Forge never holds, brokers, or transmits a credential value — replace each in your own config file. Do not send a value back to Forge; no Forge endpoint accepts one. - This entry needs 1 credential (0 required). The generated config carries placeholders, so it will fail in the editor rather than at runtime if they are left unset. ## Blast radius Moderate blast radius — holds an api key; runs on your machine. - Floor 23, ceiling 23 (tier: moderate) - This is impact, not likelihood. A high radius is not a defect: a filesystem server is supposed to write files. It is never part of the trust score. ## Machine-readable views of this entry - Signed JSON: https://forgeregistry.com/api/v1/packages/%40three-ws%2Fblender-mcp - Install plan: https://forgeregistry.com/api/v1/packages/%40three-ws%2Fblender-mcp/install-plan - Alternatives: https://forgeregistry.com/api/v1/alternatives/%40three-ws%2Fblender-mcp - HTML page: https://forgeregistry.com/registry/%40three-ws%2Fblender-mcp - MCP: POST https://forgeregistry.com/api/mcp → `forge_get_package` / `forge_install_plan` ## About this document Generated by Forge (https://forgeregistry.com) — a compact rendering of the same record served, signed, at the JSON URL above.
