MCP Today — 2026-08-18

Active MCP Repos & New Server Discovery

The punkpeye/awesome-mcp-servers list picked up 1 new entry in the last 24 hours: CatchAll (NewsCatcher) MCP server, added via a merged pull request. The list continues to be the canonical index for community-contributed MCP servers.

Three repositories tagged with model-context-protocol saw active pushes today:

• HKUDS/nanobot — 47,114 stars, pushed at 04:35 UTC. A high-star multi-agent framework with MCP support.
• PrefectHQ/fastmcp — 27,255 stars, pushed at 03:11 UTC. The fast MCP server framework maintained by Prefect.
• holaboss-ai/holaOS — 9,424 stars, pushed at 04:48 UTC. An MCP-connected OS-layer agent runtime.

MCP Continuous Releases

Two projects shipped releases in the past 24 hours:

• homeassistant-ai/ha-mcp released two automated dev builds: v8.2.0.dev2352 (04:04 UTC) and v8.2.0.dev2351 (03:48 UTC). These are pre-release builds of the Home Assistant MCP integration.
• jgravelle/jcodemunch-mcp shipped v1.108.284 at 22:14 UTC yesterday — "A documented setting the storage layer never read" — continuing its rapid patch cadence.

MCP Protocol Integration & Bug Reports

Three issues opened today highlight friction at MCP integration boundaries:

• Carry the MCP tool name into the UI contract (RorroRojas3) — proposes that the MCP tool name, not just the server name, should be surfaced in the UI layer contract.
• MCP stdio/local-process server support spec (gosharplite) — implementation spec for supporting COMMAND + ARGS-style local MCP servers alongside remote transports.
• [BUG] Interactive CLI fails after tool calls (yesinnk) — reports a regression in the Claude CLI where MCP tool calls leave the interactive session in a broken state, while claude -p and Desktop Code work reliably.

Slow-to-moderate day: one new server listed, steady dev-build release cadence, and integration friction surfacing at the protocol edges.
