## Quality 79/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: simulate_transaction (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); gas_price (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); payment_info (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 567 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 6, about 567 tokens to load them all
- tool set hash: 02965759fd6870f665faddea817da2a7
- badge: [![protogrid quality](https://protogrid.dev/badge/io.autosophia/base-lens.svg)](https://protogrid.dev/servers/io.autosophia/base-lens)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (6)

- `gas_price`: Current Base gas price. $0.01 per call. Typically returns in under 2s.

Returns base fee, priority fee percentiles from the last 20 blocks, congestion
read, and three recommended (slow/normal/urgent) fee tiers with ETH cost estimate.

- `inspect_wallet`: Wallet profile on Base. $0.01 per call in USDC. Read-only.

Returns ETH balance, nonce, whether the address is a contract or EOA, and
balances of a curated major-token list (USDC/WETH/DAI/cbETH — not full
portfolio enumeration, which needs an indexer on EVM).

address: 0x-prefixed EVM address on Base

- `payment_info`: How to pay, step by step.
- `screen_token`: ERC-20 token risk screen on Base. $0.01 per call in USDC — no account, no API key.

Returns risk_score(0-100), signals, token metadata, and a real Uniswap v3
on-chain slippage curve. Holder concentration and token age are not available
(would need an indexer) — marked "not_available", never guessed.

address: 0x-prefixed ERC-20 contract address on Base

- `service_info`: Start here. What this server sells and its current limits.
- `simulate_transaction`: Preview a Base call before sending. $0.01 per call. Never sends — simulation only.

Runs eth_call + eth_estimateGas against the given call. Decodes Error(string)
and Panic(uint256) revert reasons in plain language.

to: contract/address to call
data: calldata, hex string starting with 0x (default empty call)
value: ETH to send along, hex wei string (default 0x0)
from_address: address to simulate as sender (optional)
