n8n stabilizes AI agent integrations with Anthropic thinking-block fixes across the 2.39-2.40 range

ai-agentsmcp-integrationworkflow-automationbug-fixesenterprise
◆Current state
n8n is in a dense patch cycle across versions 2.38-2.40, shipping multiple point releases per week. The primary focus is correctness in the AI Agent node — specifically preserving Anthropic thinking blocks with empty text across multi-step tool calls — and hardening the MCP toolkit execution layer for distributed worker environments. Source control reliability for enterprise git-backed workflows is also receiving attention.
◆Where it's heading
The pace and focus of fixes suggests the AI Agent and MCP features shipped in the 2.38-2.39 timeframe hit edge cases in production, and n8n is burning them down before moving forward. The pattern of MCP-on-workers and data-encryption key repair points toward enterprise deployments at scale being the forcing function for these fixes.
◆Prediction
Once this stabilization window closes, expect a release that either extends the AI Agent node's model support or formalizes the MCP toolkit interface; the two are clearly under active development simultaneously.

    n8n@2.40.0

    n8n 2.40.0 fixes the AI Agent node's handling of Anthropic thinking blocks with empty text during multi-turn tool calls — a correctness issue that would silently drop reasoning context between steps. This closes a gap in the AI integration layer that the 2.39.x cycle surfaced.

    n8n@2.39.5

    2.39.5 patches an editor-level issue that blocked some users from revoking end-user credentials — a minor but user-visible access-management fix.

    n8n@2.39.4

    2.39.4 corrects sandbox npm install flag selection by provider — an internal infrastructure fix with no visible user impact.

    n8n@2.38.7

    2.38.7 enables MCP toolkit members to execute on worker nodes, which is required for distributed deployments that offload execution — without this, MCP-based automations would fail silently in scaled environments.

    n8n@2.39.3

    2.39.3 adds trust for the CA specified in GIT_SSL_CAINFO for source control HTTPS remotes — a fix for enterprise deployments with internal certificate authorities.

    n8n@2.38.6

    2.38.6 caps peak memory during source control push operations — a meaningful stability fix for users running large workflow repositories where unbounded memory could cause out-of-memory failures.
