Solidit Server

npm version License: MIT

Give AI assistants instant access to Solodit's 49,000+ blockchain vulnerability database.

An MCP server that connects Claude (and other MCP clients) to the Solodit audit findings API -- search vulnerabilities, browse recent discoveries, and look up specific findings directly from your AI workflow.

Runs via npx solidit-mcp-server with zero global installation required.

Quick Start

1. Get an API key at solodit.cyfrin.io (Profile > API Keys)

2. Add the MCP config (see Claude Code or Claude Desktop below)

3. Start using it -- ask Claude something like:

   "Search for reentrancy vulnerabilities in DeFi protocols"

Claude Code

Add to your .mcp.json (project-level) or ~/.claude/mcp.json (global):

{
  "mcpServers": {
    "solodit": {
      "command": "npx",
      "args": ["-y", "solidit-mcp-server"],
      "env": { "SOLODIT_API_KEY": "your-api-key-here" }
    }
  }
}

Claude Desktop

Add to your Claude Desktop config file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "solodit": {
      "command": "npx",
      "args": ["-y", "solidit-mcp-server"],
      "env": { "SOLODIT_API_KEY": "your-api-key-here" }
    }
  }
}

Docker

Build and run locally:

docker build -t solidit-mcp-server .
docker run -i -e SOLODIT_API_KEY=your-api-key-here solidit-mcp-server

Or use docker-compose with a .env file:

# .env
SOLODIT_API_KEY=your-api-key-here

docker compose up

language	string[]	Language: Solidity, Rust, Cairo, Vyper, Move
protocol	string	Protocol name (partial match)
finder	string	Auditor handle (partial match)
quality_min	number	Minimum quality score (0-5)
rarity_min	number	Minimum rarity score (0-5)
date_range	string	Preset: 30, 60, 90 days, or alltime
date_after	string	Custom date cutoff (ISO format, e.g. 2024-01-01)
sort_by	string	Recency, Quality, or Rarity
sort_direction	string	Desc or Asc

get_finding_detail

Retrieve the full content and metadata of a single finding by ID or slug. Use after seeing a result in search_findings to get the complete writeup.

Parameter	Type	Description
finding_id	string	The finding ID (UUID) or slug from search results or Solodit URLs

Example: "Get the full details of finding abc-123-def"

search_by_tag

Search by vulnerability tags, sorted by quality score (best examples first). Ideal for finding high-quality writeups about a specific vulnerability class.

Parameter	Type	Description
tags	string[]	Required. One or more vulnerability tags
impact	string[]	Severity filter: HIGH, MEDIUM, LOW, GAS
language	string[]	Language filter
protocol_category	string[]	Protocol category filter
page	number	Page number (default: 1)
page_size	number	Results per page (default: 10, max: 100)

Example: "Find the best oracle manipulation examples in Solidity"

recent_findings
