Implementation Reference

• src/handlers/helius.ts:347-354 (handler)

  The handler function that executes the tool logic by calling Helius RPC's getAssetProof method.

  export const getAssetProofHandler = async (input: { id: string }): Promise<ToolResultSchema> => {
    try {
      const proof = await (helius as any as Helius).rpc.getAssetProof({ id: input.id });
      return createSuccessResponse(`Asset proof: ${JSON.stringify(proof, null, 2)}`);
    } catch (error) {
      return createErrorResponse(`Error getting asset proof: ${error instanceof Error ? error.message : String(error)}`);
    }
  }

• src/tools.ts:308-318 (schema)

  JSON schema defining the input for the tool (requires 'id' string).

  {
    name: 'helius_get_asset_proof',
    description: 'Get proof for a digital asset',
    inputSchema: {
      type: 'object',
      properties: {
        id: { type: 'string' }
      },
      required: ['id']
    }
  },

• src/tools.ts:575-575 (registration)

  Maps the tool name to its handler function in the global handlers dictionary.
