We couldn’t confirm it starts correctly

We ran the install command but it didn't respond within our test window — this can mean a slow first-time install rather than a real problem.

npx -y mcpay

No response to initialize.

This is an experimental automated check and can have false negatives — missing environment variables, a slow cold install, etc. It doesn’t necessarily mean something’s wrong. Last checked 7d ago.

Overview

zero-core-intel was an MCP server connecting AI agents to RugSlayer’s DrainBrain token-safety service for Solana tokens. It exposed free status and preview tools plus a paid full-analysis scan using API keys or x402 USDC payments. The service stopped on October 23, 2026; its endpoint now returns 410, and the associated API and payment routes are being retired.

Use cases

  • Review Solana token risk before analysis
  • Check a token’s quick risk category
  • Inspect honeypot and rug-stage indicators
  • Retrieve MCP tool pricing and service status

Key features

  • Solana token safety previews
  • DrainBrain risk scoring
  • Honeypot and rug-stage analysis
  • Risk flags and temporal prediction
  • API-key and x402 payment models

How Zero Core Intel works

What zero-core-intel does

zero-core-intel provided AI agents with token-safety data for Solana assets through RugSlayer’s DrainBrain service. Its purpose was to help an agent inspect a token’s risk before making a decision, with both a fast categorical preview and a more detailed analysis.

The project was formerly named Harvey Intel. It was built by RugSlayer and categorized as a finance and fintech tool because its primary function was crypto-token risk analysis rather than portfolio management or trading execution.

How it works

Agents connected to a remote MCP endpoint at https://agents.rugslayer.com/mcp. The server exposed free tools for discovering available operations and checking service status. A preview request returned one of four risk levels: LOW, MEDIUM, HIGH, or CRITICAL.

The detailed scan_token operation used DrainBrain to produce an outcome-calibrated risk score, honeypot information, rug-stage classification, risk flags, and a beta temporal prediction. That operation was priced at $0.01 and used USDC payments on Solana when accessed through the x402 flow.

Two access models were described. API-key users sent a bearer token in the MCP connection’s Authorization header. The documented tiers included a free allowance of 100 calls per day, a Pro plan with unlimited calls, and a PAYG plan with a monthly fee plus usage charges. Alternatively, MCPay could intercept a paid-tool request, arrange a USDC payment on Solana, obtain verification from the PayAI facilitator, and forward the request.

Setup and configuration

The documented remote configuration used an MCP server entry with the endpoint URL. API-key configurations added an Authorization: Bearer ... header. Direct connections without credentials were intended for free tools only.

The x402 example used npx mcpay connect with a Solana secret key and the Solana network selected. That workflow required the agent to respond to a PAYMENT_REQUIRED result before the paid tool could run.

Claude Code could be configured with the HTTP transport using:

Terminal
claude mcp add harvey-intel --transport http https://agents.rugslayer.com/mcp

Tools and capabilities

  • list_tools: returned the available MCP tools and their prices.
  • health: reported server status and payment configuration.
  • scan_token_preview: supplied a quick LOW, MEDIUM, HIGH, or CRITICAL risk classification.
  • scan_token: returned the full DrainBrain analysis, including score, honeypot result, rug stage, risk flags, and beta temporal prediction.

Limitations and notes

The service was retired on October 23, 2026. The remote endpoint now responds with HTTP 410, and the repository is archived for reference rather than operation. RugSlayer stated that the DrainBrain API and its payment routes end on October 29, 2026, so API keys, payment configuration, and the documented live setup should not be used for a new deployment.

The detailed scan was marked as a paid operation and its temporal prediction was identified as beta. DrainBrain scores were calibrated against the real outcomes of tokens previously scanned by RugSlayer, making the output an analytical signal rather than a guarantee about future token behavior.

Frequently Asked Questions about Zero Core Intel

zero-core-intel is an MCP server that connected AI agents to RugSlayer’s DrainBrain token-safety service for Solana tokens. Its main tools were list_tools, health, scan_token_preview, and scan_token, which exposed pricing, status, quick risk levels, and full risk analysis. The service is retired.

You cannot install a working instance from the archived service because its remote endpoint returns 410. The historical setup used the remote MCP URL, with Claude Code configured through its HTTP transport command.

Full scans were priced at $0.01 and could be paid with USDC on Solana through x402. Agents could also use a RugSlayer API key under a subscription or usage-based tier.

The preview returned a LOW, MEDIUM, HIGH, or CRITICAL risk level. The full scan added an outcome-calibrated score, honeypot result, rug stage, risk flags, and a beta temporal prediction.
