Authentication & SOL payments

Free tier

10 calls per IP. No auth, no signup. All 26 tools included.

Paid tier — autonomous SOL micropayments

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":"..."}'

    })
  );
  return sendAndConfirmTransaction(connection, tx, [keypair]);

Integration patterns

Pattern 1: Code generation pipeline

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(", ")}`);

// 4. Check packages for known vulnerabilities
const { safe: noVulns, findings: vulns } = await client.scanVulnerabilities({
  packages: [...valid.map(p => p.name)],
  language: "python",
});
if (!noVulns) console.warn("Vulnerable packages:", vulns);

// 5. Full hallucination firewall (most comprehensive, use for final gate)
const result = await client.verify({ outputType: "code", language: "python", llmResponse: code });
if (result.verdict === "BLOCK") throw new Error("Code blocked: " + result.claims[0]?.evidence);

Pattern 2: User input sanitization

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 },
]);

Pattern 3: Long-running agent context management

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);

Pattern 4: Factual content verification

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));
}

Pattern 5: Agent decision guide — which tool to use when

MCP integration

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 26 tools in-process (free public data sources only).

MCP tools available (all 26 tools):

Use it in Warp & Oz cloud agents

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.

TypeScript SDK

npm install @agentoolbox/sdk

import { AgentoolboxClient } from "@agentoolbox/sdk";

const client = new AgentoolboxClient({
  baseUrl: "https://api.agent-toolbox.ai",
  apiKey: process.env.AGENTOOLBOX_API_KEY, // Solana tx signature — omit for free tier
});

// A representative slice of the 26 tools — full surface in openapi.json
await client.validateImports({ language: "python", code });
await client.verify({ outputType: "code", language: "python", llmResponse: code });
await client.scanPii({ text: outboundMessage });
await client.scanCommand({ command: "rm -rf /tmp/cache" });
await client.scanUrl({ url: "https://example.com/webhook" });
await client.screenSanctions({ name: counterpartyName });
await client.checkToolArgs({ args, schema });
await client.validateIdentifier({ value: "DE89370400440532013000", type: "iban" });
await client.scanSql({ sql: "DELETE FROM users WHERE id = 42" });

Finance Protection Toolkit

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.

Service overview

POST /v1/finance/units

Prevents the most catastrophic class of error: sending 52,439,283 tokens when you meant 52,439 because the agent confused raw on-chain amounts with UI amounts.

Finance Toolkit — Developer Integration Guide

The pattern: propose → validate → execute

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
Execute transaction

Install

npm install agent-toolbox-sdk     # REST client for all 26 endpoints
npm install @agentoolbox/finance  # TypeScript library (direct, no API calls for checkPosition)

Minimal Solana trading guard

import { checkDecimals, checkRug, checkLiquidity, checkPosition } from "@agentoolbox/finance";

async function guard(tokenMint: string, rawAmount: string, uiAmount: number, tradeUsd: number) {
  const [decimals, rug, liquidity] = await Promise.all([
    checkDecimals({ tokenAddress: tokenMint, rawAmount, uiAmount, chain: "solana" }),
    checkRug({ address: tokenMint, chain: "solana" }),
    checkLiquidity({ tokenAddress: tokenMint, tradeUsd, chain: "solana" }),
  ]);

  for (const check of [decimals, rug, liquidity]) {
    if (check.verdict === "BLOCK") throw new Error("Trade blocked: " + check.risks[0]?.detail);
  }

  const position = checkPosition(
    { symbol: tokenMint, side: "buy", tradeUsd, assetType: "crypto" },
    { totalValueUsd: 50000, cashUsd: 20000 }
  );
  if (position.verdict === "BLOCK") throw new Error("Position limit: " + position.violations[0]);
}
