What the code does

We read the source, 10 h ago · tools taken from the live server · rules 995398eba69f

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

For retrieval (english rag), the current pick is <strong>Voyage voyage-4-lite</strong>  (score 73.2).

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

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.

categories
list_categories
List every vendor category VendorIndex covers (e.g. transactional-email, llm-models, embeddings-apis, llm-gateways), each with its use cases and vendor count. Call this first to discover valid category and use_case ids.
category
get_category_ranking
Get the ranked vendors for a category, scored per use case (deterministic, from verified pricing + agent-friction + health). Omit use_case to get the ranking for every use case in the category. Returns each vendor's weighted total and per-dimension scores.
compare
compare_vendors
Side-by-side comparison of several vendors for one category + use case: weighted totals, per-dimension scores and health trend. Use for head-to-head questions.
recommend
recommend
Recommend the top vendors for a specific category + use case, with the reasoning (which dimensions drove the pick). Best when an agent needs a single answer to 'what should I use for X?'.
vendor
get_vendor
Full detail for one vendor: cited pricing (structured rates + source URL + verified date + confidence), agent-friction checks, SDKs, capabilities, portability and health signals.
vendors
search_vendors
Find vendors by free-text query across name, id, category and capability (e.g. 'embedding', 'soc2', 'fast_inference'). Returns matches with their categories.

VendorIndex — questions

Answers built from our own checks of this server.

What can VendorIndex do?
It exposes 6 tools, read directly from the server on our last check. Among them: compare_vendors, get_category_ranking, get_vendor, list_categories, recommend, search_vendors. 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 VendorIndex working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 137 ms. The bar chart above shows every period we have measured.
How do I connect VendorIndex?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does VendorIndex need an API key?
No. VendorIndex 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.
How fast is VendorIndex?
It answers our handshake in 137 ms on average, which is faster than 85% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is VendorIndex open source?
The code is open source: it is published under the MIT licence, written in HTML and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at mcp.vendorindex.dev, which runs on its operator's own terms.
