## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 46/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 6 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 67/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 444 tokens (~74/item across 6 items; 6 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 7/100
  - Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 67/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## Install

### How do I install the VendorIndex MCP server?

VendorIndex is a hosted endpoint at https://mcp.vendorindex.dev/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

### Claude

claude mcp add --transport http andy-chak-vendorindex 'https://mcp.vendorindex.dev/mcp'
```

```json
{
  "mcpServers": {
    "andy-chak-vendorindex": {
      "url": "https://mcp.vendorindex.dev/mcp"
    }
  }
}
```

### VS Code

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-11-04 (score 55, +1)

- [functional improvement] Stability: unverified → 0.03

### 2026-11-03 (score 54)

First indexed and scored.

## MCP tools (6)

### `list_categories` (~58 tokens)

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.

### `get_category_ranking` (~80 tokens)

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.

Input parameters:

- `category` (string, required)
- `use_case` (string)

### `recommend` (~69 tokens)

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?'.

Input parameters:

- `category` (string, required)
- `limit` (integer)
- `use_case` (string, required)

### `get_vendor` (~50 tokens)

Full detail for one vendor: cited pricing (structured rates + source URL + verified date + confidence), agent-friction checks, SDKs, capabilities, portability and health signals.

Input parameters:

- `vendor` (string, required)

### `compare_vendors` (~63 tokens)

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.

Input parameters:

- `category` (string, required)
- `use_case` (string, required)
- `vendors` (array, required)

### `search_vendors` (~52 tokens)

Find vendors by free-text query across name, id, category and capability (e.g. 'embedding', 'soc2', 'fast_inference'). Returns matches with their categories.

Input parameters:

- `query` (string, required)

## Common questions

### What is the VendorIndex MCP server?

VendorIndex is an MCP server listed in the public MCP registry as io.github.andy-chak/vendorindex. Rank vendors/libraries per use case from verified pricing, agent-friction and health. This page covers its hosted endpoint (https://mcp.vendorindex.dev/mcp).

### Is the VendorIndex MCP server safe to use?

VendorIndex scores 55 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the VendorIndex MCP server expose?

VendorIndex exposes 6 tools: list_categories, get_category_ranking, recommend, get_vendor, compare_vendors, search_vendors. Their descriptions and schemas cost roughly 372 tokens of context every time the server is loaded.

### Does the VendorIndex MCP server require authentication?

No. We connected to VendorIndex without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the VendorIndex MCP server still maintained?

VendorIndex is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
