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 Security0
- 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 could not be checked: we found no dependency list to check in this bundle: either it runs a compiled binary, whose bundled manifests we do not read, or none of the package.json, requirements.txt, pyproject.toml or uv.lock files it ships for its runtime declares a dependency we can read (a requirements.txt that only points at a setup.py project, a local path, or a nested requirements file we cannot follow counts as none).Unverified
- Install-script risk not yet assessed.Unverified
- Dependency health could not be checked: we found no dependency list to check in this bundle: either it runs a compiled binary, whose bundled manifests we do not read, or none of the package.json, requirements.txt, pyproject.toml or uv.lock files it ships for its runtime declares a dependency we can read (a requirements.txt that only points at a setup.py project, a local path, or a nested requirements file we cannot follow counts as none).Unverified
Provenance & Transparency84
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to keyline-dev/keyline). View diagnostics → Pass
- License check failed: the license (PolyForm-Shield-1.0.0) isn't a recognized OSI-approved license. See how to fix → Fail
- Actively maintained (last published 1 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability0
- Schema quality not yet verified: our sandbox could not run this package, so we have no schema to assess.Unverified
Stability & Change Management0
- Stability not yet verified: our sandbox could not run this package, so we have no schema to compare.Unverified
Tool Coverage0
- Tool coverage not yet verified: our sandbox could not run this package, so we have no tool definitions to assess.Unverified
Tool Safety0
- Tool safety not yet verified: our sandbox could not run this package, so we have no tool text to scan.Unverified
Capabilities0
- Protocol version not yet verified: our sandbox could not run this package, so we never saw its MCP handshake.Unverified
Unverified: 6 categories
Categories scored 0 because we could not verify them: 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.
How do I install the keyline MCP server?
keyline 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, 5af4beab3830c6bb140db695e2e2632f8b1ba9743f831ee3d7fea975d1dccc79; the commands to do that are on this page. If it does not match, do not open it.

Run it in the folder you saved the bundle to, then open the file with an MCPB-capable host such as Claude Desktop.

Background: How many MCP packages publish verified provenance →
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 →
Tools for package channels are captured by running the package in an isolated sandbox. Our sandbox could not run this package, so no tool list has been captured. That is a gap on our side, not a finding about the package.
What is the keyline MCP server?
keyline is an MCP server listed in the public MCP registry as io.github.keyline-dev/keyline. Design engine for AI agents: images and video at every size, no Chrome needed. This page covers its MCPB bundle (https://github.com/keyline-dev/keyline/releases/download/v0.7.0/keyline-mcp-0.7.0.mcpb).
Is the keyline MCP server safe to use?
keyline scores 17 out of 100 on VerifyMCP. 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 licence is the keyline MCP server under?
keyline declares the PolyForm-Shield-1.0.0 licence, which is not on the OSI-approved list. Read the terms before using it at work, and note this covers the source only, not the cost of any service it calls.
