How to Use the Crypto Hash Engine MCP in Windsurf

Q: How do I add the Crypto Hash Engine to Windsurf?

Open your /.codeium/windsurf/mcpconfig.json file and add the server configuration under the mcpServers key. Windsurf auto-discovers tools once the MCP connection is established, allowing Cascade to access the hashing functions instantly.

Q: Can Windsurf use Crypto Hash Engine to sign Stripe webhooks?

Yes, Windsurf can call hashpayload with the raw Stripe event payload and your endpoint secret to generate the exact HMAC signature. This lets the agent verify your webhook handler code against real-world payload formats during local testing.

Q: How does Crypto Hash Engine protect my payload data and secrets in Windsurf?

Every request sent by Cascade to hashpayload runs in a zero-trust, isolated sandbox that destroys itself immediately after returning the hash. Your raw payloads and HMAC secret keys are never logged, cached, or stored on Vinkius servers.

Let Windsurf and Cascade autonomously sign your API webhooks and verify payloads with the Crypto Hash Engine MCP Server.

Cascade chains `hash_payload` for webhook verification

The `hash_payload` tool lets Windsurf handle crypto signing during multi-step integration builds without stalling. Cascade grabs your webhook payload, feeds it to this tool, and instantly gets the MD5 or SHA-256 signature needed to verify incoming requests. Because Cascade chains actions autonomously, it doesn't just generate the hash. It takes the output from `hash_payload`, writes the verification middleware in your Express or FastAPI code, and runs the tests to confirm everything matches up.

Secure HMAC generation with Windsurf and MCP

When your Cascade agent needs to sign outgoing requests, it calls `hash_payload` with your secret key to execute HMAC-SHA256 calculations. You don't have to write throwaway Node scripts or copy-paste keys into sketchy online tools just to see if your signature matches. Cascade handles the entire loop. It feeds the raw JSON and secret to the tool, receives the deterministic signature, and configures your project's environment variables to keep your secrets locked down.

Zero-hallucination hashing in your Windsurf workspace

The `hash_payload` tool stops LLM string hallucinations cold by running native cryptographic algorithms on Vinkius. Cascade invokes the server to get exact mathematical outputs for SHA-1 or SHA-512 hashes. This ensures that when Cascade is debugging a broken API handoff, it works with real, mathematically sound hashes rather than guessing hex strings.

Setup guide

Set up Crypto Hash Engine MCP in Windsurf

Prerequisites

Windsurf IDE installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP configuration

Click the Cascade assistant icon in the sidebar, then click the hammer icon (🔨) at the top of the panel. Select "Configure" to open ~/.codeium/windsurf/mcp_config.json.
2

Add the Crypto Hash Engine MCP

Paste the JSON snippet shown on the right into the mcpServers object. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Refresh MCPs

Go back to the hammer icon (🔨) in Cascade and click "Refresh". Windsurf will detect the new server. No full restart is needed — the connection is hot-reloaded.
4

Verify in Cascade

Start a new Cascade conversation and ask something like "Show my Crypto Hash Engine payment history." If connected, Cascade will call the Crypto Hash Engine tools directly. You will see a green dot next to the server name in the MCP panel.

Yes, Windsurf can call `hash_payload` with the raw Stripe event payload and your endpoint secret to generate the exact HMAC signature. This lets the agent verify your webhook handler code against real-world payload formats during local testing.

No, the server runs in a secure, ephemeral V8 isolate on Vinkius, which handles the computation when Cascade calls `hash_payload`. Your Windsurf client communicates with this remote sandbox via a single secure token, keeping your local dev machine lightweight.

Windsurf can specify MD5, SHA-1, SHA-256, or SHA-512 when calling the `hash_payload` tool. You can also pass an optional secret key parameter to generate secure HMAC signatures for specific API specs.

Every request sent by Cascade to `hash_payload` runs in a zero-trust, isolated sandbox that destroys itself immediately after returning the hash. Your raw payloads and HMAC secret keys are never logged, cached, or stored on Vinkius servers.
