Source Intelligence

DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

MCP-CLI Removed

What

The experimental mcp-cli command-line interface for MCP servers has been removed.

Details
  • The ENABLE_EXPERIMENTAL_MCP_CLI environment variable is no longer recognized
  • The mcp-cli command (info, call, servers, tools, grep, resources, read) is removed
  • MCP tools continue to work through the normal tool interface

Impact: If you relied on mcp-cli commands in bash scripts or hooks, migrate to using MCP tools through Claude's standard tool interface.

Evidence

Removal of mcp-cli infrastructure (removed strings: "mcp-cli info", "mcp-cli call", "ENABLE_EXPERIMENTAL_MCP_CLI")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
