Drillr · The Financial Research Data Backend for Agents

The financial MCP for AI agents. Scan markets. Build conviction. Track every signal. Cite every claim.

Browser sign-in. No API key to copy. Nine tools for agent research: standardized financial data, company discovery, semantic news and event search, paragraph-cited company filings, and alt-data.

⭐ If drillr helps your agent, star us — that's how we know to keep building this in the open.

Quick Start

1. Sign up at drillr.ai

2. Add https://gateway.drillr.ai/mcp/data to an OAuth-capable MCP client

3. Sign in and approve the named client in your browser. No secret is displayed or copied.

Claude Code

claude mcp add --scope user --transport http drillr \
  https://gateway.drillr.ai/mcp/data
claude mcp login drillr

Codex CLI

codex mcp add drillr --url https://gateway.drillr.ai/mcp/data

Codex starts browser sign-in during setup. For an existing entry, run codex mcp login drillr.

Claude Desktop / OAuth-capable hosts

{
  "mcpServers": {
    "drillr": {
      "type": "http",
      "url": "https://gateway.drillr.ai/mcp/data"
    }
  }
}

Restart the host after saving, then approve Drillr in the browser when prompted.

Cursor / VS Code

One click writes the server entry; your editor then signs you in through the browser.

API-key fallback

Use this only for REST or an MCP host that does not support browser OAuth. Create an external key at drillr.ai/developer/keys, store it as a secret, and add:

"headers": { "Authorization": "Bearer <YOUR_DRILLR_API_KEY>" }

Hermes Agent fallback

mcp_servers:
  drillr:
    url: 'https://gateway.drillr.ai/mcp/data'
    headers: { Authorization: 'Bearer <YOUR_DRILLR_API_KEY>' }

Other hosts

Any MCP-compatible host uses the same Streamable HTTP endpoint. Omit headers and use browser OAuth whenever the host supports it; otherwise use the API-key fallback above. Never configure OAuth and a static bearer header on the same server entry.

Smithery fallback

npx -y @smithery/cli install drillr/drillr --client claude

Smithery offers the API key as an optional field. Leave it empty on an OAuth-capable client and sign in through the browser instead.

Claude Code plugin fallback

This repo doubles as its own single-plugin marketplace. From Claude Code:

/plugin marketplace add Little-Grebe-Inc/drillr-mcp-server
/plugin install drillr

The plugin installs the server without a key. Restart Claude Code, run /mcp, pick drillr, and choose Authenticate.

Hello World

Once configured, ask your agent something like:

"Pull NVDA's last 10-Q gross margin and compare it to AMD's same quarter — flag any divergence in segment mix."

What happens under the hood:

1. Your host routes the question to the drillr MCP server

2. The agent picks the right tools — typically sec_report_search (10-Q content) and run_sql (financial_statements for margins)

3. You get back a markdown answer with sources cited, typically in 8-15 seconds

4. Check your remaining credit balance at drillr.ai/developer/keys; REST clients additionally get an inline { "data": ..., "_credits": ... } envelope on every 2xx (see REST API › Response Envelope) — MCP responses follow standard JSON-RPC and do not carry per-call credit info inline

One Toolkit, 9 Tools

drillr exposes a single MCP endpoint with 9 tools — an all-in-one toolkit for most financial research workflows:

Full tool reference: docs/tools.md.

What's Covered

• Core equity coverage: US, Japan, Hong Kong, and China A-shares. Ticker formats: AAPL, 6758.T, 00700.HK, 600519.SH / 300750.SZ.

• Ontology-based Company Search: Search over the universe of equities with business model descriptions, supply chain positions, growth vector or thematic fit.

• Fundamentals: financial_statements, company_snapshot, and price_volume_history cover all four core markets; financial history reaches back to the 1980s

• Company filings: SEC EDGAR, Japan EDINET, HKEX, and China A-share reports with paragraph-level semantic search

• Earnings: call transcripts with AI-structured summaries and estimate-vs-actuals history; this specialized dataset covers US + Japan

• Markets: equities, ETFs, indices, forex, crypto, commodities

• Specialized US datasets: analyst ratings, ownership, executives, 8-K events, and extended-hours quotes

• News + events: continuously updating four-market and cross-asset search with story grouping and attributed claims

• AI value chain alt-data: energy & power, data centers, semiconductors, compute pricing, AI models / companies / benchmarks, LLM token pricing, macro & trade, prediction markets, critical minerals

Full data dictionary: docs/tools.md.

REST API

Every MCP tool has a 1:1 REST endpoint. Same drl_* key, same data, same billing. See docs/rest-api.md.

curl -X POST https://gateway.drillr.ai/api/v1/data/run_sql \
  -H "Authorization: Bearer $DRILLR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"sql":"SELECT ticker, close FROM price_volume_history WHERE ticker='\''AAPL'\'' AND time_frame='\''daily'\'' ORDER BY period_end DESC LIMIT 5"}'

Out of Scope

We're upfront about edges so your agent doesn't waste research loops:

• Private / unlisted companies (we cover public-listed only)

• On-chain crypto metrics — we have CEX prices (BTCUSD / ETHUSD / SOLUSD etc.), not TVL / holders / wallets

• Options chains, real-time order book, intraday tick data

• Retail brokerage actions (placing orders, managing positions)

• drillr does not produce its own price forecasts — we surface analyst consensus
