Stop guessing which one. Put them side by side.

The grid says what these tools are. This says what builders did about it — one decision per person, changeable whenever you change your mind.

# Tool comparison — Slack MCP Server (korotovsky) vs Chrome DevTools MCP vs Cline MCP Marketplace

Source: Kbaise, a directory of tools that work with Lovable projects.
Pick one and tell me why before writing any integration code.

## Slack MCP Server (korotovsky) (slack-mcp-server)
- URL: https://github.com/korotovsky/slack-mcp-server
- Category: MCP servers & registries
- Cost: free — Free, MIT
- What it is: The most widely used Slack MCP server, MIT-licensed and not affiliated with Slack. It supports bot and OAuth tokens plus a 'stealth mode' using browser session tokens that needs no app install or admin approval. It fetches channel and thread history, searches messages, adds reactions, marks read and posts.
- Why builders pick it: The realistic way to give an agent Slack context when you are not a workspace admin and cannot get an app approved. Message posting is off by default, so read-only triage works safely out of the box.
- Trap: Stealth mode hands long-lived browser session cookies to a community binary and may breach your workspace policy. The MCP steering group's Slack reference server is archived, so every option here is community-maintained.

## Chrome DevTools MCP (chrome-devtools-mcp)
- URL: https://github.com/ChromeDevTools/chrome-devtools-mcp
- Category: MCP servers & registries
- Cost: free — Free, open source
- What it is: Maintained by Google's Chrome DevTools team. It lets a coding agent control and inspect a live Chrome browser with full DevTools access: performance traces and insights, console messages with source-mapped stack traces, network request inspection, screenshots, DOM interaction, Lighthouse audits and memory debugging.
- Why builders pick it: Closes the loop where the agent writes frontend code but cannot see the result. It reads the real console error and the real network waterfall instead of asking you to paste a screenshot.
- Trap: If you attach it to an existing Chrome instance it drives your real profile and logged-in sessions — never point it at anything sensitive. Performance traces return very large payloads.

## Cline MCP Marketplace (cline-mcp-marketplace)
- URL: https://github.com/cline/mcp-marketplace
- Category: MCP servers & registries
- Cost: free — Free
- What it is: A curated marketplace built into the Cline VS Code extension. Authors submit a server via GitHub issue with a repo URL and logo; reviewers weigh community adoption, developer credibility, project maturity and security, usually within a couple of days. On install, Cline handles setup and configuration autonomously.
- Why builders pick it: Removes the config-file step entirely — pick a server in the sidebar and the agent installs and wires it up. The human review gate makes it far safer than pulling from a 70,000-entry index.
- Trap: Only useful if you already use Cline, and the curated list is a tiny fraction of what Smithery or Glama index.

## Rules
1. Prefer the free tier when no budget was stated, and say what the ceiling is.
2. Read the full dossier before integrating.
3. Fetch /api/public/models before writing any AI model ID.

Agents can fetch the same thing: GET /api/public/compare?slugs=slack-mcp-server,chrome-devtools-mcp,cline-mcp-marketplace
