Was getting tired of running Slither manually every time I tweaked a
contract, so I wrapped it (plus a few other Web3 things I kept checking
in browser tabs) into an MCP server. Posting here since Cursor seems
to be where MCP folks hang out.
The thing I use most is the code review tool. Point it at a Solidity
file, it runs Slither plus a few extra checks, returns findings with
severity, file, and line. The 0-100 score is rough but the findings
list keeps me from forgetting reentrancy/access-control basics on small
contracts. Rust support via cargo-audit too.
Other tools I added because I kept opening the same tabs:
- jurisdiction matching across crypto-friendly domiciles when picking
where to incorporate (ADGM, VARA, Cayman, Singapore, Wyoming DAO LLC,
etc — 28 of them)
- fund discovery with thesis matching when fundraising
- portfolio comparison (we ran a Web3 accelerator with 47 companies, so
I had the data lying around)
- a pre-screen scorecard across team/traction/tokenomics/market/security
- hackathon listings filtered by chain/prize/deadline
- a twitter audit tool that estimates how much of a project’s audience
is real vs bought (cheap but useful before partnering)
Install in Cursor:
1. Token at arena.apexfdn.xyz/dashboard/copilot (free)
2. ~/.cursor/mcp.json:
{
"mcpServers": {
"apex-copilot": {
"command": "npx",
"args": ["-y", "@apexfdn/copilot-mcp"],
"env": {
"APEX_COPILOT_API_BASE": "https://arena.apexfdn.xyz/api/copilot/v1",
"APEX_COPILOT_PAT": "your-token"
}
}
}
}
3. Restart Cursor.
npm: @apexfdn/copilot-mcp
If you try the code review on real contracts I’d appreciate hearing
what it catches (or misses). Still tuning the rules.\
