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 Security25
- 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 3 of 3 dependencies we could resolve, so this covers what we could see, not the whole tree.Partial
- No install/post-install scripts declared.Pass
- 0 of 3 dependencies flagged as unhealthy. View diagnostics → Pass
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 5 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability76
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 237 tokens (~79/item across 3 items; 3 tools + 0 resources), lean.Pass
- 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 Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "compare_models" implies "send" and declares readOnlyHint instead, contradicting what its own name says it does. See how to fix → Fail
- An AI judge read all 3 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 →
ask_model ~106
Ask another LLM through onomeo and return its answer. Use it for a second opinion, a review from a different model, or to hand off a side question. "auto" picks a healthy free model.
| Name | Type | Req | Description |
|---|---|---|---|
| model | string | – | Model id from list_models. Defaults to "auto". |
| prompt | string | yes | The full question. The other model sees only this text, so include the code or context it needs. |
| system | string | – | Optional system prompt. |
No output schema declared.
No examples provided.
compare_models ~87
Send the same question to 2-4 models at once and return the answers side by side. Each model counts as one call against the limit.
| Name | Type | Req | Description |
|---|---|---|---|
| models | array | yes | Model ids from list_models. |
| prompt | string | yes | The full question. The other model sees only this text, so include the code or context it needs. |
| system | string | – | Optional system prompt. |
No output schema declared.
No examples provided.
list_models ~44
List the models onomeo serves right now: which are free to call, which are pay-as-you-go, and the current free call limit. Works without an API key.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
How do I install the onomeo MCP server?
onomeo 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, 3810f6fdb2b50b344c80c8f86b96d561fbd4c850c6834f471d338687f326484b; the commands to do that are on this page. If it does not match, do not open it.

What is the onomeo MCP server?
onomeo is an MCP server listed in the public MCP registry as io.github.Owaid0723666/onomeo-mcp. Ask free LLMs (DeepSeek, GLM, Gemini, Mistral) for a second opinion from any MCP client. This page covers its MCPB bundle (https://github.com/Owaid0723666/onomeo-mcp/releases/download/v0.1.0/onomeo-mcp.mcpb).
Is the onomeo MCP server safe to use?
onomeo scores 47 out of 100 on VerifyMCP. It declares no install or post-install scripts. 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 onomeo MCP server expose?
onomeo exposes 3 tools: list_models, ask_model, compare_models. Their descriptions and schemas cost roughly 237 tokens of context every time the server is loaded.
What licence is the onomeo MCP server under?
onomeo declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
