Analysis of 2,181 Remote MCP Server Endpoints Shows Reliability Issues
A recent analysis of 2,181 remote-capable MCP server endpoints reveals significant reliability issues across the ecosystem. The automated health checks were conducted against servers from the official registry, mcp.so, PulseMCP, and Smithery.
Key Findings
- 52% of endpoints are completely dead (timeout, connection refused, 404)
- 37% respond but require authentication (401/403)
- 9% are confirmed up and healthy
- 1.5% are degraded (slow or intermittent errors)
- Among live servers, 516 maintain 99%+ uptime
- 58% of servers with GitHub repos haven't had a commit in 30 days
Category Breakdown
- Dev-tools has the most servers (1,238)
- Finance servers have the worst average latency (2,558ms)
- Security servers have the lowest average uptime at 27%
Fastest Servers Found
- GitHub MCP: 101ms
- Timescale pg-aiguide: 104ms
- Supabase: 109ms
The full dataset is available for further analysis, and the author is open to questions about methodology or specific servers.

Local vs Cloud Models: Qwen-3.6-27B, Gemma-4-31B, Claude Haiku, Codex-Spark on Hard Code Gen
A user tested Qwen-3.6-27B (q4_k_m) locally on an RTX 5080 against API-based Gemma-4-31B, Claude Haiku 4.5, and Codex-Spark on a complex code task. Only Codex-Spark produced complete code (but with import errors); all others failed partially. Cost: Gemma used $0.112 for 803k input tokens.
