You need dedicated capabilities in the Security domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: API Key required (Freemium).
You have access to required keys: MCPSKILLS_API_KEY.
Pre-install trust layer for MCP servers, AI skills, and npm packages. Scores any repo or package across 15 signals (incl. OSV/KEV/EPSS vulnerability intelligence) with safety scanning for prompt injection, credential theft, and supply-chain risk; the autogate tool returns a go/no-go install decision. Listed in the official MCP Registry as io.mcpskills/server. npm: @mcpskillsio/server. https://mcpskills.io
Pre-action risk gate for AI agents. One forecast tool the agent calls before any irreversible action (send money, run SQL, delete data); returns a risk score (0–100), reversibility class, named red flags from 28 failure modes, and a gate: proceed / confirm / human-required.
Tools & Capabilities Breakdown
Mcpskills Server Tools (9)
check_trust_score
Score any AI skill, MCP server, or GitHub repo for trustworthiness. Returns a trust score (0-10) across 4 dimensions: Alive, Legit, Solid, Usable. Accepts: owner/repo, GitHub URL, npm package (npm:@scope/name or @scope/name), Smithery URL, or OpenClaw URL. AI skills get enhanced safety scanning. Set MCPSKILLS_API_KEY for full reports.
scan_safety
Run a focused safety scan on an AI skill or MCP server. Checks for prompt injection, shell execution, network exfiltration, credential theft, obfuscated payloads, public network binding (0.0.0.0), and risky npm lifecycle scripts (preinstall/install/postinstall). Accepts any input format (owner/repo, npm package, Smithery URL, etc.).
list_packages
Browse curated, pre-scored AI skill packages organized by use case. Each package contains vetted skills with trust scores. Available packages: Claude Power User, Full-Stack Vibe Coder, Data & Research, DevOps & Infrastructure, Content & Marketing.
get_badge
Get a trust badge URL for any repo or package. Returns a shields.io-style SVG badge showing the trust score and tier. Embed in READMEs. Badge auto-updates hourly.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Mcpskills Server is categorized under Security and uses a local stdio subprocess. In contrast, Blackwall Mcp belongs to Security using local stdio subprocess. Select Mcpskills Server when you need capabilities focused on security and Blackwall Mcp when you require tools for security.
Start monitoring a repo or package for trust score changes. Alerts when score changes significantly (±0.3 points or tier change). Requires a paid API key.
check_watched
Re-scan all watched repos and check for score changes. Returns any repos whose trust score changed significantly since last check.
batch_check
Check up to 5 repos or packages in one call. Returns a trust assessment for each. Requires a Developer Pro or Team API key. Accepts any mix of formats (owner/repo, npm packages, registry URLs).
auto_gate
Should I install this? Returns a simple go/no-go decision with reasoning. Accepts any format: owner/repo, npm package, Smithery URL, etc. Returns { proceed: true/false, reason: "..." }.
build_stack
Recommend a vetted stack of trusted tools for a described task. Describe what you're building (e.g., "Next.js app with auth, payments, and AI chat") and get back a curated list of the highest-scoring repos in each relevant category, pre-scored and ready to install. Returns tool names, trust scores, tiers, and install hints. Use this instead of guessing which tools to recommend — every suggestion is backed by live trust data.
Blackwall Mcp Tools (2)
forecast
Call this BEFORE taking ANY irreversible or high-stakes action — sending an email, making a payment, running SQL, deleting files or data, posting public content, calling an external API that changes state. It returns a risk score (0–100), a recommendation (GO / CAUTION / STOP), and named red flags. If the recommendation is STOP, do not take the action — surface the flags to the user instead. If CAUTION, confirm with the user first.
observe
Call this AFTER an action runs (or after deciding NOT to run it because BLACK_WALL returned STOP/HUMAN_REQUIRED) to report what actually happened. Closes the loop with the earlier forecast — BLACK_WALL compares your observation to the prediction to track accuracy and improve future forecasts. FREE — no tokens charged. Always call this if you have a forecast_id from a recent `forecast` call.
