3 Weeks on MCP Registry: Zero Tool Calls, Only Crawlers
suzuridev · reddit · 2026-08-04
An indie developer shared real-world data after listing their remote MCP server (providing semantic search over Japanese government docs) on the official registry for 3 weeks.
Key Observations:
- Zero Tool Calls: No real users have called the tool in three weeks.
- Crawler Spam: Of the thousands of daily requests, over half are irrelevant WordPress vulnerability scanners. The rest are from 4 MCP directory crawlers (e.g., AgenstryBot).
- Crawler Behavior: These bots initiate handshakes and list tools for health checks every few minutes, then leave.
The author expected to gain users via the registry but instead only gets monitored by bots. They are curious if developers running mainstream MCP servers face the same zero-call ratio.
