Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Track what 1,000+ VCs follow on X to surface startups before their round. Signal for AI agents.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

VC follow intelligence for AI agents. Track what top investors follow on X — detect new follows, convergence signals, and trending companies before they're announced.
33 tools. Version 2.5.2.
No API key needed. Log in with your frontrun.vc account:
# Step 1: Log in — opens browser, saves credentials locally
npx frontrun-mcp-server --login
npx frontrun-mcp-server --setup # Claude Desktop npx frontrun-mcp-server --setup-code # Claude Code (uses claude mcp add)
Credentials are saved to ~/.frontrun/credentials.json. Other commands:
npx frontrun-mcp-server --status # Check auth status
npx frontrun-mcp-server --logout # Clear saved credentials
The server is also hosted at https://www.frontrun.vc/mcp (streamable HTTP). Point any remote-capable MCP client at it with your API key:
claude mcp add --transport http frontrun https://www.frontrun.vc/mcp --header "Authorization: Bearer sig_your_key_here"
If you prefer to use an API key directly, go to frontrun.vc → Settings > API Keys and generate a key (starts with sig_).
Claude Code
claude mcp add frontrun -e FRONTRUN_API_KEY=sig_your_key_here --scope user -- npx frontrun-mcp-server
Or add to .mcp.json in any project:
{
"mcpServers": { "frontrun": { "command": "npx", "args": ["frontrun-mcp-server"], "env": { "FRONTRUN_API_KEY": "sig_your_key_here" } } } }
</details>
Claude Desktop
Add to your config file:
~/Library/Application Support/Claude/claude_desktop_config.json%APPDATA%\Claude\claude_desktop_config.json{
"mcpServers": { "frontrun": { "command": "npx", "args": ["frontrun-mcp-server"], "env": { "FRONTRUN_API_KEY": "sig_your_key_here" } } } }
</details>
Cursor
Add to .cursor/mcp.json in your project:
{
"mcpServers": { "frontrun": { "command": "npx", "args": ["frontrun-mcp-server"], "env": { "FRONTRUN_API_KEY": "sig_your_key_here" } } } }
</details>
Any MCP-compatible client
FRONTRUN_API_KEY=sig_your_key_here npx frontrun-mcp-server
Open your AI tool and try:
"What's trending in my tracked accounts this week?"
Here are real prompts that work out of the box. Just type them into Claude Code, Claude Desktop, or Cursor.
Frontrun monitors the X (Twitter) follow graphs of VCs and investors you choose to track. When a VC follows a new account, Frontrun detects it, classifies the entity (startup, protocol, founder, etc.), and makes it queryable through AI.
The signal: VCs typically follow companies 2-8 weeks before a funding announcement. Convergence — multiple VCs independently following the same account — is the strongest signal.
Receipts: @techdollarhq flagged at 13 followers, $3M pre-seed announced 123 days later · @orthogonal_sh flagged 184 days before its $4.3M round led by Pantera · @rialto_xyz flagged at 18 followers, 26 days before its Robinhood partner announcement.
What you're paying for: Every response is computed intelligence, not raw data. Sectors are classified by AI, convergence is detected algorithmically, and company profiles are synthesized from multiple sources.
API + MCP access is included with the Pro plan ($99/mo) — it comes with 10,000 credits every month, and you can add more (or turn on auto-refill) at frontrun.vc/api/billing. Each query costs credits:
| What you're doing | Credits |
|---|---|
| Check your balance, list tracked accounts, manage rules/tags | Free |
| Preview an account, search, view sectors, pull a report | 4 |
| New follows, enriched follows, feed, company signals | 16 |
| Trending scan, VC activity | 24 |
| Thesis search, webhook setup (then 8/delivery) | 40 |
| Company deep-dive: overview, funding, convergence, resources, discover, similar VCs | 60 |
| Founder intelligence | 100 |
A typical daily check-in (feed + convergence + a few company deep-dives) runs ~300 credits — an included month covers it more than 30x over. Agent-scale usage is what auto-refill is for.
The agent has access to these tools automatically. You don't need to call them by name — just ask your question and the agent picks the right tool.
