Unreleased

Standalone BepInEx plugin exposing a localhost HTTP endpoint for driving Valheim's in-game console.
Plain HTTP routes for scripting: GET /health, GET /commands, POST /command.
Native in-process MCP transport (POST /mcp, Streamable-HTTP / JSON-RPC 2.0) with tools: run_command, list_commands, health, render_view.
Off-screen camera rendering (render_view) returning a PNG inline, without touching the player's view.
Dependency-free config at BepInEx/config/valheimmcp.yml, including an allow/deny command access-control list.

Output from commands that print asynchronously (coroutines, e.g. screenshot capture) is not captured — only output printed synchronously during the call.
