What its author says it does

Copied from the file, not written here

Install and configure the Frontrun MCP server for Claude Desktop, Claude Code, Cursor, or any MCP client: one-command npx setup, browser OAuth login, hosted streamable-HTTP endpoint, and troubleshooting. Use when asked to set up or install the Frontrun MCP server, connect an agent to Frontrun, add VC deal-sourcing tools to an MCP client, or wire investor follow-graph signal into Claude or Cursor.

Frontrun MCP server setup

The Frontrun MCP server gives any MCP-capable client (Claude Desktop, Claude Code, Cursor, Codex) native tools over the same /v1 API: tracking, new-follow detection, convergence, trending, thesis search, and company deep-dives. 35 read-only tools mirroring the 35 REST operations.

Local install (two commands, ~1 minute)

npx frontrun-mcp-server --login    # opens browser OAuth sign-in; saves credentials to ~/.frontrun
npx frontrun-mcp-server --setup    # writes the Claude Desktop config

Claude Code users: npx frontrun-mcp-server --setup-code (wraps claude mcp add). Already have an API key (starts with sig_)? Skip login and pass it directly: npx frontrun-mcp-server --setup YOUR_API_KEY. The server reads FRONTRUN_API_KEY from its environment, so any MCP client can launch it with npx frontrun-mcp-server plus that env var. Restart the client after setup.

Try it with no key at all (free-sample mode)

The npx server starts fine with no key configured. Two tools work pre-auth:

trending_teaser: top 5 trending companies from the last 7 days (name, handle, sector, followers, first-flagged date, new tracked-investor follow count). Real data, counts only, no key needed.
send_feedback: report a confusing error, missing capability, or docs gap straight to the team, no key needed.

Every other tool returns sign-in instructions until a key is configured: the paywall sits at first authed use, not at install.

Hosted endpoint (no local install)

The same server runs hosted at https://www.frontrun.vc/mcp (streamable HTTP):

Auth: Authorization: Bearer <your API key>
tools/list works without auth (open install), tools/call requires the key: the paywall sits at first use, not at install.

Auth and pricing (the honest version)

API + MCP access is included with Frontrun Pro ($99/mo, 10,000 monthly credits; no trial on Pro, access unlocks immediately on payment). Keys are generated at https://www.frontrun.vc under Settings > API Keys, or via the --login OAuth flow. The app has a 7-day free trial, but MCP tool calls need a Pro key. A free no-auth public slice of the signal (counts only) lives at https://frontrun.vc/trending/.

Every tool result includes cost_credits and balance_credits. Rough per-call costs: status and tracking management free; search and reports 4; feed, new follows, and company signals 16; trending 24; thesis search 40; company deep-dives 60; founder intelligence 100. Empty answers on the expensive calls (convergence, thesis, founders, funding, similar VCs) cost 0.

Smoke test

Ask the connected agent:

call frontrun_status and tell me my credit balance.

which companies gained 3+ tracked-investor follows in the last 7 days?

Troubleshooting

401 on every call: the key is missing or invalid. Re-run --login, or check the FRONTRUN_API_KEY env var / Bearer header. Keys start with sig_.
402: out of credits. Top up or wait for the monthly reset; frontrun_status is free and shows the balance.
Tools listed but calls fail on the hosted endpoint: tools/list is open pre-auth by design; calls need the Bearer key.
