## 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**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - 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 (excellent).
  - Context-footprint check failed: tool/resource definitions use about 703 tokens (~351/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 33/100
  - Stability observed for 10 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% 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 2 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (2)

### `web_search` (~451 tokens)

Web search

Search the web and get a ranked list of results with title, URL, date and a short summary.

Use it when you need current or external information: recent events, documentation, prices, facts you are not sure about. Prefer one well-chosen query over many similar ones; if the summaries are not enough, call web_fetch on the most relevant URL instead of searching again.

Query rules:
\- At most 128 characters. Write concise keywords, not a long question.
\- Operators (combine freely):
  site:example.com      only results from that site
  \-site:example.com     exclude that site
  lang:en               results in a language (e.g. lang:zh, lang:en)
  after:2025-01-01      published on or after a date (YYYY-MM-DD)
  before:2025-12-31     published before a date
\- Example: "cloudflare durable objects pricing site:developers.cloudflare.com after:2025-06-01"

max_results: number of results (1-50, default 10). Asking for more does not cost more but uses more context.
include_content: include the full page text of every result. This is very large (often thousands of tokens per result) and rarely needed — leave it false and use web_fetch on one or two chosen URLs instead.

Results may come from a shared cache.
refresh: skip the cache and search again now; the new results also replace the cached copy for everyone. Billed at the full (uncached) rate, so only set it when the user needs the latest information or a cached result looks out of date.

Input parameters:

- `include_content` (boolean): Include full page text for every result. Very large; rarely needed. Default false.
- `max_results` (integer): Number of results to return, 1-50. Default 10.
- `query` (string, required): Search query, 1-128 characters. Supports site:, -site:, lang:, after:YYYY-MM-DD, before:YYYY-MM-DD.
- `refresh` (boolean): Skip the cache and search again now (full price); the fresh results replace the cached copy. Default false.

### `web_fetch` (~141 tokens)

Fetch web page

Fetch a web page and return its title and main content as Markdown.

Use it to read a specific page in full: a URL the user gave you, or a promising result from web_search whose snippet was not enough. Only http and https URLs are supported. Pages may be served from a shared cache; set refresh to read the live page (billed at the full rate) when the page changes often or the cached copy looks stale.

Input parameters:

- `refresh` (boolean): Skip the cache and fetch the live page (full price); the result replaces the cached copy. Default false.
- `url` (string, required): The http or https URL of the page to read.

## Common questions

### What is the Dipper MCP server?

Dipper is an MCP server listed in the public MCP registry as com.dipper-search/dipper. Web search and page fetch for AI agents. Results come from a shared cache; cached calls cost less. This page covers its hosted endpoint (https://dipper-search.com/mcp/free).

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

Dipper scores 70 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 Dipper MCP server expose?

Dipper exposes 2 tools: web_search, web_fetch. Their descriptions and schemas cost roughly 592 tokens of context every time the server is loaded.

### Does the Dipper MCP server require authentication?

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

### Is the Dipper MCP server still maintained?

Dipper 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.
