Description
Persistent reader mode for AI. Save web pages, organise into collections, distil to dense context, and serve it all through MCP.
Usage Guidance
This skill appears to do what it claims (an MCP-backed reader library), but exercise caution before enabling it. The runtime setup uses npx to download and execute 'sombra-mcp' from the npm registry — review the package's source, publisher, and npm page before running it. Prefer installing a vetted release or running the server in an isolated environment/container. Do not paste long-lived high-privilege secrets directly into configs where other processes/users can read them; create a limited-scope token for Sombra that can be revoked, and store it securely (or use an OS-level secret manager). If you can't verify the npm package or its authors, treat this as higher risk and avoid installation.
Capability Analysis
Type: OpenClaw Skill
Name: sombra-ai-reader-mode
Version: 1.0.1
The skill is a legitimate MCP (Model Context Protocol) server integration for Sombra (sombra.so), a persistent knowledge management service for AI agents. It provides tools for saving web pages as markdown, organizing them into collections, and distilling them for context. The setup utilizes 'npx' to execute the 'sombra-mcp' package, which is a standard deployment pattern for MCP servers. No evidence of malicious intent, prompt injection, or unauthorized data exfiltration was found; all behaviors are consistent with the stated purpose of providing a research library for the agent.
Capability Assessment
Purpose & Capability
Name and description (persistent reader mode served via MCP) line up with the instructions: the skill tells you to run an MCP server (sombra-mcp) via npx and to supply a Sombra PAT. Requiring 'npx' is coherent with the approach of launching an npm-hosted MCP server.
Instruction Scope
SKILL.md instructs you to add an MCP server command to openclaw.json that includes the token inline (npx -y sombra-mcp --token <PAT>). That means the agent/user will execute a remote package at runtime and place a secret into a config file. The instructions do not ask the agent to read unrelated files, but they do direct runtime execution of external code and persistent storage of credentials — both higher-scope actions than simple read/search functionality.
Install Mechanism
There is no static install spec, but the runtime invocation uses npx to fetch and run 'sombra-mcp' from the npm registry. npx dynamically downloads and executes code from a third-party registry (potentially arbitrary), which is higher risk than using a vetted packaged binary or a documented release URL. The SKILL.md also passes '-y' to make this non-interactive, increasing the chance code runs without manual review.
Credentials
The skill does not request unrelated environment variables or credentials in the registry metadata. It legitimately requires a Sombra personal access token for the service. Note: the instructions recommend embedding the token in openclaw.json as a command arg, which stores a secret in your local config — consider scope/minimum permissions and secure storage.
Persistence & Privilege
always is false and the skill is user-invocable; it does not request permanent/global presence. It does direct adding an MCP server entry into openclaw.json (a normal configuration change for MCP connectors). This is expected behaviour, not an elevated privilege by itself.
