Cadra (YASSERRMD/Cadra) 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.
Code-first, agent-first 3D video animation framework and studio, built on Three.js and WebGPU. One scene DSL authored in code, by an agent over MCP, or visually, rendered identically live or headless.
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.

Install from
M8ven verifies MCPs across every public registry — install directly from whichever one you prefer.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

Tool annotations
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
25/25 tools missing one or more hints — ping (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); upload_asset (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_assets (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +22 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
2 tools perform destructive updates without destructiveHint — delete_output deletes at line 204 (unlink(filePath)); prune_outputs deletes at line 298 (unlink(resolve(config.outputDirectory, file.fileName)))
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.
README present

Dev dependencies
2 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Dependency freshness
1/10 production deps stale: pngjs@2023-02-20 (3.5y)
Domain consistency
npm scope @cadra doesn't match GitHub owner yasserrmd
Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.
