What gala_launchpad_sell does on Gala
AI agents invoke gala_launchpad_sell to trigger actions in Gala. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
| Parameter | Type | Required | Description |
|---|---|---|---|
type | string | Yes | Trade type (must match what you used in calculateSellAmount): - 'native': Receiving GALA amount - 'exact': Selling exact token amount. |
amount | string | Yes | Amount to sell/receive. |
tokenName | string | Yes | Token name. |
privateKey | string | — | Optional private key override for this operation (format: "0x" + 64 hex characters). If provided, uses this wallet instead of the default MCP server wallet. |
expectedAmount | string | Yes | Expected GALA output amount from calculateSellAmount (REQUIRED). CRITICAL: This is the 'amount' field from calculateSellAmount result, NOT your input amount. |
slippageToleranceFactor | number | Yes | Decimal format (0.05 = 5% slippage). |
maxAcceptableReverseBondingCurveFee | string | — | OPTIONAL: Base reverse bonding curve fee from calculateSellAmount (GALA), result.reverseBondingCurveFee. The ceiling sent is this fee plus maxAcceptableReverseB |
maxAcceptableReverseBondingCurveFeeSlippageFactor | number | — | Optional slippage tolerance for reverse bonding curve fee (decimal, e.g., 0.01 for 1%). Defaults to 0.01 (1%) if not provided. Applied to maxAcceptableReverseBo |
Parameters from the server's own tool schema.
Why gala_launchpad_sell is rated High
gala_launchpad_sell triggers real processes with real consequences. An agent gone sideways doesn't fire it once. It starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.
Attacks that exploit this kind of access
The rule that runs gala_launchpad_sell safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Gala, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For gala_launchpad_sell, this is the rule to start with:
gala_launchpad_sell stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Gala, apply this rule, and every gala_launchpad_sell call is checked against it from then on.
Questions about gala_launchpad_sell
Execute token sale with slippage protection. WORKFLOW: 1. calculateSellAmount() -> Get expected output (result.amount and result.reverseBondingCurveFee) 2. sell() -> Execute trade with expectedAmount (and optionally maxAcceptableReverseBondingCurveFee) 3. fetchTrades() -> Verify trade completed - result.amount -> expectedAmount - result.reverseBondingCurveFee -> maxAcceptableReverseBondingCurveFee (optional: when omitted the SDK quotes the fee itself and allows it plus 1% slippage) RETURNS: Transaction details including input/output amounts and transaction ID. It is categorised as a Execute tool in the Gala MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
gala_launchpad_sell accepts 8 parameters: type, amount, tokenName, privateKey, expectedAmount, slippageToleranceFactor, maxAcceptableReverseBondingCurveFee, maxAcceptableReverseBondingCurveFeeSlippageFactor. Required: type, amount, tokenName, expectedAmount, slippageToleranceFactor. The full parameter table on this page comes from the server's own tool schema.
Register the Gala MCP server in PolicyLayer and add a rule for gala_launchpad_sell: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Gala. Nothing to install.
gala_launchpad_sell is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the gala_launchpad_sell rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for gala_launchpad_sell. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
gala_launchpad_sell is provided by the Gala MCP server (@gala-chain/gala-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
