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":"..."}'
Error responses
| HTTP | error | Meaning |
|---|
402 | free_tier_exhausted | 10 free calls used — send SOL to continue |
402 | insufficient_credits | Balance empty — send more SOL |
401 | invalid_token | Empty or malformed Bearer token |

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
| 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 |
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):
| Tool | Description |
|---|
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) |

rx_check | Medication unit / overdose / interaction gate |
check_tool_args | Validate tool-call args against schema + policy |
check_infra_plan | Static IaC blast-radius gate (Terraform / IAM / K8s) |
check_citation | Validate US case citations + quote fidelity |
compute_deadline | Court / calendar deadline math |
validate_identifier | Checksum-validate IBAN / card / VIN / NPI / … |

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.

Roadmap
Agentoolbox ships in waves — 26 tools across 6 suites today (through Wave 4), with regulated-vertical and platform-moat tools planned next. The full plan, design contract, and near-term supply-chain hardening track live in docs/ROADMAP.md.
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
| Endpoint | What it prevents | Credits |
|---|
POST /v1/finance/units | Decimal/units errors (Lobstar-class $440k mistake) | 1 |
POST /v1/finance/price | Stale and hallucinated prices | 2 |
POST /v1/finance/symbol | Wrong ticker / token identity confusion | 1 |
POST /v1/finance/token/risk | Rug pulls, mint authority, frozen tokens | 3 |
POST /v1/finance/slippage | Thin pool slippage disaster | 2 |
POST /v1/finance/order/risk | Full pre-trade gate (runs all checks) | 5 |
POST /v1/finance/position/check | Position limits + kill-switch (no API calls) | 1 |
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
