Compare two AI tools side by side
Put any two skills or MCP servers next to each other: risk grade, what each can access, how popular it is, and how to install it.

| Risk grade | BB · Some risk signals Based on public adoption and transparency signals as of Oct 24, 2026.

| Type | App connector | App connector |
| Est. context load | ~700 tokens / turn (~4 tool schemas, 0.35% of 200k context) | ~3.8k tokens / turn (~22 tool schemas, 1.9% of 200k context) |
| GitHub stars | 529 | 54.4k |
| Weekly npm downloads | 5.9k | 3.3M |
| Local files | No local folder access noted | Reads & writes local folders |
| Command execution | No shell command runner noted | Runs shell or system commands |
| Network reach | Fetches arbitrary web URLs | Fetches arbitrary web URLs |
| Credentials | No API token required | Requires API key or token |
| Package source | npm (@mozilla/firefox-devtools-mcp-moz) | npm (chrome-devtools-mcp) |
| Install command | npx -y @mozilla/firefox-devtools-mcp-moz | npx -y chrome-devtools-mcp |
| Bottom line | firefox-devtools-mcp fetches arbitrary web URLs; restrict its folder reach, network access, and credentials before installing. | chrome-devtools-mcp (MCP server) requires careful permission scoping — credential exposure: Agents gain full access to Chrome DevTools, which may expose session cookies, auth tokens, and stored credentials to injected prompts or malicious agents. |
