Slack tools for LangGraph and MCP agents

List the channels a workspace exposes, resolve who is in it, 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

Announce a deploy from the same agent that ran it
Post a build result into the channel that owns the service
Resolve a display name to a user id before an agent mentions somebody

The call it will answer

HTTP

curl -s -X POST https://api.selat.weekndlabs.com/v1/tools/slack__list_channels/call \
  -H "Authorization: Bearer slt_live_..." \
  -H 'content-type: application/json' \
  -d '{"types":"public_channel"}'

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