Organization membership does not imply sole authorship. Editorial status is separate from releases, adoption, or production availability. ### AgroVoz Editorial status: Closed beta An AI agent on WhatsApp for farm management: it understands voice, text, and photos, records operations, and answers with per-farm memory. Includes a web dashboard. - 17 modules - 3 inputs: voice, text, and photo **Problem:** Recording farm operations in the field requires less typing and context preserved across messages. **Contribution:** Built the multimodal flow, intent interpretation, transcription, and semantic retrieval over farm data. **Public evidence:** Public surface at agrovoz.app; the product is publicly identified as a closed beta. - [App](https://agrovoz.app/) ### TranscreveAI Editorial status: Open source · alpha A multimodal pipeline that turns video and audio into indexed dossiers with evidence-backed answers, exposed as an MCP server. **Problem:** Long-form media reaches agents as an opaque file that is difficult to search, cite, and reuse. **Contribution:** Created the CLI and MCP capability combining transcription, frames, OCR, vision, indexing, and source-backed retrieval. **Public evidence:** Public code and documentation in the DeHor Labs repository; it is not presented as a production SaaS. - [GitHub](https://github.com/DeHor-Labs/transcreve-ai) ### MCP Fiscal Brasil Editorial status: Published on PyPI An open-source MCP server with 45 tools for Brazilian fiscal data and operations. Published on PyPI and in the official MCP registry under the MIT license. - 45 tools - MIT license - 46K impressions on the launch post - 769 LinkedIn reactions `uvx mcp-fiscal-brasil` **Problem:** Agents need access to Brazilian fiscal sources through clear contracts without coupling every client to each data source. **Contribution:** Fiscal XML parsing is separate from external queries: documents can be processed offline, while FastMCP exposes tools with typed contracts. **Public evidence:** Public NF-e example: test XML goes in; structured issuer, items, and totals come out without an external API. Code, documentation, and PyPI package are available.
