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. How we score → Why this is hard to score →
Supply Chain Security23
- No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.Unverified
- Known CVEs were checked across the 92 of 92 dependencies we could resolve, so this covers what we could see, not the whole tree.Partial
- No install/post-install scripts declared.Pass
- 31 of 92 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency45
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 0 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability68
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 529 tokens (~132/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage90
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 71% of tool parameters carry a description.Partial
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 2 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "chat" implies "send" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Unverified: 1 category
A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
chat Chat with a model via Zerouter ~215
Send a prompt or a message list to any Zerouter model (Claude, GPT, Gemini, Grok, Kimi, ...). The request is routed automatically: Claude/Kimi -> /v1/messages, GPT/Grok/Codex -> /v1/responses, Gemini and other models -> /v1/chat/completions. Requires ZEROUTER_API_KEY.
| Name | Type | Req | Description |
|---|---|---|---|
| endpoint | string | – | Override routing. Default auto. |
| max_tokens | integer | – | Max output tokens (default 1024 for Claude/Kimi) |
| messages | array | – | Conversation history as {role, content} items |
| model | string | yes | Model ID, e.g. claude-sonnet-5-5, gpt-6-sol, gemini-3.8-flash, grok-4.6, kimi-k3 |
| prompt | string | – | User prompt. Appended after `messages` if both are given. |
| system | string | – | Optional system prompt |
| temperature | number | – | – |
No output schema declared.
No examples provided.
compare_models Compare models side by side ~79
Send the same prompt to 2-4 Zerouter models in parallel and return each answer with token usage, latency and estimated cost. Requires ZEROUTER_API_KEY.
| Name | Type | Req | Description |
|---|---|---|---|
| max_tokens | integer | – | – |
| models | array | yes | 2 to 4 model IDs |
| prompt | string | yes | – |
| system | string | – | – |
No output schema declared.
No examples provided.
get_pricing Get Zerouter pricing ~104
Public per-model prices on Zerouter in USD per 1M tokens (input/output), next to the official list price. No API key needed. Data comes from https://www.zerouter.ai/pricing.
| Name | Type | Req | Description |
|---|---|---|---|
| model | string | – | Filter by model ID or name substring, e.g. 'claude' or 'gpt-6' |
| provider | string | – | Filter by provider: anthropic, openai, gemini, grok, kimi |
No output schema declared.
No examples provided.
list_models List Zerouter models ~69
List model IDs available on Zerouter and the endpoint each one uses. Uses GET /v1/models when ZEROUTER_API_KEY is set, otherwise the public catalog at https://www.zerouter.ai/models.
| Name | Type | Req | Description |

How do I install the Zerouter MCP server?
Zerouter ships as an MCPB bundle, a single file you download and open in an MCP host that supports MCPB bundles, such as Claude Desktop. The host reads the launch command from the bundle's own manifest, so there is no command to copy. Before opening it, check the file's SHA-256 matches the one the MCP registry declares for it, 32aefe7c4f0952dec80c31154dfde93231a5cff38114a6a2aa55699012d475ab; the commands to do that are on this page. If it does not match, do not open it.
