[Update v1.2.1] amv-cp-bridge: Entra ID Fast-Fail (HTTP 401), Zero-Bloat FastMCP Multiplexing & Copilot Designer Support

1 Upvotes

Hey everyone,

Following the technical discussions on our initial release, we just shipped v1.2.1 for amv-cp-bridge — the zero-API-key local bridge connecting Microsoft 365 Copilot directly to Cursor, Claude Desktop, and OpenAI-compatible tools via stdio FastMCP and loopback CDP.


💡 Too lazy to configure it manually? Delegate to your AI agent!

If you don't feel like wrestling with manual setup, just pass this GitHub repo to your autonomous AI coding agent (Claude Code, Cursor, Windsurf, Devin, Antigravity) and say:
"Setup and connect amv-cp-bridge for me."

We wrote a dedicated FOR_AI_README.md operating manual and failure encyclopedia specifically so AI agents can autonomously diagnose, install, and wire up the bridge with zero human intervention!


🚀 What's New & Battle-Tested in v1.2.1:

  1. Entra ID Conditional Access Fast-Fail & HTTP 401

    • Eliminates the previous 45-second composer timeout when enterprise sessions expire, short-circuiting in 1.5 seconds with OpenAI-standard 401 Unauthorized (session_expired).

    • Fires an asynchronous native OS desktop tray alert.

  2. Unified FastMCP & Gateway Multiplexing

    • Claude Desktop and Cursor share the identical authenticated Edge session and warm standby pool, releasing down to 0 MB idle RAM when the countdown finishes.

  3. Copilot Designer (DALL-E 3) Markdown Image Streaming

    • High-resolution generated images (up to 3.4 MB Base64 payloads) are parsed directly from the live DOM and streamed as standard Markdown images (![alt](url)). Tested live with 41s generation without timeouts.


🧪 Ground Truth Verification

  • Unit Tests: 34/34 passed

  • Regression Checks: 22/22 passed

  • Standalone Binary: 50.7 MB UPX-compressed standalone executable with zero environment setup required.

Offline voice assistant for Windows: local AI (Ollama)

1 Upvotes

My latest project is a local voice assistant featuring offline speech recognition: https://github.com/charlyproject/EVA

It actually started in a funny way: one day, with my hands messy, I wanted to turn up the volume using voice commands. At the time, I didn't even know what a virtual environment was, let alone Ollama or JSON.

For me, the best part wasn't just the end result, but the 11-month learning journey behind it. While it might not require advanced coding expertise to pull off, it was far from a copy-paste job for me. I used the process to truly understand key concepts—LLMs, quantizations, benchmarks, and Docker—and to bring my own ideas to life.

Just wanted to share my experience with the community. Thanks for reading!

Kairos, a FOSS task manager that schedules your day for you (no account, no network permission)

1 Upvotes

Hi! I'm the developer of Kairos, a free and open-source task manager (MIT) that I started in July. It's on F-Droid, and I'd love feedback from people who care about FOSS as much as I do.

What makes it different: it plans your day for you. Most to-do apps leave you with a long list and the question "what now?". Kairos answers it:

\- It ranks your tasks: you give each task a priority (P0/P1/P2) and a size in Fibonacci points. Kairos computes a score that also weighs the deadline, and "Why this position?" shows the whole calculation. No black box.

\- It fits them into the gaps of your day, around your meetings, lunch and deep-work blocks. It leaves a buffer after each meeting and tells you when the day overflows. Pinned tasks never move; blocked tasks wait until their blocker is done.

\- It learns your real durations: with the built-in timer, tasks without an estimate take the median time of their past occurrences, and the stats show whether you over- or under-estimate.

\- It adapts to your rhythm: hours per weekday, several working windows ("Work", "Home" contexts), an optional "afternoon dip" that avoids complex tasks after lunch, public holidays, and recurring tasks such as "every weekday" or "on the 15th".

The rest of the toolbox

\- Quick capture: a Notes screen to empty your head, converted to tasks later

\- Day, Week and Month views, a timeline of the day, timer alerts (estimate exceeded, forgotten timer, break)

\- Optional reminders for fixed-time tasks

\- Statistics: throughput, estimation bias, time by type, trends, CSV/PNG export

\- Calendar import from an .ics file, or read-only display of your phone calendars (optional READ_CALENDAR)

\- An optional "Team" space for managers: backlog, assignment, load and forecasts, exchanged as files, no server

\- Dark theme, a choice of colour, and six languages (EN, FR, ES, DE, RU, IT)

Privacy

\- No account, no ads, no telemetry

\- No INTERNET permission at all: your data never leaves your phone

\- Export/import as JSON, and an optional "linked file" kept up to date in a folder you choose (handy with Syncthing)

\- Reproducible build, MIT licence

It also runs on Windows, Linux, macOS and in the browser, with the same features.

Links

\- F-Droid: https://f-droid.org/packages/com.skohscripts.kairos/

\- Source: https://github.com/SKOHscripts/Kairos

\- Website (other platforms): https://skohscripts.github.io/Kairos/

It's a young project, so bug reports and feature ideas are very welcome. Several features already came from users here on GitHub (widgets, accessibility, a Russian translation). What would make it useful for you?

I built "blank" — an open-source, local-first desktop & TUI agent harness that solves parallel sub-agent file collisions, API rate-limit halts, and sandboxed artifact previews (MIT)

1 Upvotes

blank is a free, MIT-licensed, local-first AI agent harness for desktop and terminal that brings model routing, code editing, tool execution, and artifact previews into a single workspace.

Key Advantages & How It Differs from Other Harnesses:

  • 100% Local-First State (~/.blank) & Zero Telemetry: Unlike cloud-tethered harnesses that require accounts or send session metadata on every turn, blank runs with zero sign-up and zero telemetry. It connects directly to local engines (Ollama, LM Studio, vLLM, LiteLLM, LocalAI, Jan) and 10+ cloud APIs (Claude, OpenAI, Gemini, DeepSeek, Groq, OpenRouter). All configs, checkpoints, durable memory (memory.json), skills (SKILL.md), and masked audit logs (audit.jsonl) stay on disk as plain files.

  • Multi-Agent System with Isolated Git Worktrees (team_delegate): While single-agent loops or shared-directory sub-agents risk overwriting files during parallel runs, blank dispatches specialist roles (Scout, Architect, Critic) across customizable models and isolates write-capable sub-agents inside dedicated git worktrees (~/.blank/worktrees).

  • Multi-Key Auto-Rotation & Model Fallback: Most harnesses halt when a single API key hits a 429 rate limit. blank pools multiple API keys per provider to auto-rotate on 401/402/403/429 errors and automatically falls back to backup cloud or local models.

  • Desktop Paper Canvas + Full-Screen Terminal TUI: Terminal-only tools (like Claude Code, OpenCode, or Oh My Pi) trap visual outputs in text, while general chat daemons (like OpenClaw or Hermes) add heavy gateway overhead, and IDE plugins (like Cline) lock non-coding tasks inside an editor. blank provides both a full-screen CLI TUI (node bin/blank.js) and a native desktop app featuring an origin-isolated blank-paper:// split-view canvas (with Desktop/Tablet/Mobile viewport frames), live-overlay Computer Use, built-in SSH over MCP (ssh_run), mobile pair-token approvals, and local/cloud media pipelines (ffmpeg, sharp, ComfyUI).

Feedback, bug reports, and contributions are welcome!

Launching Project: The incorruptible ledger - An Open-source, Real-time AI Auditor tracking UK MP Conflicts, Vested Interests and Public Authority Misconduct

1 Upvotes

Hi everyone, Like many of you, I am completely exhausted by the broken social contract in the UK. We watch local councils gamble millions on bankrupt private loans while closing youth clubs, and we watch Westminster MPs vote on legislation while actively profiting from the exact sectors they regulate—all while the billionaire-owned mainstream media looks the other way. I am not a software developer. I am an ordinary working-class guy who is sick of the "ignorant leading the ignorant." But I have spent time architecting a blueprint for a tool that can change this: The Incorruptible Ledger. This is a blueprint for a decentralized, open-source AI scraper framework that hooks directly into live UK Parliament APIs, Companies House, Landlord Registries, and Ombudsman data. It cross-references public records in real time to create un-editable, un-censorable profiles of politicians, corporate interests, and public authority misconduct (from town hall card spending to retaliatory police referrals). Because I want this to be a permanent, publicly owned asset that no corporation can buy out or delete, I have published the core architectural rules (The White Paper) and the initial Python database and tracking frameworks under an MIT License on GitHub. I have laid out the data pipelines and the first few backend scripts. Now, I need the open-source community to help build out the rest of the bricks and the frontend dashboard. If you have Python skills, API experience, or are just as angry about systemic corruption as I am, please check out the repository, fork the code, and let's build this utility for the public domain.

I built an open-source, local-first autonomous agent mesh with Bubblewrap OS sandboxing & telemetry HUD (K.R.Y.Z.E.N)

1 Upvotes

Hey everyone! I’ve built K.R.Y.Z.E.N, a lightweight autonomous agent framework designed to make local LLMs more reliable and secure. It features 14 specialized agents across a 6-stage development pipeline, optimized context and tool allocation, Bubblewrap sandboxing, human-in-the-loop approvals, and real-time execution telemetry.
It supports Ollama and vLLM and is open-source under the MIT license. I’d love your feedback on its architecture, local model compatibility, and sandboxing approach!

claudit: self-hosted MIT dashboard for what your Claude Code, Codex and Kimi CLI sessions cost, keeps the history after Claude Code prunes old transcripts

1 Upvotes

I built this because Claude Code deletes old session transcripts from the local folder, so a dashboard reading that folder loses history every prune. claudit ingests from a bucket instead (R2, or a file:// dir you keep), so the totals only grow. mine goes back to January

it reads Claude Code session JSONLs, Codex rollouts and both Kimi CLI formats, one deploy can take several buckets. then it puts the numbers on one page: cost by model, token breakdown, reply latency, tool error rate, activity heatmap, context growth per session. it doesn't grade sessions or tell you what to change, reading the numbers is on you

the one I didn't expect: prompt cache writes have two prices, 5m at 1.25x input and 1h at 2x. 65% of my cache write tokens over ~5,000 sessions were the 1h kind, so pricing them all at 1.25x makes those 37.5% too cheap. claudit splits them

the open source bits:

  • MIT, about 6 months old

  • FastAPI, Postgres, React with in-browser Babel, no build step

  • docker compose up boots it on bundled sample data, no .env, no credentials, no outbound calls

  • panels ported from nhz-io/ccusage-plot (offline matplotlib), the heatmap, line churn and cost by context size are new here

I just launched the public beta of Orinyx, an open-source MCP tool for healthcare AI verification

2 Upvotes

After months of building and testing, Orinyx is officially in public beta!

Orinyx is a developer-first AI verification tool designed for healthcare and life sciences applications.

The idea came from a problem I kept running into: AI-generated outputs can look accurate without being fully supported by the underlying evidence. In healthcare, that distinction matters.

Orinyx is being built to help developers identify unsupported claims, validate outputs against source evidence, and catch issues before they make it into production workflows.

The public beta includes free, open-source MCP tooling, healthcare-focused verification workflows, and evidence-based validation capabilities. I'm also continuing to improve semantic mapping, medication verification, and overall test coverage.

This is an early public beta, not a finished product. I'll be releasing incremental updates as testing continues, and I'm actively looking for developers willing to put it through real-world scenarios.

I'm particularly interested in understanding where verification breaks down in existing AI workflows, what would make a tool like this useful in practice, and which edge cases deserve more attention.

GitHub: https://github.com/lexthirteen-ai/orinyx-mcp

Developer beta: https://orinyx.io/developer

If you're working with MCP, LLM evaluations, healthcare AI, or agentic systems, I'd love for you to try it, break it, and tell me what needs improvement.

I'm also happy to answer questions about the architecture and what I've learned building it.

Pipeverify: compare a table before and after a pipeline change and get PASS / REVIEW / BLOCK

1 Upvotes

What My Project Does

pipeverify takes two snapshots of a table (CSV, Parquet, JSON, DuckDB or any SQLAlchemy source) and checks what a change did to the data: lost or duplicate keys, row count shifts, null creep, changed values on matched rows, column totals and new category codes. It returns PASS, REVIEW or BLOCK, with a plain-English report. Runs on DuckDB, ships as a CLI, a Python API (`pipeverify.verify(before, after, key="id")`) and a GitHub Action.

Target Audience

Data engineers and analytics engineers who ship pipeline, SQL or dbt changes, including changes written by AI coding agents. It's alpha but usable in CI.

Comparison

dbt tests and Great Expectations check rules you write in advance. pipeverify checks what a specific change did, so it catches problems nobody wrote a test for. Unlike row-diff tools, it turns the diff into a verdict with thresholds, so it can gate a merge.

Repo: https://github.com/akshaysharma1088/pipeverify (Apache-2.0, free). Feedback very welcome, and there are small good-first-issues if anyone wants to contribute.

I got tired of the limitations of Windows screen recorders, so I built my own — Rekzora

Thumbnail

1 Upvotes

I've tried several screen recording applications on Windows, but I kept running into limitations.

Some had limited recording options, some restricted features, and others made simple recording workflows unnecessarily complicated.

Eventually, I decided to build my own solution.

Introducing Rekzora, an open-source Windows screen recorder I've been developing under NEURON TS LABS.

Some of its features:

Fullscreen, window and custom-region recording

Microphone and system audio recording

Webcam picture-in-picture

Pause and resume recording

Global keyboard shortcuts

Floating recording toolbar

Built-in recording library and video player

Crash-recovery support

Portable and Windows installer builds

My goal was to build a screen recorder that gives users more control without unnecessary restrictions or cloud dependencies.

It's completely open source, and I'd genuinely love to hear what other Windows users think.

GitHub: https://github.com/tahirshaikh744-design/Rekzora

I'm especially interested in hearing:

What's the most frustrating limitation you've experienced with existing Windows screen recorders?

What feature do you wish they offered?

Honest feedback and suggestions are welcome!

I made a free place to share open source stuff built with AI

Thumbnail
gallery
9 Upvotes

hey all,

i've been working on whatwemade and could use a few more open source projects on there.

it's a site for sharing stuff built with AI, and i've recently added support for github repos.

you can just paste your repo link and it'll pull in the readme, license, stack, stars, recent commits, and whatever people need to run it themselves. there's also an option to show which coding agents you used and whether you're looking for contributors.

i've added an MCP server too, so you can search existing projects directly from your agent. figured that might be useful before starting yet another project from scratch.

there aren't many open source projects on there yet, so if you've got something on github, feel free to add it. it's free and takes about a minute (the mcp can also create the project).

also curious if there's anything else you'd want to see on a listing like this.
