Browser sign-in, no API key to copy. One hosted Streamable HTTP endpoint, ten tools: turn a name or a description into tickers, list and search a company's filings (structured as-reported facts and the filed text), run read-only SQL over the financial tables, and pull research signals from earnings calls and news.

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

## Install drillr MCP

To install or connect drillr MCP, read the [official installation guide](https://drillr.ai/developer/mcp-install.md).
It is the maintained source for client-specific setup, browser OAuth sign-in, and connection checks.

Paste this into the app where you want to use drillr:

```text
Please connect drillr MCP in this app using this installation guide: https://drillr.ai/developer/mcp-install.md. Walk me through sign-in and verify the connection.
```

The public server is `drillr-data` at `https://gateway.drillr.ai/mcp/data` (Streamable HTTP).
Browser OAuth is the default. The guide covers client-specific requirements and the API-key fallback for clients without OAuth support.

For manual setup and tool reference, see [drillr.ai/docs/mcp](https://drillr.ai/docs/mcp).

### Agent skill

The companion [drillr skill](https://github.com/Little-Grebe-Inc/drillr-skill) adds research workflows for MCP and REST. Installing the skill is optional for connecting the MCP server:

```bash
npx skills add Little-Grebe-Inc/drillr-skill
```

### Distribution options

- [Smithery listing](https://smithery.ai/servers/drillr/drillr)
- This repository also provides a Claude Code plugin marketplace:

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

After installing a plugin, use the official guide for sign-in and verification in the selected client.

## Hello World

> _"What does NVDA's latest 10-K say about supply commitments, and how did data-center revenue move over the last four quarters?"_

1. The agent calls `ticker_lookup` if it only has a name, `filing_list` to see what is indexed, then `filing_search` — which returns **as-reported facts** (value, period, XBRL concept, accession number) and the **passages** they sit in, in one call.
2. For the quarterly series it calls `run_sql` on `financial_statements`.
3. You get an answer whose every number cites its filing. Typical round-trip 8–15 s.

## The ten tools

Each tool has a page at `https://drillr.ai/docs/mcp/<tool>` with parameters, limits and error shapes; the server's `tools/list` carries the same descriptions. The set stays small on purpose: the agent composes them.

| Group | Tool | What it does | Cost |
|---|---|---|---|
| **Company** | [`ticker_lookup`](https://drillr.ai/docs/mcp/ticker_lookup) | Name, brand or ticker substring → canonical symbols, historical names included | free |
| | [`company_search`](https://drillr.ai/docs/mcp/company_search) | Natural-language description → companies with a match reason; US / CN / JP / HK / KR; all matches returned | 3–5 cr |
| **Filings** | [`filing_list`](https://drillr.ai/docs/mcp/filing_list) | Which filings are indexed for a ticker: fiscal period, type, filing date | 0.1 cr |
| | [`filing_search`](https://drillr.ai/docs/mcp/filing_search) | Search one company's filings; returns structured as-reported facts and the filing text together | 0.1 cr |
| **Datasets** | [`list_tables`](https://drillr.ai/docs/mcp/list_tables) | Alt-data category index, or the tables under up to five categories | free |
| | [`get_table_schema`](https://drillr.ai/docs/mcp/get_table_schema) | One table's columns, types and usage note — required filters, coverage, gotchas | free |
| | [`run_sql`](https://drillr.ai/docs/mcp/run_sql) | One read-only PostgreSQL SELECT over the financial, market and alt-data tables | 0.1 cr |
| **Signal** | [`industry_inflections`](https://drillr.ai/docs/mcp/industry_inflections) | Industry changes synthesized from many US earnings calls: mechanism, scope, degree, per-company impact | 1 cr |
| | [`ai_adoption`](https://drillr.ai/docs/mcp/ai_adoption) | Concrete enterprise AI applications disclosed on US earnings calls: workflow, stage, value, evidence | 1 cr |
| | [`news_search`](https://drillr.ai/docs/mcp/news_search) | Semantic search over company and market news: storylines, events, attributed claims | 0.2 cr |

## What the data is

Built by drillr from primary sources — filings taken from each market's official channel (SEC EDGAR, cninfo, EDINET) and parsed in house, what companies publish on the web (IR pages, earnings calls, news), and drillr's own estimates. No data vendor in between. Every reported figure links back to the passage it was filed in. Provenance per dataset: <https://drillr.ai/docs/provenance>.

| Dataset | What is in it | How to reach it | Coverage |
|---|---|---|---|
| **Company** | Ticker resolution from any name, code, ISIN, CIK or CUSIP; discovery by description; profile (exchange, industry, listing date, website, headcount) | `ticker_lookup`, `company_search`; `company_snapshot` via SQL | US CN JP (discovery + HK KR) |
| **Filings** | Filing index with form type, date and official link; full-text search in EN / ZH / JA; as-reported fact records with value, unit, period, filing and position, linked in a knowledge graph so the right version of a figure wins | `filing_list`, `filing_search` | US CN JP |
| **Financials** | Income statement, balance sheet, cash flow as reported under each market's standard, annual and quarterly; precomputed valuation, margin, return, growth, leverage and liquidity metrics | `run_sql` on `financial_statements`, `company_snapshot` | US JP HK CN KR |
| **Prices** | Daily / weekly / monthly OHLCV, indices, pre- and after-market quotes | `run_sql` on `price_volume_history`, `index_price`, `equity_extended_rt` | equities US JP HK CN KR; indices, FX, crypto, commodities |
| **Earnings** | Calendar with estimates and actuals; structured call summaries (highlights, guidance, risks, segments, Q&A) | `run_sql` on `earning_call_calendar`, `earning_call_summary` | US JP |
| **Ownership** | Insider holdings and transactions (Forms 3 / 4 / 5); institutional quarterly positions (13F-HR) | `run_sql` on `insider_and_institution_activities` | US |
| **Events** | 8-K corporate events: executive changes, deals, debt issuance, securities offerings; 13D / G stake changes | `run_sql` on `executive_change`, `company_deal_events`, `debt_issuance`, `securities_offering` | US |
| **Executives** | Roster with status; annual compensation from DEF 14A | `run_sql` on `executive_profile`, `executive_compensation` | US |
| **Analyst** | Individual rating and target changes; consensus distribution and targets | `run_sql` on `analyst_ratings`, `analyst_ratings_consensus` | US |
| **Signal** | Conclusions drawn by drillr with the evidence quoted: industry inflections, enterprise AI adoption, cross-source news storylines and attributed claims | `industry_inflections`, `ai_adoption`, `news_search` | US (news: US CN JP + macro) |
| Alt-data (secondary) | 9 categories, 65 tables around the AI supply chain and macro: energy & power, data centers, semiconductors, compute pricing, model development, inference economics, macro & trade, prediction markets, critical minerals | `list_tables` → `get_table_schema` → `run_sql` | global |

Ticker forms: US bare (`AAPL`), A-shares `.SH` / `.SZ` (`600519.SH`), Japan `.T` (`6758.T`), Hong Kong `.HK` (`00700.HK`), Korea `.KS` / `.KQ` (`005930.KS`); indices `^GSPC`; quote symbols with `.` or `^` in SQL. Freshness: filings, ownership and events within minutes of the filing; calls and news within minutes to hours; statements and analyst data daily.

Benchmark: the drillr MCP-powered model scores 94.06 % on Vals Finance Agent, and drillr publishes its own restatement-aware benchmark — <https://drillr.ai/drillr-benchmark>.

## REST API

The same data as 29 typed REST endpoints for scripts and pipelines — one `X-API-KEY` header, JSON out, public OpenAPI 3.1 contract:

```bash
curl -H "X-API-KEY: $DRILLR_API_KEY" \
  "https://gateway.drillr.ai/api/v2/income-statements?ticker=AAPL&period=FY&limit=4"
```

Reference: <https://drillr.ai/docs/api> · Contract: <https://gateway.drillr.ai/api/v2/openapi.json>. The older `/api/v1/data/*` tool mirrors are documented in [`docs/rest-api.md`](./docs/rest-api.md).

## Pricing and limits

One credit wallet across MCP and REST. Free: 80 credits on sign-up. Plus $29 / 300 cr per month, Ultra $99 / 1,500 cr, Enterprise for redistribution and SLA. `run_sql` returns 100 rows (500 on Ultra), 10 s per statement, 5 in flight; `company_search` is capped per day (20 / 100 / 500). Failed calls are not billed. <https://drillr.ai/pricing>

## Out of scope

Private or unlisted companies · on-chain crypto metrics (CEX prices only) · options chains, order book, tick data · placing orders · drillr does not produce its own price forecasts.
