What you can do with Docparser in Claude and ChatGPT

For finance and operations teams who extract data from invoices and other documents with Docparser.

See which parsers you have set up

The AI lists the document parsers of the account and the model layouts of one parser.

Read the parsed data of recent documents

The AI lists the parsed data of the last uploaded documents of a parser, or of those processed after a date, and opens one for its fields and tables.

Check if a document finished processing

The AI reads a document's status: importing or processing, page count, timestamps and failed jobs.

Import a document from a URL or upload one

The AI sends a document to a parser, either from a public URL or as a small base64 file, and then checks its status.

Changes data

Re-parse documents after changing the rules

The AI runs a parser again over documents that are already imported, so their parsed data is replaced with the new result.

How do I connect Docparser?

Before you connect

The login page asks for your Docparser secret API key.

Find it in Docparser under Account → API Settings. The key gives access to all parsers of the account; it is used only to call the Docparser API on your behalf and is never shown to anyone.

Claude claude.ai · Desktop

  1. Open Customize → Connectors, then click + Add → Add custom connector.
  2. Enter the name Docparser and this URL, then click Add:
    https://docparser.usefulapi.io/mcp
  3. Claude opens the login page: enter your Docparser secret API key.
  4. In a chat, click + → Connectors and turn on Docparser.

Team and Enterprise: an Owner adds the connector for the organization first.

ChatGPT chatgpt.com

  1. Open Plugins, click +, then Add custom MCP server.
  2. Enter the name Docparser and this URL, choose OAuth as the authentication, confirm the warning and create it:
    https://docparser.usefulapi.io/mcp
  3. ChatGPT opens the login page: enter your Docparser secret API key.
  4. In Plugins, install Docparser, then choose it in a chat.

No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.

Claude Code

Run this command, then run /mcp in Claude Code to log in:

claude mcp add --transport http docparser https://docparser.usefulapi.io/mcp

Cursor

Add to Cursor or add this to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "docparser": {
      "url": "https://docparser.usefulapi.io/mcp"
    }
  }
}

VS Code

Add to VS Code or add this to .vscode/mcp.json:

{
  "servers": {
    "docparser": {
      "type": "http",
      "url": "https://docparser.usefulapi.io/mcp"
    }
  }
}

Codex

Run these commands. The second one opens the login page:

codex mcp add docparser --url https://docparser.usefulapi.io/mcp
codex mcp login docparser

Other clients

Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.

https://docparser.usefulapi.io/mcp

Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Docparser secret API key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

Each paid plan covers this Docparser server only. Ask your AI to run docparser_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with docparser_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with docparser_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

  • Check API keydocparser_ping
    Check that the connected Docparser API key works. Returns {msg: "pong"} when it does.
  • List parsersdocparser_list_parsers
    List all Document Parsers on the account (id and label). Start here: the parser id is needed by every other tool.
  • List parser model layoutsdocparser_list_parser_models
    List the model layouts of one parser (id and label).
  • Get document statusdocparser_get_document_status
    Processing status of one document: importing/processing flags, page count, timestamps (uploaded, imported, processed), webhook dispatch and failed jobs. Poll this after a fetch/upload: the document is done when importing_in_progress and processing_in_progress are false, processed_at is set and failed_jobs is empty (a non-empty failed_jobs means it failed); then read the results.
  • Get parsed data of one documentdocparser_get_document_results
    The parsed data of one document (the fields and tables the parser extracted, plus file name, page count and upload/processing times). Docparser allows 60 of these calls per minute.
  • List parsed data of many documentsdocparser_list_document_results
    Parsed data of several documents of one parser: the last uploaded ones (default), or those uploaded/processed after a date. Returns up to 100 documents per call; page with offset (next_offset is null on the last page). Docparser allows 30 of these calls per minute.

  • Import a document from a URLdocparser_fetch_document_from_url
    WRITE: ask Docparser to download a document from a publicly reachable URL and parse it with the given parser. Uses page credits of the account's plan (documents queue when credits run out). Docparser may buy extra credits by itself only if the account owner turned on automatic credit replenishment, or the account is on an annual plan that renews early when credits run out - check the Docparser billing settings first. This server never buys credits or changes the plan. Returns the new document_id: poll docparser_get_document_status, then read docparser_get_document_results.
  • Upload a document (base64)docparser_upload_document
    WRITE: upload one small file as base64 content to a parser and parse it. Uses page credits of the account's plan. Docparser may buy extra credits by itself only if the account owner turned on automatic credit replenishment, or the account is on an annual plan that renews early when credits run out - check the Docparser billing settings first. This server never buys credits or changes the plan. Files up to about 2.3 MB; use docparser_fetch_document_from_url for larger files. Returns the new document id and the remaining quota.
  • Re-parse documentsdocparser_reparse_documents
    WRITE: run the parser again over already imported documents (for example after changing parsing rules). Replaces their parsed data. Re-parsing documents already in the account does not use additional credits. 1-50 document ids per call.

Your usefulapi plan · 4

  • Usage status (free-tier meter)docparser_usage_status
    Report the caller's current usage: the plan, calls used this month, the limit of the plan (the free monthly cap or the Pro fair use limit), remaining, and whether the limit is reached. Read-only; does not count against the meter.
  • Request a missing featuredocparser_request_feature
    Tell usefulapi that the user needs something the Docparser tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter.
  • Upgrade to Pro or Pro+docparser_upgrade
    Get a paid plan for Docparser (the free tier caps monthly usage). Pro: 10,000 tool calls a month, for normal use — plan "monthly" ($9/month) or "yearly" ($90/year, 2 months free). Pro+: 100,000 tool calls a month, for automations and heavy use — plan "plus" ($39/month) or "plus_yearly" ($390/year). Without a plan it returns both Pro and Pro+, each with a payment link, for the user to choose; with a plan, one link. An existing Pro subscription changes to Pro+ in place: call without confirm first, as the reply states the exact charge for this account (the price difference for the rest of the period, or in a free Pro trial the full Pro+ price, as the trial ends); then call with confirm: true. Cancel any time: the plan then runs to the end of the paid period, so it also suits a one-time job. A link opens Stripe Checkout in the browser; after payment the account upgrades automatically. Does not count against the meter.
  • Cancel the Pro subscriptiondocparser_cancel_subscription
    Cancel the caller's Docparser Pro subscription at the end of the paid period (no refund for the current period; Pro continues until then, then the free tier applies). Requires confirm: true. Run docparser_upgrade later to undo the cancel before the period ends. Does not count against the meter.

FAQ

What can I do with Docparser in Claude or ChatGPT?

See which parsers you have set up. Read the parsed data of recent documents. Check if a document finished processing. Import a document from a URL or upload one. Re-parse documents after changing the rules. See what you can do for the details.

Is this an official Docparser product?

No. usefulapi is an independent service. It is not affiliated with or endorsed by Docparser. The server calls the Docparser API with your own Docparser access, so it sees only the data that your account can see.

Can I connect Docparser to Claude or ChatGPT?

Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.

What do I need to connect?

The login page asks for your Docparser secret API key. See Before you connect for where to find it.

Do I put my Docparser key or an Authorization header in the client config?

No. Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Docparser secret API key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

How do you keep my Docparser credentials?

The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Docparser API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in Docparser.

Can the AI change my Docparser data?

Yes, if you approve it. 3 of the 9 Docparser tools can create or change data. The other 6 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.

What does it cost?

The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this Docparser server only. Cancel any time: your paid plan then runs to the end of the paid period. Run docparser_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run docparser_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run docparser_cancel_subscription. Your paid plan continues to the end of the paid period.

What if a Docparser tool that I need is missing?

Tell the AI what you wanted to do. It can send the request with docparser_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.

Which AI clients can I use?

Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.

This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.

Need a tool this server does not have, or a connection to another system? We build custom integrations and MCP servers.
