This repo hosts tooltrust.dev — the website and pre-scanned report data. If you want to scan your own MCP servers, go to tooltrust-scanner.
A public registry of AI agent tools, continuously scanned for prompt injection, data exfiltration, and privilege escalation by ToolTrust Scanner.
🚨 Supply-Chain Incident Coverage (March 2026) ToolTrust now detects and blocks confirmed supply-chain incidents including the LiteLLM / TeamPCP compromise and the malicious axios npm publish (
axios@1.14.1,axios@0.30.4). For npm-backed MCP servers, ToolTrust also scores dependency visibility, transitive lockfile evidence, lifecycle scripts, and IOC indicators such asplain-crypto-js.

ToolTrust Scanner check IDs referenced in all reports:
| ID | Severity | Detects |
|---|---|---|
| 🛡️ AS‑001 | Critical |
Tool Poisoning — Adversarial prompts hidden in tool descriptions (ignore previous instructions, <INST>) |
| 🔑 AS‑002 | High/Low |
Permission Surface — exec, network, db, fs beyond stated purpose; over-broad input schema |
| 📐 AS‑003 | High |
Scope Mismatch — Tool name contradicts its permissions (e.g. read_config with exec) |
| 📦 AS‑004 | High/Critical |
Supply Chain CVEs — Known CVEs in bundled dependencies via OSV |
| 🔓 AS‑005 | High |
Privilege Escalation — admin/:write OAuth scopes; sudo/impersonate in descriptions |
| ⚡ AS‑006 | Critical |
Arbitrary Code Execution — evaluate_script, _evaluate suffix, execute javascript, page.evaluate() patterns |
| ℹ️ AS‑007 | Info |
Insufficient Tool Data — Tool lacks a valid description or schema |
| 🚨 AS‑008 | Critical |
Known Compromised Package — Offline embedded blacklist of confirmed supply-chain attacks (LiteLLM 1.82.7/1.82.8, Trivy v0.69.4-v0.69.6, Langflow <1.9.0, Axios 1.14.1/0.30.4). Zero-latency, no network required. |
| 🔤 AS‑009 | Medium |
Typosquatting — Tool name within edit-distance 2 of a well-known MCP tool, suggesting impersonation |
| 🗝️ AS‑010 | Medium |
Secret Handling — Input params accepting API keys/passwords; credentials logged insecurely |
| ⚡ AS‑011 | Low |
DoS Resilience — No rate-limit, timeout, or retry config on network/exec tools |
| 🔄 AS‑012 | High |
Rug-Pull — Tool set changed between scans of the same version without a version bump (directory pipeline only) |
| ℹ️ AS‑014 | Info |
Dependency Inventory Unavailable — MCP server exposed neither metadata.dependencies nor a repo_url, so supply-chain coverage is limited and must be treated as incomplete |
Medium/High |
Suspicious NPM Lifecycle Script — npm dependency publishes preinstall / postinstall / similar install-time scripts; severity rises for remote-fetch or inline-execution patterns |
|
| 🚨 AS‑016 | Critical |
Suspicious NPM IOC Dependency — published npm metadata or install-time scripts reference a known malicious IOC package, domain, URL, or reviewed script pattern such as plain-crypto-js, even if the top-level package name is new |
Medium |
Suspicious Data Exfiltration Description — tool description explicitly suggests sending user data, content, or conversation history to external / remote endpoints, without classifying it as prompt injection | |
| ℹ️ AS‑018 | Info |
Embedded MCP Server Detected — source-level MCP SDK usage was found, but tools could not be enumerated from a manifest or live handshake, so manual review is still required |
| 👥 AS‑013 | High/Medium |
Tool Shadowing — Duplicate or near-duplicate tool name hijacks calls intended for a trusted tool |
Full details → docs/methodology.md
Let your AI agent scan its own tools. Add ToolTrust as an MCP server in your .mcp.json or claude_desktop_config.json:
{
"mcpServers": {
"tooltrust": {
"command": "npx",
"args": ["-y", "tooltrust-mcp"]
}
}
}This gives your agent five security tools:
| Tool | Description |
|---|---|
tooltrust_scan_config |
Scan all MCP servers in your .mcp.json or ~/.claude.json in parallel |
tooltrust_scan_server |
Launch and scan a specific MCP server |
tooltrust_scanner_scan |
Scan a JSON blob of tool definitions |
tooltrust_lookup |
Look up a server's trust grade from this directory |
tooltrust_list_rules |
List all security rules with IDs and descriptions |
Claude Code users: ask your agent to run tooltrust_scan_config to audit every MCP server in your project in one shot.
Request a scan — open an issue with the tool's public URL and version.
Dispute a finding — open an issue referencing the finding ID (e.g. AS-002).
Integrate ToolTrust Scanner — see docs/dev.md for the data pipeline and schema spec.
If your MCP server was audited and earned a grade, add our badge to your repo:
Grade A (recommended) — copy this into your README:
[](https://github.com/AgentSafe-AI/tooltrust-directory)Other grades — replace grade-a with grade-s, grade-b, grade-c, grade-d, or grade-f:
| Grade | Badge |
|---|---|
| S |  |
| A |  |
| B |  |
| C |  |
| D |  |
| F |  |

The registry table above is kept up to date by a daily GitHub Actions workflow:
.github/workflows/daily-audit.yml ← cron 00:00 UTC + manual dispatch
Each run:
- Discovers popular MCP servers via GitHub Search (50+ stars) plus Smithery-native servers (10+ uses)
- Scans new/updated tools with ToolTrust Scanner + OSV supply-chain analysis
- Publishes updated reports to
data/reports/and regenerates this README
