## MCP tools (9)

### `resolve_party` (~150 tokens)

Resolve a Canton party

Resolve a human-friendly query (ANS name, display name, or raw party ID) to a canonical Canton party. Returns the party ID, display name, org type (validator / app / sv / unknown), current CC balance, ANS names, and update count. If the query is ambiguous, returns a candidate list to choose from. Use this first whenever the user refers to a party by name.

Input parameters:

- `chain` (string): Chain to query. Defaults to "canton" (currently the only supported chain).
- `query` (string, required): ANS name (e.g. noves.unverified.cns), display name fragment (e.g. Cumberland), or raw party ID (name::hash).

### `search_directory` (~138 tokens)

Search the Canton network directory

Browse or search the Canton network directory of known parties (validators, apps, super validators). Filter by orgType and/or a free-text query. Returns party ID, display name, org type, and current CC balance. Ask "who are the super validators?" → orgType: "sv".

Input parameters:

- `chain` (string): Chain to query. Defaults to "canton" (currently the only supported chain).
- `limit` (integer): Max results to return (default 25, max 100).
- `orgType` (string): Filter by organization type. sv = super validator.
- `query` (string): Free-text search over names.

### `get_balance` (~164 tokens)

Get a party's balance

Get a Canton party's CC balance (total, locked, unlocked) with USD values — current, or at any point in time via the optional date. "What was X's balance on January 1?" → date: "2026-01-01".

Input parameters:

- `chain` (string): Chain to query. Defaults to "canton" (currently the only supported chain).
- `date` (string): Point-in-time balance: ISO date (2026-01-01), ISO datetime, or unix timestamp. Omit for current.
- `party` (string, required): The party to query — accepts an ANS name (e.g. noves.unverified.cns), a display name (e.g. Cumberland), or a raw Canton party ID (name::hash).

### `get_balance_history` (~159 tokens)

Get a party's balance history

Get a Canton party's daily CC balance series. Each row is the end-of-day (UTC) snapshot for that date. Defaults to the last 30 days when no range is given.

Input parameters:

- `chain` (string): Chain to query. Defaults to "canton" (currently the only supported chain).
- `endDate` (string): Range end (inclusive): ISO date, ISO datetime, or unix timestamp.
- `party` (string, required): The party to query — accepts an ANS name (e.g. noves.unverified.cns), a display name (e.g. Cumberland), or a raw Canton party ID (name::hash).
- `startDate` (string): Range start: ISO date, ISO datetime, or unix timestamp.

### `get_rewards` (~269 tokens)

Get a party's rewards

Get a Canton party's mining/validator rewards. Three granularities: "summary" (default) — current earnings metrics (latest round, 1h avg, 24h avg, incl. post-traffic-cost CC/USD); "daily" — per-day totals over a date range (max 90 days per call); "transfers" — individual reward transfers. Optionally filter by rewardType.

Input parameters:

- `chain` (string): Chain to query. Defaults to "canton" (currently the only supported chain).
- `endDate` (string): Range end (inclusive): ISO date, ISO datetime, or unix timestamp.
- `granularity` (string): summary = current earnings metrics; daily = per-day totals; transfers = individual reward payouts.
- `limit` (integer): Max transfer rows when granularity is transfers (default 25, max 100).
- `party` (string, required): The party to query — accepts an ANS name (e.g. noves.unverified.cns), a display name (e.g. Cumberland), or a raw Canton party ID (name::hash).
- `rewardType` (string): Filter to one reward type (transfers granularity only).
- `startDate` (string): Range start: ISO date, ISO datetime, or unix timestamp.

### `get_transactions` (~285 tokens)

Get a party's classified transactions

Get a Canton party's transaction history, classified into human-readable types (transfer, mergeSplit, validatorRewards, appRewards, svRewards, buyTraffic, issueCoupon, redeemCoupon, paySubscription, validatorLicenseActivityReport, …). Returns compact rows (id, time, type, roles, transfer summary) sorted newest-first. Use get_transaction for the full payload of one update. Set includeCount: true to also get the total update count for the window.

Input parameters:

- `chain` (string): Chain to query. Defaults to "canton" (currently the only supported chain).
- `endDate` (string): Range end (inclusive): ISO date, ISO datetime, or unix timestamp.
- `includeCount` (boolean): Also return the total number of updates in the window (one extra API call).
- `limit` (integer): Max rows (default 25, max 100).
- `party` (string, required): The party to query — accepts an ANS name (e.g. noves.unverified.cns), a display name (e.g. Cumberland), or a raw Canton party ID (name::hash).
- `startDate` (string): Range start: ISO date, ISO datetime, or unix timestamp.
- `txType` (string): Filter to one classification type (e.g. transfer, buyTraffic, validatorRewards). Filtered client-side over recent pages.

### `get_transfer_stats` (~152 tokens)

Get a party's transfer statistics

Get aggregate CC transfer statistics for a Canton party: total/sent/received counts, volumes, and unique counterparty count — optionally over a date range.

Input parameters:

- `chain` (string): Chain to query. Defaults to "canton" (currently the only supported chain).
- `endDate` (string): Range end (inclusive): ISO date, ISO datetime, or unix timestamp.
- `party` (string, required): The party to query — accepts an ANS name (e.g. noves.unverified.cns), a display name (e.g. Cumberland), or a raw Canton party ID (name::hash).
- `startDate` (string): Range start: ISO date, ISO datetime, or unix timestamp.

### `get_price` (~158 tokens)

Get the Canton Coin (CC) price

Get the Canton Coin (CC) USD price. No arguments → current spot price. timestamp → historical spot at that moment. startDate+endDate → OHLC series (interval: "hourly" or "daily", default daily). Good for "what's the CC price trend over the past month?".

Input parameters:

- `chain` (string): Chain to query. Defaults to "canton" (currently the only supported chain).
- `endDate` (string): History range end.
- `interval` (string): OHLC bucket size for range queries.
- `startDate` (string): History range start (use with endDate).
- `timestamp` (string): Historical spot price at this moment: ISO date, ISO datetime, or unix timestamp.

### `get_transaction` (~98 tokens)

Get one transaction in full detail

Get the full classified detail of a single Canton update (transaction) by its update ID, including the complete payload: classification, all parties and roles, transfers, values, and raw transaction data. Use after get_transactions when you need everything about one update.

Input parameters:

- `chain` (string): Chain to query. Defaults to "canton" (currently the only supported chain).
- `updateId` (string, required): The update ID (from get_transactions rows).
