## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, 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.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - No install/post-install scripts declared.
  - No production dependencies, so there is no dependency health to assess.
- **Provenance & Transparency**: 97/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to pipeworx-io/mcp-openrouter).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 1 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 70/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 482 tokens (~160/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 23/100
  - Stability observed for 7 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 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 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.

### 2026-10-29 (score 80)

First indexed and scored.

## MCP tools (3)

### `list_models` (~215 tokens)

List LLMs from the OpenRouter catalog (~340 models across all major providers) with normalized $/1M-token pricing, context windows, and modality. Filter by search, free-only, minimum context, or modality (e.g. "image" for vision models). Sorted cheapest-first by completion price. Keyless.

Input parameters:

- `free_only` (boolean): If true, only return models whose prompt price is $0 (free tier).
- `limit` (number): Max models to return (default 25, max 60).
- `min_context` (number): Minimum context_length in tokens, e.g. 100000 or 200000.
- `modality` (string): Substring match on architecture.modality, e.g. "image" to find vision/multimodal models, "text->text" for text-only.
- `search` (string): Case-insensitive substring match against model id, name, and description. e.g. "claude", "gpt-4o", "deepseek".

### `get_model` (~117 tokens)

Get full details for one OpenRouter model by id — normalized $/1M pricing (prompt, completion, plus per-request/image/web-search costs), context window, modality, supported parameters, tokenizer, knowledge cutoff. e.g. id "anthropic/claude-sonnet-4.5". Keyless.

Input parameters:

- `id` (string, required): Exact model id, e.g. "anthropic/claude-sonnet-4.5", "openai/gpt-4o", "google/gemini-2.5-pro".

### `compare_models` (~98 tokens)

Side-by-side comparison of pricing ($/1M tokens), context window, and modality for 2-5 OpenRouter models. Answers "is claude-sonnet-4.5 cheaper than gpt-4o". Keyless.

Input parameters:

- `ids` (array, required): Array of 2-5 exact model ids, e.g. ["anthropic/claude-sonnet-4.5", "openai/gpt-4o"].

## Common questions

### What is the Openrouter MCP server?

Openrouter is an MCP server listed in the public MCP registry as io.github.pipeworx-io/openrouter. OpenRouter Models MCP. This page covers its npm package (@pipeworx/mcp-openrouter).

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

Openrouter scores 83 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. 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 Openrouter MCP server expose?

Openrouter exposes 3 tools: list_models, get_model, compare_models. Their descriptions and schemas cost roughly 430 tokens of context every time the server is loaded.

### Is the Openrouter MCP server still maintained?

Openrouter 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.

### What licence is the Openrouter MCP server under?

Openrouter declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the Openrouter MCP server?

VerifyMCP ran 16 checks on Openrouter, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
