ComputerPilot MCP v0.6.0 - Cross-Platform Preview

ComputerPilot MCP v0.6.0 - Native Document Intelligence

ComputerPilot MCP v0.6.0 adds first-class native document adapters for Excel, DOCX, and PDF so common document work can be performed through structured MCP tools without launching desktop applications.

Highlights

Excel

• Add structured workbook inspection and sheet listing for .xlsx and safely supported .xlsm files.
• Add bounded range reads, value/formula search, formula inspection, and table metadata.
• Add guarded range writes/clears, sheet add/rename/delete, formula assignment, and table creation.
• Serialize same-file mutations while allowing independent workbooks to proceed concurrently.
• Support optional SHA-256 preconditions so stale external edits are rejected before mutation.
• Preserve XLSM VBA project bytes only when staged serialization verifies they remain byte-identical.
• Reject macro-bearing XLSX files and unsupported macro-loss scenarios instead of silently stripping content.
• Validate OOXML archive paths, duplicate members, encryption flags, CRC integrity, entry limits, expanded-size budgets, and excessive compression before OpenPyXL parsing.

DOCX

• Add structure and core-metadata inspection.
• Add bounded paragraph and table-cell reads plus bounded text search.
• Add conservative text replacement, paragraph insertion, simple table-cell replacement, and simple DOCX creation.
• Preserve supported run formatting and fail closed when a replacement crosses differently formatted runs.
• Validate DOCX ZIP structure, required members, traversal attempts, duplicate members, encryption, CRC failures, and decompression limits.
• Keep .docm, tracked changes, comments, headers/footers, and arbitrary WordprocessingML mutation explicitly unsupported.

PDF

• Add PDF page-count, encryption-state, and metadata inspection.
• Add bounded single-page and multi-page text extraction with explicit page/character limits and optional file-backed delivery.
• Add deterministic new-PDF creation from plain text and a documented Markdown subset.
• Reject encrypted PDF text extraction unless the caller provides a decrypted input.
• Keep arbitrary editing of existing PDFs outside the v0.6.0 contract.

Recovery and artifacts

• Return document artifact descriptors containing path, SHA-256, byte size, and media type.
• Use same-directory staging, format-specific round-trip validation, backups, and atomic publication for mutations.
• Durably checkpoint the expected final file hash before atomic replacement so a crash after the side effect can be reconciled without blind replay.
• Add a dedicated documents tool profile while preserving the existing full profile and typed tool catalog.

Dependencies

The native-document runtime uses mature format libraries recorded in the project runtime dependencies:

• OpenPyXL for Excel;
• python-docx for DOCX;
• pypdf for PDF inspection/extraction;
• ReportLab for deterministic PDF creation.

These dependencies are part of the normal portable runtime for v0.6.0.

Compatibility

v0.6.0 includes all v0.5.0 Semantic Browser capabilities.

The protocol-level MCP server identifier remains:

ali_windows_agent_mcp

Existing client and Secure Tunnel configurations therefore do not require an identifier migration.

The document domain is portable across supported Windows, Linux, and macOS hosts. Windows-only UI Automation remains capability-gated and is not required for native document operations.

Packaging contract

v0.6.0 continues deterministic packaging for:

• computerpilot-mcp-v0.6.0-windows-amd64.zip
• computerpilot-mcp-v0.6.0-linux-amd64.tar.gz
• computerpilot-mcp-v0.6.0-linux-arm64.tar.gz
• computerpilot-mcp-v0.6.0-macos-amd64.tar.gz
• computerpilot-mcp-v0.6.0-macos-arm64.tar.gz
• SHA256SUMS.txt

Linux arm64 and macOS amd64 remain deterministic package/updater targets without a dedicated native hosted-runner claim.
