Dead
Every channel of this server has been unreachable for long enough to be marked dead. Its trust score is pinned to 0 and does not recover automatically: even once the server responds again it stays dead until it is manually reinstated.
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 Security50
- No malware found by supply-chain analysis.Pass
- Known CVEs could not be checked: we could not find this package in its registry.Unverified
- Install-script risk not yet assessed.Unverified
- Dependency health could not be checked: we could not find this package in its registry.Unverified
Provenance & Transparency0
- Repository check failed: the declared repository URL returned HTTP 404. See how to fix → View diagnostics → Fail
- Provenance check failed: the registry has no such package, so there's no artefact to verify. See how to fix → View diagnostics → Fail
- License check failed: the registry has no such package, so no license can be read. See how to fix → Fail
- Maintenance check failed: the registry has no such package, so there's no release history to read. See how to fix → Fail
- Security-disclosure policy not yet verified: we couldn't inspect the source repository.Unverified
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: 5 categories
Categories scored 0 because our sandbox could not run this package, so we have no schema for these checks to read. That is a gap on our side rather than a finding about the package, and we only credit what we can confirm, so the score stands at 0 until we can run it. How we score packages →

No change was recorded against any check on this day. Stability & Change Management went from 80 to 83. That category is still filling its 30-day observation window: 24 days of observed history at the previous scan, 25 at this one. The score rises as the window fills, whether or not the server changes.

No change was recorded against any check on this day. Stability & Change Management went from 73 to 77. That category is still filling its 30-day observation window: 22 days of observed history at the previous scan, 23 at this one. The score rises as the window fills, whether or not the server changes.
Diagnostic detail from the automated scan of this channel: what the scanner observed at each step, so you can see exactly where a check passed or failed. It is informational only and never changes the trust score.

Provenance Package not found
The registry answered that no such package exists, so no provenance could be looked up.

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.
How do I install the SignalBrain MCP server?
SignalBrain runs locally as a PyPI package, launched with uvx signalbrain. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

What is the SignalBrain MCP server?
SignalBrain is an MCP server listed in the public MCP registry as io.github.whitestone1121-web/signalbrain. Verifiable receipts for governed process changes; emit, validate, and gate trust. This page covers its PyPI package (signalbrain).
Is the SignalBrain MCP server safe to use?
SignalBrain scores 0 out of 100 on VerifyMCP. 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.
Is the SignalBrain MCP server still maintained?
SignalBrain has been unreachable for long enough that we treat it as dead, and its score is pinned to zero. We last reached this channel on 22 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
