feat: Add Close/Get Deployment

Add Close and Get Deployment Tools to Akash MCP Server

Summary

This PR adds two essential tools to the Akash MCP server for improved deployment lifecycle management:

• close-deployment - Terminate deployments on the Akash Network
• get-deployment - Query deployment details including status, groups, and escrow

Motivation

The Akash MCP server previously lacked critical deployment management capabilities. Users could create and update deployments but had no programmatic way to:

1. Close/terminate deployments when no longer needed
2. Query detailed deployment information for monitoring and debugging

These gaps prevented complete deployment lifecycle management through the MCP interface.

Changes

New Tools Added

1. Close Deployment Tool (src/tools/close-deployment.ts)

• Sends MsgCloseDeployment transaction to the Akash blockchain
• Accepts deployment sequence number (dseq) parameter
• Triggers cascade cleanup: lease termination, bid cancellation, escrow refund
• Returns transaction hash and confirmation details

2. Get Deployment Tool (src/tools/get-deployment.ts)

• Queries deployment details via RPC
• Accepts deployment sequence number (dseq) parameter
• Returns comprehensive deployment data:
  • Deployment status and metadata
  • Group specifications and states
  • Escrow account balance and payment details

Files Modified

• src/tools/close-deployment.ts - New file (48 lines)
• src/tools/get-deployment.ts - New file (51 lines)
• src/tools/index.ts - Added exports for both tools
• src/AkashMCP.ts - Registered both tools in registerTools() method

Implementation Details

Both tools follow the established patterns in the codebase:

• Use Zod for parameter validation
• Leverage existing wallet/client context
• Return standardized output via createOutput() utility
• Handle errors consistently with other tools
• Match code style and structure of existing tools

Testing

• Successfully builds with TypeScript compiler
• Tested deployment closure on Akash mainnet
• Verified deployment queries return accurate data
• Confirmed escrow refunds process correctly

Impact

These additions complete the core deployment management capabilities, enabling:

• Full CRUD operations for deployments
• Proper resource cleanup and cost management
• Enhanced monitoring and debugging capabilities
• Better integration with infrastructure automation tools

Breaking Changes

None. These are additive changes that maintain backward compatibility.

Checklist

• Code follows project style guidelines
• TypeScript compilation successful
• Tools tested on Akash mainnet
• Documentation in tool descriptions
• Consistent error handling
• No breaking changes to existing tools
