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.

| Type | App connector | App connector |
| Est. context load | ~550 tokens / turn (~3 tool schemas, 0.27% of 200k context) | ~850 tokens / turn (~5 tool schemas, 0.43% of 200k context) |
| GitHub stars | 13 | 29.2k |
| Weekly npm downloads | 3.7k | — |
| Local files | No local folder access noted | No local folder access noted |
| Command execution | Runs shell or system commands | Runs shell or system commands |
| Network reach | Connects to outside service API | Connects to outside service API |
| Credentials | No API token required | Requires API key or token |
| Package source | npm (bestax-mcp) | npm (@mastra/mcp-docs-server) |
| Install command | npx -y bestax-mcp | npx -y @mastra/mcp-docs-server |
| Bottom line | bestax-mcp is distributed via npm (bestax-mcp); review its source code, dependencies, and requested permissions before use. | mastra (MCP server) requires careful permission scoping — agent permissions scope: Framework enables agents to access external systems; over-broad connector permissions could allow unintended data access or actions. |
