LST Tools

Overview

LST (Liquid Staking Token) MCP tools let AI agents interact with Endur liquid staking on Starknet. When users stake STRK, they receive xSTRK — a liquid token whose value appreciates as staking yield accrues.

⚠️ Critical: Endur LST yield is embedded in the share price. Do not call claim_rewards for LST positions — there is nothing to claim. Use lst_redeem or lst_exit_all to realize yield.

Tools

`get_lst_position`

Property	Value
Type	read
Description	User's liquid staking position — LST shares and equivalent underlying value

Input Schema:

Parameter	Type	Required	Default	Description
`asset`	string	❌	`STRK`	Underlying asset symbol

Response:

{
  "asset": "STRK",
  "lstToken": "xSTRK",
  "shareBalance": "100.0",
  "underlyingValue": "105.7",
  "exchangeRate": "1.057"
}

`get_lst_stats`

Property	Value
Type	read
Description	Endur LST protocol statistics — current APY, total value locked

Input Schema:

Parameter	Type	Required	Default	Description
`asset`	string	❌	`STRK`	Asset to query

Response:

{
  "asset": "STRK",
  "lstToken": "xSTRK",
  "apy": "4.85%",
  "tvl": "$12.5M",
  "exchangeRate": "1.057"
}

`lst_stake`

Property	Value
Type	write
Description	Deposit into Endur liquid staking (e.g. STRK → xSTRK)

Input Schema:

Parameter	Type	Required	Default	Description
`amount`	string	✅	—	Amount to stake
`asset`	string	❌	`STRK`	Asset to stake
`simulate`	boolean	❌	`false`	Dry-run without executing

`lst_redeem`

Property	Value
Type	write
Description	Redeem a specific amount of LST shares back to the underlying asset

Input Schema:

Parameter	Type	Required	Default	Description
`amount`	string	✅	—	Amount of LST shares to redeem
`asset`	string	❌	`STRK`	Underlying asset
`simulate`	boolean	❌	`false`	Dry-run without executing

`lst_exit_all`

Property	Value
Type	write
Description	Redeem entire LST position for a given asset

Input Schema:

Parameter	Type	Required	Default	Description
`asset`	string	❌	`STRK`	Asset to exit completely
`simulate`	boolean	❌	`false`	Dry-run without executing

Agent Best Practices

Check position first — Call get_lst_position before any action to understand current exposure
Never use claim_rewards — LST yield is automatic via share price appreciation; calling claim will fail or yield nothing
Use get_lst_stats for APY — Always check the live APY before recommending liquid staking to users
Simulate first — Set simulate: true on stake/redeem/exit to preview fees
Explain the yield model — Inform users that xSTRK value grows over time, so redeeming later yields more underlying tokens

CLI equivalents: LST Commands — lst-position, lst-stats, lst-stake, lst-redeem, lst-exit-all
