Your MCP tools are running in parallel now
Codex CLI 0.134.0 runs MCP tools marked readOnlyHint concurrently by default. The change is small. The pattern it completes — three vendors flipping defaults toward more-automatic-less-consent in the same week — is the news.

Auditing your MCP config for leaked secrets
GitGuardian found 24,008 secrets in MCP config files on public GitHub. This is the audit pass: find committed config, detect inline keys, convert to environment variables, rotate what leaked, and stop it recurring.

MCP on Claude Code: from `mcp__` tool names to a working connection
MCP connects Claude Code to external tools without bundling everything into the agent. Here's how to configure servers, understand the tool-naming convention, and debug a server that won't show up.

Three MCP servers worth installing: Postgres, Notion, and Linear
Postgres, Notion, and Linear MCP servers extend Claude Code with live data access. Each has a clear use case and a specific gotcha that bites you if you skip the setup details.

MCP tools and Claude Code's tool-use loop: how they actually compose
Native tools and MCP tools look identical to the model. Understanding the lifecycle differences—and what happens when the tool list grows too large—makes MCP integrations reliable.
