Set Gas Price

Stop here.

Parse the JSON output. Show the user their current settings:

• Gas price (token and amount)
• Gas multiplier (if set, otherwise "default: 1.5")
• Active chain

IMPORTANT: Do NOT read ~/.manifest-agent/config.json directly — it contains the key password.

Step 2 — What to change

Use AskUserQuestion to ask what the user wants to change:

• Gas fee token — switch between available tokens (e.g., MFX, PWR)
• Gas multiplier — adjust the gas simulation multiplier (default: 1.5, must be >= 1)
• Both

Step 3 — Change gas fee token (if selected)

Read the chain data file for the active chain:

cat ~/.manifest-agent/chains/ACTIVE_CHAIN.json

Replace ACTIVE_CHAIN with the activeChain value from Step 1.

Parse the feeTokens array. Each token has symbol, denom, and fixedMinGasPrice.

Use AskUserQuestion to ask which token to use, showing the symbol and min gas price for each:

• MFX (min gas price: 1)
• PWR (min gas price: 0.37)

Compose the gas price string from the selected token's fixedMinGasPrice and denom (the raw on-chain denom, NOT the symbol) as <fixedMinGasPrice><denom>.

Step 4 — Change gas multiplier (if selected)

Ask the user for the new gas multiplier value. Explain:

• Default is 1.5 (50% buffer over simulated gas)
• Must be >= 1.0
• Higher values = more likely to succeed but cost more
• 1.0 = exact simulated gas (may fail if estimate is tight)
• 2.0 = double the simulated gas (generous buffer)

Step 5 — Apply changes

Build the update command with the appropriate flags:

node "$MANIFEST_PLUGIN_ROOT/scripts/update-config.cjs" --gas-price GAS_PRICE --gas-multiplier GAS_MULTIPLIER

Include only the flags that changed. For example, if only the token changed:

node "$MANIFEST_PLUGIN_ROOT/scripts/update-config.cjs" --gas-price 1umfx

If only the multiplier changed:

node "$MANIFEST_PLUGIN_ROOT/scripts/update-config.cjs" --gas-multiplier 1.8

Parse the JSON output to confirm the update.

Step 6 — Report

Tell the user:

1. The new gas settings
2. MCP servers need to be restarted to use the new settings
