REST · GraphQL · MCP for AI agents

Your spreadsheet and the PDFs beside it. One relational API.

Connect the Excel workbook or Airtable base your team already lives in, add the invoices, contracts, or reports that go with it, and DocQuery links them into real tables with foreign keys. Query everything over REST, GraphQL, or MCP. When the sheet changes, the API follows.

Start free — no card needed See an example →

Free tier includes 5 documents and 10,000 rows. No credit card required.

1 · The living sheet

customers (Excel or Airtable)

id  name     plan
1   Acme     pro
2   Globex   starter

Stays connected: edits in the sheet flow into the table, and API writes can flow back.

2 · The PDFs beside it

invoices (extracted by AI)

number  customer_id  total   status
1001    1            $4,200  paid
1002    2            $1,150  due

Columns, types, and keys are detected for you. Link customer_id → customers.id in one click.

3 · Ask across both

From Claude, Cursor, or your app

"Which pro customers have unpaid invoices?"

Your agent calls the MCP tools query_table and related_rows over the linked tables. Apps get the same data with ?include=customer_id on REST.

Call the live API with the public demo key

A read-only workspace with the example customers and invoices above, already linked.

curl "https://docquery.io/api/v1/tables/example_invoices/rows?include=customer_id" \
  -H "Authorization: Bearer dq_demo_readonly"

Same key works for MCP at /api/v1/mcp (setup). More calls are on the API quickstart. Your own workspace gets a private key with full read/write.

Not just a sheet-to-API.

Plain spreadsheet-to-JSON tools give you one flat table. Inbox parsers give you fields from one PDF at a time. The useful answers are in between: which contract goes with which customer, which invoice belongs to which project.

• Spreadsheets and documents in one workspace, with real foreign keys between them.
• Live sync with Excel (Microsoft 365), Google Sheets imports, and Airtable.
• The same data over REST (OpenAPI), GraphQL, and an MCP server for agents.
• Export any table to CSV or JSON. Your data never gets stuck here either.

1. 1

   Upload or connect

   Drop in a CSV, JSON, Markdown, PDF, DOCX, or PPTX — or connect Airtable, Google Sheets, or Microsoft 365 with OAuth.
2. 2

   Extract

   AI detects tables, columns, types, and primary keys. You review and tweak.
3. 3

   Relate

   Link columns across tables with foreign keys — no SQL, no migrations.
4. 4

   Ship

   REST, GraphQL, and MCP endpoints are live the moment you save.

For apps + integrations

CRUD endpoints per table with filter, pagination, and relation expansion via ?include=. Auto-generated OpenAPI spec.

GET /api/v1/tables/invoices/rows?status=paid&include=customer_id

For flexible queries

Workspace-aware schema with nested relations. Filter, paginate, and traverse foreign keys in a single request.

{ rows(table: "invoices") {
  data
  related(column: "customer_id") {
    data
  }
} }

For AI agents

Native Model Context Protocol — Claude, Cursor, and any MCP-aware client gets tools, resources, and prompts out of the box.

POST /api/v1/mcp
{"method":"tools/call",
 "params":{"name":"query_table",...}}
