MeiliSearch
A lightning-fast search engine API bringing AI-powered hybrid search to your sites and applications.
> Would Hister be suitable for this?
The indexer it uses (Bleve) can handle millions of records according to their docs, but sure that Hister would be the best choice for this task. I'd probably use Meilisearch (https://www.meilisearch.com/).
> Can it index mbox files?
Not yet.
> Does it have a search API so I can build an MCP server?
It has both search API and MCP server endpoints.

I've been on Ghostty for about 8 months. Last week I added herdr, a multiplexer built around running coding agents (Claude Code, Codex, opencode and friends) in panes. Ghostty already has tabs and splits, with Cmd shortcuts I use all day. herdr has its own tabs, panes and workspaces, with its own keys.

The incumbents in the semantic layer space are MetricFlow (dbt’s semantic layer engine) and Cube.js; worth mentioning is Lightdash, which used to be more of a dashboard solution but is now increasingly beefing up its semantic layer side. A project to watch is Apache Ossie (formerly Open Semantic Interchange), which aims to become an open source semantic layer standard. At the moment it only has a limited spec for specifying datasets and no reference semantics for querying, so definitely worth following but not a full solution at the moment. Finally, we will cover SLayer, a recent entrant aiming to be used by agents as well as humans.

Project mention: Cut token waste across your entire team with the MCP Optimizer | dev.to | 2026-03-11
The operator defaults to BAAI/bge-small-en-v1.5 as the model and runs the HuggingFace Text Embeddings Inference server. You can increase the replica count via spec.replicas to match your team's throughput needs. One shared instance serves every vMCP in the namespace. For all available configuration options, see the Optimizer docs.

agentos
Give agents an operating system as a library. Runs in your existing backend – no sandboxes, VMs, or SaaS. Powered by WebAssembly & V8 isolates. (by rivet-dev)
Their companion project AgentOS runs coding agents inside isolated Linux VMs with an in-process operating system kernel. Everything runs inside the kernel; nothing executes on the host. The pitch: faster, lighter, cheaper than mainstream sandbox providers.
