Beta. MCP discovery is live. Authenticated tool calls use subscription API keys. Autonomous per-call payments are not part of the active paid offer.

Crypto developer intel that agents can query over MCP.

BuilderGraph indexes crypto repos and contributors across ecosystems mapped from Electric Capital. The data speaks MCP — point a remote MCP client at the server to discover the read tools. Use a subscription API key for authenticated calls.

The pitch in one paragraph

Crypto research agents need ground-truth on which projects have real developer activity. GitHub stars and Twitter mentions are easy to fake. Continuous, ecosystem-mapped commit graphs aren’t. BuilderGraph is an agent-callable MCP server that joins Electric Capital’s ecosystem taxonomy with GitHub metadata and week-over-week deltas.

Install in one of three ways

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "buildergraph": {
      "url": "https://api.buildergraph.dev/api/mcp"
    }
  }
}

Cursor / Continue

Add the remote MCP server:

{
  "mcp.servers": {
    "buildergraph": {
      "transport": "http",
      "url": "https://api.buildergraph.dev/api/mcp"
    }
  }
}

Raw HTTP (REST)

Prefer REST? Hit the discovery endpoint for server info and the available beta surface:

curl https://api.buildergraph.dev/api/agent
# → JSON: server info + available tools

What agents actually do with this

Crypto VC due-diligence agent

Triage a thesis-stage ecosystem in one round trip.

ecosystem_snapshot("monad")
ecosystem_graph("monad")
→ builder momentum, language mix, top repos, WoW deltas

Ecosystem activity agent

Rank active Rust + Solana repos by recent commits.

search_repos({ language: "Rust", ecosystem: "solana" })
repo_signal(top_repos[])
→ repos ranked by commit recency and momentum

Portfolio monitoring agent

Track when a watched repo loses momentum.

repo_signal("vyperlang/vyper")
repo_diff("vyperlang/vyper", since: last_check)
→ delta in stars / forks / contributors + pulse change

Just want to try it?

No wallet, no signup. Returns server info and the beta agent surface as JSON.

curl https://api.buildergraph.dev/api/agent

Need higher limits or exports?

A Pro or Team subscription issues a bg_live_* API key for authenticated access, higher request limits, and bulk exports.
