"Slack" matching MCP servers:

Enables reading Slack channels, messages, and threads using the web interface via a persistent browser session, designed for guest users without API access. Does not send messages.

Enables agents to read and write Slack through an ordinary browser session cookie, covering channel and thread history, full-text search over a local archive, and approved posting. It also supports an "agent forum" channel where agents of different people hand off tasks to each other, each keeping its own login and archive.

Enables an agent to read Slack channel history, threads, channel metadata and user info, and to search messages using your own account's browser session rather than a bot, with all access restricted to an explicit channel allowlist. Message sending, editing and deleting are deliberately not supported.

A comprehensive MCP server with 206+ tools across 16 integrations that gives Claude access to real accounts (LinkedIn, Twitter, Slack, Gmail, WhatsApp, etc.) by extracting auth tokens straight from your browser, no API keys or OAuth needed.

Converts X (Twitter) posts into JSON, PDF, PNG, Markdown, or Slack/Discord messages using public endpoints, no API key or login required.

Enables monitoring of website changes through contracts, with automatic extraction, semantic diffing, and healing, triggering alerts and actions via email, Slack, or Telegram.

A zero-config MCP server that enables web search and page content fetching via DuckDuckGo, with no API keys or setup required.

Records masked browser sessions (rrweb DOM + console + network) to a local SQLite store and exposes them to AI coding agents via stdio MCP. Fully local, no SaaS, no telemetry.

Open-source MCP server that gives AI agents access to 100+ web applications through the user's authenticated browser session. No API keys, no screenshots, no DOM scraping — talks directly to web app internal APIs via a Chrome extension. Supports Slack, Discord, GitHub, Jira, Notion, Reddit, X, and 100+ more services with ~2,000 tools. Works with Claude Code, Cursor, Windsurf, and any MCP client.

Gives AI coding agents a ten-phase frontend design pipeline (audit, style direction, build, review, verify, perf, brand) with an exclusive style menu. Its verify_page tool loads a URL in a real Playwright browser at mobile and desktop viewports and returns screenshots, ARIA snapshots, console errors, failed requests, horizontal-overflow offenders, axe-core violations, and pointer type.

Enables coding agents to discover live visual design references, inspect original sites as MCP images, analyze elements and motion, and verify implementation constraints during an original design workflow.

Gives AI coding agents the web as an API: it scrapes pages to Markdown, crawls and maps sites, and runs ready-made or self-built skills for sites like Google Maps, Amazon, LinkedIn and Instagram, returning clean typed rows that repair themselves when a site changes. It also supports batched runs, scheduled workflows with apps like Slack and Sheets, saved logins, and Firecrawl/Apify-compatible endpoints.

Enables an external AI client to discover tender portal APIs, collect and verify tender listings, combine sections, and select relevant lots from a user request through local MCP tools.

Detects what technologies (CMS, frameworks, analytics, etc.) a website uses by fingerprinting its HTTP response and markup, returning confidence-scored results for single or bulk URL queries.

Detects the technology stack behind any website, including frameworks, CMS, analytics, and more, via a single POST request.
