Summary
Agent Radar 2026-11-01: Playwright MCP 0.0.84 adds isolated browser contexts and URL redaction; FastMCP 4.1.4 adds rotating Redis credentials.
Agent Radar tracked two launches as of 2026-11-01, covering the window 2026-10-25 to 2026-11-01. Both are MCP tools, and both are new to the site, so each comes with a new tool hub. The one with an install change to check is FastMCP 4.1.4.

What changed
- Playwright MCP: v0.0.84, published October 31, 2026, lets tabs share or isolate cookies and storage by context name, so one browser can hold two accounts. It can mask named URL parameters such as
codeoraccess_tokenin tool responses, which the notes call a convenience, not a security feature. It also capsbrowser_findresults. See the new Playwright MCP hub. - FastMCP: 4.1.4, published October 26, 2026, accepts a redis-py credential provider for tasks and excludes Redis 8.1.0. It drops the unused
keyringdependency, so customKeyringStoreusers must installpy-key-value-aio[keyring]. See the new FastMCP hub.
