Nobody here has read this server's code, because it publishes none. The description above is the maker's own, from the registry. A connection test shows whether it answers and what tools it says it has; it never calls a tool, so it cannot show what one does with your data.
Where it sits in the directory's order
What can be seen from outside, weighed as the directory publishes.
Observable signals: 45 of 100 points (at most 60 here)
| Input | Points | What was seen |

| Source published | held at 0 | No entry here publishes source: that is what puts it in this directory. |
| Licence stated | held at 0 | With no files, there is nothing for a licence to be stated in or held against. |
| Advisory state | held at 0 | Advisory databases index packages, and these entries publish none, so there is nothing to look up. |
| Auth declared | 0 of 15 | The registry entry declares no key. That is what it declares, not a finding that it has no protection. |

The tools it lists (15, as of 5 days ago)
The tool-description rules found nothing in these descriptions. They look for instructions aimed at a model and for hidden characters; they cannot see what a tool does when it runs.
crypto_priceLive USD price and 24 h change for up to 30 crypto assets on any chain — by symbol, CoinGecko id, contract or mint address. Resolves each asset (BTC, "coingecko:ethereum", "base:0x…", a bare 0x address with chain, or a Solana mint) and prices it from DefiLlama's aggregated oracle (confidence score included). Symbols resolve against the top 1,000 coins by market cap first, so "USDC" means the real one; ambiguous symbols list the alternatives. When to use: For current prices by symbol on any chain; for Solana mints by address use price (on the MAD Synapse · Wallets & Risk server, https://agent.m
price_historyHistorical USD prices for any crypto asset (hourly or daily, up to 365 days) with return, high/low, max drawdown and annualized volatility. Same asset resolution as crypto_price. Returns the series plus stats computed from it: total return, high/low with dates, max drawdown, and annualized volatility from log returns. When to use: For past prices and drawdowns; for the current price (on the MAD Synapse · Wallets & Risk server, https://agent.maddegen.art/hub/mcp/risk) use crypto_price. Price: $0.002 per call (10 free/day; after that a payment-required result lists x402 options). Errors: returns
defi_rankingsTop DeFi protocols by TVL (or 1 d / 7 d TVL change), filterable by chain and category — lending, DEX, liquid staking, bridges, perps… From DefiLlama's full protocol list (~6,000 protocols). Each row: TVL, TVL on the requested chain, 1 h/1 d/7 d change, market cap, category, chains, site. Use for "biggest lending protocols on Base" or "fastest growing DEXes this week". When to use: To rank protocols; for one protocol in depth use defi_protocol. Price: free. Errors: returns isError with a message for invalid input or an upstream failure (not charged).
defi_protocolOne DeFi protocol in depth: TVL by chain, TVL trend, fees and revenue (24 h/7 d/30 d), market cap, audits, links. Look up by name or DefiLlama slug ("aave", "Uniswap", "jupiter"). Combines DefiLlama's protocol list with its fees/revenue summaries. Fuzzy name matches return the best match plus close alternatives. Price: $0.002 per call (10 free/day; after that a payment-required result lists x402 options). Errors: returns isError with a message for invalid input or an upstream failure (not charged).
How this entry becomes a listing
For the maker. The catalogue lists what it can read, and this server publishes nothing to read yet. There are two routes, and only the first is open today.
Publish the source Open today
- Put the server's source in a public repository on github.com, with a licence.
- Keep a server.json in that repository naming this server,
art.maddegen.agent/synapse-chain, and declare the repository in it:"repository": { "url": "https://github.com/owner/repo", "source": "github" }, adding"subfolder"when the server lives in a folder. - Publish that version to the official MCP registry.
- The nightly registry sweep records the declaration. This page stays, dated, and says the source is declared but not yet read.
- The catalogue reads declared repositories at a pinned commit, in batches run by hand, and lists the servers that meet the batch's rules (among them a server.json at that commit naming the server, an https endpoint and a licence). When it lists this server, this page links to the listing. There is no schedule, so no date can be promised.
