Independent Report on MCP Server Reliability and Security Findings
The first independent security and reliability report on MCP servers has been published, analyzing data from 2,181 remote MCP server endpoints. The report covers reliability, security, and maintenance metrics gathered through monitoring of publicly accessible endpoints.
Key Findings from the Analysis
- 52% of remote MCP server endpoints are dead
- 300 servers have zero authentication, meaning any agent can connect
- 51% have wide-open CORS (Cross-Origin Resource Sharing) configurations
- The finance category scores lowest on trust despite handling sensitive data
- Only 42% of servers with GitHub repositories have committed code in the last 30 days
Available Resources
The full report with detailed methodology is available at yellowmcp.com/report. Developers can test their own MCP servers using the tool at yellowmcp.com/test.

NanoClaw implements a security architecture where each AI agent runs in its own ephemeral container with unprivileged user access, isolated filesystems, and explicit mount allowlists. The codebase is deliberately minimal at around one process and a handful of files, relying on Anthropic's Agent SDK instead of reinventing functionality.
