Feishu, Telegram, Email, ntfy, Bark, Slack, etc. without code changes.
vs alternatives: Supports more channels (especially Chinese platforms like WeWork, Feishu) than generic notification services, and batching reduces API calls and spam compared to per-item notifications.
Exposes TrendRadar's data and analysis capabilities as an MCP server, enabling AI agents and LLM applications to query trends, perform analysis, and generate insights through natural language. The MCP server implements tools for: (1) querying filtered news by keyword/date/platform, (2) retrieving trend statistics and hotspot rankings, (3) running custom analysis on news subsets, (4) generating reports in various formats. Clients (Claude, other LLM agents) can invoke these tools via MCP protocol, enabling conversational exploration of trends without direct database access. The server maintains state across multiple requests, allowing multi-turn conversations about trends.
Unique: Implements full MCP server exposing trend data and analysis tools to LLM agents, enabling conversational queries and multi-turn analysis workflows. Maintains state across requests and supports complex tool invocations (filtering, analysis, report generation).
vs alternatives: Enables conversational access to trends (vs. API-only access) and integrates with LLM agent workflows (vs. standalone tools), but adds operational complexity compared to simple REST APIs.
