Ls Search does not always answer

Over the last week it answered 0.0% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Available tools 6

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

trace

trace_create_workspace

Create an isolated, disposable (ephemeral) vector-search workspace - your own sandboxed index/namespace for semantic retrieval and RAG. Prepays container time via x402 micropayment (USDC on Base, EIP-3009); no account, no signup. Call without x_payment to get the price + payment terms; with a signed x_payment it returns a one-time capability_token for the other tools.

trace_dispose_workspace

Dispose and permanently delete the workspace and its in-memory vector index/data (zero data retention); returns a cryptographically signed disposal receipt confirming the wipe.

trace_get_passage

Retrieve a single stored passage/document/item (content and metadata) from your workspace vector index by item id.

trace_get_usage

Get workspace usage and billing status for your disposable vector-search workspace: prepaid time/TTL remaining, total spend, ingest/search counts, and state.

trace_ingest_batch

Ingest and index documents, passages or text chunks into your workspace to build the searchable vector/embedding index for semantic search and RAG retrieval. Each document: {name, text OR content_b64, mime?}; supports text and binary (base64) content.

trace_search

Semantic vector search / similarity retrieval (nearest-neighbor, embedding-based) over your private disposable index - the core RAG retrieval call. Supports natural-language text queries, cross-modal text->image, and reverse-image search (image_b64). Returns ranked passages/hits with locators. Provide query OR image_b64.

Ls Search — questions

Answers built from our own checks of this server.

What can Ls Search do?

It exposes 6 tools, read directly from the server on our last check. Among them: trace_create_workspace, trace_dispose_workspace, trace_get_passage, trace_get_usage, trace_ingest_batch, trace_search. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Ls Search working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 92 checks got a reply (0.0%), average response time 21 ms. The bar chart above shows every period we have measured.

Is Ls Search still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

The registry lists Ls Search as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect Ls Search?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Ls Search need an API key?

No. Ls Search completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.
