Overview

AI-generated overview

Cortex is a local-first persistent knowledge system with OWL-RL reasoning, exposing 22 MCP tools to an assistant.

What you can do
  • Store and keep persistent knowledge across sessions in a local knowledge system
  • Query and reason over stored knowledge using OWL-RL inference
  • Work with the server's 22 MCP tools, whose individual names and parameters are not listed in the available material
When to use it
Worth considering when you want an assistant to retain structured knowledge between sessions and apply ontology-based reasoning to it, and you are comfortable running a local Python package on a desktop machine.
Requirements
Runs as a local stdio process installed from the PyPI package abbacus-cortex; desktop only, not available as a web executable. No authentication, environment variables or headers are declared.
Before you install
The tool list is not published, so what each of the 22 tools can read or change is unknown before installing; review the tools after connecting. Knowledge is described as local-first, but confirm where data is stored.

Installation

In SourceWeft

  1. Open Cortex in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

Score

25% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.

  • Tools listed15 pts

    Answer tools/list without a credential, or ship a package that starts in a sandbox without one.
