`v1.86.7` is a patch release on top of [`v1.86.6`](/release_notes/v1.86.6/v1-86-6). It backports cost-tracking recovery for interrupted Anthropic streams, adds a `no-mcp-servers` sentinel that scopes a key to zero MCP servers, caps Anthropic `cache_control` injection at the 4-block API limit, and bumps OpenSSL plus `cryptography`, `python-multipart`, `pydantic-settings`, and `pypdf` for CVE coverage.
