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 Security91
- No malware found by supply-chain analysis.Pass
- CVE check failed: a known high-severity CVE affects filelock 3.32.7, reached via litellm > filelock. A fixed version is available. View diagnostics → Fail
- Runs uv_build at install time, a recognised build step with no custom scripting around it. View diagnostics → Pass
- 5 of 84 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency6
- Repository check failed: the declared repository URL returned HTTP 404. See how to fix → View diagnostics → Fail
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- License check failed: the license (BUSL-1.1) isn't a recognized OSI-approved license. See how to fix → Fail
- Actively maintained (last published 114 days ago).Pass
- Security-disclosure policy not yet verified: we couldn't inspect the source repository.Unverified
Schema Quality & AI Usability0
- Schema quality not yet verified: this package could not be installed in a clean environment, so we have no schema to assess.Unverified
Stability & Change Management0
- Stability not yet verified: this package could not be installed in a clean environment, so we have no schema to compare.Unverified
Tool Coverage0
- Tool coverage not yet verified: this package could not be installed in a clean environment, so we have no tool definitions to assess.Unverified
Tool Safety0
- Tool safety not yet verified: this package could not be installed in a clean environment, so we have no tool text to scan.Unverified
Capabilities0
- Protocol version not yet verified: this package could not be installed in a clean environment, so we never saw its MCP handshake.Unverified
Unverified: 5 categories
Categories scored 0 because our sandbox has not given us the schema these checks need 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 the capture succeeds. We are working through the fleet, so this normally clears without any action from you. How we score packages →

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. The most recent sandbox run could not capture a tool list from this package.
How do I install the Cortex MCP server?
Cortex runs locally as a PyPI package, launched with uvx abbacus-cortex. 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 Cortex MCP server?
Cortex is an MCP server listed in the public MCP registry as io.github.abbacusgroup/cortex. Persistent knowledge system with OWL-RL reasoning and 22 MCP tools. Local-first. This page covers its PyPI package (abbacus-cortex).
Is the Cortex MCP server safe to use?
Cortex scores 29 out of 100 on VerifyMCP. We recorded 13 known advisories against it as of 5 November 2026. 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 Cortex MCP server still maintained?
Cortex 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 Cortex MCP server under?
Cortex declares the BUSL-1.1 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.
