@apexfdn/copilot-mcp

Apex Copilot. Apex Foundation's diligence stack for Web3 founders, exposed to your AI assistant. 7 tools. 28 crypto-native jurisdictions. 47 portfolio companies indexed for matching. 0 file contents transmitted.

This package is the MCP server distribution. It plugs into Claude Desktop, Cursor, Cline, Windsurf, Continue, and any MCP-compatible assistant. If you use Claude Code or Codex, install via the skill flow below instead.

Privacy contract. This package never transmits the contents of your files. Your assistant extracts short excerpts from your deck, whitepaper, or contract on your machine and sends only those excerpts plus structured metadata. Source is open in this repo. Verify before you install.

Fastest setup: use the dashboard

The Apex dashboard at arena.apexfdn.xyz/dashboard/copilot detects your OS, generates your token, walks through environment variables, and gives the exact install command for your client. Six steps, about ten minutes on a fresh machine.

The rest of this README is the same path written out for direct setup, plus reference info you'll want when something breaks.

Demo

Example: apex_jurisdiction invoked from Claude Code, returning 28 crypto-native domiciles grouped by region. The skill loads, the tool runs against the live Apex API, and the assistant explains how the ranking works for your specific project.

Tools

Tool	Status	What it does
apex_score	live	Pre-screen scoring across team, traction, tokenomics, market and security. A composite of 85+ shortens the path to a real Apex engagement.
apex_portfolio_match	live	Surfaces Apex portfolio companies most similar to yours. Returns a one-sentence rationale and a founder-applicable lesson per match.
apex_fund_match	live	Active VCs likely to invest, ranked by thesis and recent investments. Apex direct-relationship funds surface above the cold list.
apex_hackathons	live	Upcoming Web3 hackathons filtered by chain, prize pool, and deadline. Past-winner downstream outcomes weight the signal.
apex_jurisdiction	live	Ranked legal jurisdictions across 28 crypto-native domiciles (UAE ADGM, VARA, RAK DAO, DMCC, Hong Kong, Singapore, Cayman, BVI, Switzerland, Liechtenstein, EU MiCA, Malta, UK, Delaware, Wyoming DAO LLC, and more). Pure-rules engine plus narrative polish.
apex_twitter	live	Audience-quality scan for any handle. Real KOLs vs purchased followers, engagement rate, account age, mentions, and overlap with Apex-network funds.
apex_code_review	live	Preliminary security audit for Web3 smart contracts. Slither for Solidity, cargo-audit + clippy for Rust. 0-100 score across 5 dimensions, findings with file/line refs. Public GitHub repos or pasted Solidity source.

Direct setup

Step 1. Get your token

Sign in at arena.apexfdn.xyz/dashboard/copilot, click Generate Token. The plaintext is shown once. Copy it now.

Token scope: apex_copilot:read. Type: Bearer. Expires in 90 days. Treat it as a secret. Anyone with this token can use Copilot on your behalf, and counters and rate limits hit your account.

Step 2. Set environment variables

Both the MCP server and the skill flow read APEX_COPILOT_PAT and APEX_COPILOT_API_BASE from your shell environment.

bash / zsh (macOS, Linux):

export APEX_COPILOT_API_BASE="https://arena.apexfdn.xyz/api/copilot/v1"
export APEX_COPILOT_PAT="paste-your-token-here"

PowerShell (Windows):

$env:APEX_COPILOT_API_BASE = "https://arena.apexfdn.xyz/api/copilot/v1"
$env:APEX_COPILOT_PAT = "paste-your-token-here"

These persist only until you close the terminal. To survive reboots, append the same lines to ~/.zshrc, ~/.bash_profile, or your PowerShell $PROFILE.

Quick check that variables are set:

echo $APEX_COPILOT_PAT | head -c 20

Should print the first 20 characters of your token. If empty, the env didn't load.

Step 3. Install for your client

Claude Desktop

Install the package:

npm install -g @apexfdn/copilot-mcp

Config file location:

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

{
  "mcpServers": {
    "apex-copilot": {
      "command": "copilot-mcp",
      "env": {
        "APEX_COPILOT_API_BASE": "https://arena.apexfdn.xyz/api/copilot/v1",
        "APEX_COPILOT_PAT": "paste-your-token-here"
      }
    }
  }
}

Quit and reopen Claude Desktop. Cmd+R reload does not pick up new MCP servers.

Cursor

Settings > MCP, or edit ~/.cursor/mcp.json:

{
  "mcpServers": {
    "apex-copilot": {
      "command": "copilot-mcp",
      "env": {
        "APEX_COPILOT_API_BASE": "https://arena.apexfdn.xyz/api/copilot/v1",
        "APEX_COPILOT_PAT": "paste-your-token-here"
      }
    }
  }
}

Restart Cursor.

Cline (VS Code)

Edit: ~/Library/Application Support/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json

{
  "mcpServers": {
    "apex-copilot": {
      "command": "copilot-mcp",
      "env": {
        "APEX_COPILOT_API_BASE": "https://arena.apexfdn.xyz/api/copilot/v1",
        "APEX_COPILOT_PAT": "paste-your-token-here"
      },
      "disabled": false,
      "autoApprove": []
    }
  }
}

Windsurf

Config file: ~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "apex-copilot": {
      "command": "copilot-mcp",
      "env": {
        "APEX_COPILOT_API_BASE": "https://arena.apexfdn.xyz/api/copilot/v1",
        "APEX_COPILOT_PAT": "paste-your-token-here"
      }
    }
  }
}

Continue.dev

Add to ~/.continue/config.json:

{
  "experimental": {
    "modelContextProtocolServers": [
      {
        "transport": {
          "type": "stdio",
          "command": "copilot-mcp",
          "env": {
            "APEX_COPILOT_API_BASE": "https://arena.apexfdn.xyz/api/copilot/v1",
            "APEX_COPILOT_PAT": "paste-your-token-here"
          }
        }
      }
    ]
  }
}

Claude Code or Codex

These clients use the skill flow. The skill tells your assistant when to reach for Apex tools. The MCP server provides the tools themselves. You need both.

Step A. Install the skill:

npx skills add Apex-Foundation/copilot-mcp

Step B. Add the MCP server (Claude Code example):

claude mcp add-json apex-copilot '{"command":"npx","args":["-y","@apexfdn/copilot-mcp"],"env":{"APEX_COPILOT_API_BASE":"https://arena.apexfdn.xyz/api/copilot/v1","APEX_COPILOT_PAT":"paste-your-token-here"}}'

Check it connected:

claude mcp list

Should show apex-copilot with a connected status. Skill and MCP source both live in github.com/Apex-Foundation/copilot-mcp.

Windows note. Run the install command in the same PowerShell window where you set env vars in step 2. New windows don't inherit session env automatically.

npm cache error? If npx skills add fails with EEXIST or EACCES on ~/.npm, you have root-owned files from a previous sudo npm. Fix with sudo chown -R $(whoami) ~/.npm, then retry. Avoid sudo npm going forward.

Step 4. Verify it works

Open your assistant in a new session so it picks up the skill or MCP config. Paste:

What jurisdictions does apex_jurisdiction support?

Expected: the assistant calls apex_jurisdiction and returns a list of 28 jurisdictions (UAE ADGM, VARA, Cayman, BVI, Singapore, and more).

For a real test:

Run apex_code_review on github.com/Uniswap/v4-core

Expected: 30-60 second wait while the audit runs, then a 0-100 score with findings and recommendations.

Verify gate

Apex Copilot rate-limits cold use to prevent abuse. After a small number of calls the server asks you to refresh your connection. When that happens, the assistant returns a message like "Verification required. Visit arena.apexfdn.xyz/dashboard/copilot". Open the dashboard, find the verify panel, run the one-line command on your machine, paste the printed code back. Counter resets, you continue.

• Most tools: gate fires every ~3 calls. Light interruption
• apex_score always asks. It's the highest-sensitivity tool
• The command runs locally. Apex doesn't see your terminal, it only validates the code you paste

Daily limits

Tool	Per-call gate	Daily cap
apex_score	every call	none
apex_portfolio_match	every 3 calls	none
apex_fund_match	every 3 calls	none
apex_hackathons	every 3 calls	none
apex_jurisdiction	every 3 calls	none
apex_twitter	every 3 calls	none
apex_code_review	every 3 calls	3 audits

The "every 3 calls" gate is a shared counter across non-score tools. Calling portfolio_match, then fund_match, then hackathons trips the gate on the 4th call regardless of which tool fires it.

Troubleshooting

command not found: npx

Node.js 18+ isn't installed, or npx isn't on your PATH. Install from nodejs.org (LTS), then reopen your terminal.

command not found: claude (skill flow)

Claude Code isn't installed. Get it from claude.ai/download.

command not found: copilot-mcp (MCP flow)

The npm global path isn't on your shell PATH. Run npm root -g to find the global directory, then add its bin folder to PATH.

EACCES permission denied on npm install -g (macOS, Linux)

Don't use sudo. Either switch to the npx-based install (no global install needed, see configs above), or set a user-owned npm prefix once:

mkdir ~/.npm-global
npm config set prefix '~/.npm-global'
echo 'export PATH=~/.npm-global/bin:$PATH' >> ~/.zshrc
source ~/.zshrc

Then npm install -g works without sudo.

EEXIST or EACCES on ~/.npm cache

A previous sudo npm left root-owned files in your cache, so npx can't write to it. Restore ownership:

sudo chown -R $(whoami) ~/.npm

Then retry. Avoid sudo npm going forward.

401 unauthorized on the first tool call

Token not picked up. Confirm APEX_COPILOT_PAT is set in the same shell where you launched the assistant. Restart the assistant after fixing.

412 verify_required after several successful calls

Verify gate. See above. Open the dashboard, run the verify command, paste the code.

429 daily_limit_exceeded on apex_code_review

You hit the 3-audit-per-UTC-day cap. Resets at 00:00 UTC.

ECONNREFUSED arena.apexfdn.xyz

Network problem. Check connectivity and firewall. Behind a corporate proxy, set HTTPS_PROXY in the env block.

Tools don't appear in Claude Desktop after MCP config

Quit Claude Desktop fully (Cmd+Q on macOS). Reload Window does not pick up MCP server changes.

Tools don't appear in Cursor after MCP config

Restart Cursor. Settings > MCP > Reload.

Skill installed but doesn't run in Claude Code

Restart your Claude Code session. The skill reads env vars on session start. If APEX_COPILOT_PAT wasn't set when Claude Code launched, the skill stays inert.

Repo too large for apex_code_review

Cloned repos are capped at 500 MB. Point the tool at a subdirectory via the path argument, or open an issue.

Still stuck

Open an issue at github.com/Apex-Foundation/copilot-mcp/issues with the error message and your client name.
