Security scores are indicators to help you make informed decisions, not guarantees. Always review permissions before connecting any MCP server.
Remote servers are capped at 8.0 because source code is not available for review. The score reflects endpoint verification only.

10 calls per IP. No auth, no signup. All 7 endpoints included.
Service wallet: 8qXedRydihKEETqU64UXtG2sYZaUhwR4HBFz4Suu27CV
Step 1 — Send SOL:
solana transfer 8qXedRydihKEETqU64UXtG2sYZaUhwR4HBFz4Suu27CV 0.1 --allow-unfunded-recipient
# 0.1 SOL = 1,000 credits
Step 2 — Pass tx signature as Bearer token (first call):
TX_SIG="5abc...your-tx-signature"
curl -X POST https://api.agent-toolbox.ai/v1/validate/imports \
-H "Authorization: Bearer $TX_SIG" \
-H "Content-Type: application/json" \
-d '{"language":"python","code":"import numpy"}'
Credits are verified on-chain and added instantly. The tx signature becomes your API key for all subsequent calls.
Step 3 — All subsequent calls use the same key:
curl -X POST https://api.agent-toolbox.ai/v1/verify \
-H "Authorization: Bearer $TX_SIG" \
-H "Content-Type: application/json" \
-d '{"outputType":"natural_language","llmResponse":"..."}'
| HTTP | error | Meaning |

Run these checks in order before executing or deploying any AI-generated code:
const code = await llm.generate("Write a Python web scraper using requests and beautifulsoup4");
// 1. Count tokens before the next LLM call (optional, for cost awareness)
const { total, estimatedCostUsd } = await client.countTokens({ text: code, model: "gpt-4" });
// 2. Scan for hardcoded secrets first (fast, <10ms)
const { safe: noSecrets, findings } = await client.scanSecrets({ code });
if (!noSecrets) throw new Error(`Secrets found: ${findings.map(f => f.type).join(", ")}`);
// 3. Validate imports against live registries
const { hallucinated } = await client.validateImports({ language: "python", code });
if (hallucinated.length > 0) throw new Error(`Hallucinated packages: ${hallucinated.map(p => p.name).join(", ")}`);

const result = await client.verify({ outputType: "code", language: "python", llmResponse: code });
if (result.verdict === "BLOCK") throw new Error("Code blocked: " + result.claims[0]?.evidence);
Run before passing any user input to an LLM:
const userMessage = req.body.message;
// Detect prompt injection before passing to LLM
const { risk, patterns, advice } = await client.scanInjection({ input: userMessage });
if (risk === "injection") {
return res.status(400).json({ error: "Input rejected", reason: advice });
}
// Now safe to use with LLM
const response = await llm.chat([
{ role: "system", content: systemPrompt },
{ role: "user", content: userMessage },
]);
Compress context before it gets expensive:
const CONTEXT_LIMIT = 4000; // target tokens
// Count tokens before every LLM call
const { total, contextWindowRemaining } = await client.countTokens({
messages: conversationHistory,
model: "gpt-4",
});
// Distill if approaching limit
if (total > CONTEXT_LIMIT * 0.8) {
const { messages, compressionRatio } = await client.distill({
messages: conversationHistory,
targetTokens: CONTEXT_LIMIT,
});
conversationHistory = messages;
console.log(`Context compressed ${Math.round((1 - compressionRatio) * 100)}%`);
}
const response = await llm.chat(conversationHistory);
For natural language outputs with source documents:
const answer = await llm.generate("Summarize the key findings from this research paper.");
// Verify against the original source docs
const result = await client.verify({
outputType: "natural_language",
llmResponse: answer,
sourceTexts: [researchPaperText], // enables NLI grounding check
enforcementMode: "flag", // flag rather than block for NL content
});
if (result.verdict === "FLAG") {
// Regenerate or surface for human review
console.warn("Potential hallucination:", result.claims.map(c => c.evidence));
}
| Situation | Use |
|---|---|
| AI generated code with imports | validate/imports → scan/secrets → scan/vulnerabilities |
| User input going to LLM | scan/injection first |
| Any LLM output before use | verify (most comprehensive) |
| Context window growing | tokens/count to check, distill to compress |
| LLM output grounded in documents | verify with sourceTexts |
| Deploying AI-generated code to prod | Full pipeline: injection → secrets → imports → vulns → verify |
Add to your MCP config — your agent gets quality tools immediately:
Claude Desktop (~/Library/Application Support/Claude/claude_desktop_config.json)
Cursor (~/.cursor/mcp.json)
Warp: Settings → Agents → MCP servers → Add
Recommended (after the package is published to npm):
{
"mcpServers": {
"agent-toolbox": { "command": "npx", "args": ["-y", "agentoolbox-mcp"] }
}
}
From source (local dev / before publish):
{
"mcpServers": {
"agent-toolbox": {
"command": "node",
"args": ["/absolute/path/to/agentoolbox/packages/mcp/dist/index.js"]
}
}
}
Build first:
git clone https://github.com/solhammer/agentoolbox
cd agentoolbox && pnpm install && pnpm --filter agentoolbox-mcp build
No API key or env vars are required — the MCP server runs all 15 tools in-process (free public data sources only).
MCP tools available (all 15 endpoints):

validate_imports | Check every import in AI-generated code against live registries |
verify_output | Full hallucination firewall on any LLM response |
distill_context | Compress conversation history to a token budget (TF-IDF) |

count_tokens | Token count + cost estimate for text or messages |
scan_vulnerabilities | Check packages against the OSV/CVE database |
scan_pii | Detect & redact PII/PHI/PCI before egress |
finance_units | Validate raw vs UI token amount (decimal safety) |
finance_price | Cross-source price validation |
finance_symbol | Resolve ticker/token identity |
finance_token_risk | Rug-pull / mint & freeze authority scan |
finance_slippage | Pool depth / price-impact estimate |
finance_order_risk | Composite pre-trade gate |
finance_position_check | Deterministic position limits + kill-switch |
Warp (local agents): Settings → Agents → MCP servers → + Add, choose the CLI/stdio option, and paste the config above.
Oz cloud agents / CLI: this repo ships agent-toolbox.mcp.json — a ready MCP config object you can pass directly:
# from the committed config file
oz agent run --mcp ./agent-toolbox.mcp.json --prompt "scan this text for PII before I log it"
# or inline
oz agent run --mcp '{"agent-toolbox":{"command":"npx","args":["-y","agentoolbox-mcp"]}}' --prompt "..."
After adding it in Warp, reference it by UUID for reuse (oz mcp list or Settings → Agents → MCP servers), or declare it under mcp_servers in an agent config file passed with -f.

Seven additional endpoints that protect AI trading agents from the most common — and most costly — trading failures.
Research backing: Lobstar Wilde decimal error (Feb 2026): agent sent 52M tokens instead of 52k, ~$440k book value → ~$40k realized due to slippage. Claude Code GH#46828: unauthorized $1,446 wallet sweep from scope violation. USENIX 2025: 19.7% of AI-generated packages hallucinated. IBM 2026: 68% of multi-agent pipelines contain hallucinations.

All trading agent failures share the same root cause: the agent proposed a trade and executed it without validating. The correct architecture:
LLM proposes trade
↓
[ 1. checkDecimals — raw amount sanity < 10ms ]
[ 2. checkPrice — stale/hallucinated price ~300ms ] → run in parallel
[ 3. checkRug — rug pull / mint authority ~500ms ]
[ 4. checkLiquidity — pool depth / slippage ~200ms ]
↓ only if all PASS/FLAG
[ 5. checkPosition — portfolio limits < 1ms ] ← non-overridable gate
↓ only if PASS
