What's Wrong?

I have a cloud scheduled task with Linear and Slack MCP connectors attached. The connectors show as configured in the task settings UI, but when the task runs, no MCP tools are available to the agent.

What's happening:

  • ToolSearch for "Linear" → "No matching deferred tools found"
  • ToolSearch for "Slack" → "No matching deferred tools found"
  • The agent has no way to call any MCP tools despite connectors being configured
  • Task completes "successfully" (green checkmark) even though it couldn't do anything

What Should Happen?

What I expected:
MCP tools from the attached connectors should be available to the remote agent, similar to how they work in local Claude Code sessions.

Timeline:

  • Task created March 25, 2026
  • Manual run on March 26 worked correctly — MCP tools were available and the agent successfully queried Linear and posted to Slack
  • Last successful Slack post was March 31
  • Every run since April 1 shows green checkmark but MCP tools are not found
  • No changes were made to the task configuration during this period

Steps to Reproduce

Task config:

  • Trigger ID: trig_01YVmZNxqzun6ahgxbs8bjjS
  • Environment: claude-code-default (env_01AehNTFvLs5Cx18QAX33QsY)
  • Model: claude-sonnet-4-6
  • MCP connections: Linear (mcp.linear.app/mcp) and Slack (mcp.slack.com/mcp)
  • No git repository source (task only uses MCP tools + Bash)
  • allowed_tools includes both mcp__Linear__* and mcp__claude_ai_Linear__* variants

TL;DR

The issue can be resolved by re-examining the task configuration, specifically the MCP connections and allowed tools, to ensure they are correctly set up and compatible with the Claude Code version.

Guidance

  • Verify that the MCP connections for Linear and Slack are correctly configured and enabled in the task settings UI.
  • Check the allowed_tools list to ensure it includes the correct variants of the MCP tools (e.g., mcp__Linear__* and mcp__claude_ai_Linear__*).
  • Review the task configuration for any changes or updates that may have been made around April 1, which could be causing the issue.
  • Test the task with a manual run to see if the MCP tools are available and functioning as expected.

Notes

The issue may be related to a change in the MCP connections or the allowed_tools list, but without more information or error logs, it's difficult to determine the exact cause.

Recommendation

Apply workaround: Reconfigure the MCP connections and allowed_tools list to ensure they are correct and compatible with the Claude Code version, and then test the task again to see if the issue is resolved.
