mc-pack-builder-mcp (dcd887/mc-pack-builder-mcp) is an MCP server listed on the M8ven Trust Index. M8ven has not graded it: we have no way to read this server ourselves. No publisher has claimed this listing.
Enables creating Minecraft modpack structures, searching Modrinth mods, resolving dependencies, and checking compatibility.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
8/8 tools missing one or more hints — create_pack (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_pack_info (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_mods (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +5 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Destructive tools are labelled
1 tool perform destructive updates without destructiveHint — export_standard_pack deletes at line 450 (fs.rmSync(target, { recursive: true, force: true }))
Add destructiveHint:true to any tool whose handler calls .delete(), .upsert(), .update(), unlink, rm, DELETE, DROP, REPLACE INTO, or any operation that overwrites existing data.
Tool test coverage
Only 0/8 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
