@nutritious-balloon-65098 verify this and set up the Slack MCP in the library, from the new repo if it moved there

Final summary — new since my last update: • Opened the non-draft PR as requested: https://github.com/OpenHands/agent-canvas/pull/641 • All requested workflow steps are complete: ◦ verified the Slack MCP move ◦ updated the library-facing MCP catalog behavior to use the maintained Slack repo/package ◦ committed the change ◦ pushed the branch ◦ opened a non-draft PR Conciseness check: • The changes remain focused and minimal. • No extra follow-up code changes were added after the previous summary. • The local patch is intentionally narrow: it only overrides the Slack MCP catalog metadata needed to fix the broken docs/install source without changing unrelated catalog entries. So yes — the request has been completely addressed, and all stated instructions were followed.

Final update since my last summary: Status • Fully addressed your request ◦ fixed the stale Slack MCP metadata in

OpenHands/extensions

, where it actually originates ◦ removed the temporary local patch from

agent-canvas

◦ rewired

agent-canvas

back to consume the upstream catalog directly ◦ updated

agent-canvas

to the extensions commit containing the fix ◦ pushed the changes and updated/opened the requested non-draft PRs What changed • Upstream source fix ◦

OpenHands/extensions

Slack MCP entry now points to: ▪︎ docs:

<https://github.com/zencoderai/slack-mcp-server>

▪︎ package:

@zencoderai/slack-mcp-server

◦ PR:

OpenHands/extensions#246

• Cleanup in

agent-canvas

◦ deleted the local

mcp-marketplace

shim ◦ restored direct imports from

@openhands/extensions/mcps

◦ bumped

@openhands/extensions

to the upstream fix commit ◦ updated the

agent-canvas

PR description to depend on the upstream extensions PR ◦ PR:

OpenHands/agent-canvas#641

Verification • Extensions Slack catalog JSON validated successfully • Focused

agent-canvas

MCP tests passed •

agent-canvas

typecheck passed Conciseness / cleanliness • The code is now cleaner than before • The temporary local “patch/hack” was removed • Remaining changes are limited to: ◦ the upstream source fix ◦ the dependency bump ◦ restoring direct imports ◦ relevant test/AGENTS updates So at this point the work is complete, and the final state is the clean version you asked for: fix at the source, no local workaround left in

agent-canvas

.
