4. Connect your Parsio account

Back in Cowork, ask the agent to connect to Parsio or give it any Parsio-related task.

For example, ask Cowork to:

  • "Extract invoice totals from new PDFs"
  • "Parse email orders into structured records"
  • "List recently parsed receipts by vendor"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Cowork, and your Parsio account is ready to use.

What is Claude Cowork?

Claude Cowork is Anthropic's agent for general knowledge work. It can use your computer, files, and connected applications to complete longer-running tasks across your work tools.

With Composio Connect, Cowork can securely access apps like Parsio through MCP without you sharing account credentials directly with the agent.

What is the Parsio MCP server, and what's possible with it?

The Parsio MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Parsio account. It provides structured and secure access to your mailboxes, documents, and extraction fields, so your agent can submit content for parsing, retrieve extracted data, manage documents, and update mailbox settings on your behalf.

  • Document parsing and extraction: Have your agent submit plain text, HTML, or files to a configured mailbox and return the extracted information.
  • Parsed document retrieval: Instruct your agent to find documents in a mailbox and retrieve their parsed fields for review or further work.
  • Mailbox and field discovery: Let the agent list your available mailboxes, inspect their parser settings, and view the extraction fields configured for each one.
  • Document reprocessing and cleanup: Direct your agent to reparse existing documents when extraction rules change or mark selected documents as skipped.
  • Mailbox configuration updates: Have your agent review and update settings for an existing Parsio mailbox.

FAQ

Frequently asked questions

With a standalone Parsio MCP server, the agents and LLMs can only access a fixed set of Parsio tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Parsio and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Parsio tools.

Yes, absolutely. You can configure which Parsio scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Parsio data and credentials are handled as safely as possible.
