Read mailboxes, documents and parsed data; parse text and re-parse documents in Parsio. For teams that pull data out of emails, PDFs and other documents with Parsio. Hosted by usefulapi — connect from Claude, ChatGPT, Cursor, or any MCP client.
Team and Enterprise: an Owner adds the connector for the organization first.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"parsio": {
"url": "https://parsio.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"parsio": {
"type": "http",
"url": "https://parsio.usefulapi.io/mcp"
}
}
}No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
Run these commands. The second one opens the login page:
Other MCP clients (Windsurf, Cline, Zed and more): add the URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser. Do not add an Authorization header: see Before you connect.
List the mailboxes and open the parsed data of recent documents. Check that the extracted fields are right.
parsio_list_mailboxes parsio_list_documents parsio_get_parsed_data
Read the table fields and the templates of a mailbox to see what the parser extracts.
parsio_list_table_fields parsio_list_templates parsio_get_template
Send a text or HTML sample to a mailbox and read the extracted result. Use it to test a template before real mail arrives.
Changes data · parsio_parse_text
Find the document that failed. Then parse it again so the new template applies.
Changes data · parsio_list_documents parsio_get_document parsio_reparse_document
List the webhooks of a mailbox and the emails it collected.
parsio_list_webhooks parsio_list_collected_emails
The login page asks for your Parsio API key.
Find it in Parsio → Account settings (API key). Your key is used only to call the API on your behalf and to derive a private account id; it is never shown to anyone.
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 Parsio 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.
Turn on the Parsio connector, then ask in plain words. The AI picks the tools.
| Tool | Type | What it does |
|---|---|---|
parsio_list_mailboxes | read | List mailboxes List all Parsio mailboxes (inboxes that hold documents and parsers) available to the account. Good first call to find a mailbox id. API: GET /mailboxes/. |
parsio_get_mailbox | read | Get a mailbox Get one mailbox with its settings: name, parser type (preset), model and email address. API: GET /mailboxes/{id}. |
parsio_list_table_fields | read | List table fields List the table fields defined in a mailbox (the column names of its parsed tables). API: GET /mailboxes/{id}/tableFields. |
parsio_list_documents | read | List documents List documents in a mailbox, newest first, with status. Filter by date range, name search or status. Paginated (per_page max 500). API: GET /mailboxes/{id}/docs. |
parsio_get_document | read | Get a document Get a parsed document as JSON, with its status and extracted fields. Use it to fetch a result after parsing_in_progress was true. API: GET /docs/{id}. |
parsio_get_parsed_data | read | Get parsed data Get the parsed data of documents in a mailbox, optionally for a date range. Paginated. API: GET /mailboxes/{id}/parsed. |
parsio_list_templates | read | List templates List the parsing templates of a template-based mailbox. Paginated. API: GET /mailboxes/{id}/templates. |
parsio_get_template | read | Get a template Get one parsing template with its rules. API: GET /templates/{id}. |
parsio_list_webhooks | read | List webhooks List the webhooks of a mailbox (url, event, enabled). API: GET /webhooks/mb/{mailbox_id}. |
parsio_list_collected_emails | read | List collected emails List the sender email addresses a mailbox collected. API: GET /mailboxes/{id}/emails. |
parsio_parse_text | write | Parse text or HTML WRITE: create a new document in a mailbox from plain text or HTML and wait for the parsed result. It counts against the account's Parsio document quota. Works only for template-based and GPT-powered mailboxes. If it returns parsing_in_progress true, fetch the result later with parsio_get_document. API: POST /mailboxes/{id}/doc-sync. |
parsio_reparse_document | write | Parse a document again WRITE: queue an existing document for parsing again, for example after you change a template. The old result is replaced. API: POST /docs/{id}/parse. |
parsio_usage_status | Usage status (free-tier meter) 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. | |
parsio_request_feature | Request a missing feature Tell usefulapi that the user needs something the Parsio 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. | |
parsio_upgrade | Upgrade to Pro (unlimited*) Get Pro: unlimited tool calls (fair use limit: 10,000 a month) on Parsio (the free tier caps monthly usage). Plans: "monthly" — $9/month; "yearly" — $90/year (2 months free). Cancel any time: Pro then runs to the end of the paid period, so it also suits a one-time job. *A fair use limit applies. For heavy use (near Pro's limit): "plus" or "plus_yearly" — Pro+, $39/month or $390/year, unlimited tool calls (fair use limit: 100,000 a month); an existing Pro subscription changes to Pro+ in place (needs confirm: true; the price difference for the rest of the period is charged at once). Otherwise returns a short link to open in your browser (it opens Stripe Checkout); after payment the account upgrades automatically. Does not count against the meter. | |
parsio_cancel_subscription | Cancel the Pro subscription Cancel the caller's Parsio 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 parsio_upgrade later to undo the cancel before the period ends. Does not count against the meter. |
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper user | $9/mo · $90/yr | Unlimited* |
*Pro fair use limit: 10,000 tool calls a month on this server. For more, write to [email protected].
Pro covers this Parsio server only. Subscribe with parsio_upgrade (it returns a Stripe Checkout link). Cancel any time with parsio_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running parsio_upgrade before then undoes the cancel. Or write to [email protected].
Review the parsed data of a mailbox. Check the table fields and templates of a mailbox. Test a template on sample text. Parse a document again after a template change. Check which webhooks and senders a mailbox uses. See what you can do for the details.
No. usefulapi is an independent service. It is not affiliated with or endorsed by Parsio. The server calls the Parsio API with your own Parsio access, so it sees only the data that your account can see.
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.
The login page asks for your Parsio API key. See Before you connect for where to find it.
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 Parsio 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.
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Parsio 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 Parsio.
Yes, if you approve it. 2 of the 12 Parsio tools can create or change data. The other 10 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with unlimited tool calls (fair use limit: 10,000 tool calls a month), for this Parsio server only. Cancel any time: Pro then runs to the end of the paid period. Run parsio_usage_status to see how many calls you used.
Ask the AI to run parsio_upgrade: it returns a Stripe Checkout link. To cancel, run parsio_cancel_subscription. Pro continues to the end of the paid period.
Tell the AI what you wanted to do. It can send the request with parsio_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.
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.
