Version 1.1.0

Released April 1, 2026

Splunk MCP Server App version 1.1.0 adds support for configuring the Splunk platform as an OAuth 2.1 server for Model Context Protocol (MCP) connectivity, and introduces beta features for running saved searches and applying MCP Server rate limiting.

What's new

  • Added support for configuring the Splunk platform as an Open Authorization version 2.1 (OAuth 2.1) server that operates using the Model Context Protocol (MCP), enabling external applications to connect to and access data stored on the Splunk platform.

  • Controlled Access: OAuth 2.1 server configuration on the Splunk platform is currently a Controlled Access feature. Contact Splunk Support to enable or disable this feature in your environment. Speak with your Support representative for specific details.

  • Beta feature: Run Saved Search. Added the Run Saved Search tool to Splunk MCP, enabling AI assistants to run existing Splunk saved searches directly through MCP.

  • Beta feature: MCP Server rate limiting. Added rate limiting support for the MCP Server. Since the MCP Server can be accessed by multiple agents and shares critical resources with both the MCP app and the Splunk instance, rate limiting helps maintain app performance and security.

Notes and considerations

  • OAuth 2.1 server support is available only through Controlled Access.

  • Run Saved Search and MCP Server rate limiting are beta features in this release.

  • Configured rate limits apply per instance only.
