Context Cost

~820Tokens (tool definitions)
~3.7 KBTypical response size
Moderate attention impact (0.64% of 128k context)

This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢 Read-only🟡 Write🔴 Delete⚪ Unknown
🟢preflight_transaction(candidate, constraints)

Before execution: assess one unsigned Base candidate. Free, no wallet/payment. CAUTION commonly means total cost is incomplete; simulation is not authorization or guaranteed success.

🟢verify_transaction(transaction_hash, expectation)

After broadcast: verify observed Base transaction against explicit expectations. Default checks inclusion, NOT receipt success. VERIFIED is not finality, ownership or causality. Free; not-found/provider uncertainty is not success.
