# Rengi Forge (io.github.MRRengi/rengi-forge): tool descriptions scored - tools/list taken: 2026-11-02 (UTC) - From: [Official MCP Registry](https://registry.modelcontextprotocol.io/v0/servers/io.github.MRRengi%2Frengi-forge/versions/latest) - Connected to: https://rengi.dev/mcp - Scoring rules: v2 - Tools: 43 - Average: 33.0 / 100 (Rain) - Near-identical pairs: 36 This page shows how Rengi Forge (io.github.MRRengi/rengi-forge)'s tool descriptions scored, the issues found and the names of its tools and parameters. The descriptions are the server's own: read them where the copy came from. Forecall asked the URL this server lists in the official MCP Registry for its tools/list once, on the date above, without calling any tool. The server may have changed since. ## Across the server - Major: 43 tools. Above 40, models choose less accurately. - Minor: 36 pairs with nearly the same description in all; the top 12 are shown. - Minor: The server has no instructions. Say there, once, what the server is for and when to use it: Claude Code and Gemini CLI read the instructions before the tool descriptions. ## Tools - `asset_render_sprites`: 24 / 100 - Major: Says nothing about when to use it, or when not to. - Major: Arguments without a description: glbUrl, upAxis, directions, cellSize, elevationDeg, pixelArt. - Minor: String arguments with no constraint or example: glb. - Minor: No `required` list, so every argument is optional. - Minor: The meaning of the boolean argument pixelArt is unclear. - Minor: Says nothing about what it returns. - Minor: No constraints, side effects, auth or rate limits described, and no annotations. - `glb_optimizer_inspect`: 24 / 100 - Major: Says nothing about when to use it, or when not to. - Major: Arguments without a description: glb, glbUrl. - Minor: String arguments with no constraint or example: glb. - Minor: No `required` list, so every argument is optional. - Minor: Says nothing about what it returns. - Minor: No constraints, side effects, auth or rate limits described, and no annotations. - `level_design_revise_2d`: 24 / 100 - Major: Says nothing about when to use it, or when not to. - Major: Arguments without a description: jobId, instruction, edits, edits[].zoneId, edits[].rules, edits[].rules[].kind, edits[].rules[].names, edits[].rules[].tags, edits[].rules[].density, edits[].rules[].kind, edits[].rules[].names, edits[].rules[].tags, edits[].rules[].inset, edits[].rules[].spacing, edits[].rules[].kind, edits[].rules[].names, edits[].rules[].tags, edits[].rules[].clusters, edits[].rules[].count, edits[].rules[].radius, edits[].rules[].kind, edits[].rules[].names, edits[].rules[].tags, edits[].rules[].kind, edits[].rules[].name, edits[].rules[].at. - Minor: String arguments with no constraint or example: jobId, edits[].zoneId, edits[].rules[].kind, edits[].rules[].kind, edits[].rules[].kind, edits[].rules[].kind, edits[].rules[].kind, edits[].rules[].name. - Minor: Says nothing about what it returns. - Minor: No constraints, side effects, auth or rate limits described, and no annotations. - Minor: Required identifiers whose description does not say where the value comes from: jobId.
