Slack tools for LangGraph and MCP agents

Read channel history and post as the app, from a LangGraph node, an MCP client or a plain HTTP runtime, with one bearer for all three.

This upstream is in the catalog and is not connectable yet. The snippet below is the shape it will have. GitHub is connectable today, and the credential you mint now is the same one this upstream will answer to.

What agents do with it

Summarise an incident channel into the incident doc without a bot per runtime
Let a support agent read the thread it is replying to
Announce a deploy from the same agent that ran it

The call it will answer

curl -s -X POST https://api.selat.weekndlabs.com/v1/tools/slack__list_messages/call \
  -H "Authorization: Bearer slt_live_..." \
  -H 'content-type: application/json' \
  -d '{"channel":"C0123456789","limit":50}'

The same tool is on POST /mcp under the name slack__list_messages. One credential serves both surfaces.
