Which versions of solana-dev-mcp are malicious?

Every published version of solana-dev-mcp on npm is considered malicious. Remove the package entirely.

How do I remediate solana-dev-mcp if I installed it?

Remove solana-dev-mcp from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

I already installed solana-dev-mcp — how do I know if it already compromised me?

If solana-dev-mcp was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.
