## 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 2026-09-24.

- **Endpoint Security**: 80/100
  - 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 is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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**: 68/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 322 tokens (~322/item across 1 items; 1 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 3/100
  - Stability observed for 1 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.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 75/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "remove_duplicates" implies "remove" and declares readOnlyHint instead, contradicting what its own name says it does.
  - An AI judge read all 2 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.

## Install

### How do I install the RemoveDuplicates.org MCP server?

RemoveDuplicates.org is a hosted endpoint at https://removeduplicates.org/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

```bash
claude mcp add --transport http org-removeduplicates-remove-duplicates 'https://removeduplicates.org/mcp'
```

### Cursor

```json
{
  "mcpServers": {
    "org-removeduplicates-remove-duplicates": {
      "url": "https://removeduplicates.org/mcp"
    }
  }
}
```

### VS Code

```json
{
  "servers": {
    "org-removeduplicates-remove-duplicates": {
      "type": "http",
      "url": "https://removeduplicates.org/mcp"
    }
  }
}
```

### Codex

```toml
[mcp_servers.org-removeduplicates-remove-duplicates]
url = "https://removeduplicates.org/mcp"
```

### opencode

```json
{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "org-removeduplicates-remove-duplicates": {

      "enabled": true
    }
  }
}
```

### OpenClaw

```bash
openclaw mcp add org-removeduplicates-remove-duplicates --url 'https://removeduplicates.org/mcp' --transport streamable-http
```

### Hermes

```yaml
mcp_servers:
  org-removeduplicates-remove-duplicates:
    url: "https://removeduplicates.org/mcp"
```

### Netclaw

```json

  "McpServers": {
    "org-removeduplicates-remove-duplicates": {
      "Transport": "http",
      "Url": "https://removeduplicates.org/mcp"
    }
  }
}
```

### Vellum

```bash
assistant mcp add org-removeduplicates-remove-duplicates -t streamable-http -u 'https://removeduplicates.org/mcp'
```

### Other

```json
{
  "mcpServers": {
    "org-removeduplicates-remove-duplicates": {
      "type": "http",
      "url": "https://removeduplicates.org/mcp"
    }
  }
}

Remove duplicates

Remove duplicate lines from a text list, or duplicate rows from CSV/TSV text such as rows copied from Excel or Google Sheets. Uses the same engine as removeduplicates.org and returns the cleaned text with counts. Stateless: the text is processed in memory for this call only and is never stored.

Input parameters:

- `compare`: Tables only: "row" compares entire rows; a zero-based column index or an array of indices compares only those columns.
- `format` (string): auto detects CSV/TSV tables; lines compares whole lines; table forces CSV/TSV parsing.
- `header` (boolean): Tables only: keep the first row as a header outside duplicate checks and counts.
- `ignoreCase` (boolean): Treat values such as Apple and apple as duplicates.
- `keep` (string): Which occurrence of a duplicate survives.
- `order` (string): preserve keeps the original order; sort returns a natural (numeric-aware) sort.
- `removeEmpty` (boolean): Drop blank lines or all-blank rows.
- `text` (string, required): The list or table text: one item per line, or CSV/tab-separated rows. Up to 131072 UTF-8 bytes.
- `trim` (boolean): Ignore surrounding spaces when comparing and return trimmed values.

Output parameters:

- `format` (object)
- `stats` (object)
- `text` (string): The cleaned text, rows joined with \n.
