A Model Context Protocol server that exposes the canonical OSRS Calc knowledge surface — calculators, training plans, and reference data, FAQ, official links — to MCP-compatible AI clients such as Claude Desktop, Cursor, Windsurf, and Continue. Read-only, no API keys, no quota, ~50 ms cold start.
OSRS Calc is a browser-based Old School RuneScape planning toolkit. Its skill calculators estimate XP, actions, hours, and time to a target level across 24 skills, including Sailing.
The site also exposes DPS, Max Hit, Dry, Combat Level, prices, and wiki reference tools. This MCP provides the public calculator catalog and data caveats as read-only context; it does not access a player's account or promise that prices and wiki data are current outside the live site.
Old School RuneScape, RuneScape, and related names are owned by their respective rights holders. Check the live calculator and OSRS Wiki sources before making an in-game decision.
