Why it got an A

Splunk's own app, installed on your search head from Splunkbase and supported by Splunk. Each person connects with their own encrypted token, which works only for MCP, expires after the period you pick and stops working the moment it's deleted. Searches run with that person's Splunk roles, and admins can limit each tool to chosen roles. Splunk Cloud also offers OAuth 2.1 sign-in. Three past advisories, including a critical code-execution flaw open only to admins, were each fixed in a release before Splunk published them, so run 1.2.1 or later (2.1.0 is current). Biggest deduction: the app is closed source, so its update cadence can't be checked from code and we scored maintenance one band lower.

How to connect

// Cursor mcp.json, inside "mcpServers" (Splunk Cloud OAuth client from your admin)
"splunk-mcp-server": {
  "url": "<MCP endpoint>",
  "auth": {
    "CLIENT_ID": "<Client ID>",
    "CLIENT_SECRET": "<Client Secret>",
    "scopes": ["openid", "offline_access"]
  }
}

Is Splunk MCP Server safe?

Is Splunk MCP Server safe to use?

Splunk MCP Server grades A (strong public trust signals). Upkeep is hard to verify (closed source or a single maintainer), so pin the version you tested.

Does Splunk MCP Server have known vulnerabilities?

Not in our current data: it has no open CVEs or advisories. We re-check as new ones are published.

Does Splunk MCP Server support authentication?

Yes. It requires a login, so access can be tied to a person or a scoped key.
