Splunk MCP Integration for LangGraph

Connect Splunk to LangGraph through the local KosmoKrator MCP gateway with scoped tools, credentials, and write policy.

6 functions 5 read 1 write Bearer token auth

Connect Splunk to LangGraph

Run KosmoKrator integration calls from LangGraph nodes while preserving local credentials and permissions.

Use a graph node that calls the KosmoKrator CLI for deterministic steps or an MCP client for dynamic tool selection. The gateway is local, scoped to this integration, and starts with --write=deny so LangGraph can inspect read-capable tools without receiving write access by default.

Splunk MCP Config for LangGraph

Headless CLI calls fit repeatable graph edges; MCP fits exploratory agent nodes.
