geosphere-mcp-server: Instructions file for Codex

AGENTS.md

geosphere-mcp-server AGENTS.md is an instructions file for Codex, OpenCode from slettmayer/geosphere-mcp-server. It costs 1,895 tokens per session, scanned A, original, MIT.

Project instructions for GeoSphere MCP Server, a weather-data server for AI agents. It uses high-resolution GeoSphere Austria forecasts for Austria and the Alps, not worldwide weather data.

In plain words
What is it for?
Use them when developing, testing, documenting, or releasing the GeoSphere weather server.
Why use it?
They explain where the code lives, how to run tests and the server, and which documentation must change with behavior.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is slettmayer/geosphere-mcp-server's own configuration. It tells Codex and OpenCode how to work on geosphere-mcp-server itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything geosphere-mcp-server configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

geosphere-mcp-server AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.

GeoSphere MCP Server

MCP server for weather forecasts, usable by LLMs via the Model Context Protocol. High-resolution GeoSphere Austria data (AROME/INCA/C-LAEF/WRF-Chem) for Austria and the Alps only -- there is no worldwide fallback.

Editing this guide: AGENTS.md is the single source of truth for project context, read by all AI coding agents and humans. Keep it concise — put detail in docs/ and link it. When you change code that alters documented behavior, update the matching docs/ file in the same PR (CodeRabbit enforces this — see docs/README.md).

Quick Reference

  • Lint: ruff check .
  • Format: ruff format .
  • Test (unit): pytest tests/ -v -m "not integration"
  • Test (integration, live APIs): pytest tests/ -v -m integration
  • Run server: uvx --from . geosphere-mcp-server or python -m geosphere_mcp_server.server
  • Validate (CI): Ruff + pytest unit tests (all must pass via the gate job)
  • Release: run the Auto Release workflow; the version comes from the git tag -- see RELEASING.md

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
