Base token facts and ERC-20 allowance checks. Per-call USDC on Base; x402 wallet required.
Scored across 6 tools
The three base_* data tools target fairly distinct things (allowance, facts packet, Uniswap V3 LP accounting), but get_runtime_tools and get_tool_status both expose tool/pricing introspection and are easy to confuse. preview_base_usdc also overlaps conceptually with base_token_facts since both surface USDC on-chain facts.
Names follow two loose conventions: noun-style base_* data tools (base_token_allowance, base_token_facts, base_uniswap_v3_lp_accounting_audit) versus verb-style meta tools (get_runtime_tools, get_tool_status, preview_base_usdc). Still readable, but no single predictable verb_noun pattern.
Six tools is a sensible, well-scoped set for a read-only Base token data server. No obvious bloat, though three of the six lean toward payment/introspection meta rather than core token data.
Covers allowance, token facts, and Uniswap V3 LP accounting, but common needs like token balance queries and transfer/event history are missing. Three payment/introspection tools take slots without filling the core read-only data surface.
