Description
Access Jewish texts, commentaries, and daily study materials from Torah, Talmud, and more via the Sefaria MCP server.
Usage Guidance
This skill appears to be a legitimate Sefaria MCP adapter, but it depends on downloading and running code from npm at runtime while the manifest fails to declare npm/npx as required. Before installing or allowing the agent to run it:
- Inspect the npm package and GitHub repository (abeperl/sefaria-mcp-server). Verify the source, recent activity, maintainer identity, and issues/PRs.
- Prefer a pinned package version rather than unpinned 'npx sefaria-mcp-server' to avoid surprise updates.
- Review package.json and any install/postinstall scripts; run 'npm pack' and inspect the tarball before executing.
- Avoid global installs; run in an isolated environment or container if possible.
- If you cannot review the package, treat npx usage as running arbitrary code and exercise caution (do not run with elevated privileges or on sensitive hosts).
If you want this skill but are uncomfortable running unpinned npm packages, ask the publisher for a signed release, a pinned version, or instructions for a self-hosted adapter built from the published GitHub source. If you need more certainty, provide the package's npm page or repository contents and I can help inspect them.
Capability Analysis
Type: OpenClaw Skill
Name: sefaria-mcp
Version: 1.0.0
The skill bundle contains documentation for the Sefaria MCP server, which provides access to Jewish religious texts. The instructions in SKILL.md and metadata in _meta.json are consistent with the stated purpose and do not contain any malicious commands, prompt injections, or suspicious behaviors. The installation steps using 'npx sefaria-mcp-server' are standard for Node-based MCP tools.
Capability Assessment
Purpose & Capability
Name, description, and listed tools align with a Sefaria MCP server adapter; asking the agent to run the sefaria-mcp-server package is coherent with the stated purpose. However, the skill metadata did not declare required binaries (npm/npx), which is an omission and reduces transparency.
Instruction Scope
SKILL.md instructs running 'npm install -g' or 'npx sefaria-mcp-server' and adding an MCP config that runs npx. Those instructions will download and execute third-party code at runtime — the instructions do not provide any safety guidance (no pinned version, no verification, no instructions to inspect code) and the manifest gives no indication that the agent will invoke package managers.
Install Mechanism
There is no install spec in the manifest, but runtime instructions rely on npm/npx to fetch a package from the public npm registry. Installing/executing an npm package (via npx or global install) is a moderate-to-high risk action because packages can contain install or postinstall scripts and arbitrary code; mitigating details (source verification, pinned versions) are absent though a GitHub repo and npm link are provided.
Credentials
The skill does not request environment variables, credentials, or config paths beyond instructing to modify the MCP config (which is appropriate). There are no unexplained secrets or unrelated credential requests.
Persistence & Privilege
always is false and model invocation is allowed (platform default). The skill asks to add an MCP server entry to the agent's MCP config — this is expected behavior for an adapter and does not appear to modify unrelated skills or system-wide settings.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install sefaria-mcp - After installation, invoke the skill by name or use
/sefaria-mcp - Provide required inputs per the skill's parameter spec and get structured output
