ToolBooth
Description
Toolbooth eliminates API key friction for AI agents. Instead of managing dozens of API keys, signups, and billing accounts, your agent connects to one MCP endpoint and pays USDC micropayments per tool call via the x402 protocol on Solana mainnet. 22 tools across two categories: Solana Intelligence — on-chain data powered by Helius: • token_price ($0.0005) — real-time USD price for any SPL token • wallet_profile ($0.005) — full wallet breakdown with USD values • token_risk_score ($0.005) — 0-100 risk score from holder analysis • transaction_parse ($0.002) — human-readable transaction parsing • whale_alert ($0.01) — detect large wallet movements • dex_liquidity ($0.002) — pool depth and TVL ratings • token_holders ($0.005) — holder distribution and concentration • wallet_pnl ($0.05) — realized/unrealized PnL from swap history • copy_trade_signals ($0.01) — active positions and trading patterns Agent Concierge — we hold the API keys: • web_search ($0.01)
What our measurements say
ToolBooth is a remote MCP server published at toolbooth.io. It has been probed 5 times since 9/10/2026. It answered in 5 of them (100.0%), a near-uninterrupted record. Median response time is 985 ms, a delay an agent will notice. It exposes a broad tool surface of 58 tools. On the protocol side it still runs 2025-11-25 and has not moved to the newer spec.
Agent readability score
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
Agent readability score
Strengths
- Tool names are generally descriptive and indicate their primary function.
- Detailed cost information is provided for each tool, aiding resource management.
Weaknesses
- Some tool descriptions lack explicit use cases (e.g., 'dependency_risk_score' does not clearly explain when to use it).
- Parameter definitions in some tools are ambiguous (e.g., 'market slug' without context).
dependency_risk_score— Incomplete description truncates critical information about hallucination checks.crypto_sentiment— Description cuts off mid-sentence, leaving sources and methodology unclear.token_price— Parameter 'mint address' is clear, but no mention of optional parameters or validation rules.
Verdict
Event narrative
Risk: medium
- 2026-09-10T21:16:35.016Z — era changed from auth-gated to legacy, complianceScore increased from null to 100 · transition to stable legacy mode with complete compliance
Advice
Schema compliance
tools/list structure, inputSchema validity, and a functional smoke test — the components of the 0-100 score.
- tools/list schema valid
- inputSchema is valid JSON Schema
- Smoke test not run this round
- Cold-start: cold 398ms → warm 400ms (penalty 0ms)
Availability history
Each block is one measurement round. Green: working response. Amber: responded but the server was returning errors (5xx). Red: no response at all.
