The toolset

4 MCP actions QUILL can call.

Every action is exposed as an MCP server (Model Context Protocol). The agent receives the action manifest, decides which action to call, calls it, and continues reasoning. The audit trail records every call.

  • mcp.xlsx.read

    Read XLSX preserving formulas + formatting

  • mcp.xlsx.write

    Write XLSX preserving structure

  • mcp.xlsx.reconcile

    Reconcile two XLSX files

  • mcp.xlsx.audit

    Audit XLSX for errors

The memory schema

What QUILL remembers between calls.

  • The XLSX schema
  • The reconciliation rules
  • The audit results
