About MCP-Recall
MCP-Recall is an open-source developer tool designed to solve context window bloat in heavy Model Context Protocol (MCP) workflows. By automatically compressing tool outputs—reducing payloads like 94 KB down to just 3.5 KB (a ~96% reduction)—MCP-Recall prevents tool responses from overflowing your LLM session context.
Instead of discarding full response data, MCP-Recall persists the complete, uncompressed tool outputs into an SQLite database for subsequent retrieval when needed. This architecture enables developers and AI agents to handle up to 30x more tool calls per session during resource-intensive tasks. Created by Jonathan Tomek, the project is open-source and accessible via GitHub and NPM.
Pros of MCP-Recall
- Compresses tool output sizes by up to 96% (e.g., 94 KB down to 3.5 KB)
- Stores raw, uncompressed response data in SQLite for future retrieval
- Enables up to 30x more tool calls per session for heavy MCP workloads
- Open-source developer tool available on GitHub and NPM
Cons of MCP-Recall
- Designed specifically for Model Context Protocol (MCP) environments
- Requires managing database retrieval when full output details are needed
- Currently lacks extensive community reviews or user ratings
Frequently Asked Questions
What is MCP-Recall?
MCP-Recall is an open-source tool for developers working with the Model Context Protocol (MCP). It compresses tool outputs to save context window space and persists full response data to SQLite for retrieval.
How does MCP-Recall save context space?
It compresses large output payloads—achieving reductions of around 96% (such as scaling 94 KB down to 3.5 KB)—allowing your session context to stay lean while saving full outputs in a local database.
How many tool calls can I run using MCP-Recall?
By dramatically reducing context consumption per response, MCP-Recall allows heavy MCP workloads to execute up to 30x more tool calls within a single session.
Where can I find and install MCP-Recall?
MCP-Recall is available as an open-source repository on GitHub and can be installed via NPM.
About Vizhi
Vizhi (named after the Tamil word for 'eye') is an open-source hardware mission control interface engineered for developers managing concurrent AI coding sessions. Created by indie developer Ravi Shankar during OpenAI Build Week, Vizhi addresses a modern workflow bottleneck: as autonomous coding assistants handle the bulk of software generation, developer attention shifts towards monitoring, approving, and steering multiple terminal processes. Vizhi maps these supervisory tasks directly onto physical hardware via the Logitech MX Creative Keypad, turning its dynamic LCD keys into a dedicated command deck. The system tracks up to six active Codex CLI sessions simultaneously across macOS terminal tabs, binding each session to a persistent LCD key showing its live status and context consumption. When an AI agent reaches a permission checkpoint or command execution gate, the corresponding key lights up in amber or red, enabling instant, one-press approvals directly from the keypad without switching windows. Beyond physical controls, Vizhi integrates offline Whisper-based voice dictation to send spoken prompts straight to agents, backed by TTY-verified safety delivery. For developers without the physical Logitech keypad, Vizhi includes a local browser-based companion dashboard that mirrors session supervision entirely offline.
Pros of Vizhi
- Transforms physical keypad hardware into an intuitive, glanceable control deck for up to six simultaneous Codex CLI sessions
- One-touch hardware approval keys reduce window-switching fatigue during multi-agent workflows
- Completely local and private architecture with on-device Whisper transcription and token-protected TTY verification
- Includes a browser-based local dashboard fallback for developers without the Logitech MX keypad
- Open-source and highly customizable key-binding configuration
Cons of Vizhi
- Full hardware experience requires a specific peripheral (the Logitech MX Creative Keypad)
- Currently tailored specifically to macOS and Apple Terminal environments
- Requires manual local setup spanning multiple toolchain components
Frequently Asked Questions
What is Vizhi and how does it help developers?
Vizhi is an open-source supervisor dashboard that connects Codex CLI agent sessions to the Logitech MX Creative Keypad, allowing developers to monitor active sessions, approve terminal actions with one press, and issue voice prompts.
Do I need a Logitech MX Creative Keypad to use Vizhi?
No. While the system is optimized for the physical LCD keys of the Logitech MX Creative Keypad, Vizhi includes a local browser dashboard that provides full session monitoring and controls on your computer screen.
How does voice prompting work in Vizhi?
Vizhi features a dedicated Voice key powered by local Whisper transcription. Spoken instructions are transcribed on-device without cloud API dependencies and sent directly to the targeted agent terminal.
Is Vizhi safe to use for terminal command approvals?
Yes. Vizhi runs entirely on your local machine and uses token-protected, TTY-verified approval delivery with visual color-coded badges to guard against unauthorized or accidental command executions.
