Pondlog Npn

Overview

Pondlog Npn is a Model Context Protocol server that connects to the USA National Phenology Network, providing access to bloom, leaf-out, and flight timing data collected by NPN observers. Any MCP-compatible AI assistant can call its tools directly, letting the model decide when to use phenology observations in conversations or agent workflows.

The server runs locally via the npm package @pondlog/mcp-npn, communicating over stdio. No authentication is required—it works immediately after installation. The current release is v0.1.5 under the MIT license, with source code available at andrewschristison/pondlog on GitHub.

Listed under Development on mcp.site, Pondlog Npn integrates with any MCP client including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and others. If you maintain this server, claim this listing to verify ownership, earn the Verified badge, and keep information current.
