## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__chord__chord_ask` `mcp__chord__chord_candles` `mcp__chord__chord_chains` `mcp__chord__chord_holders` `mcp__chord__chord_lp_pools` `mcp__chord__chord_lp_positions` `mcp__chord__chord_overview` `mcp__chord__chord_quote` `mcp__chord__chord_search` `mcp__chord__chord_smart_money` `mcp__chord__chord_status` `mcp__chord__chord_swap_tx` `mcp__chord__chord_token` `mcp__chord__chord_tokens` `mcp__chord__chord_trades` `mcp__chord__chord_wallet` `mcp__chord__chord_wallet_trades` |

Description, as the server wrote it:

```untrusted-server-text
Ask Chord's analyst a question in plain language (markets, tokens, wallets, perps, macro). Uses many data sources and takes 10 to 60 seconds. Needs an API key.

Description, as the server wrote it:

```untrusted-server-text
The chains Chord serves, with their native asset, anchors and which capabilities each one has (overview, tokens, trades, candles, wallet PnL, smart money, holders, LP, quote, swap). Call this first when unsure what a chain supports.
